Could be as bad as 4 mpg [highway] worse after the change.
But then again what's 120-140 extra gallons per 15,000 miles of highway use compared to a possible 0.3-0.36 seconds reduction in quarter mile times. Assuming you have the redline to not add another gear shift into the mix.
I.e., the rear torque gets multipled by 10%, take the cube root of the change..............2.2 .......
14.5 secs x 0.022= ~ 0.32
Thats a massive gain. But on a $ basis it is expensive.
Just like each 10 HP gain knocks ~0.1 second off the quarter mile.<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">
