Ok, found something kind of interesting..I'd heard about it previously and JEGS is now listing it on their website. I don't quite believe the MPG and hp claims, but it's a variable speed fan and if it fits, should work quite well with the VX. Anyone know the radiator size off hand? Here's the link:

If that doesn't work, www.jegs.com and type in 400-295 for a part number in the product search box.
