cams

[ekg]

Will performance cams increase the chance of headgasket goin? Should it be uprated before they are fitted?

[fred]

No, dont bothered unless you plan on raising the compressios with either new pistons or forced induction. Even then its not essential.

[ekg]

ok and is it a good idea to have the cams in for abit before a remap?

[mikey_b]

probs a good idea to run them in gently, you dont want it going on the rollers fresh as it will be being pushed pretty hard

[fred]

Yea like mikey says, just let them bed in. RR is a harsh enviornment.

[ekg]

couple of hundred miles? or not that much

[fred]

Yeah a tank of petrol taking it easy :)

Also use cam lube when you fit them to help with the first start up before the oil has found its way to the top of the engine.

[ekg]

ok thanks for the advice. The mechanic should do that cos I wont be fitting them. not confident enough.

[mikey_b]

tell him just to make sure, better safe than sorry :)

I've heard people being told to run them in for about 1000 miles before having a remap.

ive been running them in, done about 150mile so far, all is good i suppose not thrashing her to an inch of her life, they can take it anyway, ill let ya know difference on wednesday
