7.5L Ford MH: PowerPack

2008-11-06

It performed very well for us on our trip to and from Alaska...

The Banks system we purchase in 2006 for our 1997 Rexhall (Ford 7.5 liter V8) performed very well for us on our trip to and from Alaska last summer and continues to do well.  We are very pleased with the added power and, when I can control my right foot, added fuel economy.  Have not had to tighten a single bolt, nut or anything.  I read a lot about alternatives like Thorley and Gibson systems on some of the RV forums, but can truthfully say that, if people could experience the quality and performance of a full Banks PowerPack, they would realize the difference is more than just price.

Thanks again -  A very happy customer.

Class A Motorhome 7.5L PowerPack

Would not have made the pulls without the Banks system

I own a 1993 class A Pace Arrow 35 V on a Ford chassis with the 460cid gas engine. My wife and bought this unit in upper Michigan last fall and drove it home 500 miles towing my car. To say the performance and fuel economy was lacking is being nice. It would routinely drop 10 or more mph on the slightest hill and downshift constantly while getting a whopping 6-6.2 MPG @ 60 MPH.

Being a mechanic, I checked the entire powertrain to ensure no problems, which there were none. Upon research, I found this is a common problem with this chassis due to poor design on Fords part in relation to the air inlet and exhaust system. I did a lot of research on how to fix this problem and found that the Banks PowerPack and TransCommand were the recommended choice. Although pricey, I did purchase the PowerPack and TransCommand in early 2009. I installed the system myself in March. I relocated the air box to reduce the inlet roar caused by removing the silencers in the inlet tubes. The system installed without any surprises and all the parts needed were included in the kit. That is a rarity with most things. It is a very well thought out and engineered kit.

My family and I took this motorhome, with a car in tow, gross weight near 22,500 Ibs, on a vacation to Yellowstone and Colorado in July and I must say the difference in performance and economy was stunning. I was able to set the cruise at 65 MPH with very little drop off or downshifting on hills, while averaging 6.75 MPG for a 5000 mile vacation. The fuel economy ranged from 5.9 MPG going over the Powder River Pass (alt.10,900 ft) in Wyoming to 7.9 MPG on the flats in western Iowa. The performance gain and powerful sound of this system is worth the cost alone. I truly believe we would not have made the mountain pass pulls in the West without the Banks system. I recommend this system to all owners of this type of coach.

Thanks- A satisfied and happy customer.
