Manual Transmission - launching on DR's

im going to the track tonight for the first time wiht the new gears and DR's and wonder what kinda rpm i should be looking to launch at??

they are 275/40/17 Nitto 555r extreme drags. right now they are at 30psi but ill be letting air out also

any helps would be great i dont wanna waste a run or to trying to figure out a good spot

I've personally never had much luck with the Nittos but on my MT drag radials I leave about 3200 rpms on the trans brake and its cutting 1.4x's 60' on the engine alone .

Are yours 17's and what tire psi at the track ?

I use to launch at around 3,200-3,500 but the car would just bog but, now I launch between 4,000-4,500 on my MT 315/35/17s at 20psi and dead hook and go. I have a 9" though so be careful if you still have the stock rear. As long as your clutch and rearend hold up you should be fine.

No they are 275-60-15's on a 10" wide wheel . I have them at 14 psi .
