How much rwhp to hit 11s with turbo???
 

How much rwhp would a person need to make to hit high 11s consistently with a single 70mm? Car in question is an 01 GT, 4r70w and let's say cutting 1.8 60' times.

Also, with a turbo what WG spring would you need to hit that power level through the auto?

(If on lower boost) Just use a 7psi spring and use a boost controller to up it to what you want. You can always go higher than your spring pressure, but never lower.

I don't know how much lighter your car is than the newer models but a couple of guys with over 400 at the wheels in the 05-09 models are still not hitting 11's. I've never driven a turbo mustang but 808muscle has about 425whp with a supercharger and his best is 12.2 on ET streets.

you're gonna need about 400whp imo. to get there on a turbo you wont need 12psi, prolly more along the lines of 9/10 with an intercooler and stock h/c/i.

Need to know a little more about the car and how its getting the power down. Stalll, gear, tires? Weight reduction? With a good stall and a tire, and 3.73-4.10s it could be done easily on 350-370 rwhp. Wirh weight reduction, even less power would be needed..

Stock stall, 3.27s, just DRs (hence why I said assuming 1.8 60'), no weight reduction other than tubular front suspension, 175# driver.

if you're hitting 1.8 60s then then I don't think 350-400 would be a bad guess.

The question is can your current suspension/tire/gear setup cut 1.8 60s with 350-400whp.

This^^^

And with that turbo and no stall, it's basically going to be leaving on near stock power and a 3.27 gear. No bueno, IMO. I don't see a 1.8 happening. Gotta get that turbo going or either gear it. I think with a tire, 3.73 and 4k stall, it would be a beast off the line. As it sits, 1.9 to 2.1 60s all day.
