The best 60ft i'm yet to cut is a 1.50 which is pathetic with the power i'm making. that is leaving off the footbrake with no boost and not spinning.
My suspension mods are
Spoohn Adjustable TRQ Arm
Spoohn Adjustable Panhard Bar
Sphoohn Adjustable LCAs
QA1 series R front coil overs
BMR relocation brackets
3.50 gear
Strange 10 way adjustable shocks rear
rear springs cut 2 coils+ to lower the back after the 9"-----this is the only thing that makes sence as to why i cannot leave hard at all.
I'm using 28x10x15 hoosier full slicks running 10psi i tried all different tire pressure settings with no luck.
Everytime i try to leave on the T/b With any kind of boost it blows the tires off.
I've heard many people tell me all kinds of different things and i've tried them all at this point. Make my rear soft/hard, make my front soft/hard it does not matter i cant hook to save my life. My pinion angle is set to -2to -3

are you hooking from the initial first few feet or just spinning as soon as you let off the brake?

its very hard to say, i would think it hooks the inital foot or two sometimes and sometimes not, but most of the time looks like it just blow the tires right away.

Maybe the rear springs arent letting the weight transfer to the rear tires... Do you have a video perhaps?

What RPM does the car TB to?

Do you have a 2 step? if not invest in 1.

Do you leave straight or crooked. Aka are you doing lopsided wheelies?

i need to wire one up, my dfi has one built in
i can build as much as 20psi+ on the transbrake, usually dont pay attention to rpm but if i had to guess around 4000 is what it flashes to, i tried leaving at 5psi, 10psi and 15psi with same results

i'm not doing wheelies , the only way i can leave is off footbrake the car comes out pretty lazy and then 20-30 feet out, it starts haulin ***.

4,000 rpm with a 3.50 gear is alot of wheel speed when you let go of the button. The wheels are trying to go from 0 to 50-60mph instantly and if you have the power to not bog the motor it will just blow the tires away.

We had a similar problem with Shiz's car in memphis. It wouldnt leave off the Tbrake without spinning. We put the 2 step on it and dailed it back to 3,000 and it left with the wheels 3' in the air on the next pass.

Hook up your 2 step , set it at 3,000 to start and work your way up.

Yeah I was gonna say, that 3.50 gear is pretty high.

i footbrake my car with a 3.50 gear, no boost(Procharger). i started at 13 pounds in the 28x10.5 Mickey slicks and a lighter shock adjustment. i went 1.37's last weekend, and looking for 1.33-1.35 this weekend. it definetly sounds like your hitting it way hard for the setup. i may question the tire pressure, being low for a transbrake. maybe balling the tires up at the hit? you've got all the stuff on the car to make it work, you just gotta find the sweet spot for your combo. did you even get any still shots of the launches? pics would realy help.
