Of course I doesn't 'cos the air is going through the engine the opposite way!

I think the ecu is set to prevent this from happening
I think you'll find that the vanes are shaped so it spins in one direction only.
No it doesn't...
When you select reverse the following sequence happens..
1) The gearbox gear position nodicator flangulates the precise positional input whirlygig frequency to the barbar valve.
2) The barbar valve compresses this flangulation into a nurfelbyte of terra informational transport system (T.I.T.S.) standard oscillation
3) This engages the turbocharger brake.
4) The turbocharger brake is a long rod that lives in the primary section of the exhaust. On the turbo end of this rod is a small asbestos hamster
5) When engaged, the asbestos hamster hangs onto the turbine wheel with all his strength to stop the turbo spinning
*Note:
the asbestos hamsters on the 200sx are not particularly strong. If you hear a graunching noise when you select reverse, its not the gear synchro's meshing, its actually an asbestos hamster getting caught up in the spinning bits.
Don't worry though, Nissan addresses this problem by fitting a lifetime's supply of asbestos hamsters. The large box section of exhaust just before the rear axle contains over 5000 asbestos hamsters.
If you need to replace them, the Nissan part number is:
8088390-001
Alternatively, Nismo do an uprated hamster called 'Hyper-Rodent-R'
So now you know
OMG!
thats the funniest thing I've read ALL day!

Just to clarify - is that an 'asbestos hamster' of a conventional hamster in an asbestos suit?
You have just caused me major embarassment as the 2 other people left in the office wonder why I am finding inputting bridge survey information funny enough to just about have tears running down my face :) :D
Cheers, Phil
Clarification:
Asbestos Hamsters...
Normal hamsters can't wear asbestos suits thick enough to keep out the huge temperatures encountered just downwind of a normal turbocharger turbine rotor.
These hamsters are drop forged from grade 307 aero steel first, then electroplated with asbestos and teflon (to stop them sticking to the sides of the downpipe)
That is sooooooo funny - i'm pissing my self!! Just the though of a little hamster all kitted out with goggles, gloves etc with a big bar in his hand standing next to a huge spinning fan!!
I've had an HKS "AHCD" (Asbestos Hamster Cut Defencer) fitted to my ecu so the hamster does not know when the car is going into reverse. This way I can actually get 15psi going backwards and get scrabbly!!!!!!!:D
Does that mean that you get Geese in a Mongoose, and as well as stopping the Turbo when you reverse, they flap their wings and aid airflow :D
On a serious note, yes it does, 'cos my DV sounded after a high speed bit of reversing the other day :D :D
Sounds like you've run out of Hamsters then Pete?:D

Seriously sounds like you've run out of Asbestos Hamsters. They are 'lifed' at 24 miles per rodent.
Therefore, you should have enough hamsters to see you to 120,000miles.
If you've not got to 120,000 then its possible you've got a blockage.
Sometimes the hamster refresh mechanism will try and force two down the pipe simultaneously. Due to the fact that they're drop forged steel, they don't bend or squish and will simply jam themselves somewhere between the hamster magazine in front of the back axle, and the turbo.
Get under the car and look for any abnormal bulges in the exhaust pipe.
To fix this, simply go to the silencer end and shout one of the following down the exhaust;
"Oooooh look, there's Richard Gere"
or
"Well I never, its my old mate Bobby Davro"
That'll shift em soon enough
And in answer to the other one, no you don't get Geese in Mongoose's - thats just plain ridiculous...

Now I know why you have to decat when you fit a BOV....
If you don't then instead of hamster being harmlessly ejected through the exhaust, the poor chap ends up going through the BOV and you end up with a dull thud on the underside of the bonnet possibly leaving a small hamster shaped dent:D

They have to put a restrictive little grill in to stop the cat stalking up the downpipe to catch and eat the poor little Asbestos Hamster.

everyone at work is giving me funny looks - could be cos I've fallen off my chair laughing!!!!!!
My hampsters are fine right now - never got boost while reversing :)
The Hamster is also the cause of Turbo Lag:
When you put your foot down this happens
1) The floorit rotation spangulator widget attached to the throttle body reverberates a pulsed fusion signal to the barbar valve.
2) This overides the flangulating positional input whirlygig from the gearbox positional nodicator
3)The barbar valve wibbles the wobble socket which closes the circuit on the Hamster Control wire. The Wire is connected directly to the rodents ar5e
4) A 14 Terravolt 'pulse' is sent down the wire causing the hamster to 'let go' of the turbine rotor
This obviously takes time, hence the delay in you putting your foot down, and the blower spooling up
Maintaining your Asbestos Hamsters:
It should also be noted that the Hamsters are not serviceable items, and repair kits are not available - so don't bother opening up the Hamster Magazine in front of the rear axle. In the Haynes manual, replacing the Hamsters is 6 Spanner rating job, and should not be attempted by anyone. Ever.
If you diagnose Asbestos Hamster Failure on your 200, simply replace the magazine.

I think that I have a rogue Asbestos Hamster, during periods of high boost there is a distinct squeeking sound coming from the hamster magazine / turbo area. Conventional wisdom suggests that the problem is due to a faulty ballbearing in the turbine, however now that I am armed with my new SXOC hamster knowledge it is clear that a renegade hamster has wedged himself into the compressor housing and is gaining cheap thrills from the ensuing vibrations.
Does anyone have a tech guide on how to remove the reluctant rodent?
As already stated:
Rogue Hamsters can be dislodged by the following procedure:
"Oooooh look, there's Richard Gere"
or
"Well I never, its my old mate Bobby Davro"

Nah, I'm only on just over 90,000 miles, but I have removed my standard exhaust and replaced it with a Mongoose. My Mongoose exhaust does not have the middle silencer where the hamsters are normally located.
Does this mean that I need to replace my standard exhaust centre section to get my hamsters back? Or do Mongoose supply uprated 'performance' hamsters that live in either the front or rear silencers?
Please help as I am very worried ;) :D :D :D
Drop forged asbestos hamsters are very expensive.
So expensive in fact, that some ｣23,495 of the final list price of ｣24,999 of the 200sx was due to the fitment of asbestos hamsters.
Without hamsters, the 200sx would have actually cost ｣1504 before haggling and part-ex.
It is highly unlikely that Mongoose even knew about the Hamsters, let alone provide any.
Why not ask Mongoose?
Given that they offer a lifetime guarantee on their exhausts, the pipe may only come with a solitary hamster, again with a lifetime guarantee. If that hamster fails, then you're stuffed.
Traditionally, only the very high end Japanese tuners make any attempt to replace or upgrade from the standard hamsters.
As I previously outlined, Nismo do a Hyper-Rodent-R upgrade.
Like for like specs are:
Standard Hamster:
Grade 307 Drop Forged Steel construction
Reinforced front paws
8Mhz onboard CPU
Hamster Control Wire Connection with 14 Terravolt capacitor
Teflon and Asbestos Electroplated
Nismo Hyper-Rodent-R
Grade 507 Aerospace Drop Forged Magnesium Alloy Honeycomb composite construction
Reinforced front paws with Carbon Fibre brace bars
Air-to-Air Blow-off system
144Mhz Onboard CPU
'Hamster Timer' 2 minute cool down capability
Hamster Control Wire Connection with 14 Terravolt capacitor
*Note: The Nismo Hyper Rodent is fully FIA certified.

No, no, noooo
Somebody has supplied you duff info regarding Mongoose exhausts...
Mongoose is their name, derived from what they contain!
A 'standard' Asbestos Mongoose was found to be a more cost effective alternative to sourcing an 'uprated' Asbestos Hamster.
Hence the Mongoose system continue to be cheaper than imported Japanese exhausts.
Now obviously the Asbestos Mongoose (TM) is a fair bit larger than a Hamster, hence the larger diameter of the exhaust pipe. They are also tough little buggers, hence no need for a Mongoose reservoir, and the lifetime warranty offered.
Less obvious is the quicker spool up you get from a Mongoose equipped system, entirely due to the well known high intelligence of mongeese. This is even more so for Asbestos Mongoose (TM), which have to be specially trained at the factory, hence the sometimes hit and miss delivery, and long order lead times...
This training, and higher 'IQ' means that Asbestos Mongoose (TM) can learn to anticipate the Hamster Control Pulse and so release the turbo that bit sooner.
An additional advantage is that an Asbestos Mongoose (TM) allows higher boost settings, as with it's higher weight and sharper claws it can hang on much tighter than any Asbestos Hamster, which can often be shot out of the standard exhaust if the boost level is to high (hence the need for the Hamster reservoir).
The only slight disadvantage with the patented Asbestos Mongoose(TM) system is that some users have found an increase in the amount of smoke expelled under hard driving. This is an unfortunate side effect of dispensing with the Hamster reservoir - usually the exhaust fumes are fed into the container, allowing the Hamsters to breath, where their little lungs filter out the smoke.
Obviously a single Mongoose cannot provise the same amount of filtration, especially during gearchanges when addition heavy breathing has the danger of hyperventilating - this is not necessarily 'fuel-cut' as some people believe, but the Asbestos Mongoose hyperventilating, getting a bit confused and stopping the turbo at the wrong time.
I hope that has enlightened you all, as to the care that goes into a very fine British product.
Cheers, Phil
So if I understand this correctly... if the Mongoose exhaust has the new uprated Asbestos Mongoose (TM) then the HKS Super Dragger must have an Uprated Type R Asbestos Hamster in DRAG???:D:D:D:D:D:D

No - only Nismo Exhausts are compatible with the Nismo Hyper Rodent R
The Mongoose has its Asbestos Mongoose
The HKS pipe relies on the HKS system uses the Asbestos Hamster Cut Defenser
Junn Auto have developed a twin system relying on speed of response using two Sequential Nitrogen Cooled Titanium Field Mice

OH dear god, I've just read the rest of this thread and I can barely see to type the tears are running down so hard. This is without doubt THE funniest thread EVER EVER EVER written :D
Dave
/me taking a copy incase it goes walkies ....
After reading this thread i diagnosed the massive boost i was getting in reverse as a faulty hamster problem (or FHP)
So i drove down to the local pet store, was very careful in reversing into the parking space though!!
i went into the shop and enquired about a set of forged hampsters. But the bloke had no idea what i was talking about!?!?!:eek:
I think he was keeping them for himself.
Anyway, i decided that id try some standard hampsters instead, you know, just to keep the boost quite low in reverse until i can source some uprated hampsters.
So i bought 5, thought that would do, tried pushing them up the zorst, but they seemed unwilling to do this. So i unbolted the K&N and just threw them down the pipe.
Is that the correct way of fitting them, because its not really boosting much at all, in any gear now?!?
Can hampters be car specific, ie: a 200sx hampster?
They didnt come with instructions so i think i may have put them in incorrectly.
One more thing, ive heard about a single koala conversion, the article said somethin about better air flow and reduced lag by using just 1 large koala instead of many hampsters. Has anyone tried this??
The standard Hamsters you procured from the pet store were not suitable for the 300deg + conditions likely to be found in your exhaust.
They would have worked for a brief period, but only if you modified their backsides to accept the Hamster Control Wire Connection with 14 Terravolt capacitor.
In all probability, the 14 Terravolt pulse probably killed them before the exhaust got up to temperature and fried them.
I tried the single koala conversion, but found that it caused too much lag. When I reversed, the boost would spike for a few seconds before dropping back to zero.
I'm not sure if this was because the koala is bigger than a hamster and therefore slower moving, or that the 14 terravolt pulse wasn't enough to make him move sufficiently quickly. Maybe I should try increasing the voltage of the pulse?
Or do Nismo do a Hyper-Koala-R uprated koala?
I also found after fitting the koala that my car needed 1 litre of Fosters (the 'amber nectar') to every 10 litres of Optimax in the tank to make it run properly. :D :D :D
>I tried the single koala conversion,
Me too, but I switched back, because I got sick of the exhaust fumes smelling of Eucoliptus leaves.
Ah so when I give it go a good thrashing an bits of brown fluff come out on my exhaust then its not baffle at all its the odd expired hamptser making its way out. This explains alot, wish they had taught me that when I was in college it would have made alot more sense.
i think that 14 terravolts is not enough for the koala conversion, ive calculated that you need precisely 1.21 Gigawatts to run a koala at 100% efficiency. This would decrease the lag you get when you reverse hard, so you wouldnt get that age old problem of boost spiking, then falling to 0.
P.S if you do try this conversion, make sure you prune the nails of said koala, as their claws tend to be sharp, and can damage the ceramic blades of your turbo. :rolleyes:
I Recently read an american article associated with the problems of the hamster and an American Engineering firm has recently released a lower technology version of the Asbestos Hampster.
Although the American engineers have gone "back to basics" with the 'hampster' deactivation method and are instead using a Choke chain directly attached to the wibbling wobbler and instead of the usual rodent, a Kevlar coated, CNC mandril bent and turned chipmunk (Kevlar Chipmunk).
Not only is the mechanical method of notification better and quicker, as the chipmonk is able to resond much better to the analogue input of the chain rather than the linier response the elctrode give, but due to there slightly smaller size and also the nimbleness they are able to reduce lag much more efficently by scampering out of the way quicker, but also manage to hold the turbo when reverse is engaged even before the turbo is allowed to spin up!
I can post full specs from the press release if anyone is interested?

Contrary to popular belief, it was not fully asbestos suited, there were no goggles or gloves....the japanese domestic market hamsters must be genetically modified to withstand much higher temperatures.
AH, its a ninja hamster, I believe the origin is tibetan, and as a result have gone through much training and mind power to resist heat.
AS they are also super fit, they are a little leaner than your average hamster and far more effective against boost in reverse, though the Chipmunks have been proven to outperform them!

so after reading this thread i have deduced the problem i had with my s13, the guy sold me what i thought was dodgy hamster , it was wearing dark glasses and lurking in all the wrong places, when i asked it to spin his iccle wheel and get the turbo flying , he replied asylum asylum, the git had sold me an illegal immigrant rodent from kazistan and refused to work his wheel insisting he should get placed in a better car and fed optimax instead of all the cheap stuff, not only this the following day while checking him out the blighter had only let 37 of his close friends and familly in there too who also refused to work, so alas my only option was a mongoose to rid the pests but that failled as it said i eat snakes not immigrant hamsters, so now i have had to sell my s13 and get an s14 with genuine jap rodents who now seem contented and very rarely squeal

always use real rodents not cheap imitations, and a hamster is for life not just for track day
Bump - cos I'm proud of this moment of pure irrelevance.
Hello Dunk, not seen you round these parts for a while :wave: :)
Dunk, did you do the single koala conversion in the end? or did you end up sticking with the stock asbestos hamster?
the reason being that my koala seems to be playing up, and feeding the f#cker bamboo trees is NOT EASY. i have to grind them into a saw dust type of mixture and put it in with the fuel?
Cars been running funny ever since:confused:
Ever since i nicked the koala from howletts, got an asbestos suit made for him, and stuffed him up the exhaust ive had running problems, not to mention the constant phone calls from the RSPCA & pet rescue??
:eek:
should i have trained him? shall i give him a haynes manual to read?
sometimes i think to myself 'wouldnt it be easier to just get used to having boost in reverse??'
sorry to hijack this very useful and informative thread, but i was thinking last night, how the hell do peugeot get 180 BHP out of their NA 2.0L lump. Then i thought of an answer......
there's no way it can be done by internal combustion, because, unless you're a japanese(v clever) person, you would blow the engine up trying to get that amount of HP out it......
It's done using frog's, basically, they are captured from the wild, trained for 1 year, fed constantly on steroids and adapted so that petrol is their only scource of nutrition. Then, they are inserted in to the frog chamber in the engine (formerly known as the combustion chamber, though due to the absence of combustion, peugeot felt it appropriate to rename it), have their toungue attached to electrodes and a fuel line inserted in their ears directly from the injectors. When the valves open, the frogs are forced to inhale the air, as it has nowhere else to go, and just after that, a pulse is sent down the electrode, shocking the frog, this, and the need to expel consumed air, forces the frog to fart and, at the same time extend it's extremely powerful legs downwards, pushing the piston with it at great speed, thus acheiving 180BHP easily.
Feel free to correct me if i have got the wrong idea here, or flame me if i am talking absoloute crap, but i think it's a very reasonable theory:nod: :nod:
Talking abolute cr@p!! have you not read this thread! if it wasnt for Dunk id have never found out about this, cheers mate :)
Mods: could we please have this moved to either s13 or s14 technical please, i feel it will be far more appreciated there:)
you can't just accuse me of talking crap, you at least need to have theory to back it up, after all, we know how much the french like frogs:p
it appears that you have mis read my reply sir, what i meant was that this thread is full of useful information about the workings of engines, so your reply cannot possibly be cr@p as it is in this thread, and therefore it speaks the truth!:nod:
Frogs for engines..... seems reasnoble:thumbs: :wack:

i left the snails out because hey don't really play that big of a part, the snails are moulded to the size of every pipe in the engine and have their shells removed, then they lubricate all the pipework every time the engine is switched off to create less resistance when the air/oil goes through them, thus creating more power:nod:

could the hampster be trained to run round inside the turbo, thus making it a turbo/super charger?
maybe that's why nissan fit two cats, to stop the hamsters escaping down the exhaust
Isn't negative boost the turbo spinning in reverse due to the exhaust creating a partial vacuum when not going out through the turbo ?
no, its when the hampster, whilst holding the blades falls over in his asbestos suit and pulls the turbine blades with him, thus spinning then in the opposite direction....

I feel the need to correct this post.... a watt is a measurement of power, a volt is a measurement of electric potential or electromotive force. The Terravolt and Gigawatt cannot be compared to eachother in this way. If you meant Gigavolt then I'm sorry to say that a Gigavolt is less than a Terravolt. The correct unit of measurement in this instance is a Petavolt.... so 1.21 Petavolts is what's needed to run the koala conversion at 100% efficiency.

Good work fella, made me smile again
LMAO (again) at this thread - does anyone have a link to ARMAGEDDON? It's years since I heard that and cried with laughter every time I heard it:D :cool:
Not a turbo but funny anyway and I had to resurrect this thread for it specially :D

that is quite possibly the funniest pic ive ever seen lol.
mate i :notworthy :notworthy :notworthy to u:D :D :D :D

hang on a minute. i can see the hamster working with a cam belt, but surely the chains would make too much noise and scare them!
i think more investigation is urgently required on this matter.

They source deaf hamsters!;)
Right
For the avoidance of doubt.
The above picture is NOT an asbestos Turbo Brake Hamster.
The small rodent pictured is a hamster.
He's a Traction Hamster and works like this:
1) Individual Wheel speed is monitored by axle Flamscooters.
2) Rotational Wheel Speed differences are compared by the ABS Computer
3) If any slippage is detected (through difference in wheel speed) then the ABS computer sends a signal to a little red bulb mounted inside the Traction Hamsters case.
4) The red light comes on
5) The Traction Hamster starts running in the direction OPPOSITE to engine rotation - thereby reducing power and torque transmitted and reducing wheelspin
This system is a far more accurate method than the traditional butterfly valve upwind of the throttle body.
Really advanced systems are linked to the Turbo Brake Hamster to kill boost and simultaneously slow engine speed.
Traction Hamsters are unique in that they are bred to withstand the massive centrifugal forces are work in their casing. They also have tripled grooved foot pads to ensure traction.
Standard Traction Hamsters are rated to 8,000rpm. Any higher and they 'squish' too far and are unable to regain their usual shape - thereby rendering the TCS useless.
The clattering noise heard above 8,000rpm is not actually valve bounce but the impellor bearings for the hamsters case breaking up under the stress of the hamster pulling 68g and having a centrifugal weight of approx 4.6kgs. In some cases this may cause damage to the mains bearings.
Note that Asbestos Hamsters, and Traction Hamsters are not interchangeable. An asbestos hamster in a Traction Hamster casing will just make a noise like a brick in a cement mixer. A Traction Hamster would simply combust in the Asbestos Hamsters environment.
thanks for the explanation.
what's the policy on the claw length? obviously if the system is used a lot, then their claws will grind down. however careful drivers who don't require tc very often may find claw length becomes excessive. what's the recommended mileage/time to have them clipped?
The service intervals are 12,000miles or 12 months - whichever is sooner.
The service method is:
1) Remove hamster from casing
2) Do not squeeze hamster - it'll make his eyes bulge
3) Immerse Hamster in 'Traction Hamster Cleaning Fluid' and allow to soak for 1 hour
4) Remove Hamster and place on workbench
5) Dry Hamster using Traction Hamster Dryer - if this tool is not available, a hair-dryer will do
6) Trim Hamsters claws using lathe - tolerances are .02 thou to .08 thou
7) Visually check Hamster for signs for stress cracks or breakages - this usually signified by red liquid leaking from cracks in the hamster
8) If all OK, check Hamster balance and orientation systems by taping to electric drill - spin drill at 7,000rpm for 1 minute - then make hamster walk along 1' straight line. No deviation from line means all systems functioning OK
9) Reinsert Hamster
*note* At all times, keep the hamster away from the following materials that are hazardous to traction hamsters
a) Asbestos Hamsters
b) Ice Cream
c) Foxes
d) Cats
e) Sausage Rolls
f) Stairs
g) Tarantulas
This thread has answered many questions... Now I fully understand the workings of my engine.
I have one question though..
Why is the Ptchoooo noise you get when you remove the BOV (the hamsters Breath Outlet Vent) called 'Pigeoning' when it's clearly created by sneezing asbestos hamsters, who are being suffocated due to their air supply being blocked up?
I think that fitting a dump to atmosphere BOV is a far more humane option - when you come off the gas you can even hear the high-pitched hamster sighs of relief...

what about hampster orientation? the original question concerned the turbo and reverse gear, what happens to the traction control hampster when you reverse?
if i reinstall a fully clipped and refreshed hampster, but inadvertantly fitted it backwards, whould i have to reverse everywhere?
is the upgade to chipmunk 2.23 all it's cracked up to be? i would imagine there are problems installing the larger tail module. I understand they do allow for higher speed launches, but then the additional tail/friction situation increases heat.
also should the wheel be fitted with some sort of sump plug? although the photo doesn't show it, there must be input and output connections for the little chappie, otherwise he would starve/dehidrate/drown.
i also read on the honda forum, that vtech engines have contrarotating hampsters, for ballancing purposes. the only problem seems to be maintaining the weight of the two hampsters, as the one nearer the food bowl always ends upweighing more. later models featured equidistant food tubes to counter the problem. just wondering if that is the same system used on the skyline?
your input is much appreicated.

:no: :no: :no:
VTECs have two, but they face the same way. Balancing is rarely an issue cos Hondas use little ones. One hamster tries to stop rotating above 6000rpm, causing the other to hyperdrive :thumbs:

Apparently Mclaren F1 eng have made the traction hamster and the asbestos hamster breed, ( this months F1 Engineering Mag) therefore the hybrid Mchamster ( as its jokingly been called) has been used in testing over the winter to varying degrees of success, DC had more practise, as last year he could have used it more.
The upgrade to Chipmunk 2.2 depends on the configuration you are running, not allways successful and requires frequent reboot.
Scania Trucks are having alleged discussions on using wombats, the koalas proved unsuccesful as the replenish rate from the ko-loader was suspect to failure.

Your all mad :p But oh so funny at this time in the morning stuck on a night shift on a phyciatric ward!! :sleep: (working if you were wondering!!) :D An Jon's right there are definatly 2 hampsters in a Vtec engine :thumbs: Only want one though so need a 200sx :smitten: :nod: :nod: :nod:
PMSL !!!!!!!!!!
thats some funny shit.
i wondered why i could smell soming like roast beef
after i popped a big flame last night.
Where can i purchase a new asbestos Turbo Brake Hamster,
or will Immersing the Hamster in 'Traction Hamster Cleaning Fluid' and allowing it to soak for 1 hour remove the third degree burns?
