Not sure dave but im running the biggest coil recommended and still there is a chance of melting the rotor button or dizzy cap if i go any bigger.Its showing no signs of not being able to ignite the e85 on current boost levels and i very much doubt i will be increasing boost if anything i will come down...

Today i secured another head "but" im going to finish this one off and test it on the car just to prove a point and the oval head will go on the next engine I have reshaped the combustion chamber and Unshrouded the valves,I still need to finish areas off

There isn't alot of difference between the two styles of A12 manifolds both plenums and runners are about the same "measurement" and volume I have the other style on the car your talking about "D",but the casting is a lot heavier .
But the new manifold is alot larger and with the ports now being matched to eachother. The bigger difference is the larger volume i have :)I need to try to increase Hp but drop boost down.
Supafatto...sounds good im worried about the engine at the minute brakes will be next
cheers anthony

Cheers mate its all good re worked the manifold so you can see there is quite a large increase in runner size and also the plenum has increased massively.
Still need to speend a little more time on the head there's a few areas i want to address

Hi all chasing any performance cam suit A12 that maybe lying around,gathering dust I need to start experimenting.
Give me a PM if your able to help
Cheers anthony

Did the inlets today,which was a pain in the ass as i wanted to increase the port size but not the port floor....after a while I was able to dial in the head which once done speed up the process.
What was intreasting was i had ports from 25.7mm up to 27.5mm I think there is a lot to gain from portmatching head to manifold.
Now every exhaust and inlet is the same,I will start the inlet manifold,then go back to finishing the head
Some of the pics are a little poor but you get the idea
