Built for NASA road racing series: American Iron. There are horsepower/torque limits based on the weight of the car. We should actually make less than this, and have to ballast up the car. However, the 2012 rules give us a hp/tq increase, so we should be able to remove the some of the ballast.

Why does the dyno chart look like a camel?

And a double humper at that!

Because the fuel injectors don't know what to do with only 10 psi.

The double hump is the AFR curve. It looks drastic due to the scaling.
