I guess you've never lined up against one of the many Supra single turbo I6 powered pro street cars making 2000hp and running 6 second quarters...

Njawb - I have no way to get hard data, I won't lie to you.

The two good V-8's in truck operations failed horriably with a standard trans. The 8.3 DD did well with an automatic trans in a truck, shifting gears killed it - why - I don't know????

The Toroflows I think were just a bad design, again in a truck no-good yet as a higher horse marine engine they were pretty good.

Isotta vs I-6, can't tell you why they failed, just they did, the engines had problems. They may have not been real "engine" porblems as much as accessories like turbos or pumps????

I wish I had real data to give you other than what the end results were, which I know are in-conclusive???

I was wrong and your right stirling the Isottas were V-6, I may have implied V-8. And yes, they were 800 plus Hp, from what I was told basically a stock engine with big fuel & turbos.

I don't know the pump number but you can do alot with the Bosch pumps.

I don't know of a hard way for us to prove this either way.

I will throw in one more big V-8 that you guys should know which again was a disappointment the Perkins or Rolls Royce V-8!!!! Big iron, no power and didn't run long between overhauls, again why???? On paper another great engine that should have set the world on fire, but why not?

With 2-1/2 times the displacement and a TBO of one full power pass. The Hemi is more powerful.

Scania V8 16,4 L 620 hp 2600nm or 1925 lbs/ft max

MAN 16 L 680 hp 2700 nm or 2000 lbs/ft max

out of the box power

those are three popular trucks overhere .the MAN is the most powerfull engine ,next year Scania comes with a 700 hp V8

I work on these truck every day,one guy has a Scania V8 he weight empty 65 ton ,fully loaded 175 ton ( with a 110 ton dragline on the back 110 ft long total) and he kick azz with that thing

I can,t post here ,if I could, I would post a pic of that monster truck combo

The line 6 ,s are for light duty (thats what the truckdrivers use to say here )
Lot's big flashy Euro trash horse power numbers. Aka " metric Horse Power". A Cat C-15 15L will put out 625 hp @ 2050 ftlbs and thats "SAE Net Horse power" (J1349). Thats "as installed" horse power not "stripped down Euro dyno mule" horse power. Thats 745.7 Watt mechanical horsepower not 735.5 Watt metric horsepower. Thats with MANY documented cases of "Million Miles TBO" never heard of Euro trash engines doing that! Now if the Europeans would dyno their engines "As installed" and use real "Mechanical Horsepower" ratings I would quit calling them "Euro Trash"

Funny that you mentioned Isotta Fraschini,I have one overhere , its a ID 38 6V SS Isotta Fraschini V6 9,7 Litre 450 hp at 3100 rpm, its a twin turbo ,twin intercooler,year 1986

I don,t have a boat for the engine yet ,I am trying to find a 26 ft hull , I saw a video from Apache /Aronow some time ago ,and there were 3 Isotta,s in the back ,exactly the same engine,s ,does anybody know anything about that ?

I spoke to a guy in the UK ,and he said those Isotta,s were doing around 850 hp in the late eighties ,with bigger turbo,s and pumpsettings ,and injectors .

This engine has a HUGE bosch line fuelpump mounted in the center between the cilinderheads.

Joe ,can this pump modified to support the fuel for that horsepower ?
180,000 to 200,000 miles per year thats a solo driver here in the U.S. Teams can run over 500,000 miles in a year.

Agreed in the American truck market the ISX & ISM series engines are the bottom of the heap. CAT C-15s and Detroit Series 60s way out sell the Cummins. One question? Why did you choose the weakest engine on the American market to pick on?

Back to that stone age!

Hey Joe,

Remember what that Chinese Dude said about " If you sit beside the river long enough you will see the bodies of your enemies float by". If you sit in these blog threads long enough you will see old technology come around again on a new engine. Detroit has gone and robbed technology from the Curtis Wright R3350-TC for their new DD15 engine. Get this Detroit is claiming they can scavenge 50 hp using turbo compounding. Wonder if we could just stuff a Napier Nomad in a Big Truck

29 firefox,

I enjoy everyone's remarks on here, yours as well. I even say some outlandish things from time to time!

500,000 a miles a year, can't be done. In a perfect world a OTR can avergae about 45 mph, that takes into account fuel stops, drivers eating, maintenance, loading and unloading.

@168 hrs per week that is 393 miles a year (perfect world), factor in logs and a little more than half that is all you can actually put on a truck. Even in the old days, 300,000 was monumental and could only be done by certain teams never a company effort.

I think we all got off track here including me and need to remember this is a boat forum and we should be discussing boating issues.

We're all just talking to talk at this point, one of us (me included) or a group of us should get off our a**es and start kicking some gas engine butt like we know we can!!!

Let's take a vote!!

What engine would we start with if we could put a project together today?

I'll start a new thread for this.

Have it your way, then: The MAN 16l V8 has a better horsepower to displacement ratio than the Cummins ISX, CAT C-15, or Detroit Diesel Series 60.
