maximize shift points

Not exactly, with the 200R4 OD trans 2.74 1st, 1.57 2nd, 1.00 3rd & .67 4th. it has approx. 2% more drop @ the 1-2 and 5% more on the 2-3 then the 904. Not overly huge, I get your point. I suppose I was being a little picky between the two. Just looking at any advantage/disadvantage I could find.


The 700's 3.06 1st to 1.63 2nd is huge though.
I love these wide ratio transmissions for the street daily driver, but i'd truly prefer the closest ratios I could get on a drag strip.

so between a .8OD and .7OD is 300 rpm, so 300 x .1 (10%) is 30rpm per .01 (.01 because its 10% of the above OD's split). so your looking at 60 rpm difference between a 1.57 and 1.54, pretty much nothing... all in all it has an OD, very close ratios to a 904...

and the 700 is just wack lol
