ATI on all my power and higher end builds, Powerbond SFI for everyday bracket and street/strip builds.

ATI is proven stuff that is available, very adaptable and flat out works.

I bought and used a Fluid Dampener on my 528, 4.375 stroke. I bought and used a ATI on my 512 (4.250 stroke) street motor and again when I switch cranks to increase the compression on the 4.3 stroke crank. I have now decided to only use ATI on all of my motors, steel or steel and aluminum ATI all the way

heres some good info from a crank company:

"2. DAMPERS WITH MOVING INERTIA WEIGHTS
A. Fluid, balls, springs, inertia rings with rubber O-Rings, etc. Can
you balance a wheel on your race car if the tires are flat???? How
can your rotating assembly be balanced if to quote one
manufacturer, “These units (Dampers) should not be on the crank
for balancing as the inertia weight may not be centered until the
engine starts.” NEWS FLASH!!!! Centrifugal force will always take
the inertia weight off center no matter what RPM. Your assembly
is never balanced. TELL TALE SIGN!!!! Metal transferred on nose
outside diameter and damper internal diameter . . . A fatigue crack
starts. SNAP!!!! The crank breaks"

What's the deal w/ having to use spacers or whatever to make sure the pulleys are all aligned when using an ATI damper? I've never been sure exactly what the deal is w/ that...

ATI, here aslo!

I was told by a well known engine builder that the ATI is the best damper because they are accurate throughout the rpm. Fluid Dampers are good for low RPM, Diesel engines accually. Some diesel mfgs run fluid dampers on their OEM engines. My machinist spun my old Fluid damper for my 360 build, and he told me it was wacky, would spinn up ok 1 time, then be way off the other time, then be only a little bit another time. I bought an OEM 340 damper for it, and it was nuts on. For my 408 build, I did a bunch of reserch, and the ATI is what I found was the most accurate.

I have an ATI on my Hemi, I found the damper was farther out than a stock damper, I had to fabricate a mount for my alternator anyways so it wasn't a problem, but the waterpump pulley had to be spaced out from the front of the engine... I have elephant ears and I think I used a 1/4" or 1/2" spacer inside the waterpump pulley, can't remember which....

I have had fluidampr and ATI, only problem with ATI it needs to be rebuilt every other year if making under 900 hp or every year if over, Elastomer breaks down. That is realworld results and also what ATI will tell you. John
