dyno is way low
ok just got off the dyno and pulled 414/419.
this is with a 233/239-112
fast 102
long tubes ( no cats)
stinger exhaust
CAI
this is an LS2 car with low miles.
with long tubes and a CAI it pulled 380/383
anyone see a problem with this?
the cam has 14* of overalp and sounds damn near stock
opinions?

I only made mid 420's with my old LS2. Kooks 1 7/8 headers, no cats, full 3" exhaust, FAST 90, Volant CAI and a 242/248 111lsa cam. Your numbers seem realistic to me. Go run it and see what it MPH's.

yea the TQ being higher than the HP is strange to me. never seen this with a cam only car.

with 14* of overalp i thought this thing would sound like a dragster. but it sounds like a hot cam.
something has to be wrong here

these numbers sound exactly like what you should get with all mods except the cam.
the cam was new in the box and i just looked at the old cam. it has marks from being used. so i must have put in the new cam.
if it was degreed wrong would it have this effect?

Phil at AI told me it happens all of the time...thats why he offered to measure my cam for free (I just paid for the shipping). The cam was spot on (Thanks Kevin a Schneider Racing Cams).
As far as dynos go, my first dyno got me 314 rwhp...bone stock (mainline dyno)!!! Its just a tool...

That cam, as specced, isn't in your motor. As specced, it will sound and behave WAY different vs stock. I have a Comp cam that is going on a cam doctor next week. It's a mild boost cam that sounded OK, but made very little power. The measured boost is 3 to 4psi over what I thought it should be. I know it's not what I ordered. Big boost and little power.....hmmm.
