its a regrind cam
intake dur 290 lift 490
exhaust dur 280 lift 480
112 deg lobe sep.
I used .230 lash pads to get the wipe pattern to look good.
The first thing that seemed strange was I has to lean the entire map out, even in boost. The vac at idle was 21lb, now its 9-10lb. It just seems to not have any power unless your using the turbo? When the turbo does hit it feels good, and seems to make power above 6200rpm (thats as far as I have pushed it)
I had the cam gear in the #1 hole, I changed it to the #3 hole. It might of made a diff. but I'm not sure?
My timing at idle is 30deg, goes up to about 40 until boost, then drops to 24 at 17 lbs boost with the meth spraying.
All in all it just is not as powerful before or after boost than the stock cam? It revs higher, but thats about it??
Am I missing something? Thanks
