My original 901 (never been rebuilt) tranny lost second gear. So I have found a loaner 901 transmission while I have mine rebuilt. I'm going to go for shorter gears. Can somone help educate me to options around shorter gears for a 901 transmission. I'm having a shop do the work but I want to educate myself to what track drivers think works best for gears. I have a 2.4 that makes something around 160 to 170 HP and use 265/45/16 tires in the rear. I will mostly be just having fun doing track days.

Hi Grant,
I have a MSX box and it is great for Thunderhill, Infineon and Buttonwillow. I use a KaQV box for Laguna Seca & Streets of Willow I've attached my 'worksheet' that helped me select the right gears. gearcalc_msx.xls ( 29.5k ) Number of downloads: 244 You want to pay attention to the 'entry point RPM' for each gear. And like others have mentioned you need to tailor to each track. For example my KaQV box is great for Laguna, but I hit redline way too early in 5th for Thunderhill so I run the MSX box there. Hope this helps! Greg |
