How do I make my 600 fazer faster?????

[mr self destruct]

I think maybe high lift cams would also make the engine more peaky? (i.e. less torque/mid range but more top end revvy). That's about as far as my understanding goes, and I'd be interested to hear from someone who really knows what they are talking about!

A higher lift but equal duration cam gives engines more low end torque, as a rule it's the duration and overlap that give an engine more top end power.


A good explanation is here:

Something to note though, is with higher duration cams there's more valve overlap, which is why engines with cams like that run like shit at low rpm.

Although the rules on overlap on the site change with forced induction; you don't need as much because the turbo or supercharger is forcing the mixture in, so can minimise it at low rpm.
