Its been too long but its back on the dyno and getting ready for the track...

The manufacturer could not explain why the supercharger failed. They verified no foreign objects, no lack of lubrication, etc. They started mumbling on about "pressure waves" or some BS but when I provided datalogs and pics of the bypass system they had no reply.

The new supercharger required modifying the intercooler bracket but everything else was pretty straightforward.

Unfortunately the pulley the retailer specified for the 'charger is too big but I've got my hands on smaller ones that should give us ~15psi.

The cold and hot-start tuning and transient throttle tuning is all done, which is great. I'm getting ~310hp at the rear wheels with ~7-8psi. Still looking for ~425hp with 15psi. We'll see on Tuesday!
