depending on the surface im on i launch anywhere between 4500 and 7000. usually closer to 5500 tho. tires will spin, but it doesnt sit there spinnign, it lunches off the line as its spinning.

Dumping the clutch at 5,500 rpm's is not for a good launch, that's if you want to do a nice burn-out.

i'm sure if you go any lower, you'll bog, unless you slip the clutch a bit...and if you go any higher than 5500 rpm, you will spin the tires more.

 

works great for a launch for me. as a matter of fact. if it's a sticky road i need to up it a bit or i bog.....that, will kill a differential.

 

yup, it is the clutch delay valve, really ez to remove

 

If you want wheelspin in your AP2, or a mediocre to moderately good launch (I am no expert at drag racing, but I can at least get wheelspin on demand), do the following:

Rev to 5.5-6k, sidestep the clutch, don't let it out slowly, sidestep it. By this, I mean, have just the edge of your foot on the clutch, and quickly move your foot out of the way (off to the side) of the clutch so it slams upwards. The CDV will let the clutch take a little of the driveline shock, and then after that your clutch will catch and you'll have as much wheelspin as your heart desires.

 

Well, it helps Honda though! Honda probably doesn't need replace your clutch when its worn, but probably need to replace your diff from warranty if you know how to bend around the rules a little bit

 

good point
