what the f**k man, you talk about how good drifters are all the time go round and see how many of them are running no shrouds with standard clutch fans, and tell them it wont work.
and i dont think were are talking about an rb20.....so stop talkin about them.
and for those who want to create less drag on their engine, then look at putting a flexy bladed fan on in place of your big plastic one, they are genius work. pull shit loads when your stand still and less and less when you are moving faster and faster....genius, alot of dragsters use them. oh and that wiegh fark all so have stuff all inertia.
