are underdrive pullys worth the money

I have been pleased with the Steeda's, I got them used from a forum member that had installed a supercharger.
With a lot of highway driving I find that gas mileage jumped up about 1/2 MPG, also there is a noticeable difference under hard acceleration at higher RPMs. These are subtle changes but they are there...

For example, let's say for sake of argument that at 5000 engine rpm, there's a 10HP reduction in power needed to operate the generator and water pump. That's 5% of output for an engine putting out 200HP at 5k; but only 2.5% of the output from an an engine that can make 400HP at 5k.
The freeing up of 5% of total engine output will be more noticeable than a 2.5% change...

Hey thanks man.. I love the 410's, it really woke the car up.. I decided to buy a S/C and I recently purcharsed a Vortech V1..Being that the Vortech is a centrifigual S/C the 410's should be okay. We'll see!!

For gears you really need to have a good idea what direction you want to go with the car. If you're not going past boltons I think 4.10s are probably the best bang for the buck. For a centri supercharged car like his, 4.10s vs. 3.73s I think depends on getting traction at the track and how fast you want to go. On a turbo, I don't think I change gears at all because a turbo needs engine load to spool faster. The same goes for UDP's. If you plan on doing a blower like I do, you'll be tearing them off just like I will. Really not worth it for the small amount of output you get. If you're staying bolt on, sure, it's a few more HP to the wheels.
