I ran with the cutout open and no air filter.
I'm going to do a tune-up on it this week and run again this friday and see what kind of times i pull.. I feel I can pull a 13.7 if I launch harder. My buddies 93 T/A went 13.7 with subs and about 200 lbs in tools laying in the car and 155k mi.. he only had SLP LM1 Catback on it. So thats my goal for this week. I'm going to Atco Raceway... if any1 lives close you should come

also.. any1 have any input as to how i should launch or how long to heat up the tires (street tires 245's)

 

Towards the later runs, it looks like you nailed some pretty good times for a near stock, higher mileage LT1. Nice job.

 

thanks man.. that was my second time ever racing at the track... i ran my v6 1 pass last year sometime. 16.95 LOL

 

nice breakin into the 13's is a good feeling....

 

I'm jealous....I want 13's, lol. Your automatic helped in the 60' alot compared to my times....still learning how to launch with a 6 spd ---

 

Don't worry.. you can get 13's next time you go to the track. My buddy has a foxbody 5 spd, and he said he launches at 4k and feathers the clutch so he won't spin so bad. I've seen him get 1.6 60's with BFG DR's! Keep practicing man!

 

i want high 1.8's or low 1.9's 60ft times when i go this summer

 

You can either launch right off idle, or bring the revs up a little (around ~800 - 1000 RPM which will be much easier on the rear diff .

As for heating up the tires, you're pretty much wasting your time/tires doing so with streets . Until or unless you get drag radials, start with the pressure up around ~35 - 36 psi, only do a quick spin to "clean them off" if you want to, but a burn-out won't help.

Congrats on getting into the 13's though A few of my friends have hit them with stock or close-to-stock LT1's, while a couple haven't .

 

I did a 13.88 but I don't feel that's good enough for my car

 

i kno a kid with the exact same mods as u and runs consistant 13.7's on street tires so ur close to ur mark....o plus he is an auto... just work on ur shifts and wait for good weather

 

13.7s are fully within your grasp. If you guys would just invest in a set of Drag radials it would make your life much easier and track runs more fun. It takes alot of the driver error out of the run.

 

I'm definately getting some 15" rims in the near future, and I want to pick up a set of ET streets.. I'm doing a tune-up as soon as the plugs I ordered arrive (NGK TR-55s). Anybody know what plug wires I should go with? I'm going to run the car next week to see if I can get a 13.7.

 

MSD wires are pretty good

 

Agreed . One of my buddies was able to cut a 13.8xx with his bone-stock '97 Z28 M6, but after we bolted my BFG DR's to his car, he cut a 13.7xx .

Oh yeah, line-lock can be helpful too!! (only if you've got slicks/DR's to heat up though)

 

line lock or some good brakes....either way... just heat up them tires
