well according to nx the 125 shot is what the power is suppose to be at the wheels. the shot at the engine will actually be more. the torque will be hard to figure out.but the hp will be around the 270ish area.im running a 150 shot. so at the flywheel for example it is near a 175 shot.

Kenny,
Hp doesnt fall. it actually looks like it is still rising, but ever so slightly.
Tq starts falling off at @ 5,000 rpms, and by 6,000 rpms it is at 247ish.....

01 Thunder: Good numbers! I bet that cam has a ton of under the curve hp/tq. What are you shifting at with it?

Last weekend I had 289 rwhp with 22 degrees of timing & 390 rwh with 401 ftlbs of torque on the bottle. I hit 289 with with 32 degrees of timing, & 2 hours of wideband tuning on the hwy with the z06 cam. I made the same with the comp 212/218 cam with 22 degrees of time with much more usable hp. I would bet I could have hit 300 + on a-cold day with unlimited dyno time. after I put the bottle on it I backed the timing down to be safe, with the new valve springs & some extra timing I could have gotten more. it makes power through 6400 rpm's.

corrected info with thread above. I would bet the ZO6 cam would have been a better nitrous cam, wider lsa & more lift
