I am planning on running 4.30's in my nine inch along with 27 inch Hoosier Quick times. I have FULL suspension bolt ons in a non-lowered car. I also plan on using a Street Twin and heavy duty drive shaft.

I want to break 11's and I think I will need an extra push. If I use the 4.30's and a 75-100 on a 350rwhp (na) car, what is the expected outcome? EG: is traction going to be non-existent or is it just going to be a matter of proper driving?

Well, right now with 345 rwhp, 26" tires, and 4.10 gears, my car goes through the traps at about 6200 rpm in 4th gear.

With that said, I don't think you will have a traction problem (you might), but I would be more concerned with what rpm you will be going through the traps at. You will probably need to shift into 5th gear on the spray with that combo. I know somebody could do the math and figure it out exactly, but that's my guess.

You could probably get into the 11's with an aggressive launch on motor, IMHO.

 

I agree with Ponyhntr, I think you're going to need to shift into 5th with that formula. I have a friend who put a 150 shot on a basically stock '94 (just had CAI and cat back) and ran an 11.8 1/4 mile! This was an A4 with 3.23 gears.
