Most have said that they launch their ITR's at about 5k-6k and they start off not completely flooring it, and then work their way to full throttle....

what i have to say is this:

last year, my friend mike let me take his ITR for a run at the track, and he gave my GSR a run in return. I ran his ITR the same way i run my GSR, which was this.... i dropped the clutch at about 3k and kept the gas floored the entire time. shifted at 8200 or so each time. Ran a 14.3. His car is 100% stock, and the air in the tires were at about 20 psi. His best run for the night was a 14.6 and he was doing the typical 5500 rpm launch with a 75% gas applied and then flooring it. Just figured id let everyone know. He ran a 15.2 in my GSR (not stock) and i ran a 14.7

 

Most people recommend the first scenario as a starting point so people can figure out what works and what doesn't.

Your technique sounds pretty good and should give others an option to try if they are new to drag racing.

 

I'll try that and give it a shot, but with turbo 3k is where my turbo kicks in. So I wonder if there will be a lot of wheel spin? :twisted:

 

all motor I launched at 7500 on street tires and turbo I launch at 5500

 

launch at 3k...just drop the clutch! not slowly, drop it!

if i do it much higher than 3500, wheel spin!

 

thats why you dont drop the clutch, 3,000 is no where near the power band.

5,500 rpms, slip the clutch, dont floor the gas pedal until you gain traction, and say hello to 2.1 60fts. :wink:

anything higher than 5,500 and you're just wasting clutch

 

I pulled low 2.1 60's at 7500 rpm launchs on street tires at normal presure. also I trapped 2mph faster than when I launched at 5500
