On the MT-82, fourth gear is 1.32:1 and fifth gear is 1:1.

So fourth gear on the new cars is just like running around in third gear on an old T-5 (1.34:1). When you figure that all Bosses come with 3.73s and the Laguna Seca has ~27" tall rear tires (285/35-19), you can see why he would need to shift to fifth for the quarter mile, even with the Boss intake/heads/rev limiter. He's trapping over 91 in the eighth so he should be around 116 in the quarter, but fourth gear won't take it all the way there.

Or switch to some 28.5" tall tires like I did and keep it in fourth. :headbang:

Great job Matt! I still can't believe it was hooking like that!
