Default First Time Dynoed

Evening everyone... Just had my 93 w/auto trans (39k on the od)dynoed on a portable Dynojet. 253.4 hp and 286 tq. Mods done so far are K&N open air filter, air foil, and a cat back Magnaflow exhaust with an x-pipe.
Any advise to get a little more?? Haven't taken it to the track yet, any predictions?
Something I noticed today, the tires would not break loose on the 1-2 shift. After I did the exhaust the car did it all the time under WOT. And I'm talking more than just a chirp on black top. Now I don't drive her all the time but I can't see that causing any probs. One time it felt like I was on the rev limiter (was not shifting manually), wondering if that could be the opti starting to go. Any advice on that would be great. I hope its not the tranny (then again it might be cheaper then an opti replacement.... LOL!!!

I predict 13.8 on your first pass since you've never been to the track before. By the end of the night you might get it to high 13.4's or low 13.5's

My 94 6-speed with 95K miles with only a cut lid did 273 hp and 309tq. Did 2 pulls with A/F, and they wheere pretty much the same on both pulls. I was mighty suprised.

Probably close. Again, it depends on your gears. 2.59 or 3.07?

I have a 3.07 rear end.

Question for Trizney... 273 is damn good with only a open air. What kind is the open air?? I heard the a manual trans car will make about 7 to 10% more power over a auto equiped car.

Its the cut lid, that has the raised lid with the openings on the top and bottom to allow more air. I would go look at the specific brand, but it is in the shop getting 4.10s installed and Hurst Short Throw.
