s'ko Posted July 22, 2008 Share Posted July 22, 2008 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. http://www.ultimatesubaru.org/forum/showthread.php?t=90609 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. BW Quote Link to comment Share on other sites More sharing options...
ahole Posted July 22, 2008 Share Posted July 22, 2008 I guess my wagon will do a solid 160. Quote Link to comment Share on other sites More sharing options...
s'ko Posted July 22, 2008 Author Share Posted July 22, 2008 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. BW Quote Link to comment Share on other sites More sharing options...

s'ko Posted July 22, 2008 Author Share Posted July 22, 2008 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 Quote Link to comment Share on other sites More sharing options...
