I use the Pro Street balancer on 2 different engines including the eng in my 63 right now. I have not had any problems with them and I do race my car sometimes. Ron

The pioneer brand is made by pro-bond and is a good damper. We used to sell the professional products dampers, but after many failures we discontinued that line. We carry the pro-bond/ pioneer dampers in their place.

Okay, I'm the curious kind.
How does a balancer with an sfi rating (I believe that's 13,000 rpm)experience "many failures"?
Inquiring minds want to know.
BTW, I have been using a PP balancer for about 5 years on several engines with no issue.

I've learned the hard way.I bought an SFI rated balancer from Summit and had issues with the outer ring slipping. I did not realize it had slipped and reused it on my new build. We found out on dyno after we couldn't get the timing set. I wasted 1/2 a day on the dyno, my builders time, and potentially caused other damage had it not been caught. I guess my point is we all spend good money on machine work, balancing, internals, valvetrain, and even bling. Why not spend the extra $100-150 for a proven part? It cost me more than that in headaches. Call me crazy.....

Here's some first hand experience: I have made spacers for friends small block ATI balancers because they rub the timing cover?

I knew a guy who had one of the prostreet dampers..... outer ring moved on him........ how do you set the timing like that?

Like most offshore stuff..... the quality is hit and miss....

I have been running a fluid damper for over twenty years..... so when it comes to damper discussions... I have grown a thick skin.....

i have seen that brand come apart on a 383chevy. came apart and one of the pieces broke the outletfitting clean of the fuelpump also left a pretty substantial dent in the framerail. i wouldnt install that brand on a 318 destined to only run at idle.

---

and no there is no way in hell that was because of an installer doing something backwards. and it let go at less than 6000rpm,infact it never saw over 6000rpm,owner of the engine is very happy that his car did not burn to the ground thanks to that piece of absolute garbage.

I've ran the pro street balancer on 2 engines, up to 7000rpm and lots of street miles...No issues to speak of

"RAMM" (Jess Robinson) was running either a Professional Products or 440Source brand (possibly the same part, but he'd need to confirm that) damper on one of his BB EMC entries a few years ago when it failed during the competition. Ask him what happened.

Also, how about a performance machine shop that couldn't get a rotating assembly to balance properly w/ the PP damper installed, so they swapped it out for another brand and resolved the issue? They won't deal with PP dampers anymore.



I have personally seen 3 PP dampers fail, one actually blew right apart on the dyno ( BBC). That being said, these were all older units. They did have a propblem with the elastomer seal failing at that point. I have only used customer supplied ones since then, as I wont use them. The only time I will even allow that is if its a street engine.

I have also experienced, and have posted before, several failures with the Summit brand balancers. Customer bought one, and the outer ring slipped, he timed it accordingly, then shortly after tore the main webs out of his block. I was not impressed.

What happens when these posts come up, is no one wants to " admit" often times, they had a problem, as they know the " told ya so" crowd will be right along ( rightfully so). You'd be surprised at the failures of parts I know about from different shops and members on here, that never make the headline news....
