Mike,
What happened is that during the ARRC a rumor started that the SCCA was again considering SIR's for the class. Period. That's it. None of us want that to happen, so many of us are looking at ways that we can keep the class from zooming out of control (before it really gets started) and forcing somebody to make changes that none of us likes.
The performance of these cars at Atlanta was spectacular. I've heard from people that the "hired guns" out there were running corner speeds 10mph faster than some of the ultra-quick DSR guys!!! The lap times overall are already there, and some of these cars were essentially NEW.
As Sean pointed out....Many of us have been involved with the DSR class and we've seen what happens when there is money and fairly open rules in a class. I've documented the trends in DSR on another forum, but suffice it say that from 2004 to 2007 DSR has went from one of the most subscribed classes (using Runoffs entries) to one of the lowest. Costs for a turn-key new car in that class have went from under $50K in 2004....to around $85,000 today. The engines in some of those cars...and the parts needed to install one....are over $15,000.
Russ also makes a great point....All of us were so excited to be a part of this new class and to get our cars out running.....I just don't think we really thought about the engine "arms race" that goes on unabated every year between the bike makers. Now....we should....because like Sean says....it is inevitable that money flowing into this class will dictate the newest, latest, greatest engine for those that want to be at the pointy end of the grid.
Also....per Sean's request for Info...Stohr sells an "Engine Install Kit" for around $4,300. Ours is a bit less....but not much. That includes everything you need to install the motor in the car and get it running. I don't think it includes an airbox.
