I was checking out HDK the other day and notived that they ad an aluminum flywheel and I'm just wondering if anybody has tried or heard anything about this product from HDK. I've noticed that you guys didn't have many good things to say about HDK so I'm just wondering. Thanks in advance! <img src=/images/forums/snitz/thumbup.gif width=25 height=18 border=0>

Ok I have been informed that a few peeps lately have received their orders fairly quickly. I know that HDK is claiming to be turning their customer service around so maybe it is worth a shot to try to order stuff from them.

I still will not recomend them to anyone until they prove themselves a little more but I am willing to reconsider my view on them if they keep this up.<img src=/images/forums/snitz/thumbup.gif width=25 height=18 border=0> I hope they do cause it will give us another option for Hyundai aftermarket.<img src=/images/forums/snitz/cool.gif width=15 height=15 border=0>

I am currently having a custom aluminum flywheel made for July,1999-2002 Hyundai Tiburons, the crank flywheel flange pilot diameter is different than 1999 and prior. The company that I am having doing this will be selling them first of february. It will weight approx. 8lbs and should be priced about $440.00. When I get mine, I'll let you know how it looks and performs. I am also having a new damper pulley assembly made, using a friction inertia weight to dampens torsionals over broad range instead of using a stock damper which is tuned to dampen a specific freq. Anytime you install a lightened rotating component you shift the crank operating freq. either up or down, thusly making the oem elastomer damper less affective. A elastomer damper pulley assembly is suspect of having questionable dampening ability, because of the fluctuating load on the inertia ring which is the pulley, you tune an elastomer damper not by the durometer of the damping material, but by the mass of the inertia ring.

uhhhhhhhh ok. No need to elaborate I got myself a dictionary for christmas. *lol* But translation of the price might be needed for me.

Thanks, but I meant the damper pulley assembly

The new damper pully assembly will be a little less than $400.00. It has a dry friction inertia ring, which uses a friction material. The most common form of friction damper is a silicone damper. Both dampers are tuned by a coef of friction and sizing of the inertia ring. Orders are what excites operating freq. (orders are what happens every revolution, a first order is rotating assembly order and a second order on a four cylinder is a firing order). By changing the rotating mass hung off the crank, your changing the torsional stiffness of the crank. The stiffer the crank, the higher the frequency. The longer the crank like a inline 6, the freqs are lower. The reason why I am doing this damper is just for added safety margin. I am not sure if the flywheel will shift harmfull freqs into a normal operating RPM. Normally at work if we have a engine design that has a say a bad 3rd order at a operating RPM, we would either change dampers or try to stiffen or even take some rigidity out of a component to shift it out of the operating range. I hope this clears some things up. If not let me know.

Sooo...is this HDK worth buying, or should I say screw HDK and just spend my money on something else? I'm just wondering if anybody has actually bought this thing and has something good to say about it.<img src=/images/forums/snitz/oogle.gif width=15 height=15 border=0>

The HDK flywheel, doesn't have a steel wear plate on the flywheel surface. The HDK flywheel is a poor design. Anymore you don't find many aluminum flywheels built like that, meaning with out a steel wear surface. Basically it wouldn't last long without getting chewed up by the clutch disc. When shopping for an aluminum flywheel always go with a well known name. An aluminum flywheel is something not to go cheap on.

Thanks, that just what I needed to know! Any reommendations on a set of cams, anybody?

CAT makes a nice set, they are suppose to deliver about 15hp to the wheels

HRD- Who is making the flywheel for you?

Fidanza will make a 9lb unit as long as we can get 10 orders together.

<img src=/images/forums/snitz/approve.gif width=15 height=15 border=0>

Tried before, but got only 2 responses...random and....I forget the other.

Anywho, let me know.
