whats the difference between the 2

 

I remember reading that the RVM was causing oil leaks. Be safe and buy the Unorthodox.

 

I'm not too sure about the RVM pulley's but our customers have been pretty happy with the UR UDP.. We do have these pulleys in stock as well, so if you're interested feel free to give me a call or email me and I'll get you my best price for it.

 

The RVM cost less and causes oil leaks and the UR is more expensive and works just fine.

 

dont buy either one....i dont know if its just me but i just installed it on my 2001 auto and it did absolutly nothing...i noticed nothing....the timing advance was better then the pulley and it was free....i bought the unorthodox as well....

 

I installed the UR 2 weeks ago and like it. Sorry no dyno yet, later. I spoke to UR and asked the difference in theirs VS. others. They were unaware other people had made any(RVM). I told him I believe the bushing was bronze, as opposed to their SS. He said bronze was softer than SS and would wear out faster, as I assumed myself. If you look at the crank bushing, it is actually hard rubber with an inner spring that runs tight against the pully. I went UR because they have been doing this for a while and spinning something like that at 5-6K RPM I would prefer the time tested company. so it is your personal choice, but a one time purchase for me, UR was the safer bet.

Good luck!

 

Actually RVM has no bushing and the Definitive Motorsports UDP has the bronze one. Nick from DM claims the bronze bushing is better in this application than the steel one. Also the DM UDP is a little lighter and about $40+ less expensive than the UR pulley. So far no one that I know of has had any problems with the DM pulley.

I was wondering when the RVM in the title would lure you in.

 

I've been too busy to spend much time in the Forum lately. But it was only a matter of time before I caught up with this thread.

I just took my car in to have it serviced. I haven't developed an oil leak with my RVM pulley yet. But I've got less than 3000 miles on it so far. Meanwhile, my UR UDP is up on a shelf staying nice and cozy in its original factory packaging. If I need it, I'll use it. If I don't, I'll dispose of it when I sell my Maxima.

 

Timing Advanced (17 Degrees BTDC).



Im know Im going a little off topic here but what is the stock timing at? 15 degrees??

 

Sorry my bad, but at least I have the info now.
UR bushing= Stainless steel
DM=Bronze
RVM=Aluminum ,because there is none?

Lets see, spinning at 4000rpm, against a tightened spring seal made of a tough plastic. My guess is it would wear the AL down and thus leak. If not does anyone know if AL expands more than SS? Because if the Al heats up it is expanding, and causing damage to the seal and then when it cools it leaves a gap and thus a leak.

Glad I went the Unorthodox way.


Vroomm!

 

Normally it's set at 15 degrees. But it can be set plus or minus 2 degrees (i.e., 13 degrees to 17 degrees) and still remain in spec.

 

My buddy just installed a Unorothodox UDP in his new 350Z and is thrilled.

 

About you saying that the RVM Pully causes Oil leaks.
Its more that people dont replace the Crank seal ring.
Which can cause an oil leak. See some forget to say that thye did not replace the the seal. So thats wahy the pully has nothing to do with the seal just is behind it. Say with UR Pully you must replace the seal.

 

Belive me that area of your engine is something you don't want to go "cheap" on, buy quality and you will get what you pay for. Go ahead and buy a FSTB for $20 but don't skimp on something like this. My .02

 

Incorrect. The 3.5L can be set up to 20 deg BTDC maximum and remain in spec. You have to do some other work (Idle air volume learning) before you can go past 17 deg BTDC.

 

Sorry to continue off topic, but if the hesitation TSB is done, does that advance the timing? Thanks.

 

Negative, it does not. It is merely an ECU reflash introducing new parameters (for throttle response and other things), but does not advance timing. You can get them done at the same time, however...

 

Thanks, maybe I'll ask. It seems that if I ask them to do it, they may assume I am abusing the car.

 

Well, i've installed the RVM pulley in my car for about over 30,000 miles now. Currently at 64,000 miles. I don't have any problem with it. It's doesn't matter wether if it is RVM or anyother brands, just take your time when installing it. Power gain wise, slight notice but not a lot.

 

OHHHHHHHHHHHHHH please do not get the RVM... well some people have got lucky or they have the new UDP from the with protective ring around it





this is the original UDP that i got....

look at my RVM UDP where oil seal ate through it little...

and i changed out my oil seal and installed it correctly....

that is not the bad part..... it is the customer service that is really bad.... bad is not the word to describe it..... they just suck big time
check out the RVM review on the .org

me ---> <---- RVM

they are aware of this issue so the new model came out with protective ring around it now....... so they are aware they had a faulty set before but done nothing to fix the problem for the people who have already got the original UDP. i even offered them just give me 50% for the new UPD and i will return the bad one but they said NO..... didn't even think about it.

 

Even though I haven't owned one, I know I will NEVER BUY an RVM UDP. With everything I heard from when the RVM UDP first came out, there's a reason this problem is stickied in the General Maxima Forum. Besides that, their customer service is the worst!

 

the nissan dealership does the timing advance? You said it was free - how so? I'll do a search on this too...

 

few nissan dealership will do the timing advance... i got my Infiniti I35 timing advanced at nissan dealer b/c the Infiniti Dealer didn't want to do it....
