I just finished this table and put it into the USRM.

It's a table to help you determine your top speed taking into account tire size, tranny and hi-lo ratios.

at the top of the tables you can enter your desired tire size. Then go to the table that applies to the tranny that you have or want to have.

so for my RX with 205/60/13's I have a theoretical top speed of 140 mph at 6685 rpms. Doubt I would ever rev it that fast...

Enjoy.

no, those figures are for a 205/60/16 tire. That is what is on my BRAT.

remember you have to change the numbers up to your tire size.

Yeah.... obviously you wouldn't be doing that.

bolt the EA81 tranny to an F1 engine and it might work.....

In terms of numbers, the table helps to explain why I was able to drive the EJ18 BRAT w/a 4spd d/r tranny with 205/60/16 tires on the freeway traffic mostly in 4 gear low.

20 mph 1148 rpm
30 mph 1721 rpm
40 mph 2295 rpm
50 mpg 2869 rpm
60 mph 3443 rpm
70 mph 4017 rpm
80 mph 4590 rpm
