Can anyone tell me cheep but effective ways of squeezing a bit more out of vauxhall turbo engine.
I already plan to put a weber ajustable fuel regulator on and ive already got a 4x4 cossie intercooler, lightened flywheel, 2.5" straight through exhaust and a filter and turn the actuator up a little which should give me a bit more, is there any other tricks I can do which wont cost much or is a really sensible mod etc.
Do you know how much boost you're running in overboost, and how much it holds?
You need a dyno run really, to see what's happening.
Due to the cool charge under boost, you may be stretching the fueling - checking the air/fuel ratio at full boost will show this.
A rising rate fuel pressure regulator would then cover you nicely.
errrrr would love to send you a pic of the intercooler on my car....... but itercoolers and c20ne 8 valve engines dont really work together the turbo engine wont be going in for about three weeks, then im gona run the standard inter cooler for a month or so until i plum in the cossie cooler,
