Ken I'm not sure the point you're trying to make but it appears that you're comparing NASCAR to ICSCC Conf. Production. It seems like your illustrating the benefits of change.
Here I go!
NASCAR: needs money... Through increase in popularity of viewership, the series prospers. The changes, even though current cars don't resemble modern street cars, has allowed NASCAR to achieve it's primary goal. Growth and profit. Also, the cars represented in NASCAR in their stock form would have CAUSED the series to die. Has anybody seen the modern Impala or is excited to see a 2011 Toyota Camry Hybrid go racing?... I'm not. The cars produced by the manufacturers have changed in a way that is not concurrent to the goals of NASCAR thus having a tubeframe spec car has allowed the series to transition into something that has become the 2nd most popular sport in America behind the NFL with over 75 million US viewers and another 75million viewers world wide. That's called, winning.
ICSCC Production: needs money... However, there is no corporate sponsorship, no TV time, no viewership. The money only, ONLY exists from entries. Unlike NASCAR, OEMS are still making production cars that are congruent to a Prod class and the OEM's on many of their cars have evolved BEYOND the rules of the Production class which are 55 years old. An aftermarket header ISN'T rules-creep... it's
reality creep. The reality is that it's not cost productive in a racing sense to be protecting rules that only serve those who want to race cars from the 1960's. Or, perhaps we should just change the name of Production to "Vintage" since the rules don't apply to your modern automotive enthusiast.
In 2001 a little movie came out that radically, RADICALLY changed the enthusiast market. That would be Fast and the Furious. Since 2001 the "tuner" market has become a multi-billion dollar empire and tuners are everywhere. Now tuners are just your modern day entry-level enthusiast. As some point these tuners, will autocross, drag race, run track days and eventually do schools and then racing. The last 2 times I instructed this year I saw cars with turbos, swaps, headers, mods, and I even saw a 1986 Toyota Corolla (AE86) with an S2000 F20C engine swap in it. The future of Conference, is the 16-22 year old who's putting Headers on his daily driver right now, not the 65 year old man restoring a 1972 Datsun in his farmhouse.
Has anyone in Conference EVER been to a NOPI or HIN show? ANYONE? Do you even know what it is? We should realize that those kids will eventually be (need to be) our feeder demographic, not their grandparents. This also is a much bigger argument for how we market our Conference as well but that's for another thread.
I meet an "enthusiast" every couple of weeks that asks me about how to get into racing. Why? Because I'm young, I know how to use social media, I'm on the enthusiast forum boards and I'm constantly advocating to these tuners to get out to a track day, a school, an autocross, and they are. I've been witness to massive attrition over the short time I've been racing (2004). People leaving because of cost, lack of competition and "other". Thus my advice to maximize a newcomers addiction without it destroying his/her life is this:
"Come out to the events, volunteer, or just watch the races. Look at what groups have large fields, competitive classes and then go talk to the drivers about what they spend to do this. Some classes might look affordable but the drivers are spending 40k to do it while other racers are enjoy loads of competition by spending 1/4th of that."
Do you think any newcomer is going to look at someone racing by themselves in EP or FP and think... "oh wow, I want to go do that!" I don't think so.
While the "rules-creep" argument hits home with a few members, remember that adaptation is the only way anything survives over time.
And let me take a moment to post a picture to prove my point as well Ken.
Here's the future of Conference Production:
And more fun with Pictures... Here's an OEM S2000 manifold and an OEM Type R manifold
Sure looks like headers to me!
