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.)

Too bad the FSCCA cars weren't so close. Still pretty amazing across all those cars though.

Meh...

In PCA production class that would look like one line right on top of each other.

all are within 5hp......more like 1 until the very top end

% wise the fe cars weren't as different as the graphs appear. Also the motor that was low. It was all of 2-3 down and easily could have been the motor out of th three that I believe was over 30 weekends old.

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

Splash of "good" Gulf.

Did they dyno the cars after the race? Is this SOP after every race?

Circuit Motorsports

Sop is for the runoffs top three to get their engine pulled and it goes back to enterprises, the builder, to see how they stack up. Enterprises pays for it.

Circuit Motorsports

Fwiw. Redline is 6000. Most shift at 53-55. Bog limit for most is about 4000

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?

Circuit Motorsports

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.

Circuit Motorsports

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.

Weekend 40ish!!!!! That sure is affordable!
