Called in to order a ATI race Dampner and the guy asked how much power i was making. My Build should be around 500-550 Horsepower and he said that he could sell it to me but no type of product warranty would be honor'd since i am making more than 300 HP.

I looked on ATI's site and it does say on there that its not to be used on a motor making more than 300 HP.

Does anyone know why ATI is saying this?

 

In for info over 600 hp on mine

 

i have seen 887whp on one. I'm actually in for info on this also. Since i have one on my motor and will be tuning in a few days.

 

Was he referring to the aluminum or steel hub version?

 

Thats odd since most of the guys making 600+whp order the race damper.

 

yeah, that is very strange

the race part # is 918471
street part # is 918476

i have personally used the race ones well over 800 WHP and many on H-T are doing the same thing

those are both Steel Hub Part #'s

They do have a aluminum Hub Part # that i would stay away from that the rep may of not had confidence in over 300 hp

there is some misinformation or confusion somewhere

ATI dampers are just fine on extremely high horsepower engines, in fact i think they are a great investment to get your oil pump to live longer

 

No Problems here on many many 800+whp builds we've done.

we have also used the 918471 steel hub.

yea i remember the horror stories of the aluminum hubs rounding out. but when i went to buy it they said nothing over 300 HP for the race pulley. and Nothing over 500 for the Street version. just didnt make sense so i figured i would ask around about it.

 

I am in for info. I have the fuidamper race and i hate it and on my new motor i was going to use the ati.

 

I know its a little off the original topic, but why do you have the fluidampr? I am in the process of deciding which balancer to buy for my new setup, and I am interested in peoples opinions...

 

The fuidamper atl. pulley is under driving way to much and up top at high rpms the atl. does not want to charge good. I even tryed to put a smaller pulley on the atl. and it did not help. I think it is half the size it shoud be.

 

Gotcha. Good to know. Thanks

 

Is the 918471 under driven on the atl. anyone.

 

ive been using ati dampners for 20 years in everything from import to domestic havent had 1 prob.. fluidamper on the other hand....not so much...

 

I have an ATI on my car. I think it makes over 300whp.

I dont think that they sell the aluminum anymore.

 

why would anyone consider buying one if they are making UNDER 300hp?
I understand thats a shitton of NA power.

whats next, 7K rpm limit?

 

lol i dont have problems and i run the street version 800+

 

We went 125 in the 1/8 and 154mph in the 1/4. Not sure if the car is making more than 300whp

 

off topic: when should some one switch from a stock pulley to a damper type pulley? Im going to be getting a good deal on a used on, but my set up is pretty stock for right now.

 

and what wrong with the fluidamper..why not run it over the ati..also what the advantages of the street version vs race..dont they all damper harmonic vibrations..

 

Replacing your stock OEM damper with an ATI even right after you drive off the showroom isn't a bad thing.OEM dampers have limited dampening capabilities vs ATI's especially at high RPMs Hondas see.
