Check your Harmonic Balancers Kids!

I used to go through a balancer every year. I don't think they stock ones liked the RPM. I was replacing mine with old used ones and that could have been part of my problem also. I swapped to an Aftermarked one and haven't had any problems since.


Good to see you caught this before it came clear apart! :nice:
 
Couldn't even guess the amount of threads like this one have come across
here over the years :crazy:

Yes ... higher rpm's can kill the OEM hb :Word:

I lost mine :(

after some high rpm datalogging working on my WOT fuel ratio

wuts a good brand aftermarket one to go with?

If you wanna go to a really nice SFI hb

I have been real happy with my Pioneer pn 872030 :banana:

No install hassles like with Romac :nono:
No spacer needed also :D

A quality part for sure :nice:

I been running one since early 2003 with no probs :)
and
I spin it up to just a bit more than 6K on occasions too ;)

AFAIK, even non-fluid SFI balancers use an elastomer. They tend to have a better build-quality (better method of elastomer introduction - not press fit). The rings are indexed and even secured together with additional means.

There still should be an elastomer in there though.

x2 - when I went 331 my builder included a balancer in the engine build. It's not a Pioneer and I wish I had one like I did on my 302. I had to use a spacer on the one I have now. :( The spacer is rated as high as the balancer, so what's the point. :nonono:
