Another hectic day at the dyno.  We laid in a base fuel tune and then went to play with the boost tune, and everything was going well until suddenly the car shut off and wouldn’t start up again.  This was easier to diagnose, though.  Dead fuel pump.  80 miles or so on a Walbro 255HP and it’s kaput.  Really bodes well for continuing to use that thing…

In any event, presented without further comment, 298.6rwhp, 220.7rwtq on a Dyno Dynamics:

We didn’t get to playing much with the bottom end before the fuel pump gave out, so that’ll have to wait for a future session.  In the interim, this is more than enough to play with for now.  The torque curve is super flat, and could probably be flattened  out even more (mostly the bottom end) with more time tuning.

Tomorrow, a new fuel pump comes in (overnighted), the car gets cornerweighted/aligned (assuming the fuel pump goes in), and we try to assemble the rest of the seatbelts, passenger seat, hood, fenders, and the front swaybar.  Then, if all goes well, I try to take it out for a first outing at Pacific Grand Prix (a local big go kart track that has car lapping days twice a month).  That should vaguely approximate an autocross experience, at least enough to get some basic setup info dialed.  Hopefully tomorrow I’ll have a picture of an assembled car, finally…
