looking at this lightened pulley by inline four it looks nice cuz it keeps the factory rubber dampner let me know what you guys think

The price seems excessive for simply machining down a stock pulley, and they don't provide any weight comparisons. Combining this with the fact that there is no under-driving, and I think you'd find that the gains would be extremely minimal and certainly not worth the cost.

 

I had a machine shop shave off the A/c and P/s section on my pulley and haven't had any problems. It lightens the rotating assembly quite a bit and I really like the fact that there is still some rubber left in it, just like oem. It was cheap too, cost me $40 canadian. Call around to some local machine shops, its an easy mod for them.

The pulley was balanced. I took it off now because it is at the machine shop with the rest of my new ls/vtec motor and I am getting the complete rotating assembly fully balanced . Including flywheel, crank, crank sprocket, pulley, rods, and pistons. Personally I like the shaved pulley, it has never given me a problem.

 

i have one, i had it over 2 years now. No problems with it.

Thinking the same thing, plus last time I ordered from Inlinefour, all they did was lie to me... So I give it a .

Just get a type R crank pully

 

why not save $50 and get the CTR one?

The main reason that some people including myself are a bit afraid of using the CTR pulley on <U>daily driven engines</U> is because they do not have the section of impregnated rubber which makes them unable dampen crankshaft harmonics. There are several H-T threads on this topic already, do a search if you would like to learn more. A shaved stock pulley however, still has the rubber section intact, allowing it to still do its original job, only it is lighter than stock by approx 3 lbs. Any good machine shop can easily machine and balance OEM pulleys for a fair price.

Show me some of these threads. A stock ctr pulley is not gonna damage your engine, or Honda and Acura would have some major recalls on them.

There are indeed a large number of threads discussing solid crank pulleys such as the CTR N1 and Unorthodox Racing versions, though none has ever reached a definitive conclusion as to whether they cause the damage that some claim they do.

However, what most people fail to understand about the CTR N1 piece is that it is a factory racing piece (hence the "N1" designation), and not a standard factory item on all CTR's. This inevitably leads to people assuming that "it's a stock Honda part, so it can't possibly harm my daily driver". I happen to believe that solid pulleys are perfectly acceptable, but that's something that each person needs to research and form his own conclusion about. Personally, I wouldn't hesitate to run an Unorthodox pulley on my car, and did so for a number of years. I prefer it over the CTR unit because it's a bit lighter and allows the retention of A/C.

 

You've gotta love the crank pulley discussions. I've been using the SRD pulley for over a year on my daily driver and have NO problems. I drive my car hard on a regular basis. I've read a **** ton of threads about how solid crank pulleys are bad for your engine and I get tired of the "I heard" or the "so and so says this" B.S. Just research and decide for yourself.

Thats b/c the N1 pulley is not really OEM, it was made for race. And there are supported theories behind why this pulley can cause potential harm to your engine and bearings! Search and you will find.

It is balanced but not dampeened, which can cause vibrations in the motor that are a dangerous frequency that can cause premature bearing failure. For this reason I do not use this pulley. 2whp in my book is not worth it!

Ok, but who makes the N1 pulley ?

Not sure but the factory CTR pulley is different from the N1 CTR pulley

There are numerous of crank pulley threads on H-T already and they all have some really good info in them. For those of you who haven't seen them already, use the search function. I personally like true OEM pulleys and if any of you think the CTR single drive pulley is from one of hondas <U>daily driven engines</U> you are unfortunately mistaken. CTR engines come with the same pulley as ITR engines and they have rubber impregnated in them for a reason. Just my opinion guys, you can use whatever pulley you like, just trying to help.

 

owen the soy boy 'nuff said

 

like I said earlier, I wouldn't use it due to potential risks just to free up 2 hp!

But there isnt any real proof that it has caused any engine damage, but there are theories that stand behind it and suit it well. There are plenty of threads on this info, but it is ultimately up to you!

Good luck which ever way you choose.

 

get the ctr. ebay has them for around 60

 

its funny the CTR has a really nice r/s which in the end probably reduces the amount of vibration and hrmonics in the engine... i wonder why they didnt call it an ITR N1 pulley...
