8.1 VORTEC MPG MOTORHOME HOW TO

The best ones in my opinion are the Ford V-10 Triton, the GM Workhorse (8.1L GM Vortec) W-20 to 24, and the Cumins ISX. The fact of the matter is, in most cases, both вЂњgassersвЂќ and вЂњpushersвЂќ have engines that are designed for trucks. That sounds like a win-win situation, too.So, youвЂ™re ready to buy a motorhome and all you can find on the Internet as far as gas or diesel goes isВ opinion, and in most cases, opinion that is not fact based! Well letвЂ™s take a few minutes to drill down to the FACTS! What are the key differences between Gas and Diesel RVs? Come to think of it, the new Banks PowerPack and Stinger systems for the Vortec 8.1L V8 not only last a lifetime, but theyвЂ™ll also pay for themselves over that lifetime. And in a big motorhome like a Workhorse, you know you could use some more power-especially when youвЂ™re entering an on-ramp or climbing a grade-and you definitely could use some help in the gas mileage department. Reduce any of these losses, and you both increase power to the driveshaft and you decrease the amount of fuel needed to make that power.

They lose power-sucking air in, compressing it, and pushing it out (pumping losses) through heat to the coolant through heat out the exhaust and to moving parts (friction and inertia). Gasoline engines, in particular, are highly inefficient. But Banks does it by increasing the engineвЂ™s efficiency. How can you increase power and increase fuel economy at the same time? That seems impossible for someone like me. It actually lowers the engineвЂ™s operating temperature, which both increases the density of the air charge for more power and reduces wear and tear on the engine. But the Banks approach-increasing airflow-does just the opposite. If you take the hot rod approach, with more cam and compression and ignition and carburetion to make more power, you have to expect a decrease in fuel economy, an increase in coolant temperature, such things as a rough idle and noisy exhaust, and general abuse of components in your engine such as bearings, valves, pistons, rings, and cylinder walls. And theyвЂ™re even designed to protect your spark plug wires (have you priced a set of those lately?).Д«eing a hot rodder, this last part is what always amazes me. If youвЂ™ve ever run regular exhaust headers on a vehicle-especially in areas where they salt the roads in winter and especially in hot environments like a motorhome engine housing, you know that they are prone to rusting and warping, which leads to blown gaskets and lots of noise. The PowerPack system also includes our stainless steel, mandrel-bent TorqueTube exhaust manifolds with machined 5/8-inch thick flanges for gasketless mounting. These are impressive numbers that anyone could claim, but we have accurate test data to prove it.

Behind that, our mandrel-bent, stainless steel, 4-inch diameter Monster Exhaust slashes backpressure a full 70% over the stock tailpipe. On the exhaust side, the Banks all-stainless, heat-shielded Dynaflow muffler (no, it doesnвЂ™t come from an old Buick we make them specifically for each application), increases exhaust flow-that is, decreases backpressure-by 65% overstock. It lasts a lifetime and doesnвЂ™t need servicing until 50,000 miles (servicing kit included). Both the PowerPack and Stinger systems include a Ram-Air intake filter to flow more and cooler air into the engine. More specifically, Banks uses the same methodology for achieving power increases in nearly all applications: more airflow in, more airflow out. But the news this week is that we now have Banks Power available for the 8.1L Vortec in the Workhorse motorhome chassis at both the PowerPack and Stinger levels. ThatвЂ™s why it always takes a little time for us to introduce new products for new vehicles. They did it the way we always do-by building prototypes and testing them exhaustively to see what really works best in the real world.

So how did the Banks engineers figure out how to get 22% more power out of it? ThatвЂ™s 66 more horsepower and 77 more lb.-ft. At close to 500 cubic inches, the GM 8.1L Vortec in the Workhorse chassis is already the most powerful gasoline motorhome going.
