EA tranny speed table


Recommended Posts

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.

says the brat will be turning 15,425 rpm in 1st low at 60mph. weeeeeeeeeeeeeeeeeeeeee:banana: kaboom

 

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
