So I know this has been long a waited for and now here it is. I picked up the pulley last friday, but I was doing brake upgrades so I took today off work/school today to install the new UDP.

First off I have to say that I was very VEERY upset with Joe from UR, b/c when I went to remove the bolt on the pulley (which they had previously removed and taken dimensions from) I found the bolt was WAY over torqued (I kinda expected this b/c all the belts were over tightened). I recently picked up a Ingersol Rand 'Thunder gun' impact wrench, which has a max reverse torque of 650, and yes even at the highest setting on the impact wrench the bolt did not come off. I called him up and pretty much blew my top off. I was able to eventually get the bolt off after raising the air pressure to 120psi (its only supposed to be 90psi or slightly higher). So he gave me this big BS story where he claims they did not use an impact wrench to install the pulley and he said they used a torque wrench to install the bolt. So I asked him how is this possible the bolt would simply turn the crank, so he replied that THEY PUT THE CAR IN GEAR, I was like AAAHHHH and I was like I have an automatic, he was like oh well yeah so then I removed the inspection plate and did something to lock the pulley against the bell housing (I had no idea what he was talking about!!!!!!!!!!!). I think he was F-ing lieing to me.

Well anyway there was no signs of damage to the bolt threads, so the crank shaft threads were probably not messed up.

Okay now that I'm done venting (but still very ****ed).

I took a lot of mesurements of the new pulley and compared them to the stock. All of the critical specs for proper fitment were done very well. They said they would underdrive the pullies 20% and they were right on the numbers, the water pump/power steering pulley is underdriven 22% and the other two pullies are underdriven 20%. I did not weigh the pulley but it is less than 2 pounds. Getting the proper belt lengths was quite a task b/c there is very little room for error, two of the belt are perfect fits (length wise) but the power sterring/water pump belt was kind of a compromise length, but is acceptable for know.


Alternator 315K5 (31 and 1/2 inches with 5 ribs)
Compressor 445K4
Power steering/WP 378K4 (that means 37.8 inches with 4 ribs, but the belt needs to be slighly shorter maybe a 37.5 would be better but that size was not available from the three stores that I visited).

Okay now to the fun stuff. I tried to take it easy at first but found myself going at WOT every chance I had. From a stand still the car accelerates very effortlessly. When gunning ir from a stop I get a good amount of chirping. This weekend I'll be hitting the track and running with a 5spd 92se from the org (MAX420) I'll be installing a UDP (but from ASP racing) in his car the same day that we will go to the track (no we wont be comparing the performance of the two UDP's b/c they will be pretty much the same) The only slight differences of the pullies will be the quality of the materials and the weight of them.

If I had the chance to do it all over again I would have bought the pulley from ASP for the 100 bucks. The only thing I gain from doing the development with UR is I'll get the first production one for free and a couple engine dyno's to see how much power the pulley release from my engine.

 

Would you say that the UDP was a worthwhile mod? I bought mine over a month ago and haven't installed it yet. I'm still looking for an org member to help me install it. I'd rather not pay a mechanic $150 to do it since it seems like a straightforward install.

How long did it take you to install it?

 

Ahaha sweet man, Cant wait till my udp is on....and damn still waiting for WSP to send the me the friggin' y pipe..... 3 weeks and counting...

 

sorry about your bad luck...keep us posted on how the dyno's go and such

 

Yeah I'm looking to get this over with. But the car runs great, I dont think there is much need for the computer to make any great adjustments.

I'd say the UDP is worthwhile, but we'll see how much UR wants for it. I mean anyone with a ASP UDP, should'nt get ride of theirs to get a UR UDP, you simply wont notice any difference. You need an impact wrench to get the pulley bolt off, if you have one then its a simple job. Remove the belts, remove the tire, then remove the pulley.



Adreis, the weather looks better for saturday, they say it will be almost 10 degrees cooler than Sunday. It's probably better that we dont run at the track when 'funny cars' are running, they'll probably be crowded. So how does saturday sound?

I'm painting my Y-pipe before installing it, I picked up spray paint from Duplicolor and it good up to 1200 degrees farenheit (black). So that salt doesnt mess it up during winter months. Which pipe did you get from Warpspeed.

 

Sweet, The paint should help it out a lot. I bought the SS y pipe, stilling waiting on it to arrive so I can get it on. Oh and Saturday sounds good, but I don't think I can make it to the track, my wheel bearing is making horrible noises and don't want to risk anything going to the track, . I'll let you know how it goes. I want to get the UDP on, fix the bearings then head out to the track after receiving the Y-pipe. How does that sound?

 

U suuck dude
I'd help you with the wheel bearing, but its a pain in the **** to get the hub off. Then take it to a shop to press a new bearing and seals in place. Which wheel is it, drivers or passengers?

I guess we can put the track on hold.

Eric,

Are any future VE oil samples planned in the near future?

Yeah I'll hook you up bill, I've got cash flow
