launched around 6400rpm
26/11.50/15 hoosier qtp 15.5psi
qa1 fronts 275 spring set to 1
qa1 rears stock spring set to 8

wolfe drag bar...car was scaled on all 4 corners and wolfe was set for preload

side note...no screws in rims, and the tire is spinning about 2-3" on the rim each pass


please help me get into the mid 1.4s

i have 4.10s in the rear as well


thanks in advance

your going to need to screw the tire to the rims... if u 60 harder is only going to get worse

4.30 or 4.56 gear, It was hard to hear (had to listen/watch a couple times) to the video, sounds like either you're letting the clutch out slowly, or it's bogging (both being no good)

Also, powershift that car. I see the nose dropping at every shift...... shouldn't be.

You powershift it you will be puting a tranny in it in due time

not bogging, i could be a lil lazy on the clutch tho.

i also have a built trans but hesitant on power shifting

Do you have a 2-step? Looks like the car is rolling forward about 10 inches before the frontend picks up, indicating you're either letting the clutch out really slow, or your clutch isn't disengaging completely. Does your car roll thru the beams when you bring the rpm's up?

Depends on what you mean by power shifting. I don't lift when I shift but I still use the clutch. As long as your clutch disengages properly you won't hurt it.

no 2 step, and no it doesnt roll when the clutch is ingauged. im still trying to learn how to launch at these high rpms.

i used to go from 5-5500 w/ the DRs and slipping the clutch

ill try to come off the clutch harder tonite.

you NEED a 2 step. Doesnt matter if its the MSD or the Lingenfelter. Makes launching an M6 car sooo much easier. Set it up, pull up to the light, put your foot to the floor and GO!

You dont NEED a two step.... does it make it easier, yeah... Does not help his problem of not 60'ing hard.

IMO the video is hard to see whats going on, you need to be closer, daylight, side profile where you can see body separation, tire spin or not, bog, whatever. I do think your tire pressure is a bit high, and you might want to stiffen the front shocks a little bit. 2-3 perhaps. But you reallyu cant tell much at all from that video.

A 2 step would take all the guess work out of your launch RPM. Then you can tell if its too much or not enough. It looks like to me that its bogging and he isnt coming off the clutch fast enough.

SSPerformance

Actually with out a 2 step your really guessing on the launch... A 2step with a m6 car is a must its not going to solve your problem but it will help a lot dialing it in

Personally I would bead lock/screw in the tires and then go from there....... 2 steps help but not the answer for everything. I would get good with what you have first.

Untill you do the above try droping the clutch harder and power shift. I have done it many times no problems..... as long as your clutch is egaging then you are good with the built trans. Just need to push it in far enough for it to engage...... often it is like half of the clutch pedal travel.

Once you get the tires to stop spinning on the wheels it will be another learning curve.... If it was me I would work on everything past the 60 mark untill the tires get screwed.

I'd agree that you don't NEED a 2-step, but it will make dialing everything in a lot easier because it's much more consistent. Just one less thing that you have to guess at.

Putting screws in will need to be done. If you're slipping the tires now with nearly 16psi, you'll really be slipping them with a harder launch and maybe less psi in the tires.

Once you get the tires screwed down, I'd lower tire pressure and snap the clutch out harder. Let the tires take the hit, and let the rear shocks do their job. You may need to stiffen up the rear shocks to control body separation.

As mentioned before, if you can get some better video it would help also. Try to get a good 1/4 angle from the driver side rear so we can see the rear of the car and the driver side of the car at the same time.

ill try to get that angle tonite at the track

2 steps are great for consistancy but IMO not good for trying to get the best 60ft. I think by free reving it you'll leave harder then a 2 step. But free reving is much harder to keep consitant. Also pre-loading the drivetrain will yield a better 60'. At least in my experiements it did.

Spinning the tire on the rim can get pretty dangerous if the bead of the tire falls off the rim. Imagine that ride. Now go buy screws.

I disagree, to an extent. I never have a problem launching, I can hold it at 6500 rpm all day every day, without fluctuating, if I think I need a tick more, i'll hold it at 6700 rpm, etc.. To those who just want something repetitive with out worrying, it's one thing.

I do find it funny though, that most if not all the two step cars Ive seen in my old power range (430 rwhp), are less consistant, and didnt 60' as well as me. I was cutting 1.42-1.44 all day three 1.42's in a row. again that video is just isnt showing enough. Anybody else think that his car shouldnt be spinning the tires on the rim? Ive checked mine, they dont spin at all and I run only 11-12 lbs.

SSPerformance

I thought the same thing it should not be spining the tire on the rim... when i was a m6 car 5 years ago i was cuting 1.50 60s and not sping the tires on the rim

mine don't spin, been 1.43.

what flywheel do you have?
