has any body have any trouble with them as far as engine.

 

They SUCK.

I dynoed my old B18C1 with the pullies and they did not help one bit. It's all bullshit and hype my friend.

The only pulley worth investing money into is the lighter crank pulley. The other crap like alternator and A/C pullies don't do a damn thing but kill your battery sooner.

 

*GASP* Not the crank pulley! What about proper crank dampening?

Seriously though, Ive always heard it is not good to replace the crank pulley, how much truth is there to it? Is it kind of like the "don't get a CAI, you'll suck up water as soon as you drive in the rain"?

 

I'm gonna disagree with the crank pulley suggestion. My friend was dumb enough to invest in the AEM alternator, power steering and crank pulleys. He did gain roughly 8hp and 6tq but knowing that the crank pulley is not harmonically balanced is not worth that minimal gain in my book. He has since removed them so is anyone interested in them... they are good really they are.

 

you can seroiusly damage your bearings of you are running a crank pulley on a daily driven vehicle
if you need weight savings take your stock pulley and have the power steering part machined off
but dont do it if you are daily driving (try an alternator pulley and power steering pulley)

 

So the harmonic balancing is pretty serious then?
Do any aftermarket pulleys come balanced properly?

 

Just dont get them. They are a waste of money. They do more bad than good in the long run.

 

does ur crank pulley cause any engine damage?

 

So far everyone says it can, and they are afraid it will, but has anyone seen it first hand? Anyone here using an aftermarket crank pulley long term, that cares to chime in?

 

its a waste of money. i bought me the AEM pullies and i had to take the **** off because it fucked up the battery twice. SO i had to put the OEM pullies back and then after while i took the power steering pully off. but i have them for sale if you want them. 75 bucks. For b16a. i had knife edge crank shaft so i guess the alternator pully wasn't keeping the charge. now everything is fine

 

wont the factory jdm civic type-r crank pully bolt up to any b-series?
i think its lighter and i know that is is balanced and dampened. $100 i believe. correct me if im wrong.

 

i have the power steering and alternator pullies on my car, and while they ahvent given me any trouble, they havent helped either

if you have a n upgraded sound system you shouldnt run the alternator pulley because there is too much strain on the alternator to supply enough current

you shouldnt run lightened power steering, alternator and crank pullies together

the reason why the CTR crank pulley is so light is because it only has a pulley for the alternator and nothing else.

i guess my point is even if they do work they aren't worth the money anyway, so you will get better bang for ur buck with something else

 

so in other words the ctr crank pully doesnt have a pully for ps?

 

Correct

 

Well **** you've now got 5 total strangers telling you that crank pullies are bad, so you should automatically assume that they are right.

SHOW ME THE DAMN PROOF!

I know some local guys running Unorthodox RACE (alt belt only) crank pullies for years with no apparent engine damage.

You guys think that they make the pully lopsided or something? Of course it will be balanced, unless your crank and rotating assembly isn't you should have no worries.

If it were me I'd love to get the CTR N1 base pully, but my funds are low right now because of my current beater-build-up so that has to wait. I like O.E over everything, but that doesn't mean that the Unorth product is shitty.

I want to see proof that a crank pully has caused engine failure - I won't sit here and read **** without proof. If you're willing to say it then be willing to prove it, okay?

Not trying to be an *******, but too many mistruths get passed around the import community and I want to see it stopped.

If it's true then it should be very easy to prove, okay?

 

Thank you. I have been trying to get to the bottom of this whole thing. Like I said earlier, I sense similarities with the whole CAI/hydrolock hysteria situation.

 

I can show you worn main bearings from my friends 00 Si B16A2. It was otherwise completely stock and never raced. He had an Unorthodox lightweight crank pulley and the AEM PS and Alternator pulley's. Other than that, he had a DC Sports 4-2-1 and an AEM CAI. The block was torn down to be built for boost and the mains showed exessive wear, due to the Unorthodox crank pulley not being balanced.
He bought an Eagle knife-edged racing crank, so while we were at the machine shop he had them to test the stock crank with the stock pulley and the Unorthodox pulley for rotation trueness. Sure enough the Unorthodox pulley was spinning the crank slightly off axis, I mean within 10 thousands of a degree, but it was noticeable.
As with most aftermarket parts, it's the luck of the draw. I could use the same crank pulley on my motor and never see an adverse effects, while my friend suffers from worn mains overtime. I think that since the risk is there and the gains are minimal, if any sometimes, why even bother?

 

Thats exactly the problem, running a UR crank pully on an other wise stock motor.

If you have the crank ballenced with the pully on there you should have no problem.

That is what I did and so far I have about 4000 miles on the motor so far (b18b) with no problems or vibrations, am i woried about it destroying the motor, not really

and yes, it is a Race pully (Alt only)

Good stuff.

https://honda-tech.com/zerothread?id=343351

 

You should remove your power steering and A/C, IMO. Then shave your OEM crank pulley and have it re-balanced.

 

That was good stuff. Thans for sharing the experience guys. Now we have more info than "crank pulley's are bad". I'm still up in the air on this one though.

 

Click that link and educate yourselves.

sgT is THE ****. If he says something is good or bad you can bet he's not talking out of his *** - he doesn't lie to look cool.

Again I've had numerous friends running the race pully for years with no problems.

 

I guess VTECVillain is smalltime compared to sgT. I've seen the imperfection of the crank balance in person using the UR crank pulley, but I guess I like to lie to look cool - j/k

 

No I didn't mean that to be a direct slap on you at all bro.

I'm just giving some background info on sgT - that's all.

 

I didn't figure you were, just had to throw the "villain" humor around that's all
