Engine Torque/RPM Numbers, Race Motors Options

[Britain Smith]

I am currently working on a series of excel sheets to provide a wealth of information related to both the 901 and 915 transmissions. I need someone who is an experienced racer who has knowledge of there torque/RPM dyno numbers as well as there transmission gearing so that I can verify that my calculations work. If would be able to keep these numbers confidential if you would like. My calculations should be able to calculate optimal shift points, gearing torque numbers, and so on and so on. It also has all the available 901 and 915 gear ratios and will allow you to experiment with each. I know someone here has these numbers, it can be either for a 4 or a 6, but I need to know your tranny numbers also.

Thanks,
Britain

For the 901's, the "gears" spreadsheet that has been posted here seems to have all the info you'd need. You do have to plug in your tire height and approximate engine torque curve. I have not been able to find detailed HP/torque curve data for the early factory cars, though. If anybody knows where that info can be located, it would really be helpful.

I have been using a slightly tweaked version of the spreadsheet, where I fiddled with the redlines and added a few (flipped) gears that were missing, reformated the display slightly, etc.
