Turbo the Ford V-10 in my motorhome ?

I am also just thinking of a performance throttle body, spark plugs and performance coils, its a 2007 3 valve v-10 with the Banks system but just trying to see what I can do to increase the HP/Torque even more.

Tons of performance mods for the newer sport cars but the motorhome chassis seem to lack in those areas.

Cheaper, far less complicated and more reliable to just change the axle gearing to a lower ratio (higher number). Gearing is a torque multiplier.

400 lb-ft motor x 4.10 gears = 1640 lb-ft

400 lb-ft motor x 4.88 gears = 1952 lb-ft

That's an increase in rear wheel torque of 312 lb-ft.

I doubt you'd see a 300+ lb-ft increase in torque by turbo'ing the V10.

That does sound great but that also keeps my RPM's higher, don't want that.

My understanding is the 5 speed trans is also installed behind Fords diesel truck and they have much more torque so the trans should be no issue.

I wonder if the same clutch packs are used in both. They may look the same on the outside but things could be a lot different inside.

I worked in engineering for a number of years with farm tractors. We had a transmission used on 110 through 180 hp tractors----all in the same housing and with same speeds. The internal parts were significantly different.

Easy to burn holes in the pistons if you get a lean condition. Better find a tuner that knows what they are doing with that motor. Say adios to the MPG as soon as you put your foot into it. Power costs fuel.

If you add twin turbo and low boost, maybe. Mileage, lost if you put your foot in it at all.

Cost, headers, new injectors, computer chip if available, internal engine parts, and heads if available. Save your money and put in a diesel and build it up. Cheaper and more power.
