That would be GPM, not MPG.

Actually it doesn't use gasoline.  The class has different fuel sources.  The Supercharged and turbocharged cars use methanol while only the nitrous cars use racing gasoline.  Indications are that this might be a supercharged car.  :whistle:

I decided I’m too old for anything with too much power. My son had me drive his car to the grocery store and I had him drive it on the way back home. I would have loved it when I was twenty, or thirty, or forty. For what it’s worth I was driving unfamiliar roads in Louisiana and a lot of crazy traffic.

Sad but almost true.  Some of my former cars would probably stop my heart today.

There's a reason why 4 of my motorcycles are for racing  (track use only) and my street bike is a 43 year old Harley.

For the techs, this type car uses a screw type supercharger.

Image result for roots type supercharger

The Roots type is what was used as a scavenging blower on two stroke Detroit Diesels. The blower from the 6-71 Detroit became a popular choice on the drag circuit.

One of the downsides for the diesel application was that if the oil seal let go on the drive unit, the engine would feed on it's own oil, and run away un-governed until it self destructed. 

That's why there was an emergency shut down to close off the air intake in case of such an event.

Blowers and nitrous do not play well together.
