I've had a UR crank pulley on for over six months now without any problems at all. Before I got the pulley I checked into possible problems with removing the stock pulley and I know that there can be problems without having the harmonic dampner for long term use. Also, is the harmonic dampner the rubber section in the middle of the pulley for the F23's? That was the only difference I saw between the stock and UR pulley.

If anyone has experience with UR or AEM crank pulleys or knows a lot about harmonic dampners I would really like to hear.

 

AEM does not have crank pulleys.

Some people say no probs other swear it causes bearing wear.

 

ive had mine on for the better part of over 50k miles, being that ive decided to garage it because she will drink close to .5-1 quart of 10w40 every week depending on how hard i push her, when ill tear her down ill have a looksee. but thaen again i could have no uneven wear as i am only turning one 'accessory' (alternator)

oh yeah i beleive inline has ud crank pulleys with a harmonic dampener

Ditch it and get the AEM pulleys. They will give you the same power, without damaging the engine.

 

GO FI and you wont worry about the <5hp gain.

 

I been thinking about getting pulley too, but 300bucks+ for 4-5 horsepower?

 

I got one I never installed if you want it.

 

i paid 99 for mine =D

 

well not 5hp exactly, its 2-3 %... so more power, more is "saved" supposedly

 

its just freeing a pumping loss from eccess rotational inertia

 

Yeah...nothing a boost controller cant twiddle away.

 

I thought that boosted cars get the most out of lightened crank pulleys. Like atleast 2 times as much hp @ the wheels on boosted opposed to N/A for the same mod.

 

they do, the rotational physics with boosted cars is much more power happy, you will spool sooner

 

Any website or info on the inline crank pulley??

Thanks in advance.

its not on their site, call them and ask

 

Thanks..

 

just rember all h/f motors the crank pulleys are interchangeable, so they may not say for f series, just fyi

 

We should compile a list of whats interchangeable. Oil pan etc etc etc.

 

we tried this bout two weeks back. topic was something bout interchangeable parts
