Anyone have Troyer's underdrive pulley set? Or, which pullies do you have?

 

I've had my Troyer pullies for a while now and zero problems. Install is easy and be sure to get the shorter belt before you start. The new setup uses a belt that is about an inch shorter than stock. I can't say about any other brands but I have read about guys running ASP or APS, it's one of those two names. I think Jeg's carries that brand.

 

do you like them? do they provide any noticeable increase in HP/MPG?

 

I had them they did help off the line with the E-fans I got a few more MPG's

 

Troyers are ASP.

 

Troyer says 12-15 rwhp with pullies? I find that hard to believe can anyone prove this?

 

How hard are they to install? Any truth to the rwhp claims?

 

I always said that underdrive pullies dont belong on trucks. They cause issues with the earlier model trucks that's for sure. Maybe the newer trucks are different.

 

This is the one mod I didnt go to the dyno after I put them on, but I did go to the track an it ran .3 faster with them so they do help out and they are not hard to install you just need a 3 jaw pulley puller that you can rent from any parts place and some basic hand tools.

 

Sweet i might have to order me a set

 

I think they are way over priced

 

Where do you order a set from?

 

I had them, easy to install if you're familiar with removing pullies. Even if not the instructions are sufficient. I had Troyer pullies, they helped me a tad off the line but it was HARDLY noticeable. I took them off, I left on my e-fans, intake, exhaust, removed cats and every other engine mod. Those were the only mod I removed from disappointment. But to each his own, sounds like some felt more...

 

I am very happy with them. The biggest thing I noticed was better acceleration. I can't say my mileage changed a lot but I can tell you it didn't drop even after the bigger tires were installed.
