Gents need some suggestions first time with a B44.1 but ive been racing for years.

Im currently geared at 22/81 and the drive train feels as free as one can get. Gear mesh a little snug but ill loosen that. Running a Novak 10.5 with Tekin RS boosted about 40%. Drag brake 20 pretty much what Tekin racers are running from their web site!

My temps are extreme Hot running 240 or better and obvious reasons my motor is slowing down due to heat.

Any suggestions?

Take boost out?
Smaller Pinion?

I know its going to be hard by not looking at the car but....im stomped!
