i have a 2000 usdm R no transmission mods, with 15s on 50 series tires. When i first got the car i swear that 40 mph in 5th gear was about 2200 rpm, i am currently reading 40 mph at 2000 even. Can any one hop in their R real quick and confirm 40 mph in 5th gear = xxxx rpm. Thanks. B

that should work thanks.

 

In fifth gear, 75 mph = 4000 RPM.

 

And even driving to work everyday at that speed, we get pretty good mileage. Not many cars offer a race car feel and give you nearly 30mpg's!

 

ITR wins again

 

ITR always wins GO R!

 

Thanks guys my speedo was off, swapped the unit from another cluster.
