High Fuel Mileage and Great Running Diesel Engines
The Power of letting the air FLOW! We talk about this subject quite often and continue to learn more about the value of fuel and exhaust flow while testing trucks on our new Taylor Dyno. For instance, our ported and ceramic coated exhaust manifold flows 20% more exhaust, lowers the exhaust temperature by 125, degrees and improves the spool up time of the turbocharger, along with a 0.25mpg increase in fuel mileage! What we have recently learned on the C-15 Caterpillar single turbo engines is that the manifold, when coupled with our High-Performance Cat Turbo, gains the engine about 100 horsepower! In the coming months, we will have concrete “before-and-after” dyno test results that will tell us EXACTLY how much horsepower increase these changes result in for EACH engine, but as for now, customer feedback has given us a pretty good idea. We are NOT adding any additional fuel; just eliminating restriction and turbulence. The net gain is 3.12 horsepower PER POUND of turbo boost. That is an incredible gain of power by simply changing only TWO items on the engine! Please keep in mind that these trucks that we test already have our high flow quiet performance mufflers, and most of them have the Fleet Air filters already installed. Every day, we get back reports from owner-operators that install the manifold and turbocharger at the same time and they tell us they have to learn how to drive their engines all over again because of the power, rate of acceleration, and responsiveness. During the Louisville Truck Show last month, an owner-operator told me he installed the Fleet Air Filter and our Quiet Performance Muffler on his truck and gained 1/2 mile per gallon. His total investment of $518.00 was paid off in the first two weeks of driving. So, what that means is that every two weeks, for the life of his truck/engine, he is going to make $518 MORE than he did before! When people say that they can’t afford high-performance upgrades, I think to myself “You can’t afford NOT to buy them!!” Again it's all in the flow of air, fuel, and exhaust.
Speaking of fuel flow, fuel lines need to be changed once they are about 10 years old: The rubber on the inside of the hose will swell closed, thus restricting the fuel flow. The best item you can install for your engine's fuel flow is the FASS (Fuel Air Separation System). During the installation, some of the fuel lines will need to be replaced, so just replace them all and eliminate the chance of fuel starvation. Diesel fuel contains between 3% and 10% air. The harder the fuel pump has to work to suck the fuel out of the tank and pressurize it into the fuel pump or the injectors, the more air it extracts out of the fuel. This air has to be compressed in the injector first and then the fuel second before ignition begins. This delays the timing and the ECM changes the timing every second and expects the injectors to inject the fuel it's looking for. However, the air comes first and now the timing is off. The ECM could compensate for the delayed timing if all 6 injectors received the same amount of air every time, but they don't. Why not just eliminate the air in the fuel by installing the FASS Fuel System? When running a FASS system, the fuel pump does not have to suck the fuel out of the tank: The electric motor on the FASS System does that job, along with eliminating the air and sending it back to the fuel tank and pushing the fuel under pressure to the fuel pump. The fuel pump LOVES the positive pressure because the hardest part of its job has just been eliminated: Now all the fuel pump has to do is increase the pressure and push it into the injectors. The net results are: The life of the fuel pump is greatly extended, the horsepower of the engine improves by about 30 hp, the fuel mileage improves by about 0.3 mpg, the throttle response improves, the INJECTORS LIVE LONGER (because the “tapping” effect caused by air bubbles at the tips is gone), the engine runs smoother (especially the BXS Acerts), and the pull of the engine is more consistent. That’s SEVEN improvements by installing just ONE item on your engine.
Please do yourself a favor: If you are bringing your truck into our shop, WRITE notes of everything that is wrong with the truck. DON’T try to remember everything! Makes notes: Take the time to write them down, because when you are standing at the counter and Gary or Pete are writing your work order, items are forgotten. Please write it down so our service department can better assist you. SO many times, we hear once the job is completed "By the way, did you see or notice that my fan or cruise control is not working all the time, or “My coolant temperature fluctuates." L We have now completed all of the repairs you told us were needed, but now there are more and the day is over.
Summer is coming and so it the HOT weather! If your radiator is old and just getting you by, please take care of it now before it's an emergency. Here’s something to think about concerning radiators: The first two rows do the majority of the cooling. The next two rows help some. If you purchase a 5 or 6 row radiator, it's still only the first 4 rows that do the cooling. This is WHY we install 100 tubes per row on a 379 Pete. The KW has a narrower hood and so we have even more tubes per row. It's the amount of tubes per row and the amount of fins per inch, and dimpled tubes that make a great radiator; not how many rows of tubes.
Another thing to remember: It is very difficult these days to keep EVERYTHING we offer in stock, and while we are VERY good at keeping a solid inventory, it is NEVER a good idea to wait until the last minute to order parts that you need to avoid unnecessary downtime. Preventive maintenance is absolutely KEY in this industry, and desperation is the root of many a screwup. Please know the last 6 or 8 of your VIN and your engine serial#. PLEASE give us an extra day or two when you are ordering parts so that if Fedex or UPS ends up misplacing something, you don’t end up waiting an extra day for the parts. Please don’t expect us to be able to give you exactly what you need 10 minutes before Fedex/UPS arrive to pick up today’s outbound. There are only five of us here taking phone calls every day, and we are averaging 1150 calls per week. Things get complicated all the time, so not having to get packages into the truck at the last second is a big help. We are a small, family-owned company, and we VERY MUCH appreciate the loyalty of our customers in these hard economic times. We will do ANYTHING we can to help you, but Fedex waits for NO man. So please try to anticipate what you are going to need. Thanks again.
