Big embarassing traction issues, need help!
It's probably at full weight or a bit more with SFC's and stuff.
My blower is heavy I know.
If so that's gotta go. Stock piece just flexes and gives away any chance of transferring weight to the rear tires. I watched your vid, no weight transfer whatsoever.
What's gonna lift the front end if your major connection from the rear end to the front of the car is made of cardboard?
Loose front shocks and a good torque arm is what I think you need right now. I'd like to see a 15" tire back there but since that's not your thing you should start with the other stuff first.
I also was looking at my control arms last night, I put a level on them, fairly steep downward angle. Is that angle partly responsible for me hitting the tires so hard and just losing weight transfer? With the rim and tire combo I have, I don't think I need to be hitting them so hard.
Yes you can get a better 60ft with the wheels and tires you have. Take the blower off. You arent going to dead hook 500+rwtq on a drag radial with no sidewall. I understand other guys have done it although ive never seen it. But those guys have their cars and you have yours, no two cars are alike, the make different power, have different suspension, different drivers, different weight ect.
I know you probably are tired of hearing guys telling you that you need more sidewall but its the truth, it will improve your 60fts.
Do you have any vids of your burnout?
You never mentioned if you leave the front swaybar on? I went from a 1.9-2.0 60ft. to a 1.7 60ft by removing the front sway and burning out in second, and im still getting my suspension dialed in.

My burnouts are good, I heat them up per Mickey Thompsons instructions. Never removed the front sway bar, I might try that. I've been doing 2nd gear burnouts all along

That front swaybar is a huge part of your problem. When you launch it is trying to lift your front tires but wont let the body lift off the front tires and transfer the weight, after hearing that Id say put an adjustable TA, take your front sway off, check your pinion and lca angle and you will probably cut some 1.6s pretty easily.
My setup isn't going to cut awesome 60 foots I know, I'm just trying to optimize what I have currently. I would be pretty stoked with a 1.75.

Iknow its easy to just say do this do that and buy this and buy that but with your setup and power its not going to be that easy.
But i really think you can get the car a better 60 if you slip it harder out of the hole and try working on shifting faster cuz that is holding you back some as well and have you found were it likes to be shifted at????
All the advice and tips are great.
shocks and springs baby! strange adjutables, with 300 lb springs. make sure the coil overs are cranked up, you dont want the car to have to work to raise the nose. you want it to pop up.
Dude, I'm not over 500 RWHP without the blower.
11 second passes aren't so simple when you're at 6800 DA either. Why don't you come to Colorado and give it a shot?
Best time before the blower, full bolt-on, 13.7
With blower 12.4
I'm confident I could hit 11's with some suspension tuning even at this crazy altitude.
Took a little trip after adjusting the LCA's to the middle hole, car seemed to push harder on the street but we'll see at the track.
I'm thinking about some 300 lb. springs to go with this coil-over setup.
UMI told me today that some 300lb.ers and their adjustable torque arm set up properly would give me a totally different car as far as launch is concerned.
FWIW also, you can't change shocks on a ground control coil-over setup without having to change the sleeves on the fronts, the setups are made based upon the shock you are running. I'm not sure I'm ready to go to some different shocks at this time so I'm kind of stuck with this right now. I should be able to swap the 440#er's with 300#er's.
I will continue to build my suspension and dial it in one piece at a time. If I can get this to hook on 18's and run 1.7 in the 60' with this setup, then just imagine when I finally pop for some slicks and runners on 15"s and some 3.73's or 4.10's in an S60!
Tweaking what I have, making minor adjustments and testing them are going to give me slower results, but I'm going to learn how to launch this thing and set it up and become better overall and learn about this car.
Thanks for all the help guys, you all are pretty much saying the same thing. I'll keep you guys updated.
