Another 416 Stroker Build-Pic Heavy
SO what damper do you suggest be used ? ATI Fluiddamper inovators and OEM are junk , what is left ?
Did I say Fluidamper and Innovaters West are junk, because I’ve NEVER said that.
I’ve said I don’t care what name is on the box, I refuse to use an elastomer damper, and I’ve articulated why.
They are used because they are cheap. They have a very narrow frequency range compared to other types of dampers. Chrysler spend a TON of money doing R&D on dampers and they say use a FD.
I can’t count the number of FD’s I’ve used and not a single failure. Not one. My Buddy and I are two of the most abusive guys I can think of on engines. We both run 4 speeds, he was shifting at 8000-8200 and crossing at about 8600, and I was shifting at 8500-8600 and crossing sometimes as high as 9000, and we both ran gear drives.
And not one single time did we fail a crank. And I was mag’ing the cranks once or twice a year, because all the ad reading stooges told us the cranks were about to fall out in pieces.
Not many on here can claim that, and do with honestly with a straight face. I can, because I did it.
Use what you want, but don’t tell me how great it is, or how junky an other than elastomer damper is.
The Damper that RAMM posted is a STOCK damper. It is junk.
I’d love to see how many of those cast cranks that failed had an OE damper, how many had an elastomer damper and how many had something else.
The overwhelming odds would suggest the majority of the failures occurred with elastomer dampers.
BTW, Tom Lieb, who owns Scat, tell you exactly why HE doesn’t use ATI dampers. It’s quite eye opening. And true.
And before you suggest every Pro Stocker in then country uses ATI, and every other swinging dick does too, the guys with the money have their own engineers do the dampers with their OWN rubber. Or, they have ATI build them to suit what they want.
I don’t have the money for that. And a Pro Stock engine spends very little time at an RPM lower than race engine speeds.
That’s one more reason they tow them back. If the crank hangs around at an RPM where the harmonics are not controlled, it will kill the crank on the return road. That’s a fact.
