Balancers
My 455 has a Summit balancer on it, are these any good? The thing is very rusty and all the chrome is coming off. I have a balancer off a 428 and a 400 will either of these work on my 455? Thanks

hey, not to steal your post, but what you said about stock balancer made me think. I just bought a pioner balancer at summit,,, it was about 90.00 some dollars,,,,but would a stock balancer do just as well in a 463 with 500ft. lbs of torque, or are after market ones that much better?

A heavier balancer is better. Isn't the Pioneer basically a stock replacement? Don't know, never seen one but I thought Pioneer stuff was pretty much stock equivalent(?) The more expensive aftermarket balancers are almost all larger and heavier than a stock balancer, which is better for damping vibrations in high output engines.

Just saying "Pioneer balancer" doesn't say what it is. Pioneer has four lines of balancers- "Standard", "Premium", "Street Performance", and "Performance Race (SFI)".

At $90, it's the stock replacement. The "Street performance" unit is in the $150 range, and the SFI units are over $200 (Pioneer numbers, that is).
The stock replacement is a quality unit. It should be fine for anything under 6,000 RPM. Jim |

Why are heavier balancers better. Romac has a good reputation and has one an Ultralight Dampner at 5.45 lbs. Isn't lighter better, in quality units?

Buy an ATI, they are used by all the top race teams, you can't go wrong with that kind of reputation.

it seems most above stock quality aftermarket balancers dont just slide right on...need machining...

As I posted earlier, why not use the Ultra-light Damper from Romac as it barely costs more? Isn't lighter better, in quality units?

Dave - no expert here, but the heavier (stock weight) balancers tend to idle better. If you have a pretty radical cam and a very light balancer then you'll have a rougher idle.
To my knowledge the lighter balancers don't really confer much of a performance advantage. I could be wrong though. I just replaced my balancer with a pioneer - was called a high perf. street balancer (a little over a hundred bucks from Summit). It is not SFI. The stock replacement ones are under $100. Pioneer makes a SFI approved for 170 or so. One thing, you want to get a decent unit - some of the TDC marks can really vary. Also, it is nice to get one that has multiple degree markings on it (the pioneer I have does - the stock replacement ones, whether pioneer or whatever, do not - just the single TDC mark. I have been pretty happy with the pioneer and it did slide on pretty easy. Hope this helps. |

the less reciprocating weight the faster it will rev. I believe that is why the make the light weight balancer and light flywheel.

Thanks, "trans am ed",
The RPM factor sliped my mind. I think in the spring I'll get the Romac Ultra Lite. Thanks again, Dave |

Most people will tell you that light-weight flywheels are miserable on the street. A heavier flywheel give you more rotational inertia and is less likely to cause your motor to stall or require higher reving when starting from a stop. Light-weight flywheels are at there best with track cars that are at constant high rpms and need to accerate faster out of the turn etc. They are not meant to be driven in stop-and-go driving.
To a lesser degree I would think a light balancer vs. heavy would do the same. Jim Hand has a section in his book about balancers. |
