    ATI Super Damper Titanium Bolts

    Lightweight Titanium Bolt Kits for ATI Dampers are now available.

    [​IMG]



    The main advantages as I see it are, lightweight low profile 3/8-16x1 replacements for the Torx E bolt heads, and corrosion resistance for the face bolts. The original tall Torx E bolt heads can abrade brake duct tubing in some close fitting installations.

    [​IMG]

    When distancing a duct from the damper, the wheel well liner is pushed outward, which can cause contact with wide tires at full lock.

    I don't know how much shorter the Titanium bolt heads are at this time. Retail $35.95 Part# 950200T

    Just a word of encouragement for anybody considering getting the ATI over an OEM replacement...
    I just had an ATI super damper installed that I got from WMW (decent price, and fast, cheap shipping, what more can you ask for!!), and my car ACTUALLY idles smoother! The mechanic mentioned it...and when I started it for the first time, I was pretty amazed at the difference.
    The damper removed from my 2005 model year car (late 2004 production) was actually a older/Heavier design, and looks to be in good shape...turned out it did not have any cracking in the rubber, and looks to be fine. But there is still a difference BEYOND my lighter wallet. So if you are on the fence, the slight difference in $$ is well worth it to get the ATI!!

    I'd love to know what effect either of these have on that annoying gearbox rattle. I'll pay attention to any before-after comparisons.

    Any specific reason why its 1% larger in diameter and not OEM size?

    Not a question of if they fail but when.


    May need to look into these.

    My point about the rattle experienced by aftermarket clutch & lightened flywheels owners was mainly to illustrate firing/compression pulses and how much more detectible they are without a dual mass flywheel. I hope that example didn’t mislead any readers into thinking claims were being made as to a damper’s effectiveness in reducing this “noise†in an audible sense.

    Economies of scale, the majority of 4 cylinder imports have a 5.5-inch (or close) diameter crankshaft pulley; the MINI is ~ 5.452 inch.

    I was hoping it would help the gearbox noise issue, that's all. No intention to mislead people.

    As for the diameter explanation, that makes a ton of sense.

    This seems to be a nice replacement unit.
    1. Is Werkin MINI recommending the Super Damper or the Rattler, seems like two different products. Maybe the Rattler is better for a sustained high revving car?

    2. The 3lbs, 2oz lighter, I would guess that is for the early first gen cars ?? I believe the face lift first gens utilize a revised damper that is ~5.5lbs lighter than the early cars. So, that would put this at about ~2.4lbs heavier than the face lift damper. Do I understand this properly?

    3. Do we have any experience with these dampers? Has Werkin MINI put these on a few cars yet? What are the impressions? Is it nothing that can actually be felt, or does it make a difference that is noticeable? Maybe just on some cars with issues?

    The link for the Super Damper shows it is 3.60 lbs.

    Each of these options has their strong points, but since the TCI Rattler has not gone into production for the MINI, and it has no price point yet, the ATI Super Damper gets my recommendation by default. Although each product has a different approach to the same end, they both work over a wide range of rpm, at a later date it will be a matter of choice, and my goal is to allow choices.

    The late model OEM damper weighs 5lb 13oz, and as Pharaoh pointed out the ATI Super Damper weighs less.

    The Super Damper has only recently been available for the MINI; I hope to be able to provide a first hand report very soon. The Super Damper has been the overwhelming choice for many race teams, road, NASCAR, circle track, drag race, and a component of top finishers in many Engine Masters Challenges for years, plus I have endorsements from the local Hot Rod community, so it’s just a new application for the MINI.

    Thanks for the quick reply.
    So, on those choices, obviously there is only one today, but that will change.
    - What is the expected price point of the Rattler?
    - When/what application would indicate a selection of the Rattler over the Super Damper or vice versa?
    - Is it expected that the Rattler will weigh the same as the Super Damper?

    As far as the weight, I realize it is not huge deal. If you really want to save significant weight, you could find many more pounds to shave from the flywheel, than here at the damper.

    Looking forward to your report after you get a few installed. Totally understand that this is ONLY new for the MINI, not a brand new and untested design, generally speaking.

    It is a bit pricey, but seems to be a top notch product.

    When the choices are
    ATI Super Damper crank pulley @ 3.6lbs & $425
    vs
    Lightweight nonharmonic balanced crank pulley @ <1lb & $160
    I'm sure of the choice I would make & would be worth the extra money.
    I never pulled the trigger on lighter crank pulley as I really not want to "test" it myself.
    I wanted to get a newer OEM pulley for my 2002 but I like this option better. I'm just not sure I would need the Laser etched 360 timing marks.

    I don't have a price or weight guess at this time, not even a hint has been shared.

    The only objective data I have for comparison is this chart on ATI’s web site.
    [​IMG]

    From that chart it would appear the ATI Super Damper is more effective at reducing torsional vibration at higher rpm than a pendulum type absorber like the TCI Rattler, and the Rattler slightly better between 4 & 5k rpm. Looking at the positive attributes of the Rattler, the Rattler is zero balanced, this means if you balanced the crankshaft for the reciprocating mass of the rods, pistons, wrist pins, and rings, the rattler could be added later and not affect the crank's balance. The Rattler is not affected by time & temperature, no need for a rebuild later. The Rattler targets the cause of torsional vibration, the Super Damper targets the torsional vibration’s effect plus additional vibration dynamics. The Rattler is way trick from a technology standpoint.:cool: Crankshaft construction, cast or forged can help tailor the decision if we were to split hairs, but both of these products can do well with either type.

    In the end it will be a decision you as the buyer make as to which one appeals to your sensibilities; they’re both that good.:yesnod:
