LS Tech: How to Assemble an ATI Super Damper

[@hokie240]

Just wanted to say I have been watching a lot of your videos recently, and these videos are awesome and very informative. I am currently going through an LS and your videos have provided a lot of info for me.

[@ScrufsGarage]

Sorry, late on the reply... but thanks for watching. Very happy to hear the videos are helpful!

[@Tony240zt]

Came for the torx tip was not disappointed, thank you

[@ScrufsGarage]

Awesome, glad to hear the video was helpful!

[@Andrew-jh5uv]

Legend mate putting one on my Cressida didnt even know about torx plus 👍

[@Z06GT1]

Thank you Scruf. I really appreciate your videos.

[@ScrufsGarage]

Happy to help!

Can you delete the ac pulley, or does it need to be installed with that set up?

[@ChevyS10LSUK]

I had the same question. As I don't run ac

[@chuckwolfe]

Yeah, you don’t need to use the ac pulley if you’re not going to run AC

[@zachstumpf1962]

According to Ati you should use all 9 bolts. meaning yes you should run the pulley

[@RaGey]

Thanks man that was just what I was looking for!

[@ScrufsGarage]

Awesome! Glad this was helpful. It's not "complicated" but seeing it really helps.

[@blakeminson6518]

Do you know how often the o rings need to be replaced/damper rebuilt?

[@zachstumpf1962]

Was the torque specs for the long bolts the same? i thought i read 27 or something

[@onewheelup]

that is so stupid damn so now i have to buy tools too,why couldnt they just use regular torx i swear and i am having hell getting the hub to seat all the way down on thew crank ive got about a 1/4 inch to go but i cant keep it from turning so im trying to make something to keep it from turning,my rachet straps are stretching,i usually use just one to remove the oem balancer on my 6.0 LS and reinstall but not with this hub,any ideas please someone

[@jessebunker6062]

Remove all of the bolts that you have installed. Then use the three threaded holes to jack screw the hub fron the pulley. Then clean the inside of the hub, make sure the dot is in the correct position, and try assembly again. Go slow, then remove bolts one at a time ,apply loctite, and torque. Your home.

[@onewheelup]

@@jessebunker6062 oh i got it,but it was hard as hell to get it to go on,the oem balancer i can do that in like 10 minutes,anyways the other part that sucked for me was routing the piping and the rubber sleeves,but its running,i made like 550 fpt to the tires with me shifting to soon at 5200 rpms haha then i ran out of injectors which i knew i was going to do,ive got some bigger ones but my tuner wants to try something else first,some operating system pulsating the injectors,i have no idea what that means lol,thanks

[@zunySSBM]

I have a 2000 c5 vette that needs a damper pretty soon can anyone send me the exact ati super damper I need please? Also what’s the benefit of the 10 percent underdrive

[@deeznutzz101]

Go to summit, get the 10%

[@ablaylock4273]

ever try the tci rattler?

[@ScrufsGarage]

No. I had an Innovators West balancer on my supercharged Mustang a few years ago and was satisfied with it. But I haven't run a TCI yet.

[@Boosted370]

How do remove the damper from the hub?? What are those 3 really small holes all about?? Thanks

[@nzigg8161]

I have heard to maybe heat the hub up with a cool engine to help press the hub in? It that correct or internet jumbled

[@ScrufsGarage]

Yes you can, but be careful not to damage the rubber portion of the damper. The top of page 4 in the instructions discusses heating aluminum hubs by placing them in a pot of boiling water for 5 mins. www.atiracing.com/instructions/Super-Damper.pdf

[@WATCHMEWRENCH]

Nice balancer choice

[@ScrufsGarage]

Thanks. The ATI balancers are a bit pricey but they are a really nice piece.

[@deansperformanceracing5730]

Well Done

[@Debkghtulvkfjkjfxjjcj]

What’s the benefit of the 10% underdrive?

[@lsedanolg]

More horsepower

[@Boosted370]

Can they only be assembled the one way? I don't think I lined up the offset hole on the damper with the indexed mark on the crank hub. Everything bolted together perfect but...

[@ScrufsGarage]

Honestly I don't recall if there was a way to assembly it w/o lining up the index mark. I'm guessing you already have it installed on the car? If you're nervous about it, you could call the ATI tech line and ask them. I would do that before I went through the hassle of removing it from the engine. I think you're gonna be fine though. Let me know how it goes.

[@allmighty1017]

What size bits are TP40

[@ScrufsGarage]

TP40 is a Torx Plus 40. So TP40 is the size. But note that Torx Plus bits are slightly different than regular Torx bits.

[@LineMUp321]

Now... why couldn't they have just said exactly what you said in the video in the supplied instructions?

[@ScrufsGarage]

I agree. For me, seeing it makes a lot more sense vs trying to read it. Thanks for watching!

[@EdgarRenteria_]

If i delete the ac do I still need to add a ac pulley?

[@ScrufsGarage]

Good question. My default answer is going to be check with ATI; I don't want to steer you wrong. I thought there was a separate part # for w/o ac, but I can't find it now. The rear ac pulley doesn't impact how far the hub would seat on the crank, so that shouldn't be a problem. You have 6 bolts that bolt the main pulley to the hub... but you would lose the 3 bolts that pass through the main pulley and hub and thread into the ac pulley. Only ATI could tell you if the 6 bolts are sufficient, or if all 9 are required. Also, removing the ac pulley would change the total weight of the balancer, so I'm not sure what effect that would have on the dampening... probably minimal. But again, a quick call to ATI would be best. Let us know what you determine.

[@KeepinItReal890]

no buy a race one. duh

[@chuckwolfe]

No, you need to use 9 bolts, so where the shorter 12 pt bolts are is what you’ll use to mount your sc pulley with their hardware, and the notaped holes that the ac pulley go would be open/empty

[@Mr.Beastforpresident]

Why not the Fluidamper brand? Many have said its much better and lasts longer

[@ScrufsGarage]

Honestly I think both products are probably very good. In all of my research I never read anything bad about ATI, and they are used in some very serious race engines. But that's not to say Fluidamper isn't also very good. I ran an Innovators West unit on my supercharger 4.6 Mustang in the past and had good results with that as well. So there are several good options available.

[@Mr.Beastforpresident]

Scruf's Garage Makes me wonder what harmonic balancer high RPM NASCAR Engines use and Formula 1 Cars and Koenigsegg. What I don’t like about the Fluidamper is the rotating weight, seems it would put twisting stress on the end of the crank where it bolts up when fast revving and braking/slowing down the engine. What I don’t like about and have seen with the ATI damper is the rubber cracking and separating. To me the solution would be using high quality/high temp/oven type silicone in place of rubber.
