Dyno Time

Spent some time on the dyno at Autotech during the week.
After ironing out a couple of bugs, we got to the tuning.
Made a massive 12rwkW at about 3000rpm before we pulled the pin with air intake temps in excess of 100 degrees C, a problem I had expected.
Now going to water/methanol injection for charge cooling.

Exhaust

Custom exhaust just built by Powatone at Fyshwick, ACT.

Terrific looking job - 2.5 inch mandrel bent through a hotdog muffler, then 2 1/4 over the diff.
Great looking exhaust, but a terrible photo.

Better photos are available here.

Ignition timing....

I found this example of an ignition timing map for a supercharged Toyota 4AGZE somewhere. I might try it on my application as at the moment I've got no torque above 3000RPM.
