if you've run more than recommended 1 bar on stock turbos, your results were...?

Running 1 bar, rare overshoots to 1.3... No problems as yet (touch wood!).

i think the poll is reading wrong

1 bar, and over 1 bar without any problems should be two seperate options

how long have you been overboosting like that?

No idea (only had the car one month); whenever I look at the boost controller/guage it sticks at 1 bar no worries but the peak display function shows 1.3 ish...

ran mine around a year on 1bar and blew the exhaust wheel clean off the rear turbo thank **** it all went down the exhaust.Still got the remnants of the exhaust wheel as it got stuck in the back box :chuckle:
I think it is a case of when will they break rather than if they will.

was running 1.3 to 1.4 on ceramics for a good few thousand miles and never blew. they run very well
Quick but a lottery ticket ! :chuckle:

R34 engine and turbos, fitted decat which causes them to over boost as the waste-gate is too small to expel the pressure !
Result < totally trashed engine and disillusionment with ceramics.
Even now, when eating cereal out of the bowl I expect it to shatter and take out the rest of the building !:eek:

You can run more boost out of them than the recomended 1 bar max but depending on how fit the turbo's are to start with depends on how long you'll be making boost!

Best to be safe!

I have to ask, why risk blowing engines & turbos by running a car higher than 1 bar?:rolleyes: Surely your asking for trouble?:eek: :confused:

I suppose because people like me want to go faster than we can really afford to! This thread is interesting, as I cant afford to upgrade turbos yet, but obviously want more power than 1 bar gives. I also like to prove wrong the "you cant do that" brigade

But how long do you stay right for? Surely its cheaper and less trouble to buy better turbos, than to have a rebuild?:popcorn:

cokey, you're hilarious

ru' don't worry about the peak figures, i run mine at 0.9 and if you watch the gauge it stays there solid, but occasionally spikes to 1.1 especially if i'm in 4th or 5th gear.

Yeah the Gtr 34 is differant ,if you put free flowing exhaust on and de cat pipe you need to fit a 60 mill (it think thats the size) restrictor ring just before the decat to stop over boosting .
