anyone with a stock 3.0L... help

[1993MTXSHO]

Woulda anyone be kinda enough to measure there stock 3.0L ps pump, alt. and waterpump pulley diameters for me?

off my 91-
W/P- 4 1/2''
Alt.- 2 5/8''

I don't have a spare p/s pulley though.. But I do know that the ATX is slightly bigger. I wanna say 6 1/4'' .... but don't qoute me on the P/S.

Kinda makes me want to pull my old SS UDP's off to see how big the reduction is now.

EDIT: the measurments were taken on spares (off of the car). So the measurements are almost spot on. just FYI.

sweet thanks man, anyone have the ps pump?

EDIT: old SS pulleys were 15% reduction IIRC

and the atx pully i have that i plan on using as an underdrive is 6 1/2"

with UDP what pulleys are replaced? is it all 3? or just 2. I seem to have an UD alt pulley at 3.2" but a stock wp pully. I was told i had shoshop UDP's on my car when i bought it.

EDIT: My ps pump pully is 5 3/4"

noone knows the diameter of the stock ps pump pulley?

I can get it when I get home. I have one hanging on the wall (it was bad so I had to punish it!). ~ 1800 PST

 

[1993MTXSHO]

haha, ok sweet, if you can post that tonight thad be cool

 

[Devin]

5 25/32" (margin of error: 1/32).

So more than likely it's either 5 6/8s or 5 13/16s

 

[1993MTXSHO]

ok and i measured mine to be the same so mine is stock, the guy i got the car from said it had UDP, i guess he ment one stupid pulley on the alternator.

FYI the ATX pully won't work on the MTX. the engine damper bracket is in the way. I had the same idea but it dosen't work unless you remove the roll dampers then it might, but I wanted to leave them so i just put the MTX pully back on.

 

[SASHO91]

Oh, well mine are removed. Should have noted that. I've tried the ATX pulley on the car and it fit fine. (Just forgot the belt... )

the atx pulley is only about a 10% reduction and weighs a hella lot more if im not mistaken. So its really not worth it anyway.
