thanks guys for the replys , i just have a go ,regards intercooler it suports 450bhp , ive run/boosted the engine up to 27psi ,lol before the crank let go , and found out why , it was the dam engine sump ,, as i used a mk3 vr6 sump bolted on to the mk4 engine and i wasnt aware the oilpickuppipe was basicly flat to bottom which caused oil starvation grrr , so ill be useing the alloy one this time , (ill just try and have to watch out for speed humps ,,Dude! Epic! Fair shout for custom making everything! There's getting mods done, then there's making mods!
Good luck with the Caddy - what a beast when you get it done!
Will you not need a bigger intercooler for that sort of power?
