Small update on this car. I got a 90% tune done on it yesterday (before it shredded the belt... original 120k miles 
) It pulls HARD. at wg spring pressure (12) it already destroys the old MPT70, we pulled it up to 15 psi and I adjusted the tune but then the belt let go. I can't wait to get this thing final and get some numbers... it feels very strong. After we replaced the belt, the rear end decided to call it quits. So the car is finding its weak spots, sooner all later everything will fall into place

a supra
my most recent ride to compare with is a 550 rwhp turbo ls1, and I think this pulls harder
I think it is making close to 600, but hte car weighs much less then average LSX car, so it feels quicker then it would be otherwise. Weighs in at about 3300 without driver.

I can only hope for those kind of numbers! I was working on matting a T56 to my setup but now I have to switch gears and look into rear ends.
Thanks for all the comments. We'll get the car up ASAP and get some times and dyno numbers (we need to turn up the boost some more first).

lol really!
The car made 614RWHP and 578 RWTQ. We maxed out the injectors and had Valve float @ 6K RPMS. The engine was built to to go to 7500RPMS. I have a moser rear end in the car now.
After the dyno the car spun a bearing. We had no KR through out all the tuning. After Byan @ LME took it apart he identified that the previous engine builder had an undersized con rod (the one that spun). Byran finished re-building the engine (this week) and repaired the other shops **** up. I'll be putting the engine back in soon. The springs are already upgraded and the fuel system is next.
Expect big numbers out of this engine very soon!

Will do. Here is a short video of it running. Yes all the kids were in school, and no it was not that fast. It was the first time it left my garage/driveway with the fresh/new engine.
Tiago and I are taking it to the dyno Sat. Next month I'll put in some 120LB injectors and we'll see what this baby can do!
