Saw that all three bullseye units blew apart with only a few dyno pulls.

Gotta say they are very impressive turbos spool wise but they need to get the reliability up especially when used at these extreme pressure ratios. From what I saw the problem is in the trust system but I'm not a turbo expert!
It's getting there. Gotta keep at it and try to improve. With the new turbo it allready ran 1 mph faster(154.32mph) on a bad take off which resulted in a 2nd gear bog. Didn't get to make a second pass because the accessory belt tensioner broke again. Seem to be a new weak link in the combo. At least the car is consistent 9's. Just need to work on the launch with the new setup.

With the 1.0/T4 turbine and it's on boost only with C-16 fuel.
One on the dyno the rest at the track.

Thanks very much.

....yadda..yadda....over my head. I believe the guys at forcedinductions are working on a 360 assembly for the Borgs now, plus I know they built a couple of dual ball bearing S400's, so maybe that will take care of the problem. Anyhow the car looks very impressive and makes me really want to look at getting an EVO now...lol. What tranny is that car running??
