Boost?
Interested to hear what boost levels you guys are running? My car is being run in at the mo & will be remapped at end of Jan. Previous owner says it will be OK to run 2bar ...
Cheers, TX.
PS - spec is CDB, forged pistons, MD321T turbo etc.

2bar is alot of boost. Some people seem to get infactuated with running high levels of boost.
The key is to find a turbo spec that meets your power goals, ideally without having to run such high boost levels. For some builds this is not an option, but for 95% of us it is.

Mine has reached 2 bar, due to a hose failure, but is mapped to 1.7 bar with cold weather overboost to 1.8... std 2002 STI motor.

On a freshly rebuiilt 2.35 (under 200 miles) with fully built up heads, i think i saw 535hp @ 1.7 Bar - granted that was using some WI, but quite a safe AFR (similar to yours)
So, i guess you're not really much down on power (but should be able to find some more with a bit more boost
)

What do you run yours at fella (realize that it's a bit "special") + what do you think is a reasonable level for any particular turbo?

I don't how restrictive the exhaust wheel and housing is on a MD321T, but i couldn't run more than 1.65Bar on a 2.35 with MD321s - Upping the Boost Valve Duty Cycle didn't make the boost go up at all.
That setup made 496hp with Water Injection
