Thanks man.

MY plans are a D-1 Procharger w/ 3 core I/C and prolly meth injection. But I'm still keeping the bottle. lol

how much boost? That what i want to do.. Did you get your compression ratio?

ZW99GT

I keep getting 1.4?????????? I don't know what going on. It's somewhere 10.5-11:1, which CAN work, b/c S/C mach 1's have 10.5:1 stock. It's not optimal by any means. But with the I/C and meth it can be done.
