It tachs high now but the difference is great when you smash the gas. The 3650's have a better cruising (5th) gear ratio, so 4.10's in them wont tach as high in 5th as compared to a T-45 car.

Your top speed would probably be 135+, give or take 5-10mph. Watch this video... http://www.justagt2.com/movies/gearmovies/gears9.AVI That's with 4.10's!
