Nitrous power causes engine WEAR - RUBBISH!!!!!

[ScoobyDoo]

Wasnt sure where to post this, but since Bren has fitted NOS to his I'd thought Id post here.....

Is this guy correct?

I cannot take that posting seriously, he says
"The points listed below are ALL FACTS
They are NOT MY OPINIONS. "
They are not "FACTS" just one person's opinion. If they are "FACTS" where are the references of the information?
I'm not saying I disagree or agree with anything he is saying there about NOZ, but his opening line is a cheap ploy to dissuade people from disagreeing with his comments ...

Of course it causes engine wear! To use the NOS you have to have the engine running which causes wear.... um....

It'll put more strain on the engine but I don't see why it should wear faster unless something is knackered already or you're constantly caning the engine (bear in mind I'm not a mechanic).


The final BUT MOST IMPORTANT point that 99.9% of people seem to forget or overlook, is that Nitrous is ONLY used for a few SECONDS at a time. So even if ALL the
above was RUBBISH, this very short use period would have such a microscopic effect on wear that it would NOT be worth considering (which is why I don't make a big thing about Nitrous actually REDUCING engine wear).


Detonation (so I read on here somewhere) can knacker stuff in only a few seconds (if it's bad enough), as could running the engine at 15k rpm. Just cos it's happening for a short time doesn't mean its not damaging anything

Read through some of it, and it appears to be part bullsh1t, part true.
Detonation can do massive damage to an engine very quickly. I have a video to prove it (Its an NSX on the dyno that goes bang a few seconds after the nitrous is applied).
Point 1 is entirely true.
Point 2 is part true part false. Yes wear increases as revs increase, but it is not linear as he suggests, or you could rev any engine to 15k RPM, and only do triple wear that you would at 5k RPM.
Point 3 is mainly bollox. Get a high power nitrous system, and apply it at low revs. watch a rod go through your block!
Point 4 is intertwined truth and bollox
point 5 is well in theory right. In reality it depends.

All of this os of course, IMHO.

This is the best bit


The best way to reduce camshaft wear is to run the engine at higher rpm because the cam lobes and followers are not in contact for as long as when running at low rpm. The faster you accelerate the engine to high rpm the shorter the time that the followers are in contact with the cam lobes.

PMSL

And apparently camshafts wear quickly coz they are made from a hard material :rolleyes:

Nos probably does infact cause little wear. What it does cause tho is big noisy messy failures on already worn engines, this is caused by the sudden increase of power produced and high stresses in the combustion chamber. Thats why the main failure in cars with Nos is rods leaving the block by the nearest exit.

On a turbo car det is virtually eliminated with nitrous. Ive posted why in my big nitrous thread on the main page. Im running nigh on 400bhp on a completely standard SR20DET so i think if det was an issue it would have at least killed one (inherently weak) iridium plug by now. Highpower swear that the ignition system will give up the goast and Id be getting the spark blow out before det became an issue.

A n/a car is a different issue.

You will do lots of damage if you introduce high levels of nitrous at low rpm. If you introduce the gas progressivley as it revs out there is little chance of damaging a rod if you stick to sensible limits. Again I point to my own car as an example.

Maybe with a wet system, but not necessarily with a dry system.

[bren]

Youd have to be completely brain dead to use a dry system ;)

[Actual_Ben_Taylor]

:p Yes, but nobody has mentioned which type of system we are talking about yet...

Wet, dry, single port, direct port... They all work differently and they all have different effects on the engine...

[Martin T]

I wouldn't use any NO2 apart from a fogger system. The rest are just a bodge.

[andyf]

I like the sound of the nos FOGGER system. I don't know why, it just seems to appeal to me on a very low level.

[Martin T]

Hmmm cant think why;)

Something to do with Fast and Furious perhaps?

Whys that then? What nitrous systems have you experience of?

[Billy]

Arrggghhhh! :eek: :eek: :eek:

It's like Mycroft has multiplied and started taking Largactyl......:sleep:

Where does he get off, Nos doesn't cause wear? It might cause less wear than the revs you'd need without it, but it's hardly the same thing....

"Most engine wear occurs at start-up" Bollox. The highest RATE of wear occurs at start-up. Again, not the same thing...

"Camshafts wear less at high RPM." Unbelievable bollox of the worst kind. It makes no odds what speed the cam goes round, it still spends the same time in contact with the follower, just in a different number of events. (If the time of contact had such a major effect, surely the cam would wear faster when the engine was stopped.:rolleyes: ) Joking aside, I get the feeling that he's mis-understood why cams wear fast at low revs (we're talking idle speed here, where the "ramp" of oil that the cam pushes in front of it has time to dissipate thus allowing metal to metal contact.) and has come up with some balony to justify his supposed understanding. According to him, opening a valve twice as fast will reduce the load on the cam.
Truly a wizard. :notworthy :notworthy :notworthy :tosser:

The bit about cams causing most wear is probably true (though not always, depends what they're made of, and as for roller cams...) but combined with the above point to produce the mutant, "Nos reduces the cam speed rise time and hence wear" is just silly.

I'm not saying the guy knows nothing about what goes on inside an engine (though "Nos chipping the carbon off the pistons as a cure for smoking" decides it for me) but he has absolutely no talent for putting it into English and should do himself a favour before he becomes...


The Scarecrow of Nos!

I forgot to add IMHO to the last comment:rolleyes:
Personally I have not used Nitrous before, and I'm no expert, but AFAIK there are basically dry, wet and fogger systems. A dry syatem runs lean when the Nitrous is being introduced:eek: , but runs right at full blast
Wet system runs right when winding up, but rich at full blast, losing power, but a lot safer.
A fogger system uses a different type of nozzle, and uses an ECU etc to make sure its running right the whole time.
To me, dry and wet systems seem to be a bodge allthough respect to the ppl with the guts to put nitrous on at all!
This is by no means a definative list, and is not based my personal experience, but my brothers friends (i.e. I could be talking shit:D )

I think Billy should post that on his forum ;)

[docwra]

Is there anything Billy doesnt know?? ;)

I know nothing about Nitrous, but a wise man once said to me:
"The candle that burns twice as bright, lasts half as long"
Thinking about it, I think it was Billy ............ :rolleyes: ;)

I was tempted, believe me!

Soon changed my mind when I realised there were at least another seven pages of drivel to wade through though...:rolleyes:

Who you callin' a wise-ass, meatball......? :finger:

It's just a case of simple maths.

Which the guy seems to have no comprehension of :rolleyes::tosser:

[astraboy]

I've been running N20 on the astra since august 2000.
When I get it back from its welding, I need to do an engine rebuild as the piston rings are gone on #3.
Had a lot of fun in the meantime though. :thumbs:
Draw your own conclusions gentlemen...
