I think I would rather bet on a bonded one than the Romac's setup.

<edit> After consulting with GR, I've just ordered the S race one from www.minis.com.au

I couldn't let this gem slip without getting a mention. Well done sir.

mini7boy, PM sent.

thanks very much for your reply, Kevin.

I replied to your email, but my PM hasn't left my outbox so you may not have received it yet. My sent box is empty. Maybe they get batched by a mail handler?

PM's don't leave your outbox until the recipient reads them so it just means that Kevin hasn't been on and read it yet

I have now seen a Romac off a 1275 race motor with the knurled rubber strip hanging out the side.. it was not a pretty sight.

Hi mini7boy,

To answer your question, yes.

Graham Russell

Yep - mine looked pretty much like that.....

Fair effort that......
GR......
How long was it on the engine before it did that?
Did you pull the engine apart after you found this?
If you did pull it apart, were there any other problems that may have contributed to this happening?

Cheers Scott

come, come Russell. Get to the point.

Stop beating around the bush.

Time is money, after all.

How do you expect the poor thing to work when you've pulled its gizzards out? Them's the secret that makes 'em work......for a while. Now push them gizzards back where they belong and get back to racing.

Time for something like this, then??

But I dunno if anybody makes one for an A series...

I doubt that anyone makes one for the A-series because the market is too small. The viscous dampers sound good theoretically because they are claimed to work at all RPMs rather than just the "as built" RPM range of the elastomer dampers. This sounds good, but I don't know who runs the fluid dampers. I believe that most of the NASCAR guys run the ATI dampers.

Hi simon
The balancer was on for two meetings and no there was no
other damage to the engine.
When these balancers first hit the market we were one of the
first to use them, back then the outer ring kept parting company
with the inner ring so they then put the snap ring in the front to
stop this happening but they didnt fix the problem which is the
rubber between the inner ring and the outer ring.
Now in saying this there is another big problem its called the
driver,[ the guy behind the wheel] if youve ever stood at the end
of the straight at a circuit you see what i mean.
the arrive at the braking area , and as soon as they hit the
brakes they shove it back into third gear and let the clutch out
most of the time when there are no reves to match the down
change, and when the clutch is let out the reves go way beyond
any rev limiter this imposes a lot of load on the crankshaft
now the outer ring on the balancer wants to keep going when
the rest of the motor is trying to slow down and the rubber
can not handle this, nor can the centre main that why they
often brake.
You have to get your speed down before you change down,
BRAKES are for slowing the car down not the engine.
Now in saying all this i have used one of these balancers on
Greigs car when i first built his engine,but his engine is a short
stroke engine which changes a lot of the harmonics and
vibrations in the mini motor, in my motor being std stroke
ihave to run different valve springs, balancer, and flywheel
to Greig engine plus he does now how to brake and change
down gears.

Hi Kevin
When David Visard he asked me would i try the fluid filled
balancers he was having made at $500 a time, needless to say
they did not work, they lost 4hp over a std mk2 balancer (s)
NOW heres the funny part when i bolted these to the flywheel
of the mercury v6 outbord motor on the back of the ski race
boats they added 500rpm to the motor every time,
because the motors are mounted so high on the back of the boat
to get the speed, only one blade of the prop is in water at a time
( 3 blade prop) so as the blade is hitting the water its sending a
a shock wave, vibration, or what ever up the the drive shaft to
the engine, now for some reason the balancer was taking the
harmonic, vibration, out of balance, or somthing i dont know
about out of the engine,but it made a big difference to all the
motors i put them on. but on the outbord dyno it made no more
hp at all, thats a power head dyno not a prop shaft dyno
which is the only one in australia.
