was hoping to keep my crank in one piece this season....

anybody running a fluidampr or ati pulley on a full drag setup? if so how do you like it? any other brands to consider?

 

I've used both many times

 

how did the two compare?

 

Sorry not either you posted ...

I run a Professional Products dampener (didnt have the money for ati) ... ran for over a year now and no problems. Think it cost half of an ATI and its SFI certified (18-1) and spun tested to 11K i believe. So it isnt tested as high as the ATI but I dont ever plan on reving that high thats why I got it.

 

the professional products dampener is about $200.

 

where do you can i find a professional products dampener. i would really like to run a dampener but not ppay 360 for one.

 

This is why we chose ATI over all others

ATI

 

thanks for all the good info so far

i checked out proffesional products site, doesnt look like they offer a pulley for h series.

i had called ati several months ago and found that they dont offer an off the shelf pulley for h series either. but they did say they could make one custom, for over 500.

fluidampr has them in stock for h series for 350. they say the pulley itself has a 90 day warranty but the viscus fluid inside has a lifetime warranty. and they claim the fluidampr works at all rpms.

as far as ati, some of the ones i have seen supossedly need to be tunned to any given engine by adding or removing the elastic bands. is this correct? if so, how do you go about tunning it?

has anyone ever seen a fluidampr pulley go bad? bearing inside, or fluid itself?

 

How much does the ATI run for Earl?

 

350-400 for and ati ... about 360-370 on average plus shipping is what I have found in the past. Got my professional prod. for 180 plus shipping.

 

need a h22 unit also but has to have the chevy bolt pateren on the front for the peterson oil gear this is the hardest part ive been looking for and even ati was confused when i called them for this unit

I think, in reality, the Fluidyn and ATI are equal to around 7000rpms and then the ATI becomes much better.
The ATI is around a pound lighter.

i will check w/ him.

 

I spoke to ATI at A show about the H22 and the said it would just be a manner of them maching A center hub for it (which they said they could do)and the outers are universal. Just ride over there they are local, off security blvd.

 

I run a fluidamper.

Jim Justice, one of the premier engine builders, did the testing for fluidamper and he runs it on his engines he builds. Look at Jim Justice's record for the engines he builds and his customers: Jason hunt, Brian Ballard, Paul Effanits, Richie Gibson. All these guys are the top of their game because of their engine builder, so his opinion must mean just a little. You think? Jim Justice has an engine dyno where he tested them and he wouldnt run junk.

Run what you want, but I still run and sell fluidamper. BTW, you can get the fluidamper from Jim Justice too.

thanks for the info everyone...very helpful

 

Hmm...this is some good information. Does anyone sell an effective balancer for a D-Series motor?

 

Also forgot to add that they also said for the high hp applications that they where having A problem with the outer part of the pulley slipping and rotating on the inner, due to the rubber o-rings that separate the 2 and you would have to send it in to upgrade to larger o-rings to eliminate slippage. So I don't know how your going to tell when this is happening unless you have to check it all the time but for NA it would be good.

I would get the sealed no maintenance fluidamper.

found out fluidampr is supposedly a press fit, not too fond of that idea but giving it a try anyway

anyone ever try opening the center SLIGHTLY ? yes, it has a keyway

 

I wouldn't open it up, it would kind of defeat the purpose of allowing it to adsorb all the harmonics with not being A press fit, it's not as bad as you think. You can put it on with the crank pulley bolt.

 

i was more worried about pulling it at the track if need be.

makes sense not to alter it though

 

ATI and fluidamper are both press fit.
