Re: crower stage 1 cams
 

Those numbers are for lift...what's the degree of overlap? Overlap in some setups can be useful, such as on a log-style manifold that has little scavenging going on and can increase the scavenge effect. On most tubular manifolds overlap will end up robbing power.
Just a side note, I know you have to replace your springs and associated ---- in order to run those cams in your b16 (due to b16 spring coil bind). Might be other parts involved (such as valves if stems are longer on hype-r setups or gsr's) but I'll leave that to you to research.

i'm running a ramhorn manifold ..i just put itr valve springs and retainers in. let me see if i could find them numbers for the overlap

Re: crower stage 1 cams
 

so how much over lap dose a stock cam have
what would be better for vtec on a stock z6 log or horn

Re: crower stage 1 cams
 

Stock cams have a little bit of overlap, but not much. A ramhorn style manifold will scavenge much better than a log, but is it really going to be worth the price for a few extra hp on a stock motor? For the under 300hp just go with the tried and true log, much cheaper and who knows...maybe that little bit of overlap will help out after all.

Re: crower stage 1 cams
 

slightly off topic: on the end of the cam with the part number.... is the "-2" there or no?


on topic...i will be putting bigger ones in my turbo B16A :-*

Re: crower stage 1 cams
 

my boy is running the crower turbo cams, stage 2. these are some mean cams. vtec engages like wtf! I used the same cams for a month. they was some really great cams throughout the whole power band. especially 6500rpm - 9600rpm.

the stage ones are better that the ITR ones so you got a great deal for free. use them with no hestitaton.

Re: crower stage 1 cams
 

well im about to make a new manifold for a bigger turbo and its going to stay on when i build the engine so i might as well go ram horn
plus its $50 more in bends and fabing time so i think its worth it

Re: crower stage 1 cams
 

i email crower to ask them what the overlap was on the cams. they said the overlap is 22.5 degrees of overlap on the VTEC lobe

Re: crower stage 1 cams
 

The bigger the boost the more I like aggressive NA cams.
