First time at the strip!

[InspectorGAGT]

I hit up the strip for the first time tonight...got four runs in, 15.58, 15.61, 15.62, and a best of 15.56...however, my 60 foot times were always between 2.3 and 2.4 seconds...any tips on how to bring those down? Rest of the slips can be seen on my n-body profile (please don't laugh at the R/Ts, I've never driven a car on the track before!!) lol

Dude, good times for just a CAI. The R/Ts and 60's will come with practice.

Good runs man! Damn good considering you just have a CAI! Your r/t's weren't that bad, I've had worse.

To bring down the 60' times, I'd suggest lowering the psi in your tires to around 18psi (when you get to the track). Then, when you launch, turn traction control off, make sure everything's off, put shifter in "3".

At the tree, hold the brake down with your left foot, press down the gas with your right foot til the rpm's reside 2000 (you can try different launch points out depending on traction that night). When the last yellow light hits, let go of the brake, and moderately advance til you're floored. You should launch really hard, get those 60' times down.

I had 2.2 60' times, while spraying, with bald tires, and no traction. Just need to get the launch down tight.

Lowering your tire pressure on radials decreases the actual surface area of contact patch. Basically, you let air out of a radial and you ride on the side of the tread. Which means you will spin easier and wear out the side treads faster than the rest of the tire. Do a few small burn outs or you can use white paper to see what pressure gives you the largest contact patch area. Running less tire pressure helps with bias ply tires, not radials.

R/T has nothing to do with your ET or 60' time. It just matters when you are actually running someone.

How I launch (with ETS off) is to give a little gas and hit the breaks. Then let off the breaks and get back on them quick (kind of as if you were pumping them) and keep your foot on the break until you launch.

You should feel your chassis lift a bit. This is called preloading your chassis. Basically, your chassis will be set for the launch. If you don't do this before you launch, your engine will have to move the chassis like this after the launch. Which = wasted motion and power that your engine could be putting towards acceleration.

have you guys tried not break torquing, and just having your foot on the break, and just slamming the gas when the light goes green? kinda like at a stop light? cuz ive tried break torquing when im racing on the streets and track, and my reaction sucks arse!

Yeah, I know R/T doesn't really have anything to do with the run, but still, it's a little embarassing when my BEST R/T was a .718! :p

Anyway, about your launch technique...do you do this once you've staged? If so, how are you not moving enough so as to not make either the pre-stage or stage light turn off?

I've had about 25 runs now.....and the ones with the lower tire pressure always have a better 60' time...... so maybe you're right in theory, but at least in application lowering the tire pressure helps me out every time.

Ya I do it once staged, stage shallow or pump really quick (which is what I do). You don't even have to let to pedal all the way off. It doesn't take much to get your chassis lifted.

As for the tire pressure, I've been racing for 15 years. The only gains I've seen by dropping pressure was with bias ply. Step up to some stickier tires and you'll see even better results. Read the mags like Car Craft, Hot Rod, etc and they'll say the same thing I did. Just like "heating" regular radials is worthless. Just drive around the bleach box spin a little to get them clean and your good to go.

I've run my BEST times with the stock tire pressure.


I believe you greed4Speed...just like how over inflating would cause less traction. There is a recomended tire pressure on each tire for a reason IMO. But lowering it a little will help.....it's just when you lower it too much where it actually hurts.

Actually .7 R/T's isn't bad at all. I'm working on getting consecutively under .7, and its tough. My best 60' stock was 2.256.
