Thank you for the fast delivery, and the tech and secretary I talked to were both very helpful. I have it installed on my truck and man, the difference that it makes at an idle. Can’t wait to see what it does driving down the road. Thank you.

2006 Single Turbocharged ACERT

2006 Single Turbocharged ACERT

Installed an AirDog on my 2006 Single Turbocharged ACERT this week. -10° to 30° above zero had absolutely no effect on my typically finicky engine. Unbelievable improvement in all around performance. While I fully suggest keeping up on all bypasses and filters in a stock system for peak performance, this system is a no brainer for reliability and consistent performance from your Caterpillar engine. I’m beyond impressed with performance and also the ease of installation. Quality second to none!

We do all of our own installations at our shop in Kimbolton, Ohio. In terms of throttle response and engine idle, we have noticed better pick up and better pulls on the hills. We track fuel mileage and have had about 0.5 mpg increase. We have also noticed longer time period between filter changes and better start up in cold weather.

2002 T-800 Kenworth with Cat C15 Engine

Purchased Champ II in June 2020 and installed myself. Have noticed better throttle response, especially once the fuel got lower in the tanks – it remains constant. After 6 months, I have seen 2/10 of a gallon increase or roughly 4% increase in fuel mileage. I also noticed quite an improvement in power. I’ve told a few of my friends about it and since I took so long to see just how much it changed, they tend to believe me. I’m satisfied.

AirDog installation was a breeze and I can feel power gains in my truck. Just getting through my first tanks of fuel and will be checking fuel mileage. Thank you for the fast service and awesome product.

Last month (July 2020), I got an increase of about 18% but that can be due to tailwinds, light loads, or a multitude of things, but since I keep good track of my mileage and like to average it over a six month period or so, I’ll let you know in December just how much it has changed. So far, I’m impressed.

I usually drive about 125,000 miles annually and use about 29,761 gallons of fuel. After the AirDog was installed, my fuel use dropped to 24,038 gallons! My mpg pulling my Bull Rack before putting the AirDog on was 4.1-4.3, now I get 5.2 and have seen up to 5.7 with no wind and 70-75,000 lbs. Plus, my manifold pressure went from 27 to 33 psi and my exhaust temps dropped from 825 down to 650. The truck puts out less smoke and idles much smoother.

After some time of use, we noticed a loud growling sound that we thought was coming from the (AirDog) unit. We were advised to bypass the AirDog, then send it in for warranty. Immediately after removing it, we found out it was not the AirDog, but our factory Cat transfer pump that quit. Thank you AirDog for getting me home.

The AirDog lets my Cat C15 deliver the consistent power I need to haul quarter million pound loads – I depend on it.

With the AirDog installed, the results in fuel savings are 10.70%. The driver stated the truck is quieter, starts easier, runs smoother and has more power. His quote, “it makes pulling a heavy load feel like a light load.”
