It's been a while since they came out, and ive only seen one or two dyno's, is there a formed opinion now and proof of the average horsepower/torque the stage kits put out as well as their dyno graphs?

 

GM Stage II with an Intake on a Dyno-Jet is pushing about 250whp. I've seen a couple dynos. On Mustang dynos, the same setup is pushing 222whp.

 

I was planning on posting up the comparison graphs, but it seems I had a tank of bad gas or it was just too warm yesterday because the car dyno'd in at 232 whp and 205 tq, and I really believe the ecu pulled timing because of that to prevent knock.

I was extemly disappointed since my stock dyno was 223 whp and 190 tq. The improvement in the tq number seems to be right but the hp is way off since other ppl with stage 2 and nothing else dyno'd in at around 245. I was hoping for around 250 since I have an Intake on as well.

I'll prolly go back in a bit and do another run just to make sure though

 

WOW...cool!

 

so the general consensus is that the stage 2 puts down to the wheels what its rated at from gm at the crank?
