Is it possible to run a fully built 454lsx on 20psi and 10.5:1comp, and for it 2 live??? looking at running a rear mount twin turbo kit, and run it on e85 on the street.

This is my dream build. It's gonna have to wait until after college though!!!

20 lbs of boost for a street car? That's going to be an interesting, if expensive ride. Better be getting a good degree in college to afford a beast like this.

If you are looking to make 1500+ hp, are you sure there are not other options to consider that might cost less and be more reliable? Might be less expensive to build a large BBC and use less boost to achieve same power and have a combo that will last longer.

or start with 5psi...cause you'll still **** yourself when boost hits...lol...then go from there...

build it for 20 psi but i bet you will only use it up to 15 psi maybe 12 psi on the street

I have a 427 boosted on the street with drag radials anything passed 15 psi is a waste on the street and 15 psi is a wild wild ride

How about you put the fully built 454 LSx in the car first, then tell us its too slow for the street and needs twin turbos

I planned on only running 10-15psi on the street and 20psi on the track, but it needs to be able to handle that 20psi when i want it. I just wanna push the envelope, i dont want to build it to 700hp and then decide i want more and do it all again, i wanna do this once and do it big. I plan on running methanol or alcohol injection just to be safe.

What about E85?
