For the street 5k to 6k is alright but at the track i would say 6k or above i usually launch at 5500 on the street and 6500 at the track. All i have is an act hdss clutch all the other drive line parts are stock and i havent had any problems *knock on wood* theres no reason to even have it set that low theres no point

Theres also no need to slip a clutch when launching and i dont mean just dump the clutch either

 

Well whats most important to me is the clutch rather than performing the best launch. I know the best thing is not to launch but I'm just trying to find a medium point of launching and wear.

The way I saw it was lower rpm's = less of a bad friction on the clutch and the higher the rpm = more friction. But apparently you guys are telling me lower rpms will cause more wear because it would require an extended slip of the clutch.

 

Yes, due to more friction. I don't know why you thought lower rpm would mean less friction. There's no power that low to get the car moving, thus requiring a long burning destruction of the clutch.

 

Well i thought less friction because lower rpms = slower rotations and vise versa for higher rpms. Pretty much like rubbing your hand on the carpet slowly vs rubbing your hand on the carp quickly. But I understand what you guys are saying about lower rpms requiring long slipping of the clutch = bad.

Just for the record, I only slipped the clutch a tad bit, like no more than a second. That is why 3k rpms launch caused the car to bog and the 4.3k rpm launch was successful but not as quick as I'd like it to be. If I had to time it I'd say the slip lasted no more than a second and I only launched 4-5 times max that night.
