I'm relatively new to the Board and don't know anything about aftermarket underdrive pulleys. I got on the Southwest website and they have none in stock. Has anyone installed one on a 4th Gen Maxima? If so, what benefits have they seen and where did they buy it?

 

If its your 1st mod dont bother. Some members that drag race found little to no addition in power, meaning their 1/4 mile times didnt change. Dont get me wrong, they do free up a few ponys. Its better if you have a bunch of mods already, like a last step in all motor. If you dont have any mods yet get a Y pipe. Its about the same money but you get up to 30 hp. If you still want a UDP get the Unorthodox Racing pulley, its the best on the market. This site tells all http://maxmods.dyndns.org/

 

Thanks. I just got on that website before seeing your response. My car is stock. I have recently bought a K&N panel filter as I don't want to go the CAI route at this time. I have also recently installed a Vibrant FSTB. I have a Budget Y-pipe on order and should see a difference in that, hopefully with slightly improved fuel economy. I was just wondering what the best bang for the buck is after the Y-pipe. Is an upgraded ECU worth considering? What is #2 following Y-pipe?
