As i said depends on too many things.
my 1600 cvh running std comp ratio is 175psi on std cam, times to 104 degrees, 155 psi at 112 degrees. and 165psi on kent 35 cam @ 118 degrees.
All on same day, using same tester and method, with booster connected.
He's running a larger turbo, on un set up car, and unknown engine C/R, IT NEEDS SETTING UP.
Cheers for the reply's but its not always just get it set up, ive spoken to lots of engine builders today and 2 rolling roads and they all said the same it should be no more than 150psi and with it at 180 its to high and causing it to pink, one rolling road was torque of the devil and chris todd told me this as he's done loads and he said he wouldnt touch it until the comp's been lowered
m8 if the mappers good at his job ( there rae a lot of crap mappers out there) tehn you could run a turbo engine with high comp and no det how do you think wrc cars run also look at andy nicolls rover c/r 10:5:1 and he runs 35psi on a gt35
