Whats the turbo plan now Simon?

Standard comp ratio with a light head skim. Very good intercooling and plenty of E85.

Yeah, i was was a bit dissapointed, but not too stressed, had it all rebuilt and back in the car within 2 days. Im going to go away from the coil on plug setup. It works well but it takes too long to check plug readings and do leak down tests. I`ll probably use either IGN-1A coils with built in ignighters or some good local bosch coils and modules.

I love this project Sikyne, too bad I found it now and wasn´t able to guess the powerreadings before you got the result!? Sorry about the meltdown, I know how it feels after 10 years of turboing the A-engine! This gives me a clue what sort of power I could expect from my new turboed A16!? What is the comp.ratio in your engine? If I haven´t proven that the A-engine is an option for turbo estups, this thread sure proves it! Get it back running and go kick some ass!!

Cheers, Marcus

sorry to hear about that sikyne ,i have been watching this thread and the power figures are amazing ! i cant believe a stock set of pistons can hold up to so much abuse !

hope you get it going soon and get a video up for us ,best of luck !

To be so close and yet miss out by some earthing issues is painful.
Hope you get another a12 going soon with the same finely tuned setup.

something so small did so much damage... thats horrible and to put in a marathon effort to get outed by a burnt coil... at least you sound semi-positive. keep up the good work.

interesting to be able to discover the problem by data recording i presume?

just if you had a smaller turbo on for this engine you wouldnt have just killed your good one

Damn, thats a shame. I was looking forward to seeing the footage of your car racing :{

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.
