Pulley Question

[k2c69n]

Has anyone put new aftermarket pulleys on their car and if so, how well do they work?

[Furious]

from what ive heard, they arent hte best bang for your buck, but they do work. not much more i can say only because i have yet to try a set

Hmmmmmmmmm.... seems like a great value add for me.

I just purchased the Turner Pulley kit....... should be here by the end of week. Claimed 10rwhp on a 95M3 for under $200..... (you get a $64 back when you return one of the 2 alternator pulleys they send you)

You are definately going to have to let me know asap when you get those in.

Im not gonna have a chance to put it in for a week or two, but I will post back.

In all my research on these cars, it seems like this is the last of the 'cheap' upgrades you can do. After the, CAI, Exhaust, chip/shark pulley kit, you'll find yourself spending $1000+ for the same about the same boost in power.

Pulleys are a great upgrade to do.. It all depends if you have aftermarket amps or sound systems too... due to under driving the alternator... or no underdriving it... some say its risky to spin that pulley a little less than normal..and some say it isnt all that risky... I have the Rouge Eng. Pulleys.. which are rather nice... To answer your question.. I think they work rather nicely... it was worth the money..

Good Luck

Excuse me for being so uneducated, but I need to ask otherwise I'll never know.
When you are 'installing pullys', are you just replacing the round pulley with another lighter one with a different or same diamater for each engine component? or should the diamater stay the same for each item?

Alternator's don't produce their full rated output until a specific RPM, aftermarket amps may benifit from a smaller pulley to spin the alternator a bit faster, good or bad idea?

I would say it is a good idea to downsize the pulley on the alternator if you run big time amps.... but I have no idea what will happen when you redline your car, your alt. will be moving much faster........

[bitcore]

Not too much faster, just more amperage. Your voltage regulator may get ticked off after a year or two

hey guys. i havent been on the forum in a while. i never really got the point of pulleys unless, like said earlier, it is your last basic mod before droppin big buck. to anyone who has them, how much of a hp and torque increase is there? cya guys

Well there was a issue a while back about a blancing Problem but Here's a quote from the URI site:

"People are getting their crank pulleys confused with the harmonic dampers found on some V6 / V8 engines. "Harmonic Balancer" is a term that is used loosely in the automotive industry. Technically, this type of device does not exist. The "balancer" part comes from engines that are externally balanced and have a counterweight cast into the damper, hence the merging of the two terms. None of the applications that we offer utilize a counterweight as part of the pulley as these engines are internally balanced."

IMHO this mod best bang for the buck mod. Remember 3.2 have a forged crank, its not going to break. The only damage could be done is to the bearings.

you got to think this way little things like pulleys and cold air intake ships and ligther parts will latter add up tp a some how big HP gain but if you wanna get the best of the pulley here whats you got to do:

firts removed your A/C compresor the get rip of the condensor infront of you'r radiator and the removed the fan blade w/clutch and then drop the pulley by you removing all this you'll be getting out most of the real power of the I6.

but you'll have to forget about a hot date with no A/C

if you all this the you'll really feel the dferance.

ive seen them put on other cars and the power is there not HUGE but its there for sure!
