346whp before FD alternator and new Cosmo fuel pump.

After the half-bridge build-up, Rotorsport Paul in Santa Clara added a Masterpower 60-1 Turbo with an external wastegate, Apexi Downpipe and larger (*big*) exhaust and Tien Coilovers. Steve Kan did the retune. Boost creep gone, but dyno power limited to 346whp due to voltage drop probably caused by the taurus fan and maybe fuel pump starting to fail.
You can see the squiggly lines on the dyno chart as it attempted more power at higher rpm. Especially the torque struggled and started to flatten as low as 4500rpm.

Lots to do yet:
Telematics Computer w/AM-FM Sterio beta completion.
Seats upholstery.
Methanol Injection.

New paint - maybe something fancy with a RX-8 Metalic White and then some hood, fender, and door designs in a subtly lighter or darker metalic white. Don't want cheezy.
Cold air box.
Hood vent (someplace) for hot air exit
