Hey dudes, gonna rally race my 1989 single cab, short bed 2WD 5 speed 2.3L Ford ranger that is super low to the ground in stock form which is what I am keeping the suspension as and I don't want to go with super tiny tires (for ground clearance)....
I have the 7.5" diff and 2.3L the shortest gear ratio I can find for the girl is 4.56, on 31's I would need like 6.0:1 to limit top speed of 110....
I really only need a top speed of 110 at like 4500 RPM, maybe a little more (if this 2.3L can even get me there....
My trans ratios are 3.72 / 2.20 / 1.50 / 1.00 / 0.79
So rapped out at 6000RPM on 31's we have a top speed in MPH of
(1st-5OD) 32mph,55,80,121,(@4500RPM 115)@6000RPM 153....
That seems sluggish in my opinion and I feel like I would be bouncing from
1st-3rd constantly to keep the rpm's up along with wheel speed/ tire spin....
Have any of you ever ran 31's with 4.56 gears and the 2.3? Is it as sluggish as I am thinking it will be? I was thinking if that is still too doggy maybe go down to a 27" tire like 255/60/r15 (27"/10"/r15) along with the 4.56:1 final ratio. Any thoughts?
