Its all miniscule though in retrospect.
4.1-4.667 = .567
.567/4.100= .138
so a 13.8% increase over stock. So every RPM you cruise at, add 13.8% to it. Im assuming subtract 13.8% from the normal MPG, given all conditions are the same. |
But it's a 13.8% increase in thrust at a given speed, which means faster acceleration. Also depending on the course/track it could put you in a better rpm range, like say instead of constantly shifting between 1st and 2nd, you can stay in second and still be where you want in terms of rpms. That increase can make a big difference on a track. As far as cost mpg wise it's not as simple as taking off 13.8% and there's too many variables to really say with any certainty. As far as top speed that's a really simple problem assuming you have enough power to top out sixth gear.
