The Ford Barn - View Single Post - t-5 confused which one?

I'm too lazy right now to go through the math, but I know I've posted on this in the past to show RPM, rpm drop between shifts, and the differences between the combos of the common ratios.

Most '88-up will have the 3.76 1st gear if you're looking for that though.

EDIT: OK, I did a search and while I didn't find the exact thread I was looking for, here's one that will give you an idea of the rpm drop differences between what you're running now and what either T5 will give you. Of note, there's only about a 5mph difference between the gearsets in 1st gear.

My point? The purpose of a 5-spd is more about gear spacing - the overdrive is just a bonus. Why do you think all the performance cars of the 60s had 4-spds - more gears. Less RPM drop between shifts is really far better than the actual ratios.

If you're going to be picky, you should just have one of the several T5 companies build you a T5. That way, you can pick and choose the ratios and not be limited to the two available in the S10.
