As many rpms as they and/or your clutch will hold. If its 4500 rpm for instance bring the rpms to there
and go full throttle just as you sidestep the clutch. Just keep raising the rpm if you are bogging.
Im not sure the stock clutch will hold on a 5500 rpm drop.

Whatever you do, make sure you get the radials, and not the tube type on the street. You get caught in the rain or anything with bias-ply ET Streets, you might as well pull over, and call a cab.

RE: launching on drag radials
launchin on drag radials still takes some skill.... Yes they do hook alot better than normal street tires but its not just a dump the clutch and go type of deal. Well at least not in the cars that i have driven. You still have to do some clutch slipping and throttle feathering. Just try different rpm laucnhes, and try as many different clutch/throttle movments as possible to see what works the best. For me i have found that its best to hold rpms above 5k, let the clutch out somewhere between fast and slow, and hold the throttle in the same possition till it dead hooks then floor it.. and yes i still do get some wheel spin but the car comes out harder with minor wheel spin than it does bogging.

It really depends on the DRs and the size..... MTs in a 17" will hook better than a Nitto 18" the new MT in a 17 will hook with a 5000 rpm drop in a 450whp stang running 410s..... I've seen it!

DR's should hold a 1.4 on a 10 second car if the track crew did their job. Assuming you are not talking Nittos.
