    Question Does the turbo work in reverse?

    Just thought of this, hmm I would imagine it would. God I am bored.

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

    I dunno, some people...

    Cheers, Phil (also very bored but stuck at work 'til 18:30)

    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

    If you don't have a hamster there it will boost.

    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

    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)

    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!!!!!!!

    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

    On a serious note, yes it does, 'cos my DV sounded after a high speed bit of reversing the other day

    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...

    Just spent the last 5 minutes crying with laughter CWL
    That's just sooooooooo funny
    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
