Re: Just Got Spanked...
More than likely it is the tall diff that isn't doing you any favours. When I Drag Raced my XB GT with a 2.75:1 diff (Old standard Engine) it pulled 15.8 @ 90 mph, compared to my EF XR6 which did 15.1 @ 89 mph. So as you can see, while the GT had more top end than the XR6, the 3.45:1 Diff got it off the line a hell of a lot quicker (probably a lot more than one car length off the line).
When I had the 2.75:1 Centre replaced with a 3.25:1, the Quarter Mile time dropped to 15.4 (still at 90 mph) so you can see the difference the change in diff ratio made.
