TheEnemy is right; I have a Zirgo 2700+ Efan, and have used it for a couple years. I found it is best to mount it partway in the shroud, instead of mounting it right on the radiator. The shroud helps it pull more air through.
Blu3Z3, you might try a set of HO cams. I have a set but haven't gotten around to installing them yet. That and a new Ypipe, and maybe a different muffler.
