Bad 60' times :( what am i doing wrong? videos

hey everyone. just curious on some of the techniques you guys are using to get some good 60' times. so far ive been getting on average between 2.3-2.7 60' which IMO is keeping me in the low 13's. my best ET was 13.24 @ 112mph. I cant seem to nail down a good 60'. ive tried launch control, turning off all driving aids even drag radials. My mods so far are CAI, adm scoop, JBA short headers, JBA high flow cats, x-pipe, muffler delete and an ACT dual disc clutch and light weight flywheel. LS3 with stock tune dynoed at 414 whp, 403trq. My traps are pretty good averaging from 111-113. I have vids if that will help any.

the wheel hop is from dumping it at to high rpm, the bog is to low rpm, try 2700 rpm let it spin, as soon as the spin starts to let off...step smartly on the gas pedal. put your left hand on the wheel (i perfer 8:00) and keep it there, keep your right hand onthe gear shifter and keep it there. Your useing different tires and they all bite different... nto5r's need lots of heet. do a second gear burn-out and get some smoke rolling. nittos on these heavy cars like 18-19psi... good luck I'm sure you'll get lots of responces and everthing i said will be wrong... so use your best judgement.

looks like your having fun, i always like catching and passing other cars, your hooked and you will be at the track more and more... talk to other guys running sticks and ask them... as long as you don't sound ****y or like an ahole most other racers are willing to help you out. I just had a 60 year old women giving me advice last weekend... and she knew what she was talking about!

thanks for the reply so far the NITTO's im running are the NT05 non DR's so i wasnt sure of letting out air on those was a good idea being they are more for road course. I read the 60' time thread and i dont know how some of those guys are getting great 60's with the stock pirelli's. I was hoping using launch control would shave off a decent amount time but didnt look like it. so far i have 13 time slips and im pretty consistent in my times. Id like to hit high 12's. My trap so far suggest its possible maybe?

guys are dropping the pirelli's down to 18-24psi , try 18-19psi in the nittos after you run check the tires with your hands and if the center feels hotter then the shoulders let more air out, if the shoulders are hotter than the centers add more air. (Lazer thermometers work great) since they are not dr's you may have to smoke them a littlle more. your burn outs should be sitting still, not rolling, and keep your rpms up and steady, go till you see good smoke, than if it sticks increasse your rpms on the next one, if it spins to much lower your rpms.... does your dad know your running his car on friday nights? LOL

Kind of an odd attempt at humor... seems like some sound advice on the topic though, might be worth a shot.

Where to begin?

First off, I completely disagree with dropping your tire pressure as low as has been suggested. Pirrelli's are a street tire and are made to work best at a certain psi and temp. Taking too much air out will cause the tire to cup and make traction even worse. My 1.77 60' time was on stock Pirelli's at 32 lbs, with a very small burnout(no smoke).

Secondly, I didn't see any mention about how long you have been drag racing or how many passes you have. Most of the people on the 60' list have a lot of seat time and have made a bunch of passes. It takes time to learn how to properly launch a M6. Like stated in a previous post, check out the rangeracceleration site, it has a bunch of good videos. Find what works best for you and fine tune it.

Thirdly, it may not be just you. Track prep plays a huge factor in a good 60' time. Find another car at the track that is similar to your setup and see what they're getting. If they are cutting sub 2.0 60' times, then you should be able to do the same. If the track is crap, It'll be crap for everyone.

With good air, good track prep and a good launch, your car should run well into the 12's. It just takes a lot of practice. A LOT.

Here is what I try to do and it has been pretty successful for me.

1) clutch in
2) feed throttle to desired launch rpm (actual rpm varies based on track, power, tires, trial/error etc.)
3) I release the clutch quickly, I don't side step or feather it
4) I hold that same throttle position until I feel the tires grab. Then and only then do I add more throttle. Even then I don't stomp on the throttle.

A lot of people in their excitment will hammer the throttle at launch, and this will often only add to the traction problems. It takes some muscle discipline to hold the throttle and only go WOT only after the tires are hooked.

I've found it is better to maintain 3/4 throttle with traction, than WOT and spin.

I'm thinking it may be this. My A6 ought to do most of my launching for me, and my 60 is still crap. Charles has bit of experience and plenty of power, and still not turning good numbers...

And Ryan- your pass against Taylor at Firebird is still your standing best, correct?
