Cummins Indy Car!

Don't know if this has been posted before, but looking at the Cummins entry on Wikipedia I found this old Indy car with an early Cummins in it:

They raced it and it did very well if I remember correctly. I think it won the Pole but lost the race due to a clogged up air intake. They stopped racing it because Indy banned turbochargers for a long period after that.

Here is a picture I got from somewhere a while back:

Good 4 page article:

http://www.caranddriver.com/features...lted-indy.html

At the same time that Agabashian shocked the racing world by winning the 1952 pole, several Chrysler and Dodge stock-block, 331-cubic-inch engines were being tested. All were recording speeds as fast or faster than the 270 Offys used by the so-called establishment team owners. Fearing their engines would be made obsolete by either the diesel or the Detroit V-8s, the Offy owners brought pressure on the AAA Contest Board to pass rules reducing displacement of the upstarts to a level where they could no longer compete.

I have that same Cummins logo on my hat (the red ball Cummins logo).

Looking close at the engine, it appears to have 2 injectors per cylinder.

I was noticing that myself. I wonder if they hadn't figured out how to get injectors to flow enough for a high performance engine or something.

That appears to be similar to the old three head cummins fuel system like we use here for back up fire pump.. One of the lines is a return line to the fuel manifold.

I actually have the magazine with the article. It is really cool to let other people know that a diesel can do so well. Was it LeMans this past year or so that they had a diesel win? Not sure if that is the correct race or not.

If I recall correctly, one of the advantages of that car was no fuel stops during the race.

LGP,that was one of Cummins later efforts.The earliest was I believe around 1931.In the late 30's there were two cars entered,a two stroke and a four stroke.The four stroke went out with transmission failure.The two stroke finished the race in last place.
