My friend has a 4BT Frito Lay truck (14 foot box), and I think he gets about 20 pushing gobs of air.
Its a little slow, and a gear splitter would help it a lot.
He does get substantially better mileage than my 6.2 turbo 4x4, his manual 4 speed vs my TH400 may be a factor.
Best torque I have heard from a 4BT is about 700

You might end up about like this?
