I am just replying back from my thread in the Street Racers Corner.

Congrats on the dyno!!!

I knew your car needed it because if mine picked up some on a stock motor, then I knew yours needed to be dialed-in.

Now that I know your dyno numbers, gearing wise, I would go with 4.10's on your car. This will allow you cross about 300 rpms over your HP peak in 4th gear while using a 26" slick. About 5,800 rpms or so. This is assuming you will stay N/A. But, even if you go poweradder, just get 28" slicks to cover the extra MPH. *If you stay with 3.73's, you won't even get to your HP peak in 4th gear. You will cross the traps at about 5300 rpms. Of course, just try it out first with what you got and see how it goes. I am sure you will be happy with the results either way.

If you got slicks, then get ready to get a roll bar installed, because you will surely be in the 11's with a good launch. I know a guy with a 93GT with 295rwhp that ran 11.98 @ 112 MPH, race weight of 3200 lbs, and with a good launch on BFG Drag radials. So, launch hard, drive it like you stole it, and reap the benefits. Just don't blow the rear out like me!!!

My car only dynoed 298 rwhp @ 6300 rpms and 294 rwtq at 4700 rpms. My race weight is 3290 lbs. with me in the car. And look what I ran.

FYI, my dyno numbers are alittle low because of my 4.56's and the entire rearend was built the day prior and due to friction from not being broken-in made my numbers show up lower than expected. But, they still aren't near yours though. Mine are actually just over 300-305 rwhp and rwtq.

Keep me updated on your progress.

Later, Jason
