Sub-4 Engine-Anyone using one or have experience with them?

Is anyone using a Sub-4 engine? Or have experience with them? I have some questions if anyone can help.

I appreciate it.

Contact Neil at autoflight. I think he was associated with making sub-4 before he branched out and started autoflight.

I know the sub-4 is a subaru EA-81 engine... but its not the american version of the engine. It has special sub-4 high flow heads and higher compression. It uses a pair of motorcycle carbs and its supposed to be ran with av gas not lower octane auto gas

David Hopkins at Wauchula has one on his two place dominator

Thanks Ron.
