So Mooneggs asked what MPH I was at @ 4,000 RPM because he wondered what the difference was between my K8 tranny, and his 626 is. Mine is at 79, and his is at 82. Maybe our speedos are off, or something. We both have stock 15" wheels. So, what's your speed at 4K, and what gears do you have?

At 4k im in the 80s. I have a PGT trans

at 4000 i'm at 120kph...73mph on stock K8 tranny.

edit: On the way into work this morning I checked and it's closer to 78-79mph than previously stated.

before i messed up my guages, i was doin 130-135 at 4000rpm...not sure if my 17's were throwin it off, but i normaly cruise the highway at 3000rpm steady at 120 thats with k8 auto trans

Pgt trans and MX3 trans are the exact same.

maybe your pgt got an mx6 trans.

this is just like my k8 is as well...

Ah, you may be right I forgot I put a new tranny in my probe last summer with the ze. It might be out of something newer.

mine too

No matter if you have a K8, KF or KL, your RPM's will not change because of the motor. It'll change cause you've either got a different ratio tranny, or you've changed the size of your tires

Mx-3 & Probe : 4.38:1
626 & Mx-6: 4.11:1

Myself, with my K8 tranny, regardless of K8 or ZE motor, i do about 120km/h @ 4000rpms

are those ratios the same for 5spd and automatic..?

Nope

VERY well said!

Anyone else with 4.11:1 gears?

i do 120 at 4000k ze engine k8 tranny. so the big difference is about 10-15km/h.
i am currently looking for a 626/mx-6 tranny.

With a stock tranny I was doing about 120kph@4000
with 4:11 approx 140kph@4000 (swapped 06/1997 with engine)
with 0.69 5gear swap almost 160kph@4000 (swapped in 1998)

BTW My cars been off the road and in storage since 2001 with a blown tranny.
