Default Finally took it to the track

I went to Firebird this Friday for the first time( first time ever being at any drag strip) and after a couple of runs I got a best of 13.9 at 101.2 with a 2.25 60'. I figure it's not half bad especially after watching other guys run. Next mods are definitely going to improve traction haha. Any tips for launching though? my sweet spot was about 2500rpm

You can also improve your time by a couple tenths if its a stock cam by shifting close to 6000 rpm.

Only advice I have is don't feather your clutch. Don't side step it either. Both will result in failure of something soon enough. Just let the clutch out quickly still using the pressure of your foot. You just need to find a sweet spot and it will change from outing to outing depending on track temp and traction compound. If running street tires I wouldn't bother with a burnout. I'd avoid the waterbox and just dust them off. Street tires have a lower temp tolerance in turning to greasy goo if they are heated up too much. If using a drag radial I'd only do a few seconds of a burnout. Too many people think the higher the temp of the tires the better they'll grab. It's not true and they perform far worse if they are overheated.

I cut a 1.31 on a very short burnout.

Didn't know u could do that stock. That would have helped a bit. I've always been told to just dust off the tires. I don't think any amount of heat would let my tires launch higher than 2000 without screeching

doing a burn out on street tires deffinetly doesnt benifit you. I found that if I just went up and ran it was the best on street tires...im sure youll be told many different things about it.

Keep at it. Youll get better. M6 cars are the hard ones to drag race, any stick shift is really, consistancy is very inconsistant lol, but some people have it down to a science and know exactly what to do.

Never driven an LT1 car before. But is it safe to say you won't get much better than a 13.9 out of it?

With 11 year old GSCs that couldn't hook for crap, my best was a 13.96 at 100.8 with a 2.2 60 foot. I wish I had known I could hold it to 6k too Its been over a year since I ran, but I seem to remember shifting just before the tail end of the track, and wondering if I could've held the RPM...

I ran that with just a CAI and a 2OTL. I imagine just adding my fresh 275s, I could be more consistent and at least get down into the 13.7-13.8 range. I either hooked or bogged that day...

I feel SSRR has given some very sound and experienced advice! I would like to add to it aswell being a 6speed Guy, set your tire pressure when the tire is warm I generally set my rear tires (radials mind you) at no less than 22psi, the fronts I air them up to 50-55psi for 2 reasons
1. Much less rolling resistance (air them down to drive home)
2. Every 10psi. up front is similar to 20lbs. being added to the rear.
Stick cars are VERY tricky to launch on ANY tire especially radials with little sidewall so PRACTICE is your best friend.......as far as the burnout box STEER AWAY from it!!!!! I like to go around the box find the groove in the track line up straight then back up about 2-3 feet short of the burnout box and do a short burnout pretty much just cleaning off the tires and roll up to set the first bulb(pre-stage) set the stage bulb raise the RPM up to about 1500 and let the clutch out as if you were leaving a stop light then lay into the throttle...
What ever you do don't get mad if it does not run a killer time you have to focus on YOU,CAR,CLUTCH PEDDAL and the Throttle......practice and practice you will begin to drop your 60' times..... Good job so far bro!

Thats not really true. My 103,000 mile LT1 only has a catback, gutted cat and CAI and I just ran 13.65@101 ,2.0 60' with 22 psi in 245 street tires

Some better tires I'd say you're looking at mid 13's at 103 mph. Which is pretty respectable for your mods. With full bolt on's, low low 13's. Nice times. Also if your looking for a good timeslip, get in behind a car in the staging lanes with some big slicks. Generally they put down some great rubber to launch on off the line.
