Well last friday night I finally got to race my 95 r/t. Need practice launching the car, as I wheel hopped it in first gear,then lifted off the gas, then got back into it and ran a 13.5 at 105 mph. I hope to break a 12 next week if I can launch it right. Any suggestions. Oh my 95 is totally stock, except my high flow exhaust, with 55k miles on the car.

The Pilots do not compare to the kumhos when it comes to traction, Get a second set of rear rims for the Kumhos and put them on for race day :2tu:
In fact I have a spare set of lightly used Kumhos I need to get out of the garage :D , have maybe 5 runs on them. New they are $200 a tire, I let them go for $250 plus shipping. I sold my 96 and my 99 uses 18" BFG's.

Stay out of the water, do a light burnout to heat up the Pilots and clean them off. You should have better grip.
Then you just need to try not to spin!

I remember a stock '94 or so Viper at the Topeka V10 event run well into the 12's. I remember because he would chirp the tires in 3rd gear!! Anyway, I'm also bone stock and as others have said, stay out of the water box. It doesnt do any good with street tires as it will only fill the voids with liquid and cause you to spin. I've got a lot to learn as well but what I have learned is its all in the launch and the 60' times. Adjusting tire pressure front and rear will also help quite a bit.

A few things that helped me:

1. Up your front pressure to maximum and drop your rear pressure to 20 lbs or less. It helps a lot on traction. Just pump them back up before you take any major corners!
2. Next to the launch, slow shifts are the next big killer of ETs. A guy at the track gave me really good advice and although it sounds strange, it really works. He told me to pull on the shifter like you are trying to pull it out of gear while you are accelerating. It won't come out of gear because of the torque on it from the engine, but as soon as you get near the clutch it will fly into the next gear. It's a hard thing to remember if you don't do it already but it really works to improve shift times. Once you have fully launched and are still in first gear, start pulling the stick hard like you are trying to shift into second. Keep pulling and once you let off on the gas and just nudge the clutch it will pop into second very quickly. That's the key shift but you can do the same with going from second into third. It doesn't feel good mentally to be reefing on the shifter when its not yet time to shift but it will sure make your shifting quicker once you master it.
3. Keep on the gas well through the finish line. Lots of guys tend to let up to soon and probably lose a tenth of a second coasting through the last stretch.
4. Practice launches with easing the clutch out vs. dropping the clutch. I've seen some guys get better 60' times one way and other guys get better times the other way. If you are dropping the clutch, figure out the best rpm to do it at. Depending on track surface, temperature, etc. I have had days/tracks where 1500 rpm isn't too low and sticky tracks where 4000 isn't too high.
5. Consider getting heavy duty half shafts if you are dropping the clutch at high rpms on sticky tracks though!

My two cents on a previous post (and no flame intended) is that chirping the tires is not a good thing. It means that you didn't get a very smooth shift. Either the clutch came out when you were at too low of an rpm and the tires were actually braking for a split second or you had the clutch in too long, the rpms went up too high and the tires spun for a split second. You can chirp the tires in 5th gear if you hold the clutch in, rev the engine to 6000 and drop the clutch...but that doesn't mean you had a good shift.

I ran 11.61 with Pilots. There is nothing wrong with them at this stage, once you get into low 12's you may want to get better 60' times and that requires stickier tires.

- No waterbox
- 3 second cleaning of tires (NO burnout), just spin them so that they are dustfree.
- Depending of the track, launch at 1800 rpm. Increase with 200RPM every time you feel you got close to no wheel spin. I launched eventually at 2200.
- Watch out 1st to 2nd, you may get nasty wheelhop.
- I experience no wheelhop with my -93 at while launching, but may get it on 2nd.
- Tire pressure at 22-23.
_ I lift the cluch nicely on 1st, while increasing the RPM if the car bites. I will be more brutal on all other gears.

I ran 12.2 and 115MPH without NOS
11.61 and 127 with NOS engaged after 1/8th mile.
My 60' times were 1.9...2.0

Good luck!

(Ps. What was the track altitude, that has a lot to do with numbers...)

Well being in vegas I will run 2 to 3 tenths slower cause of the altitude. I had the rear tire pressure at 30psi. My 60ft were like 2.1. I didnt rev it very high at the line but I did drop the clutch instead of just trying to roll the car out. I expect a 12.8 will be my best time stock out here.
