What are your opinions about the RVM UDP? Do you like it? Is it worth the money? What are the ups and downs of the UDP? Thanks for your input.

 

Anyone have a link on what the different between this and the UR one is? Or is it identical?

 

The UR is slightly lighter (I think like .2) and smaller in diameter. That's it.

 

I have my RVM sitting here next to me....I'll probably install it sometime next week...I'll let ya know.

 

I think that it is funny that it is so cheap but i guess thats just cause i support UR.

 

Ive got the RVM sitting in my garage ill be installing it this week ill let you guys know how it turns out.

Have you run the 1/4 lately bruce? I remeber the 14.0 but just wondering if you think you can get the 13s. Maybe with that nice new pulley.

 

i have a UR UDP and i was wondering if anyone noticed any good gains or any gains with it? Or did the car feel the same

 

So Bruce whatever happened to that $74 you were supposed to Paypal me a week ago? FLP Incident Part II.

 

Slight money miscalculation, but youll get it on the first when the Navy pays me, unfortunately going paycheck to pay check is kinda hard,

And Justin i havwe run my car at the track in like a year and a half so i have no idea but im adding alot of parts on my car soon so i might run it then and ill let you know what happens

...so is spending other people's money then too I guess. BTW, where did the money for this RVM UDP come from? You should really settle your debts before spending money on niceties for yourself... Seems to me you've owed Vyrus (and others perhaps)longer than the RVM UDP even has been available.

 

First off its none of your damn business about my money but a loan payment came out late and screwed my money up this month and i puchased the rvm udp about a month and a half ago and i made the deal with Vyrus.

Bruce

 

My point was that Vyrus gave you his money several months ago and you chose to buy yourself some goodies AFTER that, when you instead should have just given back his money or delivered the product he thought he was buying.

You probably are right though... it is none of my business. I just don't like it when i read that someone is getting screwed...

 

Well I was screwed no doubt... just hope Bruce actually fixes that somewhat by giving me what he owes me. And I don't see anything wrong with looking out for others - if that principle didn't exist, Roadbeast would not even be remembered.

**** man sorry that sux, i hate people who never pay up on time, or make you wait for them when you deliver...........best of luck, hope you get ur cash................so has anyone here with a udp noticed any gains from it??????

 

Has anyone who has seen the RVM and UR give there impressions on quality difference between the two pullys (if any)? If the price was close I would go with the UR just because it is an established company. But for a difference of over $100, more than double the price for the UR, I am seriously considering the RVM.

 

i have the RVM UDP installed and i didn't really noticed any HP increased but i did help with quicker response.... but then again... it could all be in my head..... i also didn't reset the ecu or anything...... or my ecu just need to learn the light UDP....

 

Did you ever end up going to the track again to test it? I remember last time you said it made your time worse. I was wondering about it. I want to buy a udp but if I can get just as good quality for a RVM for $100 less then I'll go for it.

 

If it doesn't help, and it makes you slower, why would u even get one? This thread has made me think about selling my UR UDP

 

Possibly it makes the car harder to launch since it revs quicker so it is more difficult to hold the RPMs. The theory is sound, less rotating mass = more power and reducing the power needed to turn accessories means more power to the wheels. However the difference is only ~5HP so normal variations in track times could be more than any gains from the pully.

 

so what your saying is wheel spin would increase, but from a roll it could help

 

Kinda, more like it's harder to find the perfect launch RPM in between to much wheel spin and bogging. From a roll there should be more improvement, but that's just my theory.

Edit - After some practice with the UDP you should be able to launch as well as you do without it, it probably just takes some time to get used to it.

 

Well tons of people have proven that they can launch with a UDP and even with both a UDP and a UL Flywheel, so it just takes some getting used to.

 

i havn't had time to go to track with all this holiday coming up...
i'm planning on going 2nd week of jan. or so with friends... then my ecu had time to adjust to new UDP and see how it does on 60's , ET, and trap speed.....

 

ok well i took a few shots of my pulley today....

 

and the final weigh in of the pulley....its not exactly the UPS scale, but hey, it works....if you cant read it that well, it was just slightly below 1 3/4 lbs....id say ~1.73 lbs

 

If you guys want a reliable UDP that has been tested and proven to help performance check out my group deal:

Do you sleep with those teddy bears in the background...lol jk...not a bad looking pulley at all.

 

actaully i do
