Launching at the track What are you guys doing? I was trying to side step the clutch at 5100, but it seems i am doing way better with the best of a 1.9-2.0 60 side stepping(scared to go higher with stock DS), to 1.7 with slipping the clutch out rather aggressively.
You guys dumping the pedal or slipping it a bit and letting it roll out?
Wanna know about street cars that hit the track, track cars, you do your thing, this is a 90% street car.

The way I do mine is I let the clutch out to right before it will engage, rev up to 6k and simultaneously I dump while smashing the gas to the floor. 1.58 60ft is the best to this date. That way has been the most consistant also. I think the worst with this method was a 1.61 but it was hot as HELL that day. Also this is with a 9" and stronger driveshaft.

****, i am doing it all wrong, LOL.
Well, i am running a stock DS, so i am going to keep my method till i get a stronger unit, then, i will have to try you guys method, LOL.
What pinion angles you guys set up for? I am at -3* right now.

I ran a -4 at the track. I'd say your fine with -3 just have to play with it. I ran my best time and 60ft at -4 so I left mine set there for the track and -2.5 on the street

99.9% Street car with some Racey Parts. IMO this is one of the more Street Type Race cars that you will see.....

Due to race weight, you need to leave like a hero, flat out. Meaning it is time to main up to a good DS.
Since this post I have added Adj shocks all around, UMI Drag Bar, and Trans Relocation kit, a host of other things. JL-Ws6 still is trying to get me to gut the car, put on Carbon Fiber door skins and Kirkeys so beleive me there is more to go.....

Yea, i didnt have my lap top, i was in a hurry to get to the track and forgot it, i was going to go to 6000 and slip the clutch out hard, but not side step it since the stock DS is in there. I am supposed to have a local guy that makes them for 250$. So, hopefully that will be in some time after the 1st of the year(kid on the way in december holding funds back), then a set of ported 243s. Right now, i was happy with the 1.7 60 because i know it has room to grow.
Anyone use a Centerforce DFX clutch? Mine is doing very well and after i rebuilt the trans, i looked at the clutch disc and WOW, i have allot left for beating on it for a year, LOL.

Sorry for my ignorance, but what exactly involves 'side stepping'?
Also, when you say slipping the clutch, does that mean you have the cluth pedal so the clutch is only somewhat engaged, so it slips to prevent such a large amount of power to be transmitted? If I'm correct, how long would you say you slip the clutch before releasing? .1 seconds, .25 seconds? From the sounds of it, it takes practice. Lastly, wouldn't 'slipping' the clutch wear out the friction material more so than just quickly dumping the clutch? I'm guess it causes more clutch wear, but saves the drivetrain from a violant jolt?

I believe side stepping refers to having your right HEEL on the brake pedal, and you right TOE on the gas pedal. Control the clutch with your left foot like normal, just before letting the clutch full out, pick your launch RPM, release the clutch so you can juuuuuust feel it start to engage. Then when you see that last yellow....roll the throttle to the floor while simultaneously letting the clutch (slip it a bit) out the rest of the way and taking your right heel off the brake.

Slipping the clutch is controlling the amount of clutch you release and yes, it does prevent such a drive line shock like side stepping. It dies use a bit more clutch material i am sure, but nothing noticeable if you have any decent gear. A 2.73 gear and slipping it HARD to achieve the best 60 foot possible will use some clutch life because there is allot of friction trying to roll out. A deeper gear, 3.73, or even better 4.10 or more does not require you to slip much before 100% engagement, due to the car being able to roll out with the extra gearing.
Hope that helps.
Otherwise, heal toe is not the same.

Slipping the clutch if you can is best on the street, dumping it causes instant spin with any real power.
Here was my best pass last night, again slipping the clutch:
Here was my best pass last night, again slipping the clutch:
On my old mustang, I used to set the 2 step at 3000 and floor it. When i see the last light, I let go of the button and dump the clutch when i see the shift light.
That gave me 1.65 60' with a 300 whp motor and 1.50 with a 150 shot.
I will do the same with my camaro. I have a Strange 9" BTW.
