Hi rotary maniac. S5 rotary motor has been modified with Toyota W58 tranny and Hoosier drag slick size (26.0X9X15 D05). What's the rear end gear ratio suit for above setup. Example 3.9, 4.1, 4.3, 4.55, 4.87 or 5.1. https://www.nopistons.com/forums/pub...1047683664.gif https://www.nopistons.com/forums/pub...1047683664.gif https://www.nopistons.com/forums/pub...1047683664.gif

What the hell, I replied last night.



First off, wrong forum.



Anyways, you need to give a lot more info. What rpm do you shift at, what mph range are you looking to get out of the gears, is this goign to be for street or track only, etc?



I have an excel sheet that should tell you everything you need to know. Send me an email, and Ill reply with the spreadsheet. That goes for anyone that wants it, I have seperate sheets for TII and n/a's. I cant attach the excel sheet here.

If you go to Rotary Moe He has some awsome speed calcualtors, all java based, he did a pretty decent job of it as well.
