I seen it but in our race motor we us civic type r N1 pulley..

 

How much do they cost?

Is this piece supposed to make power over the stock one? or just make the engine more reliable?

 

its a lightweight pully with a dampener... if they have a good price then they should be a good investment.


you guys running unorthodox crank pully's and ctr n1's (AKA a pully with a dampener)... daily driving.. your going to fry your motor.

ive heard great things about those

 

You guys ever wonder why honda just uses a solid metal pulley, no integrated dampener.

i know that b serires with the exceptionl of the n1 pulley are all dampened, they all have a band of rubber that seperates the outter ribs from the center.

even if its lighter weight?
or you just stating different diameters dont make a change in hp?

Damage maybe on the DOX but not the CTR N1

Nope... They do however in some cases release power by reducing unsprung weight... That's why you see dyno gains... Doesn't endyn make a unit like this?

 

Endyn sells the Fluidampr to help control crank harmonics.
A smaller pulley may cause less parasitic drain of hp but cannot make power.

I thought this was true as my first B16A (jdm OBD0) had the injected rubber. But my JDM B16A SiR II engine had a different stock pulley, and externally I don't see any rubber. Actually, I had a machine shop remove the power steering portion off it, and still saw no rubber.

 

(taken from http://m24x.zeroforum.com/zerothread?id=1244 )



this is a stock crank pully with AC and PS ribs removed... see the rubber?

 

Thats a stock crank pulley, but stock on what?

the 2nd gen b16 one i had definately had the rubber...a few d series dont have the rubber from what i remember.

after reading this...

http://www.fluidampr.com/torsional_vibration.htm

makes sense how the fluidampr works better than a standard rubber dampened pulley, atleast IMO.

think of a gyro

 

So back on topic. Does anyone have experience with these crank pulleys?

I have a chipped crank pulley and this seems like a good investment.

 

i am about to have a b18c1 gsr bottom end build with knife-edged crank is it worth it to get a ctr N1 pulley or should i just stick with the stock crank pulley ??

 

I talked to Professional Products today so I'll post some info soon .... I want to get tha facts straight 1st. The pieces are new, as in only been available for a few weeks, but they are avaiable for purchase now (so they said).

I think you and many others may be interested in this product.

The 90050 Powerforce+Plus Race Damper for B-16,GSR, and Type R was said to be the same diameter as the CTR N1, is dampend ( CTR is not), and is SFI certified (CTR is not).

Like I said more info soon ... I need to talk to my local Professional Products distributer before I say any more.

 

any idea of the price ??
