No not really just the add ons needed to run the super charger at that level like fuel injectors gt 500 fuel pump and so forth but those things don't really apply to my original question so I didn't list them.

Sorry I got off track. Get drag radials and Don't dump the clutch ever. Ease the clutch and gas together to get your forward motion established. It all takes seat time and you running a 3.25" pulley on a stock bottom end you either have some ***** or a spare motor

Stickier tires at the track will help most and the spin out on the highway seems a bit odd. Install lca's and See if that helps

No spare motor and my tuner that is very good told me that I needed the 3.25 pulley because with the long tubes it doesn't build as much boost because they move more air than stock manifolds.

With the 3.50 pulley I made 430.00 horsepower and 420 torque on about 8 pounds of boost. He said I can run 10 to 12 pounds of boost safely he has tuned several cars this way. Air fuel mix was almost a straight line all the way across. I will get my new numbers this Saturday when he fine tunes the smaller pulley.

Any suggestions on brand and style of LCA, do they need to adjust since my car is lowered? Is relocation really necessary for the street?

At 430whp it sounds like very safe tune. Please keep us posted on Saturdays results!!

Will do.

I too am using Steeda sport springs, but with D-Specs, and pretty-much all aftermarket suspension parts (lca, uca, panhard, lca relocation brackets, etc.).
Power to the wheels it a little more, but is also through an automatic.

Traction with street tires, like the Goodyear F1's I'm using, 285s in the rear, is very similar from a dead stop or slow roll: tires just spin when laying lots of power to the wheels.
I hit it hard once from a 60-mph roll, and it nearly threw me across the road into the other lane. Didnt spin out ever, though.

I just take it easier on the pedal when spinning can occur with loss of control.

For the track, I use slicks, and adjust the shocks appropriately. Even then, I can get loose on a poorly-prepped track.

As Far as LCA's go I love my BMR Billet control arms. They will run you just under $300, but I feel are worth it. I noticed a difference in launching the car when I added them along with BMR relocation brackets. The BMR brackets are nice but like all relocation brackets should be welded in if you are ever going to go to the drag strip with very sticky tires. I've heard that CHE brackets are nicer then the BMR ones but having never used them I can't comment to that effect.

Streets are like ice rinks IMO with FI. You certainly cant dump the clutch ever on the street. Once a tire starts spinning, its done, its not gonna stop until you let off the gas.
