Allis Chalmers HD7 with Detroit diesel 371 no muffler

I wanted to see what it sounded like, it didn't sound great. Better with muffler.

I wish it was my property. This is at the Antique Gas and Steam engine museum in Vista, Ca North of San Diego. I am a member, so we get the pleasure of getting these old tractors running again.

I believe all 2-stroke Detroits have a supercharger of some sort, some have a turbo in addition. I don't think the blower is boosting much over 1 bar.

@mpwelk correct the blower wasnt as much about adding power as it was allowing it to function... these things need a scavenging effect to run... thats what the blower did

[AMCtilldeath]

@toddly2009 correct they will not

[toddly2009]

@AMCtilldeath i dont think they will run without a blower will they?

[JtsGreene]

@mpwelk Nope it isn't, they breathe into the cylinders at just over atmospheric pressure. Turbo does some to help but you can only put some much air behind a blower that can't handle more than it's made for.
