opinions on pulleys
 

i noticed ssauto crap has some aluminum pulleys and an adjustable cam gear for 180bucks!
I figure..it's just machined aluminum..so no welds to crack. Any one think this is a decent buy?

Re: opinions on pulleys
 

i wouldnt use the crank pulley

Re: opinions on pulleys
 

Look elsewhere. Those pullies are crap and use a very soft material

Re: opinions on pulleys
 

just imgain the cam gear adjustment bolt slipped :-X

Re: opinions on pulleys
 

I've used a lightened pulley but not from SSauto. Worked great and never had any problems with them. It's one of those things that people will always disagree about. Just have to try it out for yourself.

Re: opinions on pulleys
 

i had a pulley and flywheel on my old a6 motor, wasnt ss auto either but i noticed a difference.

Re: opinions on pulleys
 

I have used pullies to but after seein what happened to an accord motor with one I dont know what to say. In my honest opinion a factory one with the power units machined off and balanced is the way to go

Re: opinions on pulleys
 

this will proabably scare you away from using pullys for life

Note the date on those posts.........

A few months later I did my lightweight pulley trick, D15B7 pulley on a D16Z6.........

10k miles later........summer of 2000.........

Re: opinions on pulleys
 

Same ---- happened to me with a lightened pulley.
Chewed up all the mains and the rods were getting there.
Except mine took not even 2k miles >:(

Re: opinions on pulleys
 

While pulleys are being discussed, what do you guys think about the CTR crank pulleys on a B series?Over on Honda Tech they are the destroyers of oil pump gears etc and supposedly grenaded everybodys motor etc.I have a hard time believing this as this is a factory part for a Civic Type R that doesn;t come with pw steering or AC. This car stock turned like 8-9000 rpm so i cant see how they would be harmful?This has to be one of if not the most argued subjects in the Honda world.

Re: opinions on pulleys
 

Yes very arguable topic.
There are many brands/types of pulleys to account for.
Condition/mileage of motors.
Flywheels have to be dropped in the bag.

People generally stick with their experience and sterotype all pulleys.
I had aem underdrives on a gsr for a year and a half w/ no problems.
I have an unorthodox racing crank pulley on a mini-me for over a year w/fidanza and on a z6 before that w/stock flywheel for over a year with no problems.
(z6 replaced because stock d's don't like 20+ psi.)

So, all I can say is go with a reputable company or don't do it at all.

Re: opinions on pulleys
 

I too have had scuess with the dhr unit without problems and lightned factory pullies. I ran that unit for 60,000 miles on an old set up of mine through college no probelms. Yet I got an accord with all the bearings fucked with a no name unit but it did have 135 k on it so the verdict is kinda some people dont have problems others do.

Re: opinions on pulleys
 

+1
2 years ago same thing happened to me too.. after 2k kms ended up with lots of metal shavings in the oil pan which even could block the oil sucker thingy.. lost a cranck, a rod, and all bearings :'(

Re: opinions on pulleys
 

dont fudge with the crank pulley. go with UR pulleys or AEM tru power pulleys, but dont go for crank, the two people i've phsyically known to swap that both grenaded their engines within 6 months. hence, i have the AEM tru power pulley set for 2 years and have yet to have a problem with them

Re: opinions on pulleys
 

AEM used to sell the crank pulley as part of the set, but after seeing wear issues they pulled them off the market.

Props to AEM!

Re: opinions on pulleys
 

haha me, Josh, and Pete know a little something about that. me "dude why is my car soo ------ slow" Josh "dude your intake cam gear bolts are all loose, it's 15 degrees off" LOL


but yeah i would definetly not trust ssac for a pulley, balance is key with those. and as you know they dont tend to strive for excellence.

Re: opinions on pulleys
 

I just orederd two CTR crank pulleys.One for my B18a Im building and one for buddys LS/Vtec.I will find out the truth to the CTR pulley issue as Im currently rebuilding the motor so it will be ran from day one with a CTR pulley.

Re: opinions on pulleys
 

My friend just bought a complete UR underdrive set for his freshly rebuilt b17. I warned him not to use the crank pulley, but he didn't listen to me. I think the shiny stuff caught his eye a little more than my warnings, but hey...it's his 3 grand to rebuild it again when all his bearings go ::)

Re: opinions on pulleys
 

after reading the article on endyn's site..i'm convinced that i'm just gonna machine off the unused portion or the stock one and have it rebalanced..it all makes sense if you think about it

Re: opinions on pulleys
 

why machine it though, for looks??????

a few ounces 2.5" away from centerline does little improvement.

6-7 Pounds of the outer edge of the flywheel has a 100x or more effect at same rpm.

For example.........

4 ounce fishing sinker, with 2.5" of fishing line, twirl it as fast as you can, fairly easy.

Now take a 6 pound weight with 5" of fishing line, just TRY to twirl the damn thing. Better yet make it 10 pounds if your using a 7.5 pound flywheel. Can you get it going as fast as the 4 ounce weght? I doubt it!

ONLY reason to use a aftermarket pulley is to slow down the accessories to keep them from throwing a belt. When the belts see high rpm they stretch, allowing enough to jump off the drive pulleys.

Just like pistons have a max. safe speed, drive belts have a point when they come off.

This was one I used on my twin turbo ls/vtec...

and it destroyed my oil pump, thank god it didnt hurt any of the bearings.
