Postby alti on Sat Oct 25, 2003 6:20 pm

hello!i´m from germany and have a 2,0 zetec turbo.i´ve lowered the compression with a plate of 2,0 mm.it´s 8,5:1 cr.
my question:

with how much boost can i drive to have no fear of detornation?

at the moment i drive with the originale ecu 130hp.@4bar fuelpressure.
i´ve got a 5th injector wich i put it by 5psi into.is this correct or drive it to lean?

urm detonation aint really your prob, if your running standard pistons this will be the limits of how much boost u can run, not alot lol. u can put how much fuel u want into it, u still aint got forged pistons that are designed to run with high pressures and heat that a turbo engine gives out

nearly 60psi fuel pressure, bit high innit lol, as your running a standard ecu, don`t expect it to last long as fueling will be way out. u need a mapable chip with ofab(turbo ecu) or aftermarket management.
