How much psi?

[ausgtr]

Afternoon guys,

I was just wondering what sort of boost i can run with the stock twins on my R32 GT-R? The only modifications are the 3" exhuast and a bigger HKS fmic. During some high speed runs and accelerating through the gears it hits a maximum of 0.7 bar, or 11psi (you can tell i'm an expert:p ). So what's the limit with the TT's with my mods?

Thanks in advance guys.

Stewart.

The boost limit is governed more by the exhaust wheel than by any mods. If you still have the ceramic type exhaust wheels in the turbos, then there isn't a lot of room to move as far as more boost goes. When over-boosted for too long, the ceramic wheels have a tendency to part company with the shaft, and either end up being spat out the exhaust, or ingested back into the engine (and the ceramic is a wonderful cylinder honing material :eek1: )
