>>>*Uhh...*LOL** 20R? That is another tech article, and about as long as the last one that took me 3 hours and I still didn't get a lot of stuff in there.

On torque, well, that is what you feel, horsepower is just math. But horsepower is what nearly everyone asks for so that is what everyone tries to figure the numbers in. I would expect about the same percentile increase, around 25% or so.

*Mileage? How the heck would I know? I do know that in several sustained throttle tests there was no lbs/hr fuel use increase to really speak of with any of our setups, but there are thousands of possibilities I never will live long enough to see charts on.

I do know in the real world our 261C does the best on economy of what we have available and also makes the best power under 2800 RPM or thereabouts...*EB.
