yup thanks, also its scary and new when you are hitting 124mph in such a short distance. i'll probably poop myself when i decided on a 4.11 gear.

Congrats on getting the car back out and on the track. Nice post on "the other site". :D It sounds like you need more air gap in the clutch to keep it from creeping through the beams. I have always heard you want to run more air pressure in a drag radial than a typical slick, it may be why the car feels squirrely on the high end. Does the car leave straight? How's the front end alignment? Leaving hard is always a balance between clutch slippage and wheel spin with a manual trans drag car. If you dead hook the tire you'll pull the motor down too far, if the clutch grabs too hard you could spin the tires too much. Are you running an adjustable pressure plate?

i'm now at the point where i have to run tubes in my slicks. i need to run lower pressure to hook good but i get squirely. i'm going to get some tubes and try to adjust this clutch.

 

i don't think my pressure plates are adjustable but i'm going to try to adjust the cable even more.

Sounds like your dialing it in...good luck on ford vs chevy night

 

i'm in between just buying tubes for my current tires or getting a little bit wider slick with the applicable tube.

i should have the new dizzy here sometime next week and that should cure the idle issue and after my burnout idling issue. we are aiming for 14-16i timing and 28 tot timing.

 

i got the clutch adjusted more and i'm getting full'ish disengagement. at the track it was going thru its break in period so it started not fully disengaging. now its all tightened up and making sure i ain't preloading the TB much if at all,

 

i am selling the 28x10.5-15 stiff slicks and bought some 28x10.5w-15 slicks thats 1.4 inch total section width wider and 1 inch wider in thread and not to mention even stiffer sidewalls and different compound of material. and i'm going to run tubes to strengthen the side walls more and not feel swirly on the big end. those side to side movement is scary.

 

with that, i'm going to keep putting the wheels up and launch this thing at 4k at the christmas tree. i did find that "DEEP STAGING" IS working best for me. i can stab down a .009 - .041 reaction time when i deep stage instead of my regular non deep staging and get a .090 reaction time.

it takes alot of seat time in the car. i must of taken at least 100 passes in the mustang now and i'm still learning the car. i have found that i do the BEST when i deep stage when most others do better when they swallow stage.
