Can people post their average RPM launch and 60 ft times?

 

this would be interesting to see as well..especially advice from ceasar and nealoc...

 

unfortunately no one is caring, I'm just trying out how to launch better because I suck. I can't break 2.4's. I only have once. I try launching at 2500 rpms and I think that is a good rpm for me but I suck at modulating the clutch.

 

1200-1300 RPM. 60' anywhere from 2.28 to 2.15

 

ps: thats in my auto, not 6 speed

 

What type of wheels are you using?

 

Luanch technique: Spin 2-3 sec to clean tires. Slip @ 2200rpm ~70% throttle and clutch moving smoothly to 100% in about 1.5 sec.

Last 23 60's: 2.217, 2.205, 2.200, 2.174, 2.170, 2.208, 2.212, 2.181, 2.207, 2.199, 2.230, 2.223, 2.165, 2.245, 2.249, 2.162, 2.216, 2.231, 2.271, 2.261, 2.303, 2.253, 2.196, and 2.248.

AVG: 2.218

 

anyone else?

 

if you really want to know about launching techniques I suggest you just pm ceasar or nealoc or something...

 

I feel this question is a little bit on the broad side. I do a dry burnout first for a second or two to remove all the derbis off the tires. But the way i launch, I brake torque at 1400, as soon as I feel the car grip...then I press the gas pedel all the way down. I usually pull a 2.250 to 2.3 60's on street tires. The reason I said this is kinda a broad is because the tires you have on, the tire pressure, rim and tire size, if you are lowered and have adjustable struts/shocks the settings of that, can make a difference in the way you launch. Everyone launches differently, just keep practicing you'll figure out what is the best way to launch with your current settings. Good luck

 

I dropped the clutch at 2500 and I had a terrible 60 ft last night of 2.7... Ran a 15.9 @ 92 mph

BTW: this was my first time ever to race a 5spd.

 

As for tire pressure I'm just assuming that those with street tires would be using 25PSI in the front tires. I have read tons on launching. I have been launching at 2500 rpms and getting 2.4 60', one time I got a 2.3. Anyhow
I'm just trying to see if the majority launch at higher rpms like around 3000 or if they launch close to where I launch.

 

I've found that pwr braking just causing my tires to spin. Although the last time I went racing I had zero traction (78degrees, 95% humidity 1200ft elevation) I ran
10) 15.1@91mph and 1) 15.8@86mph (spinning) my best 60ft was 2.2 I think. And I tried various launching techniques but the humidity really kills my car. (03 SE auto).
btw no one was at the track that night either I got those 11 runs in in less than 2hrs AND I sat around awhile between runs to let my car cool.
