I went to the track the other night and ran a 12.3 at 113mph. So I got some improvement, trans still isn't shifting where I would like; letting off the pedal to shift. Then on my last run I blew out an exhaust manifold gasket. Upon disassembly I found that I have a few cracks on the inside of the turbine housing? How serious is this?
Cracks are common and they will get worse over time. They slowly grow under normal use, quickly grow when you blast them with high temp exhaust during 1/4 mile runs. I'd say it took me 300 1/4 mile passes from the time of first cracks to complete external cracks and destroyed exhaust housing.
