i would possibly be interested on an ati pulley. its not on the top of my list but i may be in too. i would want to keep my A/C though.

I might be interested in sponsoring the GP if you can get 7-10 together I will do it for a smoking unheard of deal!

oh snap...it's on

Edit: list moved to first post

FILL THE LIST UP FELLAS !

add me to the list

cals400ex, you in?

Smoking, unheard of deal?...? I'm down!

you're on the list now :thumb:


no turning back :lol:

As long as the "deal" is worth it...Im in.

3 or 4 more and we can get this goin'...i know there's more people out there needing a great damper!

Start advertising I guess ;)

i put a thread up in the FS section on a local forum, that's how a98ws6 found it :D

feel free to tell your friends :nod:

I'll pull the trigger and get one depending on how good the deal is. I usually see #917264 for about $450-460, so I have held off.

Put me down as definitely interested.

i'll put you down then!

CHRIS! It's looking like there's lots of interest here, how good of a deal are we talking here? I'd say $5 off and free shipping won't cut it with most of these guys if that's what you were thinking :jest:

Godfather deal :)

:lol: gotcha

yeah, i might as well join the fun.... i assume this is for any ATI balancer? i know there are different models out there...

917271 is the ATI unit Id need. Was quoted $359 from one of our sponsors. >>>> Beat that price with your "godfather deal" and its on. :)

:) Thats normally only $379.95, $359 is an OK deal but not what I would consider something you can't refuse. We need two more to hit 7 and I'll pm people with prices.

part number 917246 and delete the a/c pulley....



:confused: Not entirely sure what you meant. #917264 is set up for cars with A/C. If I recall, there is a different model # for cars without A/C. There is also one that is 10% underdriven for LSX cars.

I need #917264 because I am definitely keeping A/C on that particular car. :lol:

cals400ex, you're on the list...no looking back now.

Chris/guys, "part number 917246 and delete the a/c pulley" is verbatim what John at ATI told me i needed. in fact here's what he put exactly, copied from the email:

Ok the damper for you is our 7.5" aluminum shell assy with steel hub partnumber 917246 and delete the a/c pulley

I would be interested if the realistic price was somewhere are around 300...

I kinda seriously doubt Chris can get a $470 pulley for $300ish...BUT i could be wrong, he hasn't given out figures yet...i'll keep your name off the list (UNLESS CHRIS CAN GO THAT CHEAP) for now, but keep an eye on this thread, you never know ;)....what part number are you wanting?

I plan on running my EWP and only the alternator off the crank so i need whatever pulley that is? Whatever underdrive will benefit me the most?

That's what i'm doing too...i forgot to ask John at ATI if it made any difference if i ran a manual rack instead of power steering, but i don't THINK it should make any difference...therefore you'd want the same damper i'm getting :nod:...but you might double check...

2000_SS, ignore my :confused:. I transposed the digits in your part number. I'm talking about 917264 and you are talking about 917246

Looking forward to hitting enough buyers and getting a price. :D

take my name off the list...didn't realize they were that much money.

Thank you Ben, lets be realistic people. ATI is the top of the line damper. Typicaly the 10% fbody with a/c sells for $444, its the same model number for the GTO as well :)

Going to run my stock rack, looped.

Memorial Day BUMP!

John at ATI responded to my email:

Yes I switched the numbers 917264 is the f body and remember to delete the a/c pulley when ordering.

I'm in if the deal is good. I need a dampner with a/c and the more durable (higher durometer rubber for street/strip use) Shoot me a pm so we can talk about what I need for my application. Or if anyone has an idea let me know. Build is a 408 lsx block build w/ tfs 6 bolts with a custom twin 72 kit. Keeping the a/c and either a 10% underdrive or stock diameter ati dampner. Either way I'm in. Thanks Chris

scroll down to the LS1 chart...you SHOULD be able to get your part number off of there. if not, ATI can help get you lined out or i'm sure several vendors on here could too ;)

you're on the list!

I'll look at the site but I'm going to talk with ole blancoss as well. Hey what's the advantage of going with a aluminum shell , steel shell ect. or disadvantages?

How much for a 917276

How much for a 917276

won't know until the GP is a go...i can guarantee it'll be cheaper than you can find anywhere else...if you're for sure wanting one, just looking for the best price, let me know...i'll count you in and Chris can start PM'ing prices.

i don't want anyone on the list that isn't 100% committed to buying :chug:

One more and the GP is a go!! Lets get it done!

RUNIN11Z added :)

Tnx Ben, GP on!
PM me with your part numbers and I'll give you the price.
We only needed 7 :)

Just give us a call and leave a VM with your number if we are not available. NO GP needed, no "10 people needed", we'll just get the price for you. Some people are on a time constraint and need their pulley. Thanks.

Thanks, but Chris has it covered on this one :thumb: I can't do ALL my business with you guys :lol:


GP is on fellas, let Chris (99blancoSS) know what you need and he'll get you set up :chug:

Tnx Ben, GP on!
PM me with your part numbers and I'll give you the price.

Sent you a PM earlier!

Sent you a PM earlier!

Got it. 25% no a/c?

I sent you a PM yesterday...

Ok, Ben is getting the OEM size minus a/c for those who were wondering.

25% with no a/c is 918844 with ac/ 918845

10% with a/c is 917576 and the Fbody and GTO are the same model number

pm's sent with pricing, anyone else interested pm me for GP pricing.

Chris's prices on these pullies are STUPID, anyone thinking about buying one now or in the future would greatly benefit from ordering one from him NOW ;)

ati told me the part number for the ls1 f-body 10% underdriven with the A/C is 917276 and you listed it as 917576. i just want to make sure i have the right part number before i send the money.

i am leaving town right now until monday so i will have to wait until then to order it to ensure that i have the right part coming.

check ATI's chart on their site (i posted a link on the previous page) and you should be able to determine the part number. i was told the wrong one at first by ATI too, but the corrected it.

heres the link

There is two part numbers for 10% with no A/C??? Whats the difference? Also, is it best to go without a underdrive and just do the stock size without A/C since I am only driving the alternator off the crank?

This is what I was told by john a ati:

The easiest way I can answer that is as HP and RPM and weight of the crank increases the damper inertia weight needs to increase, so on a stock stroke motor of 3.48” and stock HP of , lets say 400HP I would run a 25% UD and take advantage of the weight savings and the drop in acc speeds. Now with a 4.25 stroke crank and 700HP the 25% UD damper is overworked and not the best choice for your engine now and the 10% UD can be used as the smallest damper I would put on the engine and you still can have the drop in weight and the slower acc drive but on high HP cars or any street driven car or road racer I always like to put the oem size 7.5” damper because you can never over dampen an engine but you can under dampen it.

part# 917243 has an aluminum hub. I would call ati, their tech guys are great.

They told me to go with the steel hub for all around street, roadcourse and occasional drag use.

Good advice on both points. I told a customer the exact same thing about the aluminum hub vs steel. ATI will also tell you for street use to go with the 10% and not the 25%

When you can beat Jegs or Summit by a decent amount with the shipping included then its a steal! If you haven't ordered your pulley yet then do so. I know not everyone who said they would buy has so go for it! Thanks for the help Chris.

i don't even see 917576 on the chart, so i am going to go with a 917276

that's PROBABLY the right part number, but i would verify it first. several other people, including myself, were given part numbers by ATI reps that were 1 digit off, or had two digits reversed.

Ben, I'm back from the LTX Shootout and just PM'd Chris.

Thanks for putting this together.

I'm kinda new to the group purchase deal here...but is this limited to just the ATI dampner listed in the first post, or is it open to any ATI dampner? I'd be intrested in a 917268.

any ATI :) pm you in a couple with pricing

Crazy prices, wont be beat anywhere. We have 3 paid for so far..??? Best damper on the market at the lowest price you will ever see it.

i sent my money via paypal yesterday. good deal on these pulleys.

Do you have # 918853?

I'm trying to find a replacement for an 05 GTO procharger installation.

pm'ed with price :)

917271 is the ATI unit Id need. Was quoted $359 from one of our sponsors. >>>> Beat that price with your "godfather deal" and its on. :)
I smashed your previous quote, is it on or what, I would like to get these ordered today

Hope this isnt a stupid question but I just bought a procharger kit and its got the upgrade sdce 8 rib setup. Do I need this dampner to mount my other pulley? If so id like to keep the ac. not sure on what underdrive if any to get. Thanks

I'm just curious what the ETA is on receiving our orders?

I hope to have them today. They were shipped over a week ago now. I always ship 2nd day so you'll get them before the weekend hopefully. I've got 7 boxes ready to pack them in and post :)

I'm interested! Please PM the price for a 10% underdrive with A/C which I believe is 917276. Also, what belt is recommended to run with the 10%? I'm currently running a stock pulley setup with a Katech tensioner. Thanks!

Awesome.

For anyone that's on the fence about this, don't hesitate to go ahead and buy. I'm sure for business purposes I can't post the prices I was quoted, but I will say it was a great deal cheaper than I could find ANYWHERE else and even cheaper than what some people try to sell used ones for.

I have called many times trying to get ahold of chris at cc performance and can't get an answer

Is this still going on?

Sorry was busy in the shop but we got it taken care of today :)

The dampers have finally arrived (literally 10 minutes ago). I had a few extra but am not sure what is left at this point. I can do another GP is there is sufficient interest if I don't have what you need.

Sorry was busy in the shop but we got it taken care of today

Sure did. Thanks again for the killer price :rock:

OK we are going to do another GP, pm me with your needs. This includes all of ATI's dampers not just GM models

i was curious when the original pulleys were going to be shipped out? i am in no hurry but i would like to know when they are coming. sometimes they leave this stuff by my front door and my neighborhood isn't the best by anymeans. thanks

They are on the way!!. I got trapped on the phone Thursday during shipping pickup/drop off and so they went Friday instead. They will be there on Monday. USPS, white box with red stripe on it.

I do have LS1 timing cover seals as well if anyone wants one. Just pm me and I can send them out ASAP. 2nd day delivery is only $5 for them :)

thanks a lot! like i said, i won't be putting it on for a while but i just want to make sure i know when it is coming. good deal on these pulleys

Please see my signature, how low can I go with underdrive? I would still like a/c. Please pm with prices of options, thanks!

Awesome deal here everyone! Glad to see someone help us out when times are harder for a lot of us! Hope to do more business with Blanco!

Anybody know what the difference is in the 918853 and 917242?

Anybody know what the difference is in the 918853 and 917242?

918853 is for blower setups, 917242 is the OEM diameter pulley with an A/C pulley, which is what i have minus the A/C pulley. the 918853 pulley would be, I THINK, for a cog drive procharger setup or something similar. email ATI with any questions you have for definitive answers, they're VERY thorough and informative :nod:

I have 1 .... 917276 left... 10% UD w/ac

and 1... 917271 LT1 10%'ish

anybody here have any pictures of the hub installed on their crank? mine isn't going on the way i imagined it would and i'd like to see exactly what it's supposed to look like.

can you pm me the price of the gp deal. 10% w/ AC. whats the difference with these dampner with AC and no AC? mine is a true street car but it will see a decent amount of track time for fun so should i stay with a 10%? its not a dd if that matters

with new front seal $430 to your door 10% with a/c

The ATI Serpentine Super Damper contains grooves for serpentine belts machined into the outer damper shell. The dampers come standard with 6 outer grooves for standard OEM drive systems. 8 & 10 grooves are availabe for supercharger or turbo applications.

this is messing with me. i thought the super damper would be fine the way it is? do i need more grooves with my 8 rib setup for my d1sc or will it be fine because it seems that i need more grooves for my supercharger setup and i keep seeing this in the part description for this damper?

I could be wrong but i think its pertaining to systems that run with the rest of the accersories that might be upgraded to 8 rib ie.magnacharger,kenne bell, etc. Systems that dont have a designated drive belt

The pulley will be fine the way it is if you are running a procharger style setup. Just bolt your blower crank pulley to it and go. Hope that helps
