Hey fellas. Looking to bump the power a bit and after a bit of research on and off this past season, I'm not entirely sure how to go about it.

My 01 ZO6 has a forged 346 with oem compression and put down 638rwhp. It has the A&A Vortech V3-Si with a 3.4 pulley at 12psi boost and a Speed Inc SI2 blower cam. The car is Speed Density and a return style fuel system supposedly good up to 750rwhp. LG Pro Longtubes, no cats, and BB Bullet catback.

I'm curious about a few specific things, but of course will listen to any advice you guys have. Not interested in e85 or the YSi.

1. What kind of power gain can be expected going from Si to T-Trim head units with the same 3.4 pulley? Can the T be spun faster yet with a smaller pulley?

2. What kind of power gain can be expected adding meth injection to my original setup, and with a T-Trim?

3. Any other recommendations for additional power?

Scrap the whole thing and go Twin Turbo?

Sell it and buy a Prius?

I made 850/rwhp to the tires on the T(Novi 1500). Guys are making 750's on SI's. I'd add a 2200(non R) blower. Should be good for 100hp or so over your setup.

What other modifications were done?

402(made 800rwtq but won't make a big difference in hp). LS3 heads, a custom cam I speced(232/244 118+4) to idle like stock. 1 7/8 Chinese headers, pump gas and meth. Hit 846, 847, and 850 on 3 different dynos. 6 rib Novi 1500(T trim with a 3.125 pulley)
