I got one he351 i know thats what most 12v and 24v and 03-early 04 guys switch to but i dont have any of them ive got 4 hx35s and 2 he341s. I know the 341s would be the quickest spooling was worried about drive pressure as a gas engine is going to be prone to detonation and my setup is already going to be on the ragged edge of destruction:finga:.
