I am actually looking to average about 40kph, since this will be a continuous 7% hill climb for about 11 miles.
So the pie has to handle 2500-3000 watts non-stop
On a 20" wheel, i will be running a lower RPM as well.
I was going to locate the fans right in between the edge of the cover and the disc brake mounting holes like zappy did.
If so, do you think the fans are going to benefit me, and... i do think that seeing the dyno information would be interesting if you can post it up here.
