Spec means spec. Dyno graph.
This graph shows the engines of the top three finishing cars at the SCCA Runoffs in the Spec Racer Ford class. (Note that the dyno is at over 5,000 feet ASL so numbers are low. Well, lower than low.)

Not as nice as the 0.5-1 hp difference in the srf group though.

What do you mean? There is a single engine builder and they examine the top 3 engines every year? Are they impounded at the track, right after the race? Who pays?

There is a single engine builder. SCCA Enterprises. Subsidiary of SCCA.
They regulate EVERYthing on the car with the exception of belts, data and a couple other non-issue items.
They build all the engines, seal them, and then they are sent out with the cars. They also do all the rebuilds and seal them. The variance on new motors out the door is 1.5hp top to bottom IIRC.
After the runoffs they take the engines out of the cars during post race impound. SCCA enterprises pays for it, not the competitor. The graphs have always been good and tight. They've done it for as long as I've been in the class.
SCCA enterprises also handles the sales (as the wholesaler) for almost all the parts on the car. That's where they make money. Nationwide they have 12 CSR (customer service reps) who maintain cars, sell the parts at retail and are at almost every SCCA race with the equivalent of entire spare car on their truck. Rarely does someone have to go home after a wreck on day one. I've only seen cars with serious frame damage go home (flipped car that wore down the roll bar) for not having the parts on hand to fix it.

SCCA Enterprises keeps the pricing relatively fair. It's a low tech motor and costs $3,500 for a rebuild. Serious racers always seem to have a spare motor around. The people who can't resist the urge to game the system allegedly collect air flow sensors on the theory that some behave better than others in different environments.

FYI prices just went up to 4000 for a rebuild and 5290 for a complete spare motor. I think I'm on weekend 40ish on this motor and it's not giving up power to anyones.
