my car doesent hook worth **** on concrete even with a good burnout...idk if im doing something majorly wrong or what...its only 324 horse to the tire...full bolt on car with SS4000 and 3.73 gears

Bigs n Littles with 275/50/15 ET street radials
adjustable short arm set to -1.5
all heim joint lower control arms/pan hard bar with relocation brakets
Anti-roll bar
strang SA front and rear, 275lb springs in front

idk if its the tires...everytime i burnout or anything it seems like they just feather really bad...and maybe thats why it spins...maybe a water burnout ? usually people hook pretty good on this concrete where the races go down but i cant seem to figure it out

 

prep the road and launch in your burnout...a line lock will help here...

also for the street a slick is way more forgiving...a drag radial will not recover...

 

You can't hook w ET Streets!? Are they old?? Lower air pressure some

 

Go up a hole higher with the torque arm if you can it will make it bite harder off the line.

 

a hole higher will give it LESS pinion angle...and i gave it more pinion angle already and it hooked alot better...i just need to learn the right burnout so it doesent feather the tires i think

 

^ And this is the reason why you cant hook.

 

Surface temp and prep has big to do with "hooking". IF you could pre-prep, some PIMP Juice or even some VHT would do wonders. IF not able you can look at things like a 2 Step so you can limit your launch.

Automatics do not a great deal of driving skill but knowing the car helps and knowing how the car acts on the street, you can still do a great deal with foot breaking.

 

^ What he said

What tire pressure are you using?

 

The higher up the front of the torque arm goes on my car the harder it hooks and the higher the front tires lift. Just my experience.
May be that my MadMan geometry is a little different than your torque arm.

 

get 4wd

 

roll out a lil before u get in the throttle i do not do burnouts on the street and dead hook . just takes a little practice.how much pressure do you run in your tire?

 

I run my 275/60/15 M&H DR's at 17psi, no burnout, mash gas off idle and car dead hooks on the street. I just played with the pinion angle, tire pressure, and launch till I found what worked for my car.

 

Way too short of a gear/tire and a lot of converter is most of your problem...along with a probably poorly prepped or not prepped at all street

 

Go with taller tire like protree said ur tires are to short for the gears and stall that should fix ur problem u could do 70% vht and 30% alcohol I wouldn't do water cause the street ain't prep and mostly just for slicks cause Ull be spinning more with street tires

 

But try the vht with alcohol mixture first and heat them tires up and line back up on the line

 

That's allot of stall... Taller tire, or a Bias Ply tire.

Put the tq arm up as high as it'll go... usually there's only 2 holes, top one will bite harder.

LCA's should be level to the ground, ditch the Relocation brackets. Relocation brackets are great on the street, love them to increase handling, but they're ***** **** for making a car hook. Just a tad higher on the sub frame compared to the axle, almost flat is about right.

Pinion angle varies per car; on ZR1's with 315/35/17 mine is -1, on my 27" Hooser's it's -2.5 Don't get hung up on it.

Ditch your front sway bar if you haven't or just remove one of the links before racing.

I have a feeling you're stalling the car up, holding the brakes...

Leave off idle... if you're stalling the car up and you feel it transfer weight raising the *** end you're transferring weight to the front tires, which then has to transfer back to the rear tires.

BEST THING YOU CAN DO: Read the suspension posts by MAD MAN and keep trying different adjustments. I don't have a single product of his, but his suspension **** is spot ******* on, doesn't get any better.

 

I have the same major problem - can't hook at all (best is 1.83s 60') on 28x11.5 MT Slicks. On the vids when I bring the revs up while footbraking, the rear raises up considerably - is it bad?

 

This makes me imagine a see-saw. Kid A transfers the weight to Kid B, which then has to transfer it back to Kid A before the "launch".

You're saying take the torque arm out completely?

 

no he is saying leave the pinion angle at 0 or straight frm drive shaft to rear. i think.
