Harmonic Balancer

[njk53]

Thanks for the input. The reason I ask is the race car my brother and I bought has one on it and personally, I've never heard of them. I was filling out our tech card and they ask for the balancer make and when I looked the PBM was what we had. The engine is fairly fresh and was built by a well known engine builder. I cannot believe he would use this lower end product because the engine has all good stuff in it. What may have happend was the previous owner may have taken a good unit off and replaced it with a cheapie when he sold the car.
