Acceleration difference between 3.91 and 4.30

Whizbang · 02-13-2009, 12:35 AM

im just curious what the 0-60 difference would really be between the 3.91 and a 4.30 (say in a convertible with a manual transmission). I can figure calculations on this and that , but does anyone have any more real numbers?

probably could have had this in the transmission section...

In my first gen I ran 9.70 in the 1/8 mile with 3.9 and open diff. I ran 9.16 with 4.3 and a torsen. I think I gained 4-5 mph as well.

impressive difference for a simple modification. FB is lighter than the vert by quite a bit, but still.

I noticed a difference from my GXL with the 4.10 and my GTUs with the 4.30. It's not HUGE, but its noticeable.

its noticeable in first gear compared to my old fc which had a 4.10 and my current 3.90.
