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.

New Exhaust being built today

2.5inch from extractors, hot dog centre, 2.25 over diff...
