Accralite 1.5mm oversize pistons
 

HI, I have a doubt about the pistons Accralite 1.5mm oversize pistons, this compression is 7.8:1 , which pressure turbo, maximum reliable, can I use with this compression ratio? my car has intercooler AIRTEC large, H-beam THS performance uk, OFAB management, cam piper t285 t2 and garrett t3 turbo.
And what power can I get? :DD:
Regards

well the turbo will max at around 20-21 psi so run it at "max" ad see what results you get. im asuming you are useing the correct chip for your spec?

I am considering using one of a cosworth t34 soon , which will be the limit of the pistons with that turbo? I was in Portugal there is no trainers that I fine-tune the car :wall: is the thing I love and here are very rare rs turbos, have come to a custom chip made of motorsport, which the mechanical refinements necessary? and a custom made chip is ideal for what I have. or must be done even with the car there to be mapped the chip??
