Quote from: Air TGPyeah when it was running it got a 15.89 at dragway 42, but 3rd gear went out and the i was driving it to my shop to fix it and the head gaskets blew, needless to say its just sitting untill i can come up with time and money to fix it. hey 90 TGP i saw you car a couple fridays ago out at Quaker for the stop light drags.

Well if you get the car fixed and bring it to the track again...when the tree starts coming down (assuming you're not bracket racing, because this will not net you a good reaction time) brake torque to about 3k...because if you take too much longer than that the computer will pull timing and boost until a little bit into 2nd gear (from what I've found)...but with the stock chip brake torquing is necessary to pull of decent 60' times, so you definately need to do it.  Also, hold the car in 2nd gear to 6000-6100rpms because this will put the engine closer to the powerband in 3rd when it shifts.  Those two things should help you out a little.  Also, try putting a K&N filter on the turbo (the stock intake is very restrictive as you found out), and put new plugs in it (I use AC delco R42LTS plugs gapped at .042")..this should gain you some time.  Also, try dropping the exhaust..if you pick up a lot of time your catalytic convertor is probably plugged/partly plugged and should be replaced or gutted.  I have heard that some TGP's only run low 16's stock, but from what I have found, they can all run mid 15's with decent plugs, wires, intake, and most importantly of all, driver skill, mine went high 14's...you just have to do all the proper maintenance and at shorter than recommended intervals.

well i started workin on the head gaskets and i got a set of 3.1 heads and i did a little port and polish job to them and i'm going to put 1.6 rockers on it also. and the exhaust rusted off while sitting this summer so i'm gona run a straight pipe from the turbo back. i;m also going to see whati can do about making my own crossover and possibly putting a bigger turbo or maybe respooling the orgional.  i'm also working on some ram air set up from under the car.
