Engine

Normally aspirated induction:

Rebuilt ported cylinder head with:

• TODA 304 high lift camshafts
• TODA valve springs

Rebuilt bottom end with:

• Carillo high compression pistons

After trouble firing the fuel pump, I removed he wring loom, checked it all and added the required wires for the water methanol injection kit.
While I was at it I checked everything out and tifdied things up.
The loom is now returned to its rightful place.

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.
