They then would be around 200-220 idling, and go up to 350 while racing. And thats with a fan setup running off of flywheel, so fan is slower at idle-faster while on the gas. I also tried an electric fan setup, no go, not enough air flow.

And i tried using crankcase pressure to fuel tank. That works but varies with speed of engine. So you get inconsistent performance. Now if you could fit a pressure regulator in there it may work, have not gotten that far yet. And if anyone could recommend one ill give it a try.
As i think the regulator setup would work awesome. The fuel pump is still kinda iffy when it gets dirty.
