Underdrive Pulley, is it worth it??
hey fellas,
I just had my Stillen intake un-installed from my 2000 maxima because i lost the quiet and smoothness of the ride. I have any underdrive pulley but i'm wondering what kind of "side effects" i guess you can say, will i have if i install the pulley. I would hate to install it then take it out because i didn't like it.
So if you guys have any advice, experience or suggestions i really would appreciate it!
thanks

It depends what you mean by "worth it". It is worth it if you are looking for every little bit of power out of your Maxima. I would estimate that it would only give you about a tenth or two off your 1/4 mile. But, since I don't know too much about 2000 Maxima's with UDP's, then I can't really answer your question.
I have a 92 SE Auto with an UDP and it shaved off about .15 off my 1/4 mile. It's really hard to notice with a butt dyno. But, you will notice that your tach moves quicker. Also, you might notice that you gain a little low end power. I would chirp my tires when I never use to. So, I say my UDP mod was worth it b/c every little bit helps. But, I know that this is a mod you will notice. Just don't expect too much from it.

you guys can argue all you want about this.
blah blah not worth it. blah blah hurts your car.
freakin half of those who argue against the UDP dont even know what a UDP is let alone ever been near one, nor installed one. ( i might add this similiarity to the Gforce ECU)
its a good modification bar none.
lets the engine rev faster, while sacrificing a little on the power steering but the steering needs to be less sensitive anyway.
A GOOD 5 speed mod, semi noticable on an Auto.
the install is meant for pro or high skilled DIYer with the right tools. theres many things u'll need to do to install it right but baby, once its in, you'll know its there.
alas. u know where i stand. Knowledge is power... everyone should do things on what they want to do. not what some chump says. .. if i'm a chump here. then so be it. but i got a reputation and a web site to uphold....

Cheston, it could be a good mod but the gentleman is asking whether its worth it, especially for the cost. The pulley does something but not enough for what these guys are expecting from it.

Will you feel the difference? Of course. Is the difference like a Y-pipe? Of course not.

Definately get the y-pipe, some sort of modified intake, and B-pipe/catback first. Many will argue that the UDP does very little siimply because we have little dyno data supporting that it works. I respect Sprint's and Medisonic's opinion that the UDP doesn't work, but I feel that they are wrong. There are only two people (one 5th gen, one 4th gen) on this org that have dyno tested the UDPs. The 5th gen showed little if any gain, but the car wass never track tested. The 4th gen showed a gain of 5fwhp, but was never track tested. I plan on redynoing my 96 5 speed (y-pipe, intake, b-pipe, UDP) as soon as a get a replacement muffler (mine's rusted out). My current dyno without the UDP is 176fwhp/194fwtq. I'm hoping for 180fwhp/200fwtq. I have track tested my UDP and I've found my car to be a bit faster thru the 1/4 mile. Without the UDP, my best trap speed was 94.0X mph. With the UDP, I've hit 95.5mph. I have consistently been quicker and faster overall with the UDP, but I still haven't beat my best with the addition of the UDP. My best without the UDP was a 14.73@93.93mph in 45 degree weather. My best with the UDP is a 14.75@95.08mph in 75 degree weather. As you can see, my car is only 0.02 seconds slower, but over 1mph faster even though I was running in 30 degree warmer weather. It's fairly accepted that you gain ~2% power for every 10-12 degree drop in temp.
The biggest advantage of the UDP is it's lighter rotational weight. It is also 20% underdrive which helps a little too. I think the biggest gain in the UDP is felt in gears 1 and 2. I have yet to ride in or drive another Maxima that feels remotely as strong as my Maxima does. UDPs have been shown to gain power Mustangs, F-Bodies, Vettes, Sentras, Neons, 300ZX, Focus' (Foci?), etc. I don't see why the Maxima would be any different.
It's up to you if you think the UDP is worth it. My timeslips clearly show me that it's worth it.

Reasons I got the UDP:
1) It was offered to me by someone I trusted for a good price at the right time.
2) I was planning to also buy a Y-pipe and exhaust at the time, but some other things prevented that. It was going to be a group of things done at the same time.
3) I knew it would help me, even a little, in the low end, and that's where I need the most power.
If you recall, I sort of LOST MY JOB, so monetary issues prevented me from getting the Y/exhaust. Then all the bad things started happening to the car, expensive things, so I haven't had the money to complete the picture. However, I am probably getting rid of the car soon, so it's a moot point.

Body kits are for looks. UDP was for 'that last bit of power'. If you didn't have the money, you should have sold it at a profit. You didn't. Now, my car is WAY faster than yours.

Again. I DON'T HAVE THE NOS IN THE CAR... And I wil soundly ROMP on your car. Without a doubt.

2nd gear I can appreciate, but then that means the benefit to the UDP is mostly in 1 gear. I would think it affects all gears, just more subtle as you go higher up.

The problem is not my tires. I've had Pirelli 7000s and now I'm on Kumhos 712s. 225/45/17s. Do you drive an automatic Maxima?

The UDP is last but not least, a good mod! I have a 5-spd with pretty much all N/A bolt on's. I like this mod and is worth it. However.... like almost all mods, you'll get used to it. No neck breaking performance but noticeable.

it seems that this argument keeps going on and on...but from reading everybody's replies...it seems that if you want to get as much out of the VQ engine as possible...every little mod will count. Although there really hasn't been any proven GAINS in HP, the engine revs up quicker...so, get it or don't get it? Get it if you have nothing else to purchase for your engine...
