Light Weight Crank Pulley ?
 

Does anyone use a lightweight crank pulley? If so, does it feel any different than stock? What brand do you have? Is this a bad item to get?

Sorry for so many questions, but I might buy one tomorrow. I want to know if it's even worth it getting.

Thanx guys

Don't use them, they don't have a dampener and are harsh on the drivetrain.

The OEM one has a dampener that absorbs some of the shock and vibration. Almost all aftermarket pulleys don't have this. I had one on my Del Slo, but that was only because the asshats that I bought the car from didn't put the crank pulley bolt on tight enough when they changed the timing belt, so it came off, hit the crank pulley, busted it, and I didn't feel like paying so much to get an OEM one when I could get an aftermarket one for a fourth of the cost. I didn't notice any difference...

light pulley for a D16 = bad after 10k miles

Re: Light Weight Crank Pulley ?
 

get one only if you like fucked bearings

Re: Light Weight Crank Pulley ?
 

Thanx for all the info guys. I will really take this into consideration and say HELL no I won't get this.

Re: Light Weight Crank Pulley ?
 

THough how many people actually use the same engine for 10k or even close? You know you want it so just get it. Shiny parts are badass. I used them on a bunch of my engines but I never keep a car for over 2 years so I don't really care. lol.

I've had an Unorthodox Racing lightweight crank pulley on my b16a for oabout 5 years/60K miles with no problems. I put mine on when I did the swap so nothing to really compare it to. I've never seen such carnage blamed on a crank pulley before... where they underdrive crank pulleys or were they stock diameter?

Re: Light Weight Crank Pulley ?
 

well you got lucky!
mine ran out out after 7000 miles on one

Re: Light Weight Crank Pulley ?
 

On an UR crank pulley? Was it just a lightweight one or was in underdrived? I'm curious because I don't want to push my luck. Especially with my new motor when its done.

Re: Light Weight Crank Pulley ?
 

i had an unorthodox racing lightwieght crank pulley also ...but on my jdm D16...sohc vtec...with no problems...i had it on there for about 3yrs id say about 15k miles and then boosted afterwards with pulley and still didnt effect engine...engine is still running strong...but when i put pulley on i did notice revving was alot nicer...and quicker...so LMK on if its not good for a B series cause i was gonna get one...

Re: Light Weight Crank Pulley ?
 

Yeah, I'm not saying they *are* bad I'm just saying from what I've heard they are. I didn't really much of a difference when I had mine, but I can't say if it would do long term damage to the car cuz I only had mine on for a month or two before the car was totalled :6

If you want to be safe, there's a company that makes aftermarket pulleys WITH dampeners, but they only make them for B series. I can't remember the company's name, sorry O0

I'm going to reinforce the don't byuy them movement

Re: Light Weight Crank Pulley ?
 

I guess or actually know that the crank pulley is bad. But what kind of effect would an underdriven crank pulley have on an engine. Is it worst than the lightweight crank pulley?

Re: Light Weight Crank Pulley ?
 

People have said that non-oem pulleys cause them problem. Some said they work just fine. Doesn't matter if it's underdriven or lightweight, they don't have the dampener.

Re: Light Weight Crank Pulley ?
 

I was using a OEM pulley, think about it.

Re: Light Weight Crank Pulley ?
 

So if you were using a stock pulley that you lightened there is a chance that it wasn't evenly balanced...

Re: Light Weight Crank Pulley ?
 

What about going from stock B16a pulley to CTR crank pulley?

Re: Light Weight Crank Pulley ?
 

it was a stock pulley, never touched, as balanced from Honda.

Re: Light Weight Crank Pulley ?
 

Mista bone you confusin me... you said by the pictures "light pulley" but everywhere else you're saying oem?? eh?

Are you saying it doesn't matter which pulley you use?

Re: Light Weight Crank Pulley ?
 

He used the d15b pulley which is lighter than the d16 pullies

Re: Light Weight Crank Pulley ?
 

ah ok thanks, makes sense now lol

Re: Light Weight Crank Pulley ?
 

Well same deal it doesnt have a rubber ring in it that cancells out harmonics.It is a really debated topic.I put a CTR pulley on my LS/Vtec i just built so we will see how it looks when it is tore down this winter.A fair number of people had issues breaking oil pump gears as that is the main issue along with increased wear on the bearings.

Re: Light Weight Crank Pulley ?
 

;)

Re: Light Weight Crank Pulley ?
 

Not all OEM have it.

I used the Unorthodox Racing crank pulley on my mini/me turbo for over 1 year with no problems. Donald owns the car and the motor is still going strong.

Re: Light Weight Crank Pulley ?
 

Face it guys, the way we use our engines, none of them will last too long, so just throw on the stock CTR pulley and drive your car till it dies, then rebuild it and do it all over again.

Re: Light Weight Crank Pulley ?
 

every 10,000 miles :)

D15B7 pulley :)

BTW, you know the Y7 pulley is lighter than Y8????

Re: Light Weight Crank Pulley ?
 

Eh yeah, I hope my engine lasts at least 10,000 miles after I turbo it... At least until I have another block to swap in.

Re: Light Weight Crank Pulley ?
 

2.5 pounds for the D15B7 pulley vs. over 7 for the Z6 pulley.......

Re: Light Weight Crank Pulley ?
 

Rofl, damn didn't think it'd be that big of a difference.

Now that I think about it, when we changed my friends timing belt on his d15(b7? 95 del slo) it didn't seem to have a rubber dampener....

Re: Light Weight Crank Pulley ?
 

i've had an unorthodox racing crank pulley on my b16 for about 6 years now.. with no problems at all. i just recently boosted the car so i'll see how it works out.... ---- it.. if it blows, it blows >:D

Re: Light Weight Crank Pulley ?
 

the short stroke B16/D15 are usually OK.

But since the D16 has the longest stroke of the D/B motors :)

Re: Light Weight Crank Pulley ?
 

So what would be the lightest and I guess best pullery for the D16z6? The D15B. If not which one?

Re: Light Weight Crank Pulley ?
 

No problems here, I had mine for over a year now.The only thing about it is your ac wont blow as cold on idle.

Re: Light Weight Crank Pulley ?
 

---- it just go with the unortho...youll feel rev is a lot better....thats my opinion....just go with what you feel comfortable with ...are you a risk taker...do it ..if not dont....

Re: Light Weight Crank Pulley ?
 

keep your stock piece.

Re: Light Weight Crank Pulley ?
 

I've never changed the pulley on my engine and I never would. I've seen bad things happen, and that's enough for me to say ---- you to a lightweight pulley.

One of the problems I've heard with CTR pullies is that they aren't balanced for your specific engine. It'd probably be okay if you had it balanced with your crankshaft.

Oh and fluidamper makes the lightweight dampers.

Re: Light Weight Crank Pulley ?
 

I have ran the dhr unit and factory lightened ones and never have seen any damage on any motors except a high hp turbo b16a that killed an oil pump
