I got to test drive Radpp16's GLE after he installed it today... I have to say it feels alot better on the launch... Also the lag you get when you press the gas is gone.. The car jumps as soon as you hit the gas and the rpm revs much faster.. I was thinking of getting the VB recalibrated but now this is definiately gonna be my next mod no doubt!!!...

maxse01

I was thinking about it, but i heard that it messes the alternator, water pump, power steering etc. If all his systems seem uneffected i will consider it more seriously. Please advise. Thanks

RBA- was the UDP a simple install?

It is if you get sent the right belts the first time.

And the right tools too!!!!!!

And the right amount of patience...I heard the usual crap from the dealer about the power steering, water pump, and alternator, but I have yet to see any difference in any of those systems. I imagine if you have a 1000-watt stereo or something to that effect you could have problems, but the amount of power you'd need would have to be up there. I felt a nice difference in mine too all over the rpm range, and it definitely helps to make up for the loss in low end if you have the intake-y-pipe combo.

Is there any noise added?
BTW: WHo wants to help me out with the UDP install, I live in queens?

it was worth the 6 hours. now im thinking of getting one. if your auto felt like that, wonder how my 5speed will do

clee130

Wait ... didn't you say, "I honestly don't feel anything."

ToYLeT902

well i've driven automatics before, so i know that lag you people talk about. but when the udp goes in, once you touch the gas pedal it goes, no lag. but hopefully it'll free up some hp on my car. maybe i can chirp into 3rd

In my experience, the UDP is a pretty good mod to do if you already have intake and y-pipe. After the UDP, I noticed that the car was more free revving and the lag in getting up ang going was gone. The revs climb quicker especially at lower rpms and I can spin my wheels from a dead stop a little longer In first gear I can get to 5k rpms from a dead stop a lot faster than before. Overall, the performance gain from the UDP is not extremely dramatic, but it is quite noticeable

This thread seems to contradict other posts that say that UDP does not provide any noticable benefits. Someone even posted dyno charts that show lower HP after UDP install.

woosh

I remember seeing an advised order of mods somewhere on here but couldn't find it. What mod should I have before considering the UDP? I don't have a Y-pipe?

UMD_MaxSE

iTrader: (1)

here is my suggested order:

Performance
1. Intake
2. Y-pipe
3. UDP
4. RT cat and cat-back
5. Nitrous/SC/etc... (can't use UDP with SC)

Suspension
1. RSB and FSTB
2. Springs and struts
3. Motor mounts

Of course, there is the tranny also, so that goes somewhere in there

clee130

The UDP frees up horsepower that is already there. Or something like that.

ToYLeT902

yup

2001SilverSeMax

What brand of UDP do you guys have and how much were they?

If you hurry, you can jump on the group deal by yoitsok. Check the group deals section. $190 plus shipping I believe.

a 5th gen here had a loss on the dyno after the pully install? From that thread most agreed the pulley wasn't worth it for 5th gens??

Pmp-n8a

you can still install a UDP if you have a turbo right??

irvine78

iTrader: (2)

now who would say such ridiculous things? i heard many saying about how the UDP affects your A/C and the power steering...in my case, no problems for the A/C, but the power steering requires little bit more input to turn the wheels at low speeds...but i like it this way better...my car ain't a Towncar anywayz..

Or maybe your car sucked in the first place.

Invasion from 4th gen area. I installed the UDP like 2 months ago, and had no troubles (yeah, the steering is a little stiffer at low speeds, but I like that too). As far as the water pump and alternator go...well...consider this. The load that that pulley had to turn is lighter now, not heavier...as long as the belts are the right tension, you should be fine. It's not like a SET of pulleys either, just the one...isn't a big problem IMO, and lots of people on this board have had them for many miles.

I notice a wider powerband and more low-end power. Now I just need my y and cat-back....

Pmp-n8a

anyone know if you can still use the unorthodox UDP with a turbocharger???

ToYLeT902

iTrader: (12)

i kno you cant with a sc.

ru4real

iTrader: (3)

Why not? The size of the crankshaft pulley doesn't affect a turbo like it would a supercharger. Since the UDP allows your engine to build revs quicker, I think it would benefit the turbocharger.

Pmp-n8a

just making sure

Is there anyway to makeup the loss of power to steering, a/c etc.etc.

friend of mine mentioned a different kind of car battery but i was skeptical about that

UMD_MaxSE

iTrader: (1)

there is no notcieable difference in steering, AC, etc... unless you have a 500 W system, you will be just fine
