Are there any "bad" balancers/dampeners to avoid on a BB engine? I'm in the process of building a new engine, and it will have a new bottom end. Since I'm starting from scratch, I just find it a bad idea to put a new rotating assembly in and use a 45 year old harmonic balancer on it. Using a 45 year old block is bad enough. What works, what doesn't, what do I avoid? Thanks

I'm trying to stick with a stock pulley layout for now. So there are none to avoid, or none better than others? I'll take a gander at the Trick Flows. Thank you.

I have had good sevice from ATI and Fluidamper. I tried one BHJ damper on a fairly mild 500+ hp 440 and it slipped the outer ring after about 6 months of use. No more BHJ for me.
Only bad thing about ATI is you better spray it w/ clear coat before you put it on. Otherwise you'll barely be able to read the timing marks after a year or so.

The harmonic damper on that Cummins engine Ram truck idling next to you at the stoplight is a Fluidampr. They're not cheap but they work. Avoid the knockoff fluid dampers.
Pioneer makes a good damper. If you think you're going to be racing, an SFI damper can save you money later.
Your friendly Summit catalog has several different dampers and all I have seen in the catalog are good. PowerBond is a Dayco product, that's top drawer.
For strength you'd like the outer ring to be either steel or nodular iron, sometimes called spheroidized iron.

The harmonic damper on that Cummins engine Ram truck idling next to you at the stoplight is a Fluidampr. From what I have discovered over the years, there are mainly two main designs, one is more effective at lower rpms, the other at higher rpms ( I see that point as 6K), and the amount of time in that range. At what RPM YOUR crank assembly has the most flex/harmonics, is likely based on a multitude of variables, and unless with F1 or OEM testing, you can only approximate with your final choice, which based on in the field use, that guessing must work OK. Good Luck.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

Big difference between a dampener used on a low rpm inline 6 vs. a high rpm V8. If Fluidampnr's were free, I wouldn't have one.

I have 2 on 950 horsepower plus Motors. 4 of them I have had over 25 years. Never a problem. Are they going to ruin my Motors?

I use a Pioneer damper from Jeg's. It's their house brand,but made by Pioneer. It fit well and the pulleys lined right up. Plus it's SFI certified,and wasn't expensive.
Nautilus Racing- We use Superformance gaskets and Turbo Action converters/products.

I have 2 of them on engines and been turning 8200 rpm for years.. I just put a third one on my 416 but thats only a 7200 rpm engine

Is the IW damper a copy of the Fischer damper? I could call and ask, but seems that's what it is. I've been using FD's since 1990 after a very poor discussion with ATI.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

Had a Pioneer on my last street wedge. Slipped the ring within 1,000 miles. No warranty coverage, either. Have a BHJ on the Hemi now. 1,200 miles and counting.........
Master, again and still

On my mild street car that see's the track only about once a year lately I have used this Pro Sport balancer I bought from Mancini. I have used them on three different street engines with no failures at all. I like that all my stock pulleys line up and it is SFI approved. I have had one on my 63 since 2008 and I drive it alot on the street. The ones I bought were all made in Austrailia. Ron http://www.manciniracing.com/prosport1.html

Dampers are one of those things I hear people say you shouldn't scrimp on, but how often do you see a damper cause a problem? I suppose the more RPM's a motor sees, the more you need to consider this piece (??). My 451 sees 6400, and I've never had a problem with this one: https://www.summitracing.com/parts/pfs-80013/overview/
