I see alot of people on here that have them, and get pretty good gains from them. I was talking about them with a shop about getting some installed, and they warned me to stay away from them because they can cause terrible damage to a engine.

What are the chances of this? Still worth getting?

 

search is your friend, this has been discussed 3000 times.

 

if you buy cheap knock-off brands, there is a possibility they are not perfectly ballanced, and they could, in time, cause detrimantal damage to your engine..

If you get UR Pulleys, you should be fine... many many members have got them and none have yet to announce any problems. Mind you I've yet to hear any problems caused with other pulleys, but it would be safe to spend the extra money and get the more expensive pulleys, the UnorthadoxRacing Pulleys.

 

the worry about them causing damage comes from people who have replaced them on cars that had harmonic dampers on the crank. Honda doesnt use them. if its a food brand like UR there isnt any thing to worry about as far as them causing damage on a honda engine

 

ive had my 50 dollar megan crank pulley on for over a year and its been working damn good.

 

It's not like a low quality pulley is going to make your car explode. A poorly balanced pulley can damage crankshaft bearings over time. But, given how well Megan makes headers, I am sure their pulleys are just fine.

 

well said.

but like fstty said, some engines have harmonic balancers. Looking at my stock pulley which got replaced by a UR_c.p, you can tell there's nothing to it, no springs or anything...+ there's a huge difference in the weight AND diameter = here's where the gains come from.

 

UR Crank pulley Check www.unorthodoxracing.com for the dyno sheet.

 

since when did UR get into the food industry? maybe i should pick up one of their UR power bars or something, might give me an extra 5WHP running around the office today! LOL!

 

fsttyms1 is correct.

 

how much do used UR crank pulleys go for, and has anyone had their engine fuck up due too a low quality pulley?

 

you must be spanish-cheap my friend.
