What is the top speed of your SG or RG; if you've had the opportunity to check it via the dyno or GPS? Mine was 126.3 in 5th gear and 150.1 in 6th gear on the dyno. I never would have thought that these motors were capable of producing those kind of numbers, but it sure is nice to know. Please let us know what mods you had when you checked your top speed. Mine are in my sig. Thanks
