Why not put turbos on 2500 gas trucks

I hear all these great reviews on the Eco-Boost engine and all the power it creates. Somewhere I read a few years back it had more HP and torque then my 2500 HD gas. Why doesn't Ford or Chevy offer that engine on a 3/4 ton truck or put the twin turbo's on the V8 gas engines?

    Fuel mileage is a big reason, na gas engines pulling a load get about 8 to 10 mpg, if you put a turbo on it likely drop to about 5 to 8 mpg.
  • My gut says COST ! 3/4 and up are sold more to construction companies and farmers/ranchers. These folks are very cost conscious. Turbos get you power, but at a cost. Also, many people still question the reliability of both the turbo unit and the boosted engine.

    I highly recommend. 500rwhp is at your beck and call. Write the check.

    Would he running a risk of Voiding any warranty?


    THAT goes without saying...

    And... modern gas motors and trans have proven VERY amendable to power adders without any ill effects. I know the Gen IV and V Chev motors have proven VERY reliable with superchargers.

    Your point is well taken however. Buyer beware. Risk and reward.

  • yeah turtle, back when I was around those Vehicle Tank Recovery (VTR) vehicles. At the time they had a V 12 Lycoming with a big turbo on each bank. It has been noted that when those babies were out of tune and towing a 50 some ton track vehicle they could pump out 1 mile per 5 gal of gas. :R
  • In three words; Duty cycle and heat.

    Turbo's put out a lot of heat any they make the engine put out a lot of heat. At 14 pounds of boost they are doubling the engine size. So if you have a 6 liter N/A engine you now have a 12 liter engine and it's hard to keep a 12 liter engine cool running full tilt pulling a hill with a heavy load.

    Then there is the fuel economy issue. You now have a 12 liter engine using 12 liters worth of fuel. A 12 liter engine can use a LOT of fuel. My 9 liter engine can use about a gallon of fuel/ 1/4 mile. Or 4 gallons/ mile. (no, not a typo)

  • Probably because the driveline won't take the power without extensive modifications.

    You can buy a 'hairdryer' for just about any powerplant but you always have to modify the driveline too.

    A slippery and often times expensive slope.
