Im thinking about getting a aem pulley set for my h22 i was wondering if anyone out there has any aftermarket pulleys on there car and can tell me if they are a good investment. thanks.

 

I have UR ultra-SS kit. I like it. I also have UR lightweight flywheel tho .. so both ends of the crank have been lightened. Rev / response is increased a lot.

 

I have installed Unorthodox pulley set with crank pulley on 5th gen. The car gained 5 whp and 5ft lbs of torque on the dyno all across the rpm range.

 

Hi, my name is "average h-t person" I bought lightweight pullies for my car and I have no idea if they really did anything for me, but I sure got my $200 worth

Spend your money elsewhere, unless you underdrive the accessories and use their crank pulley, which is a risk to your bearings, you won't gain anything. Get an oem euro r crank pulley and then leave the rest of that stuff alone

 

i been looking for a Euro R pulley for awhile now. Not exactly the easiest thing to find.

booooooo creepy foot doctor.

I'm a tech, have been for over 10 years and yes I very well understand the potential for bearing damage however I have yet to see any undisputed proof of damage occuring from these pullies. I dont have them and I wouldnt run them but i would like to see anyone who claims they are bad to prove it.

yaaaaaaay beer!

haha, those ads are great

 

That review has been knocking around for a loooong time. In it they state that they were only running the pulley for 25k miles. When they split the block they found deep grooves on bearing #1 and the oil pump damaged beyond re-use. I seriously doubt that all that damage was the result of the crank pulley, it sounds like they had other issues with lubrication etc to me . A number of members on here have run these pullies for quite a bit longer than that with no problems reported.

At the end of the day this pulley is bolted & keyed tight onto the end of the crankshaft, and the only real vibrations that I can see to be passed to the crank are from the accessories. These would have to be transffered through the rubber drive belts anyway, which in themselves are vibration dampeners

P.S. Am I right in saying that the Civic Type-R has a solid crank pulley from the factory?

That's also an off-brand pulley.

Firstly, DAMPERS dissipate energy through converting it into some other form of energy. ABSORBERS store and release energy in order to counteract vibration.

Yes the CTR pulley is solid from the factory. No, Honda did not invent physics and everything they do is not necessarily the ideal choice.

The crankshaft produces its own, internal, torsional vibrations, whatever damper or absorber setup is used to drive the accessories has a small effect upon them. The moment of inertia of the pulley together with the mass moment of inertia of the attached accessories are the only things that have an effect on the crankshaft's resonant frequency, the effects of these are relatively small. Cliffs: The pulley used doesn't affect the produced vibrations much, however pulleys with dampeners or absorbers aim to reduce the net vibrations.

The metal-ring on rubber-spring OEM setups aim to ABSORB the vibrations at that frequency, or at a small range around it. There is no magic absorber, the rubber in the OEM pulley is "tuned" to the frequency range of the worst torsional vibration of the crank.

The BEST aftermarket item you can bolt to your crank's snout is a real DAMPER like the ATi Fluidampr, which takes the vibrations and converts their energy to heat through the fluid inside.

Your choice in the line of crank pullies available to us in the aftermarket that come without any absorber is not going to matter a whole lot, as long as they are balanced axially, they're all accomplishing the same task. The only reason I'm not a proponent of the UR and common aftermarket crank pullies available for H series engines is that in history, they have shown to place more wear on the internals, due to the lack of an absorber.

A common misconception on this topic is that the rubber ring on the crank pulley has anything to do with the driven accessories. It does not, it is only there to ABSORB torsional vibrations in the crank.

The moral of the story: Euro R crank pulley ftw - It is lighter while at the same time it still has an absorber (unless i'm mistaken....)

 

A common misconception with these"vibrations" is that they stem from accessories or lack of internal balancing. However the most dominate force acting upon the crank is the vibration generated by the pistons and rods as they reach top and bottom dc. Anyway you look at it the crank is subject to severe stress...

exactly, like i said above

anyways....engine importers get f20b engines and need to get crank pulleys with 2 power steering section, so you can pick up a pulley from them for cheap usually...

or..in my case...FREE BITCHES..hahahaha..that snap-on pulley removal tool finally paid off

 

yea...beaty, sent him a pm already

todd told me

Is the Euro R pulley the same size as the normal h22 ones?
