Thats not to say it wasnt already limiting it at that level though, these things tend to be a resistance to making power rather than a limit to making it.
Exactly,you either need a igger turbo blowing more air for longer or a bigger ex cam to hold on to the revs longer..
It all depends where you want your peak power too,in rods case he only needs peak power at the right point of brunters so no need to have peak power at say 8.2k like a track car with low gear ratios..
The std ex cam works really well with around std gear ratios on a road car but is shit in say my race car where i need to rev much higher on lower ratios..
Even on the 549 hp motor the other week its still done its peak by 6.9k iirc so an awesome road car with a really good spread of power..
