Horsepower is horsepower?

Wilber1, yes you are correct that the little turbo gassers are killer when it comes to performance. Hoook a trailer to it tell us how it works out. LOL!

Also, take that same 2.0 turbo and tune it to it's max to run on pump gas. No engine mods just tune. Now take that 6.7 diesel and tune it to the max on pump fuel. See where your numbers are. The diesel is turned way down from the factory and the gas is running close to it's max from the factory.

Well you aren't likely to find a two liter engine in any vehicle towing much more than a pop up and even then it probably won't be because of the engine.

As far as tunes go, you can take that little 2 liter to a select Audi dealer and they will send the ECU to a company called Stasis. They will reprogram it and together with one of their exhaust systems HP goes to 270 a 23% increase, torque goes to 328 lb ft a 27% increase and you will still have your four year 50,000 mile warranty. How many manufacturer's offer that option with their diesel trucks?

All the diesels are 100,000 mile warranty......

How much warranty do they have if you install a tuner and boost power and torque by 25%?

Anyway, I don't want to get into diesel versus gas but trying to make the point that today's engines aren't our father's engines and many things we considered to be "truths" in the past, just don't apply any more.

Diesels are stinky and noisy. Right.

Well over 100 HP per liter on pump gas in your daily commuter. Impossible. Right.

Using 13:1 compression ratios running regular gas. Impossible. Right.

All wrong and you can buy them all at your local dealers.

I have personally seen warranty claims done with 50% increases. No receipts to show so believe it or not. Depends on what is being warranted.

Try running 100 hp per liter in a TV towing heavy on pump gas. Done all the time on pump fuel.

Back on the OP, hp is hp when it come to figuring how fast you can move a load at top speed but how quick and how wide of the rpm range you can make that hp is going to determine how fast you can get to that top speed.

Were these claims done with the manufacturer's full knowledge of what had been done with its engine or were they just smoked through by a complicit dealer?

I thought this was about HP vs HP. Because of present technology it's possible for a gasser to put out more HP and as much torque over just as wide a RPM band as a diesel. They just can. Guys need to get their heads out of the sixties and seventies. They won't be anywhere near as efficient and as far as reliability goes, it will depend on how you build them. If a 6.7 gasser weighed as much as a 6.7 Cummins, my guess is it would be pretty stout, but output would suffer some from all those heavy bits flailing around. Everything is some sort of a compromise.

There are stock diesels putting out 100 HP per liter but they are 3 liter twin turbo units in European performance cars. Not likely we will see them here any time soon. That's a shame.
