Anyone looking for an expensive durable UDP? I had some made for the 3rd Gen VG guys a few years back....I'll more than likely go that some route with my 98 Maxima....Anyone else interested estimate cost is under $200....IIRC the cost was about $150-$185.....

 

UR already makes one for the 4th gen.

And an underdrive pulley is nearly worthless anyway. $185 for a couple of hp, not to mention the negative aspect of having an underdrive pulley...no thanks.

 

Passing on this.

 

I am going to pass also

 

Nope.

 

yeah I thought they weren't available anymore.....But they were well over $200 per unit anyway.....these will be less made by ASP racing....

 

Sorry, not worth it.

 

For the cost and aggrecation for very minimal gains its not worth it to most, dont take it to heart but an udp is more a pain than its worth...its kind of one of those things people buy just to say they have one...

 

For that price might as well get intake spacers just sayin......

 

Hold out your hand and I'll give you an OEM and a Billet aluminum crank pulley....Maybe they can't measure the benefit with their a$$ but I'm positively assured there's plenty of benefits from it just reducing the weight on the crank alone.....

 

Gains are very minimal.

 

The extra 2HP is not worth an undercharged battery or warm AC. If you had a stock diameter lightweight aluminum pulley made, well then you might have buyers.

 

That already exists too, well kind of. I worked with UR years ago and they made me and Ptatohed stock diameter lightweight aluminum pulleys. Not sure if it's available to the masses though as it's not on their website.

 

they beat the crap out of your engine.
no thanks

 

That was done for the VG Sohc 3rd gen as well, we made an UDP and an OEM lightweight crank pulley....I've been running a UR UDP (on my 03 VQ35DE) for 8 yrs and I've had an ice cold A/C and with an Optima redtop no problems (audio guys have problems with UDP's)... I've even been running the same belts since I installed the UR UDP....But no biggie guys I'll have some made and those that want one will have a chance to buy one!

 

WTF are you talking about! Our engines are internally balanced....This isn't a Detroit engine with a matched harmonic balancer! My 03 VQ35 and running smooth and strong and it's had a UR UDP for 8 yrs.....130K+ miles.....

 

Internally balanced or not you cannot convince me. they are not stock and do not dampen the vibration engineers are not stupid

 

at all of the unproven claims in this thread, this is why I take what people think/say on the .org w/ a grain of salt.

Anyways, I will text you Cmax, I just saw the prices on a UDP and got shocked, I definitely want to put one on my white car too.

 

Harmonic balancer is a bit of a misnomer. A harmonic damper is used to dissipate the harmonic oscillations caused by torque loading imposed on the crankshaft during the power stroke of each cylinder. If you look at the VQ30 balancer (damper) you will see it is two piece, bonded with an elastomer band. Replacing the the stock damper with one piece part could (not will) result in stress cracks and eventual separation at the oil galley or fillet areas of the cranckshaft. Use at your own risk.
I will say that the VQ has proven itself in longevity and brute strength. If any engine could live without a harmonic damper, it would be this one.

 

+1 to me it's not worth the money or risk for 2hp

 

No biggie guys I'll do 1 UDP and 1 OEM.......

 

Too much negativity in this thread. If you make a stock size pulley then im in.

 

^^^ what he said

 

I'm gonna make both sizes...UD and OEM...ASP Racing estimates $125-$150 per unit!
Here's 3rd Gen VG SOHC they made for me b4:

Here's mine 1990 Maxima's VG30E (UR UDP)


Both OEM sized and UDP


OEM and Lightweight Oem sized Billet

 

I was actually looking for an OEM size pulley. Id be interested

 

So right Now the list of those interested is like this:

OEM Sized LWP(lightweight pulley)
1. IslandMax
2. Wirelessdude04
3.CMax03
4. Aackshun

 

I need a crank pulley, is this the LWP going forward.

 

GL with this I had a Ralco on my 03 for like 9 months no problem at all with AC or battery issues but ride got totaled, now on 02 got a Motorstorm one....

 

5. ABIGBRAIN

 

Any update on this?

 

Yall ready to do this? I'll send them a pulley to copy into there cad database this week?
1. IslandMax
2. Wirelessdude04
3. Cmax03
4. Aackshun
5. ABIGBRAIN
6. dgoodhue

 

Im in.

 

We can do both UDP and Lightweight OEM...I'll more than likely go the OEM size route or do both like I did for my 3rd Gen! I'll shipping them the Oem model to Copy into their CAD database b4 this weekend guys.....
