    How to get the best launch/ET's

    Well, Ill just have to swallow my pride and say I'm a crappy driver. I went to the drag strip this past weekend for the first time and expected to at least run somwhere in the 12's. Best time was a 13.5 @113. Fastest 60ft was about 2.45 and slowest being around 2.7. Ironically, my traps got better even with those launches. I have many questions since Im a newbie at this. I do know about dropping the tire pressure down to about 26 on PS2s and I completely ignored that. How much of a difference would it make on traction? I played around with TCS and suspension. Whats the best setup? First time I left it on and the car kept cutting off power so I turned it off for the second run and played with the throttle. If I didnt spin, I bogged the launch. I believe I was launching at 3k RPMs but not too sure. I know the car is capable of much better times but I need some advice. I searched but no one really touches the subject head on. Just a note....The air temperature was a cold 40 degrees without windchill. It even snowed on the track (and dried) in between runs. Ill post the slips when I get home. I plan on trying again on sunday since its going to be high 50's to low 60's.

    Re: How to get the best launch/ET's

    Plenty of threads on this, but your primary issue is that the PS2s won't hook up with air temps as cold as you were in (40 degrees, wow!). The PS2s have a hard enough time hooking up with warm air temps, I can't imagine them hooking up when they are hockey pucks at 40 degrees. Also, the track prep could not have been good if it snowed.

    I think you'll do better by default if you go when it's warmer.

    PS I'm a noob, too. I'm planning on heading to one of our local dragstrips soon myself to better my sucky 12.7 time from last fall.

    I hear you brotha. Im not even too sure if I should go out with 50-60 degree temperatures. I heard hear say that you can actually warm the tires with a quick burnout but nothing major. Does this work for street tires (PS2s)? But you are right, my problems were mainly traction. BTW, I drive a manual.

    Re: How to get the best launch/ET's

    Definitely agree with anonfrank on air temps around 40 and the PS2's, but not his comment about how they work in warmer temps.

    IMO for a street tire they work very well in warm air on a decent dragstrip. It's going to be alot trickier for you since you're driving a stick and don't have the advantage of the tq. converter softening the hit to the tires, but I think in good weather you should see sub 2.0 60 fts. with some practice. There's one or two guys here with manual transmissions that have had success at the track on the PS2's, you might want to try and find their posts.

    Re: How to get the best launch/ET's

    I went out with temperatures about 40 and had the same problem. Tires won't stick when it's cold. My best run was when I started in normal drive (2nd gear) at idle. I still got some spin but not as bad. A friend of mine said that your ET will drop double what you can get on your 60' time. In other words, for every second off 60' you get 2 secs off ET. I'm going out again now that its warmer. Have to buy a helmet though.

    I believe you posted a thread on the no lift shift. You have a manual, yes?
    http://www.cadillacforums.com/forums...ift-shift.html

    Hows that working for you? I don't have a manual but I do have the PS2's and my best runs were around 55deg F with a 15mph headwind. Let the temperature warm up a little. My motor loves fresh cool air. I also did a small burnout just to warm the tires up a bit. Sounds like you are on the right track, literally.

    Re: How to get the best launch/ET's

    Yep yep that was me. Well, I haven't tried that technique at the track yet. If I cant even hold traction granny shifting then there's absolutely no way Id be able to using the no lift technique. I lost traction going into third that made me pucker. I went sideways so I had to let off. It should be around 60 degrees this Sunday so Ill give it a try. Practice practice.

    Thats the downfall. Anything below 70 the tires get harder and the car runs stronger = lots o' spinning.

    Re: How to get the best launch/ET's

    Well, Since its going to be close to 20 degrees warmer then Ill give it a shot. If not, Ill just wait until it get in the 80s. I debated getting the right drag radial set up for the job but I don't want to break anything with bad launches.

    Re: How to get the best launch/ET's

    Now that I think of it in the 1/4 mile your last gear at the line would be 3rd? So I guess the no-lift-shift wouldn't make much of a difference. I can't imagine a manual. Hard enough with auto. Good luck.

    Try not launching at such a high rpm. Launch it off idle like you would on the street and roll into the throttle. That has worked the very best for me. You should be able to net a 1.9x 60' going that route. Also, it is pointless to warm the street tires up. A quick spin will knock off any debris.

    ditto - if i try and launch at 3k with my stick i just get a bunch of wheel hop and end off letting off the throttle until it hooks.

    one thing i am going to try and do is launch out of second on the street. i think if i can avoid bogging it should work better.

    just to add some perspective, the cars rear tires aren't anywhere close to as meaty as a vettes. the lack of tire width alone is a killer when you have a car that has over 550hp.
