Supra specific gear/diff ratio and tyre size calculator


Homer

Recommended Posts

I've put together an Excel file which shows the effect of fitting various sized diff and gearboxes to the supra, it also contains a graphical chart showing the effect different tyre & wheel sizes and offsets effect both fitment to the hub and the effect on speed/acceleration. There are two main sheets on the file, Wheel size fitment and gear ratio calculator.

 

I forgot to sticky this back when it was created last year, there's no updates to the calculator since the old thread

I cant get this to work on my laptop for some reason, doing my research for thunder road, can somebody put my details in and post a screen shot please, trying to work out my in gear speeds.

 

V160 and large TT6 diff

8200rpm limit

345/30/19 rear tyres.

 

8200 rev limit will do 255.52mph mate!:blink:

 

5th gear should see 202!

I got to beat 202mph standing mile to be the fastest supra in europe.

 

Oh, the bar has been raised again then! IIRC the 28 in wheels gave a good few mph more, about 207 in 5th? If you have the sizes I can post a plot with that, if you don't have the sizes I can work it out assuming they are exactly 28in tall.

Krister holds the record at the min.

 

They are 325/50/15 not sure 200mph on ET street radials is a good idea though.
