Dan... That was not the original intent of the request for "expressions of interest".... It was more along the line of the concept that for forty years (I am pretty sure it was 1971), there has been diesel classes - starting with diesel streamliner back then..... We were looking at this from the point of view that the other special construction category should merit having the same fuel sub-categories as the "first" one....
And diesel engines, by virtue of their somewhat unique (if such I can really say) combustion principle, have ALWAYS been supercharged/turbocharged WITHOUT CLASS PENALTY since the initial inception. It would be my assumption that a supercharged diesel running in any of the gas or fuel classes will HAVE to run in a BLOWN class.... Would I be correct in assuming that, Dan? The diesel engine is just NOT going to make the same horsepower as a comparable gasoline fueled superchargered engine will make. I will use the GM "ECOTECH" engine as an example (and I could go back to the early 80s when Don DeBring had a 2 liter Ford in his Longshot streamliner....) .... Ron Main's car in the "ECO-FIRE" incarnation went ... what... over 300 mph! The Chassis Engineering Special is only into the low 300s .... and the JCB Streamliner was about 330 mph.... If the JCB 'liner was powered by two equivalent sized turbocharged gasoline fueled engines, the car would be a 400+ MPH car!
So, for all of you who say that running diesel in a gas of fuel class is how it should be.... well.... unless someone is content with going home with nothing more than the expectation of receiving nothing more than a brass timing plaque for their efforts, diesel power will be relegated to "also ran" status in anything but a diesel fueled class.
So, if "open wheeled special construction" classes do not get diesel as a fuel, well, our point of view will be "SO BE IT" and we will work with what we CAN do.... what, exactly, I don't know yet but.... something...
