I had the AR Headers and Hennessey Intake with tune done, and the results are pretty much as expected.
521 HP/483 TQ, rear wheels. These numbers are pretty close to the 522/490 obtained by AR Headers when they dynoed their car. The only significant difference was that they got a 50 TQ gain as well (then again, that car started at 440 TQ). I don't know how much time passed between my arrival (after a long highway trip) and when the car was placed on the dyno, but variability in the extent of stock heat-soak levels could theoretically account for some of the differences, IMHO.
The stock numbers on my manual transmission car were 464 HP/457 RW TQ, so the total difference was 57HP/26TQ.
In addition, the post mod, pre tune numbers were 498 HP/479 TQ, and the differences were most apparent after about 3500 RPM, where the TQ curve stayed higher for longer from there to 6000+.
With regard to the SOP feel, it seems a bit quicker, but I drove from Houston (Sealy) back to San Antonio with my 4 year-old in the back, and it was in the high 90's. I'll need to do my routing morning drive to work and back down familiar roads to properly evaluate the difference in feel.
I decided not to go with the Corsas, but instead to leave the stock mufflers on the car. I think I'll end up sticking with that decision; this set-up has a moderate increase in exhaust volume (mostly under load, not so much at idle or highway cruise), but retains the exhaust sound character.
The supercharger sounds changes are significant, and in a good way! The whine is more audible, and the air-rushing sound is cool.
Anyway, I'm pleased with the sound and dyno changes for these conservative mods. At some point, I may do the pulley, but I don't want to be without the car for a whole week (this is my daily driver).
