15% underdrive accessory pulley for ATI damper

[Hpindy]

Hi everyone. I had one custom made for my car and the shop ran off a couple of more when they did mine . I really only need 1 so I figured I would sell off the extras I have . These only fit ATI dampers ( 10% O/D or stock size ATI). This is for the accessories only . It slows them down 15%. I have one on my car for 10,000 miles and over 50 pass down the drag strip . Zero issues . They are billet aluminum and hard anodized black . I can tell you what part number for the belt or I can supply it at an extra cost .

$150usd shipped for the pulley only.
Please PM with any questions.

The question is, how do we know we will get the pulley if/when we buy it?

You’ll have to trust rely on the quality of individuals that own hellcats and found this forum. I know I wouldn’t stake a long-standing reputation on 150 bucks and I doubts any of the other 1000 founding members would either.

I get what you are saying . That's why I use PayPal goods and services so we are both covered . I have many references on both sites if you want .

No issues here with this seller.

I mainly brought this up to bump his pulley thread, to start a conversation rolling.

I think the 15 percent UD pulleys are the cat's meow, and a dramatically underrated part of (especially high-revving) performance engine.

Dodge agrees. The accessory drive is already underdriven more than with the other Challengers in the Hellcats.

The thing about reducing parasitic drag is that it always pays off, every moment your car is running.

I agree with you . I have tried other ratios but 15% gave me the best results without negative side affects . Im super happy with it .

How much HP gain at max R’s you estimate it may net?

 

[Hpindy]

I'm comfortable in saying 8-10 rwhp . I had the ATI 13% underdrive on my 2010 Srt challenger and on back to back testing I picked up 8 rwhp an 15 rwtq. Same dyno same day . The big benefit is people revving their engines higher then stock . It will save wear and tear on all the accessories. Plus if you are a guy like me I believe all the "little things " add up .

Yea, Doing the little things have added about 60 dyno proven HP so far to my original 2.85 and 1050’s set up. Trying to get to 850 wheel without more boost as on 93 at 16.5 lbs I don’t want to risk more boost to get there. It’s about time for a new accessory belt as well. Now be a good time to change it as well, I’ll take one. What belts it need?

Can't say I ever bumped a thread by questioning the thread starter as a possible thief

Nix that request for one, I reread and now see only for ATI dampers, I’m running stock damper yet

 

[Mean Cat]

Very interesting !

Correct . The factory damper is a one piece unit . This only fits the ATI because of its bolt on accessory pulley .

It says ATI or stock.

 

[Hpindy]

It says ATI or stock.

Thank you for point that out . I edited and the original post . I ment stock size ATI damper. It only works on a ATI damper due to the bolt on accessory pulley .

So to clarify 10 % overdrive ATI or stock size ATI only.

Between the two sites, we've only ever had issues, that I recall, with one long established member.

So while anything is possible, the risk goes WAY down when you are dealing with "known" members. Too many of us know each other out there in the real world to be screwing someone over.

You might find yourself on the wrong end of an ugly-stick as you're walking through the pits.

I haven't met the OP in person, but I'd buy from him based on reputation.

Certainly when talking about a couple of hundred bucks.

 

[Kat von Himmel]

Oh, I already did.

Ah, yes, but you never know if/when such a gem will be available again, now do you?

That was my mindset when I ordered one. I don't mind sitting on some gold until I get the ATI damper. Heck, I might get a couple ATI's: an OD and a normal one.

But, until then, my UD accessory pulley is OTW.
