I LOVE IT!! With these formulas, we can always blame the engine, not
the driver for slow 1/4 mile times. For example,a driver who normally
runs a 12.00 1/4 mile misses a shift point, and records a slower 14.00
second time. Driver error-NO WAY!! What really happened was the engine
experienced a sudden and unexpected decrease in horsepower! :)
In all seriousness, I think I will run these formulas against some
articles in Road&Track, and see if they pan out.
Also, I have a marine DYNO in my garage, left over from the days of
when I owned a boat repair business. I have toyed around with the idea
of adapting it to VW's, maybe by modifying a tranny case,etc. Just
another project to deal with....
BTW, anyone want to buy some boat parts!
