I had a major melt down of this engine on Wednesday night. The engine runs coil on plug ignition and they have built in ignition modules. The earths for these coils are in pairs, The earth for the front two coils came loose under load and was triggering the coils each time the earth lost contact making the coils fire the plugs at random times as well as when the ECU told them to fire!!

The end result was cylinders 1 and 2 runing into detenation and sending bits of piston and rings out the exhaust valves and through the new turbo.

2 stuffed pistons
1 damaged head
2 bent valves
1 stuffed turbo

Not the ideal preparation 2 days before Winton!

36 hour rebuild!

New pistons,rings, reco the head, S-hand turbo and hone the block. I also fitted an EGT guage this time.

Friday night back on the dyno to retune.
I only had non resistor spark plugs so used them. but this cooked one of the coils, effectivly puting me out of the racing on the weekend.

Next round is at Philip Island in 5 weeks.


I`ll take some footage of it and post it up. It`ll be a few weeks tho.
