RPM Question?????????

[FestYboy]

^ very possible! i'll have to look into that...

[bhazard]

Perhaps its the same trans that was used in the earlier FWD Mazda's like the GLC, etc?

According to post 9 in the below link, there may be a difference in each gear ratio and the final drive ratio between 4 spds and 5 spds.

Jerry, that post needs to be corrected: the 4 spd listed in post 9 of that thread is the VERY early '88 4 speed manual that was replaced by the EM4-R posted higher in the thread. that alternate 4 speed (i've never seen a designation for it) was only put in Cali cars for the first 3 or so months of production. unfortunately everyone jumps all over that thread and goes "Look LOOK!!!!, it's right there!!" but they never check the 88/89 FSM...

If it helps, here's the relevant page from my '93 Kia owner's manual:

In real life what RPM are you turning at 60mph with the 4speed and stock tires 12" tires and what RPM are you turning at 60mph with the 5speed and stock tires 12" tires ??????
Thank you Bill

Thank you.Bill

most festys are 3.66 (iirc) and that oddball 4 speed is 3.8*

and Bert, final drive IS the same between 4 and 5 speed (final drive = pinion and ring gear ratio only, NOT the sum of the gear ratios)

what is the # like 4.30, 4.06 etc or what?????????

All the ratios are the same. Except some early 4 speeds supposedly have different gearing.

What is the final ratio on the festiva anyways????????

Bert, 4th in a 5 speed is the same as 4th in a 4 speed. Not necessarily true for all cars, but for Festivas thats is the case.

Wait a minute. I thought final drive ratio was the same for 4 and 5 speeds. Only difference is ability to accelerate on the way up there.

4 speed to 5 speed is huge on the highway... around town, very little difference.
