What do you guys think of my launches? 3090 Density Altitude (2200' elevation)
3700 + raceweight
Going through dual dual exhaust
6800 RPM Clutch Drop
15 psi
60': 1.646
330: 4.899
1/8: 7.580
MPH: 92.37
1/4: 11.820
MPH: 116.79
Time to open cutout and add a little fuel
16 psi
60': 1.767
330: 4.969
1/8: 7.616
MPH: 93.54
1/4: 11.797
MPH: 118.23
Track was going away at the end of the night. I think it has 11.6x in it with the cutout open and cutting a 1.6 60'. I couldn't believe it bogged the motor down to 4000 rpm on my 6800 rpm drop! These M&H 26x11.5-15 cheater slicks hook like a **** for being a slp lowered suspension car. I have the long torque arm from MWC and it's set in the 3rd hole from the bottom. Also stock LCA's set on the 2nd hole from the top. SLP Bilstein shocks / springs with UMI adjustable panhard rod. Airbag in passenger side 1st run was at 20 psi and all the other runs were at 30 psi. Pinion angle is set at -1.5 degrees. Slp sway bar is disconnected up front but I have not removed it. I need some skinnies too, my 17x9 ZR1's weigh 47lbs a piece.
What do you guys think?

Doesn't look or sound like it hooks at all. If you could stop it from spinnin so much just imagine your 60' times. Maybe i am crazy but that is what, I saw spin then go,

I do have a torque arm, it's a MWC long style chromoly torque arm mounted to a new transmission crossmember brace. 3rd hole from the bottom. All MWC fab 9" come with a torque arm. My buddy has some rear shocks he said I could borrow, comp engineering 3 way adjustable. Maybe I should throw those on?

Says 26x11.5-15 M&H cheater slick in the 1st post, they are a bias ply tire. Car came from the factory with SLP uplevel 2 suspension. SLP springs (1" lower) and SLP bilstein stock shocks 122,000 miles. Ya got beat by a trailed drag mustang, thats ok I drove my car to and from the track on it's own power.
Here is my 6800 dump, I know there is knock in this run but I took care of that next pass. Went from 6800 RPM down to 3944. Green is MPH so it spun than hooked and bogged on that pass. The pass I cut a 1.767 it spun for a while but never bogged, track went away.

hole place dosnt matter (how low is ther car in the back, tire siezs, whats the rake ect....),
whats the angle on them? use that
buy a nice angle gauge like the dig craftmen one.
get the sway off and get some shocks, get it to move some weight.

Well the problem is the 3rd hole is the lowest I can set it without hitting my exhaust 
Eric from MWC told me to set it at the 2nd hole but looks like I can't go that low. What points do you reference as to car height when measuring? I know they are 1" lower springs, actually I think they slp / eibach on them. With 30 psi in the airbag it really raises the rear, maybe 1-2". I can't set the stock LCA's any lower until I get some adjustable ones. I will have to take some measurements. Afco / Strange, how do they ride on the street? Mainly a street car but if I can adjust them to ride decent on the street that won't bother me. Do I need all 4 or will just rears or fronts work for now?

What gear are you doing your burn out in? I do mine in second, get them nice and warm. Might need to do a bit longer burn out. Im on Radials and getting your 60fts..and Im spinning a lot more than you.
Get a 2 step..makes things soo much easyer, you cant not tell exactly what RPM your leaving at and with a 2 step you pick what you want and all your job is to watch the tree and bang gears..
Shocks are a must if you want to go any faster. I say fronts before rears. Iv got QA1 "Rs" single adj. Upfront and Strange Singles in the rear. I was told Strange and Afco are the best, but my Strange Rears are a bitch to adjust, No instructions, no nothing when they come to you..Not that Im a retard and cant put shocks on but it makes it nice to know what way does what in the ****. Iv cut low 1.7s on radials(going to bias plys for next weekend). Front shocks can be bought for prob $500 with springs and rears $300 I think is what I gave. It all depends on how much more you want to spend. I leave my fronts full soft and the rears 3 from full stiff. Not too bad of a ride, no corning very fast(also have a spool) but the lady doesnt mind the ride. You cant have a comfortable race car man. It took me a long to to suck it up and take some comfortable features to go faster.. Im 21 and its hard for me to pay for school and a race car that I drive almost every day..save up and BUY SHOCKS!!

most likely not.... Im on a 15 lb flywheel, and cut low 1.4's.... So is barry from qtp( low 1.3's) and a few others... You also cant drop it at 5500 on one run, 6800 on the other and expect either to be spot on... I usually start around 62-6300 and go from there in 100 rpm increments. Some spin is required, so launch from a bog and increase rpm until you just start to spin for a couple revolutions.... Dont bog, and increase your launch rpm by 1300....

^ Thats why I suggested the 2 step for him. My dad and I get into that argument all the time about bogging/ hooking and minimal spin. Iv said I need at least a little spin than a Dead Hook Pull the tires and then the Rs drop to 3500..then watch the front crash down..
