Need help making car faster. I need to go 9s.

[Demonio]

Have a cobra 4.6 with a 3.4 crusher on 24 psi making about 750 rwhp on e85. but now I'm thinking of adding a 100 shot. There is a couple cars at the track faster than me and would like deep into the 9s. I Never used nitrous and been readying about it but don't see much info on crusher kits and e85 plus nitrous. So any advice and what do I need to get the most out of it. Injectors flow 2250cc and fuel is dual 400 pumps..
Side note my suspension is all stock besides some adjustable strange shocks in the back front all stock.



R/T... .476
60" is 1.638
330....4.422
1/8.....6.724
Mph...106.39

Tire pressure is 10 psi..

You already have the power for single digits, just work on putting it to the pavement.

Yep. That 60' isn't getting it done for you. 1.4x with your current power level should get you closer.

Go to the track and practice, and get your suspension dailed in, there is 9s as it sits, dont be so quick to add power get some seat time on that setup, should be able to get into the 6.50s at 108-110mph in the 1/8 as it sits

What do you guys recommend for suspension mods to help me with the 60"?

I'm using Mickey Thompson drag radials 275/60/15

Op i was using Mickey Drag radials as well couldnt cut below a 1.9. I swapped to Mickey thompson stiff wall drags with a tube in them. I think the number is 3057 but i cut a 1.5 60ft straight off the trailer last week.

I agree about the slicks... A radial for a stick car is the wrong tire, and 10psi is way to low for a 275 60 radial. 15 to 17psi would have been better to keep the tire's footprint uniform.

Car is auto

car still have the front sway bar? auto car with that sort of power should be in the 1.3x to 1.4 range

Oh sorry, I assumed stick being a Cobra. What trans & what's your race weight? 106mph in the 1/8 at around 3900lbs is more like 700whp, not 750.

What trans & what stall rpm?

I concur....haha

Th400 stalls at 4500k and weight I haven't weighed the car but prob around 3900. No front sway bar.
4.10 gears

You should be able to 60' better. One other thought, what is the DA in Vegas like normally?

 

[Demonio]

It's almost 2000ft DA
I just ordered a teamz ss1 kit in hope it can 60 better. But car goes straight not much of twisting the chassis, but maybe bushing to worn out.
