Check out this 727 blowup

nope it didn't blow up on the shift. It was topping out in third gear, and he was just about to get out of it and shut it down. It let go roughly 5000rpm.

on the plus side, the AFR was right and intake air temp was pretty good. The truck has the Eddy ProFlo MPFI set up, driven by MegaSquirt3, and boosting by a stupid big turbo. Buddy had just gotten the bugs worked out of the ignition, and got the blow off valve and wastegate set right.
