I can't decide what I want is really the problem.

Dyno numbers on the 150 pill...
Took the car down to a dyno day today at a local primarily Ford Mustang speedshop. It was the only Chevy there. I was running the 150 jets. It was 100+ degrees outside and the car was hot when it went on the dyno.
It put down 498.59rwhp and 547.04rwtq even though it was pretty rich. Not too shabby for a 85,000 mile LT4 with a hotcam.
I wanted to top 500rwhp...maybe next time when it is cooler. Best part is that at the time I left it still had the highest numbers of anything there. I'll post up a vid shortly. Can't wait to get a clutch in it and get it back to the track.

He is using a kit from www.blazinghighperformance.com. I'm pretty sure they get their stuff from Nitro Dave or Nitrous Outlet, but I'm not 100% sure.

With the nitrous tune (less timing, more fuel) his car runs about .5 seconds slower, so it's probably only making 330 or so NA with the N20 tune.
The hotcam is a 218/228 duration, and with the 10 degree split responds really well to nitrous. I would bet he is picking up more than 150 RWHP with the 150 jets. I had another LTX car with a 383 and a hotcam that made 380 RWHP/380 RWTQ NA with the NA tune. With a nitrous tune it only made 350/365. However, when hit with a 100 shot it made 475/620. 125 RWHP and 255 RWTQ from the 100 shot. My point is that the hotcam really responds well to nitrous.

Nice numbers, I like the way your curve is. Nice power under the curve car, not real peaky curve. In another thread I was guessing at how much my car is losing N/A since it is tuned for nitrous. I'm guessing about 20 at the wheels, but that is a wild guess. It was tuned by Alvin at pcmforless. I'm running a CC503 cam and an HSR intake on a stock L98 bottom with 98,000 miles. It dyno'd 419 rwtq and 417 rwhp on a 150 shot, but that was on a DYNOmite Land and Sea dyno, supposed to be similar to a Mustang dyno. How does that compare to a Dynojet? I'm at 13.2 air fuel ratio when N/A and at 12.5 air fuel ratio on the nitrous. Does that sound about right? I have no detonation or anything. Don't mean to steal the thread or anything, jonecap and neat, you guys seem to know alot about this stuff.
