Not to bring up such an old thread but I stumbled across this today and I believe I now own this car. It's changed quite a bit after Taylor bought it from u, and then I changed it some more.
Still on the APS kit with some upgrades, it now makes 946whp/899ftlbstrq on e85 @ 18psi.

The previous owner blew up the motor Chris had in it and it's now a 6.0 LS2 block fully built with worked 243's. The turbos were also sent back to FP and upgraded with billet wheels and clipped turbines. That bumped them up to 70lb/min each so the car is capable of a ton of power. The only reason it's where it is now at 18psi is the gate springs being 9lbs and the controller only being able to double the gate pressure.

This gives me hope. I've got a forged 377 LS3 short that previously did around 825-850 with the LG 70LB/min turbos. I'm upgrading the heads to a set of Mamo 235 NFI and a Mamo cam........which should be significantly better than a good set of 243's. You might have just motivated me to start getting the work done, lol.

Street car takeover is here in Denver in a few weekends and I'm hoping to hurt a lot of feelings from the out of towers who don't know theres 2 snails hanging underneath haha. Hard to hear them over that cam/exhaust until it's too late.
