70duster 360 gets hotter the faster i go

Well good on Tyler. Those 3 inches add up to 15%. Get out the jigsaw. Do not pass go. Go straight to jail.What were you thinking?Whats the point of a 26 inch rad in a 22 inch core support? I could be mad if it wasnt at least a bit funny.You will joke about this for years.Now go push Tylers thank button.
As to cutting the core support; I think I cut the top and bottom, and then folded the metal over to 90* on mine. I thought it might force a bit more air through the core at speed.Kinda like a funnel.Since I never ran it as a 22, I cant say if it works or doesnt.But mine has shown no tendency to overheat.

So what about the lower hose?
