Catmando we think alike about the Duramax 6.6 installation.

But Gale Banks used Carillo Rods and a Custom crank (LA Crank or Moldex ...don´t remeber that now) made his own "intake" used Twin turbos etc ...and took 100hp per liter out of it..now thats a higly tuned SuperBike number from the 80´s.
He admitted that 650 was about as high as he wanted to go without risking Too much durability.
With stock bottom end a 6.6 would tops in my eyes at 500 to be warrantied.

Now to your last idea...are you ready to gather the pieces to fulfill that project... surely a mechanic will show up ; - )

There´s already those tuning modules ready for them Yanmars, in Europe.
Regarding Scanias V8...well If you´re familiar that their marine verion is rated nowadays at 800 (used to be 850) plus Scanias Reputation as a diesel engine maker you wouldn´t ask.
A former Scania marine mechanic that I know told of specs for a 1100hp version (not generally available)

@ 100hp/liter in pleasure use isn´t that hard nowadays for some manufacturers.
Seatek and Isotta Fraschini are giving that with warranty..and you might find "emergency" Mil.spec ratings quite interesting on other makes.
Remember Diesels are rated at many different ratings.
From pleasure to commercial heavy duty to those ratings not given out to the public (law enforcment and military).
I remember when I heard of our Navys missile boats having two different top speeds..that which was given to the general public and the hush hush...

And diesels are Always Step tested in a Dyno not sweep tested that Gas engine manufacturers use as Advertised hp.
When you look into those same engines Commercial ratings you might not find it funny...because some gasoline (almost everyone) high perf engines wouldn´t even get a rating as they´ll shred to pieces in the process.

But why isn´t anyone talking about Audis V10 or V12 Tdi´s ???

I don't know how the auto manufacturers in Finland operate (are there any in Finland?), but here in the states, we don't use a sweep test. Only the aftermarket, and they aren't auto manufacturers.

Also a "tuning module" would not constitute an engeering durability test.

And regardless on Scandia's reputation, yes, I am asking, because unless they like to throw money and thermal efficiency away, they wouldn't use the same parts on low horsepower diesel as they would a high horsepower one.

And I guarantee the diesel tuners here will be all over those motors. There's already a module for the 1.9L VW motor. I drove the Jetta TDI and it was a blast! Only 100hp but almost 200ft lbs torque so it was very quick, especially out of the corners where I could keep it in a higher gear than a gas motor would need so more speed. Very addicting!!:drink:[/QUOTE]


Bought two of these Jetta's, one was gas and the other diesel. Sold the diesel for what we pd for it after a year and 18k miles. Put a for sale sign on it went to the supermarket, guy bought it right there on the spot, talk about timing. Great cars, never had or to this day have any problems with these Vw's.

Vw did already 7 yrs ago a 1.9 TDi Golf Road Racer that had 220+hp...it proved to be faster than the regular under 2 liter equivalent racecars at the time.
*Got Banned:-)
those TDIs put nowadays300+ft.lbs of torque with reprogs.

Not True that Europe is ahead in Diesel technology. Remember Detroit diesel was 1987 the first to use Electrical injectors in their Series 60 engines.
Cummins injectors and ECUs are used in many European Big Rigs.
Scania uses them for example in their line of engines, makes one run without any diesel "clatter" at idle too although the common rail system and injectors are an Alfa Romeo patent.

I´m counting on USA coming on strong in this area (too) when the companies wake up.
They have been asleep for about 30yrs and are into problems right now.

Look into Italian offshore boats for examples.
Cigala&Bertinettis Shaft 34´s has Trimaxes and diesels since the Early 80´s.
Italians have always been fond of surface drives and quiet offshore boats (=diesels) and you have to agree Shaft34´s f.e. do look good even thou they are a bit wider and offer more comfort inside the cabin.

We Assemble all the Porsche Boxters made and do Sisu special equipment trucks thats all.
But SISU don´t make their own engines they have used Valmet,Leyland,Rolls Royce,Cummins,Caterpillar and Mack engines.

Valmet and Wartsila are the only diesel engine makers.
The Wartsila Dyno"Room" is 800yrds from were I write this.
True is what you stated about automanufacturers but I was talking about independent shops and especially those building highperf/race motors as we aren´t talking about stock engines here.

Regarding Scania using different parts on their Big Rigs or Marine engines well it ain´t so, the longblocks are identical.
Scania first of all has a reputation to look after in the Truck business so the engines has to hold up there and take the beating they get in the wintertime and with 60ton loads.

The difference with the Marine engine is that it has twin turbos and is not as enviromentally clean as a Euro5 engine has to be in a Big Rig.
American trucks barely do pass the Euro3 test.
Also the Euro5 test dropped the V8´s power to 500hp from 580.

Regarding Yanmar modules they have surely been some tests with them but I don´t think anyone outside the modulemakers will get that info what you are after other than their guarantee and warranty it won´t harm the engine in a certain timespan.
Have to admit I haven´t looked into Yanmars that much, my interests lies in the Cummins,duramax marine conversions and then pure "racing" diesels like Seatek and Isotta Fraschini.

I think Gale do know how to take power out of a Gasoline engine too...he did the Buick Grand National prototype in 1981 among other things..

Heres a (US. Marine?) Marine Cummins...
http://marine.cummins.com/attachment...sb/FR92283.pdf

Must be a new motor, it appears to compete directly with yanmars 485hp, unless Im reading something wrong.

More info on that cummins motor please. Whats govt service ?
