much appreciated man, surely will swap cams before vortech install. supercharger will arrive tomorrow. v3 self-lubricated system, and custom intercooler.will post pictures and video of dyno when all is done. thanks again for the input.

not a problem

good luck on everything, the car will feel like a new animal for a bout a week, then you will want to start going with smaller pulleys for more power. Trust me...lol

Actually i'm in the same boat as you. I'm wanting to run a Vortech + meth with my PI MHS stage 2 n/a cams. Long story short...i've talked to both Nick and Mark Chacon (head grinder at Bullet) and while Nick isn't too sure, Mark doesn't recommend it. Granted my specs are a little different than yours, but when the time comes i'm gonna give it a shot anyways. My logic mind tells me that it really shouldn't matter too much with mild boost like 9-12 psi, but who knows lol.

As far as your cams go you have a tighter ICL, but looser ECL, so it might actually work better than mine to be honest. The exhaust lift and duration really shouldn't be too much of an issue IMO. You have more total exhaust emphasis on your specs compared to mine (which is what you want with a blower to avoid heat build up) so if i had to guess i would think they would do fine.

the only thing thats way out of wack is LSA, like said 106 is pretty narrow, blower cams usually like 112+

I hear what you're saying, but actually his LSA is 109. His intake centerline is 106, which would put the exhaust centerline at 112. Certainly not ideal, but since the exhaust centerline is pushed out a bit i think he'll probably be fine.

OP, i'd ask Nick just to be sure though.

On a stock internal setup with stock pistons/valves they will probably just recommend a stage 1 blower grind
+ fvcking one, never understood why people buy off the shelf cams for built cars when custom grinds are the exact same price.
