I got the new Modified Mag magazine and it had the new Unorthodox Racing UDP for Acura CL/TL and Honda Accords. It says it shows gains of 20HP and 20lb/ft to the wheels! How much are they smoking there?

Well, if you think about it. If you did the first dyno with the A/C blasting, the radio on and and flipping the lights on and off, the dyno after the pulley swap could show significant gains.

I think, in response to your other question, that the UDP is going to be more valuable when your accessories are all for sure. You're underdriving the belts to divert less power to accessories thereby reserving it for the wheels. Well, if the accessories are not running, then that power isn't lost driving them. So, am I crazy? I don't claim to be an expert, I'm just making logical assumptions which could very well be wrong.

In the situation which most people drag race, the benefits of the underdrive pulley won't be realized if all the accessories are turned off and you're driving in a straight line. Right, am I crazy here? This is likely why we don't see the big-time results which companies like Unorthodox Racing claim on their web site. They claim something like 10-15hp for the UDP on the Max, don't they? Maybe they do their baseline with everything cranked up and then install the UDP for comparison.

Lets put all butt meters away and look at an actual dyno sheet of what an underdrive pulley did for my 2001 Dodge truck. I know this is not a Maxima but certainly a good test of what a pulley is capable of doing. Look at the curve and how it shows gains throughout the curve. That is some pretty good torque gains.

This was done on the same day. Dyno was ran, pulley installed and dynoed again. No ac or anything else on.

Tony,
Yep, worked for me too doing that. I wonder what is going on with that site?
In any case I got 6.6hp and 17.3 pounds of torque from the pulley on my Dodge truck. Pretty good gains throughout the rpm range too.

I installed my UDP today. All I have to say about the install is to use the starter technique to remove the bolt! My oem UDP came off incredibly easy doing this. I blurped the starter and then looked at my crank pulley, the pulley completly unscrewed it's self! I managed to strip the 12mm bolt on the top of my AC pulley belt tensioner piece. I some how mangaged to fanaglre the belt off adn then back. Total install time was about 1 hour and 30 minutes(I installed one before on my 95 too)
As for my butt dyno. I emmediatly noticed a nice gain in low end and mid range TQ. Comming off the line it is a bit easier now and it moves to redline a hair quicker.
