Hello,
I am designing a cooling system for my 90 GSXR 1100 ( Oil Cooled). I am just wondering if anyone knows how many CFM approximately I would need to keep the bikes temp steady or at least bring it down? It has a few modifications like higher compression, Jet kit, Ported head, full exhaust etc.
I know for example alot of Italian bikes run twin Spal fans ( 5.2") that pull approx 350cfm each but, they are water cooled bikes. The way its going, I can most likely fit 2X250cfm fans right now without too much issue but I still need to do some measuring. My oil cooler looks curved, much like that of a Yamaha R1 if I had to describe it.
I also do not know how the heat dissipation compares with oil vs water??
Im just trying to decide on going with a single large fan or small twin fans placed on the far edges of the cooler right under the inlet pipes??
If anyone has experience with heating/cooling/engineering feel free to chime in!!
What you guys think??
