The
Bowling's Aerodynamic & Rolling Horsepower Computation calculator is an awesome tool(toy). I put in my cars' frontal area, weight, 130mph for the speed, and got 57hp required at Cd 0f .18 and 60hp for .19. The 1.6 diesel I have had 59hp when new. I guess this will be a good match up to see where I am when September rolls around.
I got the 5th gears and fork out of the ACH(diesel) trans, and am going to try to swap them out tomorrow night after work into the AUG(gasser) trans, dropping from .89 to .75 in 5th.
