Interesting tech read -- nitro rings and bearings

[flapjack]

I thought this was an interesting read for those who care
about the techie aspects of nitro cars:

TOP FUEL RINGS & BEARINGS Precision Engine

I had no idea that pressure at combustion is 16K psi.

They even reference the phrase "mass will save your ass".

Wow,
I could dispute most of the ring article.

I can honestly say that top teams are not replacing rings every pass. We have developed rings that live for several passes. The statement about materials that rings are made out of is many years old. Stainless based materials with CrN on the face is very common in Fuel today.

Just some insight.
Thanks
Matt

The article begins by discussing a 4.50 @330 MPH pass, so I think it's safe to say it 's based on information that was valid prior to 1,000' racing. (The date says May 22, 2009) Still, extremely interesting. Thanks for the link.

Yea, I see the date now. That explains why it is "out of date" lol
Fuel Engines are animals for sure.
