Winner Of The Race Engine Challenge

Find that kinda weird, that they would allow valve rotation in an "inline" class?!?

They only had 2 classes. Splayed, and Inline. Since the C3 is not splayed, and all the valves are parallel, it went in the inline class.
Pretty sure that's how they got it in NASCAR in the 90's.

sorry but I think all these competitions are exclusivly for the wealthy well equipped outfits, and bragging rights. For us ones at the bottom of the food chain we would never have a chance, and not because lack of ability but lack of $. Sorry again.

That's completely wrong. I was there for 3 days of the competition, and these competitors represent the average engine builders, that make up the majority of this business. These guys all had budgets to work with. I would say that the most expensive engine there, is the one that won, and Randy almost beat it with a 1992 SB Ford.

This competition was not filled with the wealthy and most well equipped, but with some of the most passionate and hard working engine builders. That, many times, can overcome, or at least give the wealthy and well equipped a good run for their money. I was very impressed with the zeal and character of the participants at the Race Engine Challenge. My hat is off to all who participated .

a fairer contest would be to use modified stock cylinder heads to show the potential of the engine as produced.

[Stan Weiss]

They measured the compression ratio to be a tenth to high on one side so, I got tossed.
Not near responsible for the 70 some points difference between the two engines.

It sure would be nice to have a "seasoned" tech inspector there for each operation in order to get the correct calculations because I really think it got messed-up.
Oh, well.

How did they check it? Did they go by published data on some components? Or was everything actually checked?

A cc amount of near 2.5cc's got taken into consideration twice because the piston was .012" above the deck at TDC ... when that amount should have been removed from the swept volume only once.
.100" down from TDC is only .088" down from the DECK so the down-fill divider in the formula was bad data.

It's over ... it is what it is. I will improve it and be back next year with a vengeance.

Can someone post the formula for calculating the CR that was used. For how I do it (CR) the down volume from deck is only used to come up with if the volume is greater or less that a cylinder (Bore) of that height "X" that down volume. So what height is used does not matter as long as the dome if there is one is covered.

Why?
This class is supposed to represent a "top of the line", street/strip engine, that an engine builder would build for a customer.

I'm not so sure about that. I saw some pretty pricey parts on some of the engines there. A lot of our stuff was used.

Nothing you wouldn't see on a good street/strip engine.

Exactly.

[pamotorman]

did they use the dead space area between the top of the deck and the top ring in the calculations since the piston went above the block.

I guess i have missed something along the way. I thought Randy finished second in the canted/hemi class but this thread is talking about inline. Did he have an entry in each class ? If so what engine type did he enter ?
Congrats on the effort Randy !

The C3 Ford "Yates" head has the valves STRAIGHT with NO cant at all but twisted,
similar to a 409 Chevy with a combustion chamber.

Thank you for the explanation Randy.

[Steve.k]

Walter you won that deal no doubt about it. Im glad you are a gentleman and accept the ruling! Rules are rules. We all know the .1 in comp if it was there had little or no bearing on the point spread. Its a tecnacality thats all. This happens all the time in motorsports and we learn to adapt. We know you'll be back next year ready to go. Its all good!!

[blykins]

Sorry for the raw deal, Randy.

Very nice piece you built.

[WeingartnerRacing]

I’m sorry Walter didn’t win. There were rules every one has to follow them period. When one team gets even the slightest advantage and they let it slide then the competition validity goes out the window. (Trust me)

I’ve got nothing against Randy and I respect him doing the right thing. It just is what it is.

I competed in emc it is not cheap, nether is racing, and it is hard for low buck teams to compete but not impossible, Ask joe carrol. Also there are well financed teams that left disappointed. So money may not be the end all but it makes it easier.

YEP ... happens all the time.
