What you classing as high comp Mike?
everytime i see a cossie spec its always got low comp, between 6.8 and 7.*:1 whereas the jap lads all seem to run around 8.5:1 generally.
What difference does it make if theyre both ran on say Shell V-Power? How come it works on Evo's etc but not on cossies, even though they both run decent boost levels?
I understand the theory behind detonation but the 8.5:1 compression doesnt seem to cause any problems over on the darkside, but scares the shit out of the ford boys
It dont scare me but remember I am also on the darkside
