well i drive a OZ but its the same physics and it seems to work good for me...

Rev to just under 2000RMP feather the clutch out, when the clutch is almost disingaged i start getting on the gas...no under power and no squeeling tires. nice smooth quick (for a 120hp car) launch

FF cant be launched without drag racing tires and a good setup.

Its just the laws pf physics.

(I guess you could launch it into reverse, then physics would actually be on your side)

Hey Guack007 where do you live? (I have a White ev0 8 [same year])?

Anyhow, what would be the best possible way to launch at a safe (lower) rpm but still have the desired effect?

I want to drag a few of my friends (to get respect from those damn domestic lovers), but I don't have confidence to drop it at ~5500 rpm.

IF done right the clutch grabs perfectly at 4,000ish sometimes a hundered or two lower. With this methood I get no clutch burn (unless I slip the clutch to long) and Get an amazing tire chirping launch.
With my current setup and tune I found this works great with my 313 High torque numbers.
I completely agree with this and plan to run the same mods you have except Ill use a MBC and Tanabe DP. Go Dynoflash, Nice torque numbers brother.I am also going for custom CAI which should help hp out.

I live in south orange county, you?

Ever hear of Lake County? Actually I asked that because There are about 3 red Evo's in town [all purchased after I got mine, so I feel special ].

Just wondering if you lived near me, that's all.

I've quick slipped on 5k and 6k... Smell the BURN~!

I saw Rryan's car (boost solution) last weekend. Sick. Did a 7k RPM Drop, 4 wheel spin and a car length jump. I've never seen anything like that before.

He's got a single disc clutch tho.

Anyone dropped at 7kRPM on their stock clutch?

Dropped?! Slipping might work...but thats like 1% without damaging ur clutch. Droppin it would 100% DESTROY ur clutch. Dun think anyone is that dumb to kill their own clutch rit?

I rev to just over 4k and let it out quick but not drop it hooks up pretty well for me that way.

Isn't dropping the clutch meant to transfer all the power to the wheels in the form of wheel spin? If so, dropping the clutch on a stock car would be better than feathering it. The longer it takes for you to let the clutch out by feathering, the more wear you get on the clutch. Therefore, dropping it will allow the clutch to grab instantly (unless your clutch is defective to begin with), and only wearing the tires as they spin. You want that tire spin to occur to transfer all that power, otherwise, you'll just shock the transmission pretty badly (aka bogging). I don't launch my car, but logistically, what do you guys think about this method:

rev to 3k
as it comes time to launch, mash the gas
when it hits 5k, drop the clutch

That way, you get the full turbo spool up, since you're at full throttle, and therefore, peak power, when you drop the clutch. Merely holding it at 5k rpm, you won't have any boost when you drop the clutch, that's why you gotta drop it while you mash the gas.

Just curious...how many of you have the SS line and the restrictor removed? Does that help anything when it comes to lauching from your experience?? (i.e less burnt clutch smell??)

5800 rpm's quick slip.

front tires spin first then the rears will take you off...1.73 60 ft. on my old A046

Can't seem to find that sweet spot on my new AVS ES 100's. 1.9-2.2 60ft's suxxx. Bah I'll give it time to break in.

30+ drops on stock clutch with my setup,20,000 miles and clutch is still hanging.Wheelspin is good,that means less shock to the drivetrain if it bogs.

I have tried dropping the clutch at 7k rpms about 4 to 6 times...it takes off without bogging but i got a 13.7 and 13.9 time in a quater mile (used my HKS Type 1 TT) I hit 13.51 when i slipped the clutch at i think 4k or 5k rpms...i think i would have hit 13.3 or 13.4 but my shift to second gear was a bit slow...i was scared becuz i always misshift second...haha so i think slipping the clutch will get you faster times...i only have the injen intake upper ic pipe kit and boosting 24 psi with the Turbo XS Dual Stage MBC. Stock clutch still and i have 20.8k miles...I know my car is slow...but im going show before go...then maybe sound...then go...all the cars with systems in Utah are making me sick to the stomach cuz they are so weak....But im thinking that the Injen Intake and Upper IC isnt giving me much HP so i was thinking about AEM Short Ram and the Bushur One piece Upper IC pipe...which intake Upper IC pipe set up do you guys think is better?
