Re: gt4 to date...

nah mate, stock internals good for around 350-380bhp... ive even seen some people run 400bhp with good cooling... the fmic i have is the same as fensports gt4 with 600BHP!! cost me a small fortune! lol

makes my 1.2bar seem pretty puny!
as for the ecu, that shall have to be one of the next changes if i go much further, the stock ecu can only map itself up to around 18-20psi which is slightly more than im running now, the 540cc injectors are plenty at the moment, but any more than 380 and the duty cycle might be higher than id like it to be.

so long as the cooling is kept well then it "should" stay in one peice! lol

to be honest i only run .8 bar most of the time, i have my controller set up at 4 stages, i have .8 , .9 , 1 bar and 1.2bar so fun mode basically! :D
also has off which runs boost at actuator setting which is around 0.6bar if you want to go dead slow. lol
303.7bhp @ 1.07 Bar :D 301lb/ft toque. :O = :D happy me
