As for that set you have, I'll keep that in mind, but I'll also have what Mark spoke of in mind too (especially if it's cheaper)? Right now I'm dealing with some other looming possibilities for 2011, and my funds are focused on that. Furthermore, my car and I are over 900 miles apart, and it's getting snowed on...however I'd prefer that to being outside in the summer-time temps and wind/dust storms we had the previous 2mths.! Thank you, and you too Mark, for some options that will get me those highly appreciated 4tenths I will greatly appreciate the next time I race at a humid track like Topeka!!!
Gary, The 3.73 ratio in your transaxle is accomplished using a 3.33 planetary final drive differential unit and a set of 33/37 drive chain sprockets. Both combine for an effective ratio of 3.73, the best ratio available using factory parts. So you will be fine with that diff. I currently have a set of 33/41 sprockets for a ratio of 4.14 and will be moving to a 29/41 set next year for the 4.47's. That is the limit of the available room inside for the 41 tooth driven sprocket. Like I said, next year I will be testing to make sure that the input shaft of the transaxle can handle the increased torque input before I sell anyone a set.
