Ok, I'm at a point that 'm sure most have you have been at. I have been tweaking and adjusting the shit out of my set up to try and get a 10 second slip...but I cant get this car to 60 foot worth a damn.

I think I need to wipe the slate and start from a basic set up and go from there. What I need is input from you guys as to where I should set everything to start from.

My set up.

D1SC at 20 PSI 650 RWHP 550 RWTQ
T56 magnum
Mcleod RST
28x10.5 M/T slicks (I've tried from 11 PSI up to 15 PSI)
4:10s
BMR ADJ upper
BMR solid Lowers
BMR relos (middle hole)
BMR ADJ Panhard with panhard support bracket
QA1 Double adjustable shocks set to 3compression and 9 to 12 rebound
Strange 12 way struts up front set to full loose.
MSD 2 step

2step is set to 3500 RPM. I do 2nd gear burnout with line lock. Get up on the 2 step about half throttle and roll into it quick when I leave.

these were from last night. 12 PSI in the tires.

The 119 mph pass I lifted in hopes I wouldn't break 11.5....didn't work, but I never got kicked off the track so made the other runs.



My MPH is there, I just need to get this thing out of the hole better.

It feels good leaving, but at some point either before the 1st to 2nd shift, or at it, the car bogs or nose dives a bit...im sure this is where my problem is.

Any and all input will help me out here. Like I said I think I need to just start over and reset and go from there, so where should I set everything to start?

Video from last night, sorry its so far away, really cant see much of the start.

If it were me I would start by gong wot at the line instead of half throttle ached build boost. If that doesn't work, raise the two step until you spin.

On my tokicos I sweet them full hard in the rear and put 16 psi in the tires. On a good track prep I'll 60' 1.49-1.55.

I was launching my Bullitt at 5k without spinning. You need to talk with Kelly at BMR and go over your suspension settings with him. I also had the same bog at launch, never could launch hard enough to overcome it. I can't remember but I think my best 60' was 1.56 or something, typically in the 1.65 range. The first gear in the T56 is really tall so you need the high rpm and slip the clutch a little at the launch.

Thank you sir. I'll hit Kelly up.

Remember what pressure you had in your tires?

Were they 28 inch on 15s?

That sucks...Sounds like someone with experience with your combo might chime in.

Or you could just say screw it and throw in a 4r70!

I was running 26" Hoosier QTP. I wanted to run a 28" but I had 3.73 gears. If I had swapped to 4.10 gears then I would have been able to run a 28" tire. I ran about 19-20 lbs, any less and they would get sloppy at the top end.
