    Very nice. Which brand is that and where did you get it?
  • jpciiijpciii familEE
    oh damn! I need one of those for my hatchback. The single "race" pullys are really expensive. Wanna make me one? I assume that is one of the cheap ebay pullys?
  • sic944tsic944t Wagonist
    yes sir and yea i would love to make one hmm maybe you can buy one have it shipped to me pay me a small fee say 10 bucks and pay for shipping or somethin like that
  • Are you getting it balanced ? Does it have a rubber dampner ? A little weight to the crank pulley is not always a bad thing, I just hope you know what you are getting into.

    Big end bearing woes, here we come.

    Not only does it need to be balanced well, you also need to run either A/C or PS so that there is equal pull on both sides of the pully.

    I added power steering and gained heaps of engine speed, go figure.
  • sic944tsic944t Wagonist
    well there is a debate on honda tech about this same topic
    but i dont agree with those ideas and yes its balanced
    if you put a total peice of shit on there and you adjust your belts all crazy then yea your asking for it
    ce5rtain engines need dampeners more than other like V8's they love dampeners
    honda i think are chill
    you can buy a CTR pulley ORM honda single pulley no dampener
  • HaydzHaydz Moderator
    Yes but a CTR (B16B) motor comes pretty much perfectly balanced from factory, thats why they can get away with it. Its not just about the pulley, its about the whole motor.
  • sic944tsic944t Wagonist
    ha my typing on that last post was awful my appoligies but
    ANYWAY
    i think over the duration of 200,000 or more miles which hondas happily run and then some there are issue's that do come from the pulley's
    so i feel that a single dampened pulley would be the best option but i will prolley have this motor out within 2 years for a rebuild or a replacement or god knows what so im not worried
    like i said it was only a few bucks it looks cool and was a fun project
  • HaydzHaydz Moderator
    Fair enough too, i'm not trying to knock your work, just pointing out that on that particular motor it could possibly cause some problems and/or limit engine performance. Then again, it might be absolutely fine.

    I was so so very surprised at how much quicker my ZC revvs with the power steering added.
  • sic944tsic944t Wagonist
    yes that is a strange effect

    i think these things through so no worries if it sucks im prepared ....
    i wish someone would like produce a shit load of tests on this stuff i have some many ideas and stuff with motors but noone has tried and true knowledge ....... it would be neat to see dyno pulls like on your car with and without the power steering
    and mine with and without the pulley
    you know stuff like that

    Sorry , but its not a myth. As far as the ctry pulley goes, see thats where you are really wrong. You are talking about the N1 pulley which is ment for the Type R race car series, if you look into it, it says the engines in these cars are ment to be replace every race. And infact someone pulled some more info up and they infact will ruin bearings in the long run.

    For the gain you will see, its not worth it. I just read that you are rebuilding the engine, so go crazy, just wanted to warn you.

    And as far as test go, if you look a little more someone actually did a sound wave/vibration test ( forgot the name ) but the crank pulley is ment to absorb the vibration of the engine.
  • sic944tsic944t Wagonist
    well as far as that goes you are talking about a race car .......
    it will be shifted at god knows what rpm 8,500 plus i assume
    where as mine wont see anything over stock rev limiter
    i mean i do agree that it isnt the best way to go
    but i have looked at my stock pulley and it really isn't a miracle of dampeneing im sure a little rubber goes a long way but it isnt a giant fluid filled super dampener you find on a small block chevy
    and the pulley is also under driven (the one i made) so thats a plus

    i dunno im gonna do some research on this topic cause after all this debateing i wanna learn more

    but my main rebuttle to you is simpley put it wont be driven like a race car and will hardly see the conditions that your talking about let along non stop for long periods

    the only problem i see is maybe some added harshness due to the increase in vibration but i dont think that will be directly transfered to the engines bearings

    install, and give us results!
  • sic944tsic944t Wagonist
    well i need to install the whole damn engine ! :x

    i can tell you the results.. no power gain and a blown motor do to oil pump gear braking into millons of little pices.. do what you want but i guess you dont get the point of a damper. trust me i have done this b4 :wink:
  • On a related note, customer came in this week with a blown engine, guess what kind of pulley he was running :shock: , not blaiming it all on the pulley but I'm sure it did not help at all.
