AirdogII 165 or 100?

[Dirtdogg118]

I bought a AirdogII DF-165 a while back and I'm getting ready to have it installed, when I decided to read a little on the Airdog website. According the the FAQs on their site,the 100 is for up to 500HP, and the 165 is for up to 800 HP. It says the 165 may do damage to a truck having under 500 HP. Now my truck is mostly stock with the basic mods(cold air, exhaust, EFI live), maybe pushin 400 HP on the highest setting. Is the 165 over kill and am I going to damage my injector pump by running it? According to their website I will in time! Anyone heard of any problems running a bigger than needed Airdog system? Also I thought the AirdogII has a adjustable PSI setting to account for this?

the 165 for sure then. you'll love it, best thing ive done to my truck, runs so much better with it

I dont know how it could, you have a adjustment for your pressure and whatever isnt used by the engine goes back to the tank through the fill spout. I had a 165 in my lly and i didnt notice any fuel system reliability issues.

Yeah I've wondered the same thing OP. So a while back I called Airdog to ask about this, and when one of the "engineers" called back all he could tell me was that using too high an application might "blow out a seal or something".

I keep putting off getting a lift pump because I have just a moderate tune and I keep reading about reliability and customer service issues with both Fass and Airdog.

Thanks for the input guys. I sent an email to the Airdog tech dept asking them about the comment in their FAQs section. Haven't heard back yet. I'm kinda wondering if they mention that as a disclaimer in case anything does blow up! Still its got me nervous!

Yeah, please make sure to let us know their response.

Unless you plan on going up quite a bit in power, you can easily go with the 100 and be fine. It will be cheaper and the install is just as easy... I believe that the 100 will do exactly what you need... (presuming you aren't talking bumping the power up a lot later).

Right, but OP's question is he already has the AD 165 and is nervous about installing it because of his moderate (under 500 hp) tuning.

Sorry, I ended up going by your last post on "holding off on it" and mistook it for the OP! If you already have it, I would just turn the pressure down on it- if you are down to about 5 lbs, that will help tremendously (I think too that they are trying to be a little over-cautious as the AD's will return whatever isn't needed, so it's not going to run the full 165 gallons per hour through the motor if not needed...). You will still have the filtration, and the positive pressure going to the CP3 and it doesn't have to suck...

Thanks K9duramax! I think I'll re-study up on Airdog's website and see if I can satisfy myself that it won't cause problems (I am aware of the benefits).
