Why not put turbos on 2500 gas trucks

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.

Aftermarket superchargers are available for most all the gas engines.

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

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)

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

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.

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.

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.

Turbo would just be a patch before the electric hybrid power comes.

I was just talking about this at work today. I think a small V-8 wit ha turbo would be ideal. Maybe a 4.7 or 5.0 with 400-450hp, and 450ftlb or torque would be a great motor when you don't want to go all the way to a diesel.

It's proven in the 3.5 Eco-boost to be reliable, powerful, and economical. You get the fuel economy of a 3.5 when unloaded, but you've got the power when needed.

Honda did the same on the CR-V we bought my wife. Went from a 2.4 to a 1.5 turbo, and increased power and fuel economy.
