Top end cooler?

[Billdog350]

I have seen a few guys whos sigs show that they have a "top end cooler" mod on their 400ex? I've never heard of it. I have heard of the air scoops but I assume this is something different? I tried to fit a foreman 450 electric fan in my 400ex engine compartment but I can't seem to squeeze it in there....but I would like to make sure with a high comp kit that I don't have any problem.

havent ever heard of it some one knows i am sure..... i would think it would be air scoops because they are made to cool you engine off some at top speeds

Top end cooler involves an additional oil cooler, and then the oil line re routed so it taps into yout cylinder head cover. Do a seach under '400ex cooling'. You bound to find alot of threads on it.

yep search for or contact Mickey Dunlap on the FST cooler.
