Drove up in the rain-made it on the Dyno around 3am.
First pull, no changes-20psi (creep to 22 by redline) 450whp/400ft lbs. Full boost by 4.8k

AFR's were a bit lean for me on pump gas 12.2-12.5, so I turned to fuel up. Made 468/413 next pull with 11.2-11.5 AFR's.
Go to 110 leaded "pump" gas, play with restrictors for a few pulls-get it to spike to 30ish psi, and hold just under 30ps to redline (only 7k, since my stock Hyundi head/cams own me)
564whp 490ft lbs trq. With nice and thick 11.0-11.2 AFR's. It was 4am, so we went to stake and shake. I dont see the need in trying to get the tune "perfect" with all the junkyard parts on the car.

With how responsive the system is, I would have to say the Twin turbo setup works, and I think I will be refining it over winter. Both turbo's still feel mint, and both compressors are 100% perfect, even with well over 1000miles of flogging with my "ghetto" ram air induction.

I will toss a good head on it over winter, with Cams I already have for the car. I do expect to make anywhere from 100-200more whp more, since I will rev it to 8k, and the power will climb all the way to that point. As long as ti does not run out of turbo, or the lack of good exhaust flow does not choke it up, it seems like it should beat the Colt's 708whp.
The kicker-you can duplicate this fro $4475. Although I did not spend that much, thanks to always scavenging for cheap used parts, and my Grandfathered sponsors JMF and DSmlink, if you have a harbor freight mig welded and a little bit of time, you could have quite the FUZION for less than 5k total investment.
