The exhaust air reclaimer is another system all together,haven't seen it.
Never know an EPG to be used on the buggy.
The winding directions are in the tech brief,all clockwise,and in the same direction around the core.
I don't know the number of windings,but I know that I described the bobbin and core sizes on this site somewhere else.You'll have to look for them.
No no one has tried to put anything together to test.It's not that easy to just through it together.
The owner doesn't understand the tech,so he won't try anything that might damage it.
Thats why he needs funds,to put together a team to do just that.It will take money for that alone.
