    How does the 100 engine handle going for more top end?

    At my local track, Im topping out before I even get to the straight.

    The stock gearing is 14/50= 3.57

    Im thinking of going to 15/50=3.33

    http://www.gearingcommander.com/ shows that this will gain about 4MPH on the top end...

    It'll pull more than the stock gearing. Finding the magical point where you fall on your face is tricky though. WIth so little HP on tap, your weight will play a big factor, or at least it does with my big ass.

    I weigh 175. Stock it will pull me on a 15-49 and still tap out.....
