FAST!!!! 30PSI
PT88 is here!!!!!!!!!
basically the same setup as a turbo buick
low low compression high boost 7.0--8.0-1
good on the street because you are killing alot of torque
with low compression which means launching and not spinning,

never heard of 7.0 to 1 compression
buicks are actually 7.8 to 1
sorry if i wasn't clear. i get that way sometimes

Hmmm....6.0L block, 4" bore, 3.27" truck crank, long rods, 7:1 cr, 7000rpm, 18-20lbs of boost. Sounds fun.
Oh, and two smaller turbos that actually fit in the engine compartment.

because that is what you get with a high compression low boost combo
low compression high boost is what you want
turbo buicks are 7.8-1 and I ran mine @ 20 psi on pump gas
it didnt spin on the launch,a little in the bottom of second
but no V8s got me on the dig!!
that same combination was used on my boss's(bunner engine development) 8.50 alcohol motor
7.0-1 compression 30PSI on a 6-71
it is the right combination for the street
=
that is all in combination how your motor reacts,different size AR will produce
different spool time.
so what you want on the street is a car that hooks out of the hole,if it spins in the top of the gear fine,because it will be moving forward still with the right suspension
setup
that is the way all my turbo regals reacted
different spool time.

I would highly reccomend stepping that CR up a bit. My motor is 8.8:1, and its pretty soft down low. I higher CR will help the turbo spool faster, smokin hawk is right.. with really low CR like that, you will have more lag, but then with all that boost you plan to run you will blow the tires off the car. lots of torque doesnt hurt traction, its how fast the torque comes on.

94 LT1 Camaro, Turbo. 660rwhp/660rwtq on 12psi and pump gas. more to come.

like I said smokin hawk is right if you want to blow the tires loose
8.8:1 is a petty good CR for the street,you dont like being able to launch?
I am quite ceartain that my combo will work perfect
soft down low is what I want, I dont want the turbo to spool up fast
I want full boost by the beginning to middle of second gear off a idle launch
I have owned two 10 second regals stock CR and I know what works
spool time has to do with convertor selection also,I will have a convertor that I can have a 10 psi launch and off idle have my second gear full boost
there is no reason to try to persuade me any other way
I appreciate your input but my combo is for 20psi pump gas
I know how my regals ran and I want the same with 8 cylinders!

You just said the regals ran 10s, and you want 'the same performance with 8cyl'. Thats not a very lofty goal. with I know for a fact that a 9:1 PUMP GAS LS1 will make well into the 8XXrwhp. Why sell your self short on 10s, every street car these days seems to run 10s!
But, if its mainly a drag race car and/or a big converter.. it may not matter because you wont have to deal with the loss of drivability (the converter will 'slip' right though it)

Good luck and keep us posted. I'd like to see what a 7:1 or an 8:1 FI'd LS1 would be like.
I thought that GN's are 8.5:1. My only thought is that an 8:1 LS1 might really crawl until it hit boost and then it might be like a turbo import that blows the tires away because it just go nuts and goes from 200rwhp to 700rwhp in a very short period of time...
I wanted to do a 8.5:1 LS1 but folks pushed me to the 9:1, but if I did it again I would probably do 8.5:1.
You'll need a good fuel system for 20 psi.
