TCI Rattler and ATI. For street-ability or wide RPM ranges the Rattler is better, ATI is better for more specific RPM ranges. IMO

This isn't the first post on this forum about the issues with the professional product dampers..

I am going to try and get this warrantied..it is only 4 months old. If they replace it, I sure won't use it on anything but a street engine. I figured it was a decent part since our pontiac vendors are selling them....NOT!!!! I will post some pics for reference in a little bit. Bill

here's a link to ATI and it shows how this piece of crap comes apart!!

Junk Design IMHO, Look at it all apart, Why cheap out on a 15000$ + engine???

PP is nice looking, too bad mine fell apart on the dyno. Replaced it with an 8 yr old BHJ, all is good.

Pioneer SFI balancer, $150 from Summit, 4 bolt Pontiac bolt pattern, tight slip fit/ no honing necessary.

I also run a pp and so far so good probably got over 100 passes on it this yr!.no problems. I loctited those little screws.. will check them tomorrow...

[BruceWilkie]

If they warrantee it see what they say about covering damage it could have caused had it failed when you were racing. If they cant reassure you ask for $$ instead of replacement. They shouldnt fail like that especially if it comes with no maintenance instructions or need to be loctited. Raise heck for sure(be a gentleman though)! I had one on my shopping list looks like I'm going to look into the Summit or just buy a TCI now.

[Ryche400]

Ive been using the "street" version for about a year now. Although, It rarely sees anything over 5K RPM. It looks just the like the one posted, except the red ring. It seems to be working fine, but like I said, not a race engine. I thought the SFI balancers arent supposed to have a rubber ring???

[Bnick166]

The Summit SFI Balancer is made by Pro-Race (www.pro-race.com). I guess Summit buys them in bulk and has them laser etched w/ their logo. They sell for quite a bit more on the Pro-Race Website.

[440GP69]

Yep and Jegs has them too, very nice for a steel damper, Overall the TCI and ATI are the best they really can't come apart But why can't they make em in 4- bolt pattern, it just seems it was an after thought and not designed from the ground up for poncho's

[500plus]

Well there is a 1 year warranty on this thing. I was told to send it back with a copy of their email for a free replacement...it will ship out Mon. If I get a replacement from them...I will just use it on a street engine that will not see 7k plus rpm or maybe sell it if someone is interested.LOL...Bill

[wrench]

Just curious, did the bolts loosening cause all the failures? Are they failing in other ways as well?

[Tom Vaught]

I remember when Summit used to sell decent stuff. Times have changed. Yep, I know, the customer is always right. If he wants to cheap out and buy a lower quality part, so be it. In the old days the respected owner in the speed shop would stay "Keep your money, stay away from that crap, and when you have enough to buy a quality balancer, come see me."

I Agree with Tom V.
I've been Building Performance Engine for 20 Years...I've Learned to thoroughly inspect the Parts offered by the Various Manufacturers and Draw My Own Conclusions..
My First Experience with Professional Products was about 5 Years Ago..

I was Building a 302 Ford for a 66 Mustang and the Customer was Running Short on Funds..The Price was Attractive, so I Considered Using their Dual Plane Intake Manifold..
" What a Huge Piece of Crap ".. Out of the Box & Right Back in the Box..

What Did I Learn about Professional Products: Cost is the Primary Concern and Quality is Far down on the List of Priorities..

I've Inspected more of Their Products Since & Still Not Impressed..

As Far as Summit Products..Don't Buy any of Their Anodized Fittings..
The Swivel Fittings that I've Tried Leaked Immediately..
( No Wonder They Swivel So Easily.)

I gots the "Made In Australia" PMD Balancer. It seems fine.

There is a recurring issue: the 4-bolt pulley gets red-rust at the 4-bolt holes because the 4-bolts seem to loosen every week. the 4-bolt pulley holes are now curved ovals. I stopped checking it 5 months ago.

Probably need to re-drill the 4-bolt Pulley, and use Clutch-fan studs. HIS

[Jeff V]

I had one come apart on me this season,luckily no damage.I now run the ATI I should have had on there from the beginning.I also know of 2 others that came apart on my friend's cars.If its a race engine get it off there before it lets you down.

[blaktopr]

So I guess for the guys like myself, loctight and frequent inpections are in the future for those who have one but not yet used it or had no damage yet. That until money comes up for a better one. Lesson learned. Thanks LMS for making me worry about my fuel system. Duel inlets and outlets, filter and pumps. Well I guess I will cross my fingers when I fuel her up.

[Formulas]

Anyone want to donate a used one to science thats not totally fubar.. I want to see how they are built and see if said screws could be upsized and up graded..??
