underdrive pullys??
#2
It's not that bad to install..take off the rt front tire and then the fender well and there it is..then loosen up the belt..just have a breaker bar w/ you to get it off...it doesn't add horsepower,it frees it up buy having that lighter pulley..as far as noticable gains, well you will have to dyno it and see but i could guess maybe you will free up ?3-5hp?. Some people may say differently though. Happy Modding!!

Does the Max have a harmonic balancer on the OEM pullley ? im pretty sure UPP doesnt have one on thiers.
(My pasted car was a Altima and I had the UPP pulley without a harmonic balancer.)
Has any Maxima have any problems with this or is an issue? Just curious before I start going modd crazy. thanks

The udp releases about 5-10 hp depending on the company, and the weight of the udp. Also expect quicker revs to the redline. I have DMS one, I thinks the weight is 1.24 pounds or so. And no, aftermarket udp don't have harmonic balancer's.

Has the Maximas onwers or tunners ever occur this problem or have they brought this up as in issue or is it pretty much safe?
I was running a UPP afterwards boosting the KA24DE(T) even tho they said the underdrive pulley wasnt nesscary for a boosted car. I still manage to use it.
So I guess my Question is has this ever been an issue with the VQ motors?
I just like to know what im getting into since the VQ is a new motor for me.Since Ive been tearing and building the KAs for the past 10 years. Thanks

I added a UR UDP pulley about 6-7 months ago. No issues and the most noticeable improvement in my situation is no more drag on the engine when the the A/C is on and the compressor kicks on/off. So during the hot and muggy Florida summer where the A/C is a must, the butt dyno tells me it frees up about 5-7 ponnies. But I do agree that it is better used it conjunction with other mods.

But some people have said that the timing ring that's on the pulley itself can loosen, and cause alot of damage. That will be only for the vq30 peolpe. The 3.5 motor doesn't have a timing ring, so no problem there.
anyways I guess Imma go with a underdrive pulley from Pro-1 Top Speed instead of the pricey UPP ..Arospeed also now makes a pulley for the maxis
Im a authorized dealer for Both Top Speed Pro-1 and Arospeed.
Altho I guess I will be the gunia pig for those pulleys.
