Robert,

I'll still disagree. I've now run transmissions both in preparation for 
putting in the Turbo Audi. I stand with the numbers. You pay for the power used. Of 
course the main variable is fuel economy it the interconnection of the base 
of the reptilian brain with the control foot. Expending available thrust is 
fun. As to the clutch, for the larger diameter clutch to have more towing 
capacity, its contact area must exceed the gear reduction comparison in final drive 
ratio. At which point the trans is well on its way to toast.

The ABA block with 1.8 head has a much poorer flow efficiency than the 3A 
with the 3A 8V head. At that point, the ABA block only has the bore/stroke ratio 
going for it, if it has the squirters and forged crank.
