Thoes w/ UDP
Ok, I've read the sticky on the unothodox UDP and I was wondering a few things for thoes who run them. I also hear about pretty decent gains, mostly from the weight reduction and high tolorences they are contructed with.
1. Are you N/A or are you boosted?
2. in your opinion is it worth it?
3. noticable gains?
4. what other mods do you have?
Thanks for any feedback on this, and if I missed something similar to what I'm asking in the stickies, I appolgize.

1. They're n/a
2. No...unless you want bling bling
3. No
4. They have n/a bolt-ons...intake,y-pipe, etc.

1) I am NA
2) If you're all about performance mods...yes its worth it
3) Noticeable on a dyno chart......not from your foot or neck snapping back
4) Bolt ons
Dont listen to these *****......it's a good mod, kinda pricey...but IMO worth it. For every pound you take OFF the stock weight of the crank...you can gain about 2hp per pound. The stock pulley weighs close to 7 or 8 pounds....and the UDP weighs about 2½.
Combine that lightweight UDP with a lightweight flywheel......(kinda like I have...) and you'll have a total of ~13lbs off the crank. It revs a LOT faster and it will give gains...but its not like spraying or anything.

when i had my maxima it made response a lot better especially when it had all the breathing mods like ypipe, intake and exhaust. you won't feel the power, but you'll notice gains on your timeslip. i've seen gains up to a tenth. i would notice times would be consistently low 14.1-14.3 when i'd usually see 14.2-14.45 otherwise. get this mod last.

got mine from a group deal for 70 bucks with motorstorm. they pretty much copied the unorthodox's udp. so if you want to get them, might as well go with motorstorm for a huge deduction in price. got mine for 70 bucks. for that price, it's definitely worth the money.
after the install, i definitely feel the rev to climb up with ease. also, trap speed at the track is picked up by 2-3 mph's. but my lauches are bad, and clutch slips. so couldn't get improvements on qm times.
i got it installed for real cheap <30 bucks. so for the whole price, feel, and gain; i think it's a worthwhile mod. of course, there are going to be people saying the opposite, but i'm a guy who does every little mod to integrate a net power gain, so it's just part of the big picture...worth it: considering the amount of money i paid for my other mods.
also the underdriving electrical problems aren't issues with my car. i ran 1800 watt amp, 1 farad capacitor, and a solobaric L7 without a flicker in the headlights. so it's no biggie...
good luck.

i bought 2 udp's, one for my 5 speed, and one for my bro's auto, same year maximas.
on my 5 speed, the rev is felt much better than it did on the auto, but my brother claimed to see the ease of the rev on his auto. the pick up on the rpm range is very ideal for his taste. so...'sort of notice'=yes...
for a 5 speed, the response is very nice. the throttle awaits your foot...

I have a motostorm
love it , good mod for less than 100$ (70 for pulley and about 25~ for belts)
prolly didnt give me much power, but the tires seem to break loose more in first gear, and i can feel more pull above the 5k range
( cause i remeber my rpms would creep after 5k but now they seem to go faster)
its worth it if you put it on yourself, cause it would prolly cost about 100$ to put it on which would suck.
First buy exhaust and the other basics, then add the pulley as alittle something extra.

so the UDP gives gains..you just dont feel them.
so the pulley keeps accessories from slowing down the engine?
would this be something you'd consider taking off if you just wanted your car to be stock? like...is there any reason to ever switch back to stock after you upgrade this part?

If your looking to gain all you can from you car its worth it.
Its one of those mods that go hand in hand with others for a final effecting gain.
If you were to hold the UDP, and the stock pulley in each hand you would immedialty know that its benificial. The weight savings alone is a gain.
With the UDP, and my lightened flywheel, my car revs much quicker.

wouldnt there be a difference in opinions due to there being underdrive pulleys and lightwieght pulleys? wouldnt there be more varibles, which is casueing all these differant assumptions on whether it does anything or not.

Even a lightweight stock size pulley would give you gains. Whether you feel them or not is up in the air.

I don't understand where you guys are getting this stuff from. Underdrive pulley's don't add HP and they don't reduce times. To everyone that said they saw their 1/4 mile times drop, i'm willing to bet better conditions and a better 60' time are responsible.

You are correct, they DO NOT ADD horse power, they free up horse power.
Horse power that is lost from the crank spinning the heavier pulley is freed up with the lighter one.
The released horsepower gained from the lighter pulley could yeild better track times.

Adds, frees up, whatever. My point is this...practical gains > actual gains. Even if it frees up 3-5 horses (which i seriously doubt), no care. Because 1. That won't really show up at the track 2. It's within the realm of run-to-run dyno variance.

Dyno variances will effect any mod.
Like you said, the conditons will effect it.
Even if the dyno is indoors, weather controled there will still be variances, (ie, how long the car was run before the dyno.)
A dyno is used as a tunning device, and a gauge of power.
I have myself have dynoed my car on many occaisons, on different days and same mods on the same dyno and have had different numbers.
Even if it frees up 3-5 horses (which i seriously doubt), no care.
The ones trying to gain the most n.a. horse power do.
They have gone done to gutting the complete interior for just those reasons.

And just for everyone's info, being able to rev quicker in neutral does not even come close to necessarily meaning the same will be true once the transmission is in gear.

That guy DaveH, i believe said that he his times were worst with the udp, and he posted his timeslips with it, and without it
another guy on the org claimed, he nearly damaged his motor and it caused an oil leak, so he changed it back to stock and he was good
i know i dont have one, but i usually do alot of reading on something before i buy it, and if sacrificing my motor for 70 dollars is an option forget about it. if the 2lbs made a difference, why didnt nissan made it lighter in the first place?

this is one of those mods where ur better off finding things out for urself! half will say it works, half will say it doesn't, just as this thread has shown. and who knows, maybe it does do something to some and doesnt to others, i dont know. i havent installed mine yet so i really dont have an opinion yet, thats y im going to put it on soon. its only 70 bucks, if u dont like how it goes, just take it bak off and sell it for someone else to experiment. not sure with all, but with the motostorm u do need different sized belts.

Is this mod a yes or no? Well it's one of the best values dollar vs HP. I'd give motostorm a call and order one. Their everyday price is $109. Keep in mind you will need new belts, which will run you about $25-30 and a new crank shaft oil seal, which is less than $8 at most dealers (and should be in stock).
So grand total, $147--maybe some shipping in there.
If you don't have any mods, you might want to consider the basics, like a Y-pipe first.

I don't think half of the people would be making up that a pulley is giving them gains. Maybe if it was just one or two people, they might say it for bragging rights. The entire world can deny that it gives no gains, but my a$$ dyno says it does.

Ignorance is bliss i suppose. People really WANT TO believe it makes their car faster to justify the purchase. Like i said, if it doesn't show up at the dyno or track, it's not there.

alright all **** aside i personaly dont care what an udp does for anyones car i have a question
whats the major difference from an unorthodox udp and a cheap 60 dollar ebay one?
they appear to be the same shape size and weight.
a friend of mine put an ebay udp on his car and it did nothing
but then again people say the unorthodox one really does something good for you
