so my instructer handed me a tracer the other day (one of those tracers people use to see if their wife is cheating on them) and it tells location, time, destination, speed, etc.. anyways, he told me that the record on it is 133mph, so i told him that if i dont break 160 that he can fail me.
on sept 1 i take the evo out and hit 170 @ 7500 rpm..
on tuesday when i went into school the tracer was plugged into the computer and it said that my top speed was only 154mph...
now i know that the speedo can be off after 120 or so because it's only a magnetic pickup, so eventually it'll be off by 5 mph MAYBE 10.. but 16mph? that seems a little off...
so to do the math on what the evo's final drive is geared to do, i need to know 5TH GEAR RATIO AND REAR DIFF RATIO..
if anybody could please help me it would be appreciated, and i will let you guys know what the top speed is according to these two ratios and rpm.. thank you!!!!
