Crank underdrive pulley for 1991 2.3?

zonker · September 21st, 2010, 08:39 PM

I've seen ones that have single or double v belt configs but none for a serpentine belt equipped 2.3 mustang.

Any ideas?

2.3 Ford Underdrive Pulley Set

great pull - thanks!!

since i have a double serp pulley on the water pump, i think i'm out of luck using the wp pulley in the kit speedway shows.

are you familiar with this udp?

do you know what the crank pulley diameters is compared to stock?

i'm thinking i need to keep the underdrive in the 25 % range since this is a daily driver.

i found one more concession i'd need to make to run that udp... i'll lose the a/c compressor pulley on both crank and water pump.

hmmm - this is one more reason for pulling the a/c compressor and all the hardware

UPDATE - it looks like if i run the crank pulley only and run a shorter ac belt to wp/ac/tensioner i can have my cake and eat it too

UPDATE AGAIN!

LOL

Just got off the phone with my man at Esslinger and it turns out they have a street style udp for the serpentine equipped 2.3's, and since I'm already a distributor selling their zetec parts well... I got a killer deal (for esslinger prices that is).

I should have the udp tomorrow and i'll be trying it out this week. I fully expect to see similar gains as i do with the essy udp on a 2.0 zetec... about 8-10hp.

keep your fingers crossed, this might be the best simple bolt on bang for the buck for the 2.3.

Pictures? Would like to see how it looks? And definately need to know if there is a power gain like there is with V-8's ...

I'll take some once it's here - it should be here tomorrow (they're 80 miles away from me so ups service is next day).

I know on the zetec it's enough to be a seat of the pants feel, so I'm hoping much of the same. I'll probably do the install this weekend.
