Ok, this might be a long story.
Took the newly aquired GN (87) to the track last Friday. I wasnt happy enough. It's basically a stock car, with only a K&N, slightly better injectors (not sure which, but they appear to have blue stripes), new turbo-inlet and MAF pipe. The friend I bought it from had never really beat on it at all, but said it -should- turn a high 13. With this in mind, I dumped about 5 gallons of Sunoco 94 octane in the tank (to about half tank), and took it on down. I have only raced one of these cars once, that was a friend of my fathers. He was turning 13.9's in it. I launced with too much boost and it spun, fishtailing to a horrid 2.8 second 60' time, and a 14.6. Obviously I have a lot to learn, even though I've studied these cars for so many years.
Only managed two passes, since it was so crowded with rice at the track, but my second, and best run was only 14.55 @ 93.41. Street tires & stock GN rims. The first run was a tad slower, and I figured it might have spun, but that wasnt the case. I tried to launch with more boost, but I cant read the gauge [aftermarket one in console] cause it was dark and not wired to lights. The 60' time improved from a 2.2 to a 2.1, so it obviously wasnt spinning. It wont hold too much w/o breaking the tires loose, as they started to while the amber lights were tripping down.. I launched with it in OD, which I shouldnt have, and I didnt use the TCC lockup at all because I just plain forgot to flip the switch.
With those two things in mind, I'll try those next time, but is there anything I can do to improve on this? Stock turbo and stock chip. I was thinking of trying out a Thrasher chip for now,.. maybe the 92 so I can run it on the street. However, I have stock fuel press reg, and they specify the need for an adjustable or one of the others. Any boost tips? Reasons why it wont hold much on the line w/o spinning the tires? Cheap tweaks, or no-cost tweaks I can do under the hood? It may be holding a few psi honestly, but as I said, I cant read the gauge in the dark yet. Any tips are welcomed.
Also: It is a heavy car. Fully loaded with p/w, p/l, p/seats,....
