OK heres the deal. My belts are going to need replacement soon. They're very shiny and are squealing. So that's gonna have to be done. Here's my question. I have an auto. Would it be worth it to put a UDP on the car since I'm changing the belts anyway? Anyone besides SprintMax is free to respond Thanks.

 

As long as u dont have a high power stereo, which you dont. Get it.
PS- Take off that trailer hitch!

 

well from what ive been told, a system will not effect the motor or alternator if you just have an UnderDrive Pulley. Its when you do the Alternator pulley is where youll have probs(civics, VW's,etc..). And since UR only makes a UPD for us as of now, you should be fine.

Doesnt the UDP take away power from your system, if you have one?

 

Not for Maximas.

WOW...I always thought this would take away power from my subs, I might get one also.

 

ya, i was hanging out with some max peepz last night, and i wanna UDP pulley so bad now...my friend was telling me its not good, bla bla bla, makes the engine work harder....anything like that true....i dont have a system, dont plan on getting one either....what are the benefits of the UDP (besides telling me to search, but if you gimme links, )

 

UDP free HP used to turn your pulleys for A/C and other essential features allowing the car to run proper. UDP are usually less weight therefore allowing your car to have more effieciecy. All in all, you most likely will not notice the benefits unless you get a lighter flywheel. That's just what I have noticed. Might be different for others.

don't make the same mistake i did. do the UDP last, right now i am hyped about the "VB mod". have you used this mod?

 

What is this VB mod I have heard about?!

 

valve body mod....search button top right help you out on this

not true one bit. i have an udp on my auto and 1500 watt alpine w/2infinity perfects. doesnt affect it. actually if you think about it, it is making your alternator spin faster. more amps maybe if anything....

 

did you notice a real difference with it, or is it all mental? lol

Ant

 

revs up faster, which in turn makes your car quicker,......maybe b/c i got the blue one ..but i also have y-pipe,carsound cat,PR cai if any of this matters

 

UDP only helps to quicken throttle response & acceleration by reducing the spun mass of the engine. It is doubtful that it actually save hp by taking it away from the accessories.
When drag racing, you turn off AC and all unnecessary electrical devices anyways and you don't use steering much as to put large load the PS pump.
A light weight pully with no underdriving will be just as effective. Or light weight flywheel as noted earlier.

 

i belive stock was like 5 pounds and udp was like 1.something. BIG difference.

 

On the other hand, heavier pulley and flywheel does help smooth out the engine, less vibrations and surges.

 

well thats just a price to pay , but i havent noticed any of this. not tryin to scare anybody out of this mod but mine has been on for about 8 months and no problems what-so-ever. and yes stereo was in all of this time also.
