Re: power needed to lift front end

Not so much power as it is suspension and traction. My cousin gets his left front tire about 2 inches off the ground in a 4200lb Caprice that put down 254rwhp - but he has QA1's all the way around - this was on a 1.7 or 1.8 60' too.

Re: power needed to lift front end

Exactly, I was pulling the tire on a very very mild 355 and stock suspension. so baed of that I would say it's possbile to have 350 hp at the crank and as long as the rest of the stuff is good to go, it's possbile.

The cars you see doing huge wheel stands (outlaws) can just as easily change a few bars on the suspension and leave like a pro stock.

Re: power needed to lift front end

i dont want to see clouds. i just think it would be cool if i could get the front tires 2-4 inches off the ground. But it is still going to be a street car.

Suspenion mods are going in as follows:

Hotchis STB, Panhard bar, Torsen bars. (k member - havent desideed on.
Eibach pro kit springs. bilstein II shocks.

gonna have plenty of powe - 500-600 RWHP after the build up

can i get the front up with drag-radials, or do i need a set of slicks.
skinnies up front.

Stock weight car.

The Caprice pulled the wheel with 5" fronts (skinnies for that big of a car) and BFG Drag Radials.

I hit 1.61 60's @ 3475lbs with me in it but can't even "pop" the front.

Re: power needed to lift front end

"pop" = get the wheels off?

also, do you have a 12 bolt or 9" rear?

QA1s make the perfect street/Track set up. All bolt on stock cam/Iron heads
and it only put down 260/307 at the Dyno.

Re: power needed to lift front end

Thank you. I wanted something a little different and I got it. New set up this year, 355 with Lloyd Elliot heads and Bretts cam. Should see low 12s or better this year and the car is still over 4,000 pounds. I also own a 68 SS Chevelle but that does'nt see the track anymore.

Re: power needed to lift front end

im pretty sure that after my build up (procharger/NX 75 shot/other goodies) and with some drag radials, ill have no problems getting the front up.

Re: power needed to lift front end

Not to sound the optimist, but I'd be willing to bet any affordable amount with the engine upgrade you have planned and planned pwr, there is NO WAY your going to stick that consistantly if at all on a set of stock sized DR's unless your running a multi step timing ramp to retard the heck out of it like the big boyz do.

You wanna jerk'em easier/cheaper stick with a bias ply, you can miss your chasis tune by alot and still make them work and there is no arguement to that when you want a tire you can mount up and go with no effort.

Re: power needed to lift front end

Traction and chassis/suspension tuning is needed to lift the front wheels. Like IHI mentioned, the difference between a sky high wheelie and a ProStock launch is how the suspension is set up. A high HP car with incorrectly set up suspension might not even get the front wheels off the ground. There are stock eliminator cars with less than 300 hp that can easily pull the wheels off. It also depends on the transmission. Automatic transmissions with a high stall converter and a transbrake make it a lot easier. A deep gear in the diff will multiply torque more and as long as you maintain traction, that extra omph helps lift the front end. It's not uncommon for a Stocker with a 30" tall tire having something like 5.13 gears in the diff.

I had my ladder bars set just below my car's anti-squat line. It launched hard and only pulled the wheels a couple of inches off the ground. Over the winter, I've recalibrated my suspension geometry and the ladder bars are now above the anti-squat line. I expect to pull the wheels at least a foot off the ground now especially with the new engine. With a very nose heavy car, I need all the weight transfer I can get.

Re: power needed to lift front end

i may go to a slick/skinnies. im gonna get the proper tuning also. I havent started my build-up yet, but i am planning on it for abou 6-9 months. Getting the front wheels off teh ground is not as important to me as the Et. or safety for that matter. I just think it would be cool to leave on 2 wheels.
