Thanks Garry

For taking the time to write that up.
The results don't really surprise me... and confirms that they do have plenty of potential.
However as you mention, there is ALOT of time involved and I don't think people without some reasonable experience/decent tooling should try it?
Alloys actually "need" compression. Their higher heat coefficient means they suck alot more heat out of the combustion chamber than irons do.
What does surprise me is the amount of mods/work that was involved to get to 11:1? A huge amount must have been taken out of the combustion chambers... are those cc's quoted, actual or estimated?
