CTR Crank Pulley on B18b?
This post is for those with LS's and B20's!
I have done some searches on the CTR pulley and have found some good info but not exactly what I am looking for; so I have a few Questions:
1.Will the CTR Crank pulley throw my bottom end off balance?
2.Is the Pulley balanced from the factory?(Seen this asked a billion times but never answered)
3.How much lighter is this pulley than stock?
4.Are the timing marks misaligned?
5.What all problems have any of had with this pulley? Is it worth it or not?
Here is my setup:
B18A Block/B18B head
-Mild PnP
-Crower 404 w/ JG Cam Gears
-Crower Valvesprings
-Ferrea SS Valves
-Cometic Head Gasket
-Skunk2 Mani
-64mm TB
-Modified Iceman intake
-JDM ITR 4-1 header w/ 2.5" collector
-No Cat
-2.5" custom piping and exhaust
-P30 B16 Pistons
-Stock Rods
-GSR Tranny w/ LSD
-Exedy Flywheel
-Clutch Specialties 6-puck clutch
-H22 injectors
-Walboro 255lph fuel pump
-SAFC2
-Chipped P75

1. The N1 pulley will not throw it off balance, assuming you have both the bottom end and the pulley balanced.
2. It's not perfectly balanced from the factory, but is "close enough" for most people not to worry.
3. It's a couple of pounds lighter than stock. I don't have an exact number.
4. The timing mark for TDC isn't misaligned, I'm not sure about the others, however you'll probably want to tune in the ignition timing anyway so it really shouldn't matter.
5. I've never had a problem with it and recommend it highly.

1.Will the CTR Crank pulley throw my bottom end off balance?
- The CTR crank pulley is neither rotationally balanced or harmonically balanced from the factory. I wouldn't worry about the rotational balance, but I would worry about the harmonic balance.
3.How much lighter is this pulley than stock?
- The CTR pulley weighs about 2lbs
4.Are the timing marks misaligned?
- No
5.What all problems have any of had with this pulley? Is it worth it or not?
- You need to use a different alternator belt due to the size different. It is not worth it.

I see people talking about the harmonically balance of crank pulleys. I don’t understand how an oem part that is on the ctr would be dangerous to run on a b18b or any B motor? Can someone please explain this to me.
Thanks

Re: (B18OnTop)
Its not an stock part.
Its an aftermarket RACE part used on the CTR endurance cars, that get rebuilt after every race. Hence "CTR N1" pulley.

So with all this, not a good mod? I heard if I want to install this I will have to lose my power steering, is it ture (I drive a 99-00 SiR B16A)?

Yes the purpose of the N1 pulley is to reduce drag on the engine by reducing all belt driven accessories. Power steering is an accessory, consider it gone.
It takes your three belt pulley out, and replaces it with a 1 belt pulley for alternator only.
I have had mine on my B16 for 80k miles with no problems what-so-ever.

Re: (Hater)
i hear a lot of bad things about this pulley.
it could be just things past along and people repeat the sayings, but have never tried the pulley themselves.
because it doesn't have a harmonic balancer is what i hear is the bad thing and will mess your motor up. this is probably what keeps me from getting one.
isn't the type r crank pulley smaller than the other b series crank pulley?

Re: (Waachback)
There are two schools of thought on this.
One, that dampening harmonic frequencies in the crank IS important, and it must be done to prevent premature bearing wear.
Or, that it really doesn't make a difference in the life of your motor.
There are most definitely harmonic frequencies in your crank, it has been tested. You have to decide if you want to risk it or not.
If you don't think its going to effect the life of your engine, you might as well get the lightest pulley available (which are often less than 1lb), not the 2lb honda one. Its not like its safer because its honda.
If you do think its going to effect your engine, fluidampner makes a single pulley with a better dampener than stock. So you can remove your PS/AC sections and dampen the frequencies better.

So are you saying to try the Fluidamper over the CTR N1?
What about a stock CTR pulley is it different than the N1, or are they the same?

one of your posts in my search said that your timing marks werent lined up right with this pulley!

Its up to you. THe fluidampener is not lighter than stock, but it does have a better dampening ability.
The stock CTR pulley is the same as the stock B16 pulley.

Thanx for the info! I think I might just stay away from this pulley! Its not worth the risks for only 2-3 HP gains!

Re: (hybrid_vtec)
I think stock is 10lbs and N1 CTR is 1.8lbs or something.
Talk to CHAD on the board, he has used it for a LONG time on many motors
Who races and mods engines that plan on keepin them in over 100k miles anyways? j/w
Goign with anything taht isnt stock will also have an adverse effects, How extreme you wanna take it is up to you

Chad has also been through a lot of motors, and does HC no?
This sounds like a street motor.
It has been documented, the stock pulley does remove harmonic vibrations, and running a solid pulley results in harmonic vibrations.
A fluidampner is not stock, and it dampens better than stock.

Re: (hybrid_vtec)
the CTR N1 crank pulley is about 2.5 pounds and its balanced from the factory cause whether its a stock part or not its still a Genuine Honda part and they wouldnt put it on their cars if it wasnt balanced. its worth installing because it frees up horsepower and every little bit of power helps, also you'll get better throttle response. those are FACTS ladies and gent's not thoughts
go to a local car shop and get a alternator belt cause the CTR N1 crank pulley has a smaller diameter and your battery light may go on but its nothing to worry about.

No and No.
Its neither rotationally nor harmonically balanced from the factory. That is a fact.
There is NO highly compressed rubber to act as a pulse dampener, it is a solid peice.
I picked one up a while back, and sent it to a machine shop to get it balanced by itself and they did have to remove material to do so. Further, it is not perfectly balanced untill you balance it WITH the crank and flywheel as well.
