I have a question on the motor rules and please correct me if I am wrong. POWRI and USAC both allow 161 Esslinger motors and 174 Fontana motors. USAC still has a RPM limit on both motors but POWRI does not have no limit. Why wasn't chevy Gaerta's allow to go to a 174 cu. in. motor to compete with these newer motors???

I was under the impression that the 174 rule was for any pushrod, 2 valve per cylinder engine, not just the Fontana..... but don't take that to mean I know this for sure, that's just the impression i was under.

Fontana is a "non cross-flow" head, whereas the Gaerte is cross-flow; aluminum block and head, pushrod, non cross-flow, 174 C.I. Cross-flow, 166.
There's way more, but that's the rules that pertain to these to motors.

I've worked on these cars for a long time. And still haven't found a motor on one!

I think Casey Shuman drove an electric motored powered midget down in Florida a few years ago. I hear that now however they are working on a wind turbine powered car to meet the the new and much stricter EPA guideline and laws of the future. That is if OSHA doesn't outlaw racing all together. Think how healthy you are going to be when you start peddling that bike all over. You won't even have to worry about your health care provisions anymore.

If these darned motors rules weren't so darned specific>> pretty soon the good motors would prevail and the "Boat Anchors" would be rendered into new and more useful machines. This old world ain't designed to be equal. Why do people always want to try to make it so?? Why do we hold good motors back to make poor motors competitive. (Sorry Racer)

So, I guess my car is enginecycle powered...
mo·tor
/ˈmōtər/
noun
noun: motor; plural noun: motors

1.
a machine, especially one powered by electricity or internal combustion, that supplies motive power for a vehicle or for some other device with moving parts

Technically speaking an engine is different than a motor. An engine is a device that burns or consumes an energy source. Whereas a motor does not change the chemical makeup of its energy source. You must have an engine to produce the energy that powers a motor. In most cases.

I guess the online dictionary I got that definition from is mistaken, technically; think of all of the terminology and business names that are going to have to change because of this revelation; Enginesports as a whole, Engine Trend and Engineweek magazines, the IMCA will have to change to the IECA, the first stanza of "Born to Be Wild", out the window...

Not only do we have to hold back the good motors to allow the poorly designed motors to race but we also have to be politically correct when using the term to describe them???
