fluid dampner on circle track engine

[juice87]

i have a new engine going together ati rattler is bad engine builder wants to replace it with fluid dampner? it has all light rotating ass. callies xls magnum crank and billet rods. what dampner would you use.

[3barz]

ATI all the way!!

[fast_crew]

NO FLUID dampner. Agreed ATI super dampner, too much money on the internals to put a junk balancer on it..

[giffordracing]

TCI makes the Rattler F ..ATI makes the Super Dampner A+

[powerslide]

yeah the rattler is junk. it broke the snout off a good callies piece we had. Couldnt convince the driver not to put it on when the old ati had problems he found out how expensive a new crank was.

Anything that is supposed to be balance as closely as a rotating assemble is should not have something boucing around in it JMO JMO

[TBRE]

Bingo.
The Fluid Damper, Rattler, and Gap-Less rings, all work better on paper, than in the real world.TB

I agree with T.B. 100% Bill

[juice87]

so Bill Hendrens what would you put on it callies magnum xls 36lbs crank and lunatti billet rods and j&e pistons. also small bert fly wheel if that makes any differnce

[Hendrens Racing Engines]

We would use the ATI its the best out there.Bill

Had an imca late model motor on the dyno with a litewieght 283 balancer on it.Tried a ATI balancer,it was close but the ATI lost 2hp.

[fast_crew]

Never see or feel 2hp on the track (was this consistant or just a one pull comparison, by the way? ) I am sure the crank would be happier with the ATI super dampner.

Did you use a light weight ATI so you were comparing apples to apples or did you compare a light 283 and a standard weight ATI?

[RCJ]

I didn't write the wieghts down,I think it was just under 5lbs for the 283,around 8 for the ati.Any changes that didn't go as planned we made second pulls on, the results never changed.
