Well here we have another use for NOS ,you could use a 250 shot to take care of the lag or the current more popular route of co2,My friend has the fastest street car in the states using these setups in a 95 notch back mustang (I know not a mopar)running in the 6 .70 range.

Depends of the size of the turbochargers, and you can also "cheat" bigger turbos to make pressure even off the line burning fuel in the exhaust port by retarding the timing a lot. But for this, you need EFI and computerized spark control. I made shorty headers for the turbos. Short because willing to retain as much heat in them as possible. Our turbos are twin entry models, which made things a bit more difficult.

THAT sounds like it'll be a butt-kickin setup!
A few years back when I bought my first Fury I was going to single-turbo a 440 for it; actually had a place in Nashville do the research on correct size and everything but I got scared about fuel delivery and streetability with a blow through carb.
With EFI that's gonna be a KILLER! It may be a headache to set up, but it'll be worth it!

Seems to me like domed pistons? How do you end up with 8+:1 CR for the turbos?
Our car is not tube chassis, it's backhalved stock chassis with the inner fenders removed in front + a roll cage. The front subframe is stock, except that it's now solidly attached to the body. It's a street car, so of course there is a wiper motor! It's even got dual mirrors!

the guys at the machine shop and I questioned the piston design when they came in too, but we kept putting everything in the computer over and over, and It came out right. I even called ross when I got em and they just told me to trust em.they follow the shape of the chamber very well. ross also moved the rings down a bit on the piston to help keep em away from the heat as much as possible. super light, floating pin, everything I ever wanted

Interesting. I calculated with a .040" thick gasket and 5cc valve reliefs flat top pistons, zero deck height, 88cc chambers, and got about 8.7:1. I have not received my pistons yet, but we shoot for 9:1 with dished pistons. We have more displacement though, at 478 cu in, and very smasll chamber heads, only 60 cc's.
