1.1 bar with bpu

iam now just 0.1 bar short of hitting 1.2 bar with my bpu completed...... should i make restrictor ring bigger???

No

You could if you have not already got one, buy a boost controller to raise the boost.

and then take of restrictor ring??? , ps running fmic too

No. Keep the restrictor ring in place and use the BC to raise the boost.

Up and down and all the way round.................... then flick.

what bar are you running mate?

what bar are you running mate?

Zero, I sold my nightmare. However when I was BPU I only saw 0.9 bar and that was with a 1.2bar restrictor ring in place It depends on the car tbh, just because you take out the cats and add a restrictor ring it does mean you are alwaus going to hit 1.2 bar.

ide leave as it is..... when the weather gets colder itll prob boost to 1.2 anyway.... its also better to be on the safe side too...

DOnt want those tubbies to go

Don't touch the restrictor ring. The boost may depend on the engine and turbo's history.

At what speed (in leptons of course) did you hit 1.1 bar?

Turbo's condition dependent of course you won't actually see much power increase from 1.2 to 1.2 bar. In fact you may actually start to lose some power with older turbo's as you start to force them to work outside their efficiency range. Basically the further out of the turbo's efficiency range you get the more heat is generated. This heat is what kills things. My last car put down its best power at 1.15 bar. Power tailed off after that. The 1.2 bar figure is just a generalisation and won't be correct for all cars. Yeah the turbo's may be safe at that pressure but that doesn't mean they are optimimum at that pressure. If you really want to go for it get a boost controller and set it up on a dyno properly.

I'd second that, I'm going to change my 1.2 for a 1.0 ring as when cold I've seen it boost up to 1.3, which may have been the cause of my blow out.

Not worth it boosting to those levels when you don't want it to, trust me.

If the temperature is low enough to make the car boost then the temperature is low enough to avoid detonation. A short spirited drive in cold temps isn't going to blow a turbo that wasn't already weak.

50 - 100 mph

I average 1.1 but if i go out on a cool night i can see it creep upto 1.2 after a few seconds on wot but i have to be moving fairly quicky to get the cool air to do its job.
