r34s running 1.0 bar and up...minor setback

[toby19]

just wanted to get anyone's feedback on air filter to turbo pipes sucking in on 34 GTT's running approx 1.0 bar and up (especially on hot days). This was featured in one of the issues of HPI (Project R34).

I dialled up boost to over 1.0 bar recently. However at approx 4000 rpm the engine suddenly cut off. I am quite sure it's soft pipe connecting the afm to the turbo that's the culprit. Does anyone have any other suggestions on how to cure this. These are a few of them:

-Pull out the hose and get it reinforced with aluminium piping

-Insert a coil spring inside the rubber pipe to keep it from sucking closed at

high vacuum levels

-etc

Have anyone of you R34 owners come across this problem?

I wouldnt put a coil in the hosing incase the turbo swallows it. Maybe as a tempory soloution put a coil on the outside of the hosing and attach it with some glue or something. Then perhaps when you get an fmic change the piping to alloy.

I thought the stock R34 GT-T turbo's couldn't really take 1 bar? Plastic wheels or something like that? I thought i read that somewhere, u couldn't turn the boost up too much.... not 100% tho..

I'm running 1.2bar (new turbo) and not getting that problem (although it's little bit colder here!). I'm looking for a hard pipe kit tho' as I don't want it too happen.

I had the same problem with my 200sx. I found under load the intake pipe was folding in on its self. ......................

solution...................custom pipe.....

Maybe as a quick-fix aproach, you could wrap the intake pipe with fibre glass gauze, and resin. You'd have a fairly rigid pipe. But for a better result just get one made up out of alloy.
