Daytona Commitee Responds
Submitted by SuperUser on Monday, February 24, 2003 - 10:24am

RotaryNews contacted Grand-Am, and we were able to get their explanation for the rule changes, which basically disallowed the Rotary engine to run in any of it’s classes, at the 2003 Rolex-24 Daytona race. Mr. Pat Murphy, Special Projects Manager for Grand-Am, was kind of enough to grant us a phone interview to help clarify their rules. First and foremost, Mr. Murphy wanted to let us know, that Grand-Am has a very strong and professional relationship with Mazda and MazdaSpeed Motorsports. Mazda has been and is a sponsor and supporter of Grand-Am. MazdaSpeed Motorsports has even been in recent consultation with them, on future rules for the participation of Rotary engine powered cars, in Grand-Am endurance and cup racing. The following is the Grand-Am explanation “by class” has given to RN: Grand-Am Daytona Prototypes

There were no Rotary engine teams or cars, certified to run in this “new” semi-spec class. The class is based on spec approved chassis’, with current naturally aspirated production stock-block engines, producing in the 400-to-600-hp range. Grand-Am stated that no “current production” rotary engine would fit in this category. So, no Rotary engine here. SRP-II (Sports Racer 2)
This is a class were a Rotary engine car might have had a chance to run this year, but there was very mild interest from participants. Grand-Am stated that this class is going to be killed soon and the entry list was very low. A total of 5 cars ran, 4 of them being Nissan Lola’s, which by the way, have dominted this class for the last few years. There was one team that inquired about running a rotary powered racer, but nothing came of it. The lack of a Rotary powered entry to the class, prompted Grand-Am to disallow the Rotary engine, to save having to make equalization rules for a class that will be gone in the next few races anyway. GTS (Grand Touring S)
Grand-Am feels that there is no current Rotary engine car that can be competitive in this class. They claim that the disparity in horsepower would not allow the Mazda’s to be competitive. Both turbo and naturally aspirated cars are allowed here, with rules for tube frame and unibody cars. The approved competitors in this class: From the Grand-Am rule book: 1-2 GTS-approved Production Based (Unibody) Cars - Normally aspirated engines - maximum displacement 366 cubic inches. Approved *Turbocharged engines - maximum displacement listed below. 1-2.1 Corvette - Pratt & Miller C5-R 1-2.2 Dodge Viper GTS-R1-2.3 Marcos - Mantara LM600 EVO1-2.4 Mosler - MT900 R as listed Section 11-2.1-2.5 Porsche - 911 (993/996) *Twin Turbo 3.6L air-cooled only.1-2.6 Porsche - GT 1 *Twin Turbo 3.2L water-cooled.1-2.7 Saleen - S71-2.8 Porsche - GT3 Cup 1-3 GTS-approved Tube-Frame Cars 1998 to 2003 body styles 1-3.1 Chevrolet - Corvette, Camaro and Monte Carlo 1-3.2 Dodge - Viper 2001 1-3.3 Ford - Mustang 2000 and 2001 and Taurus1-3.4 Jaguar - XKR-8 20011-3.5 Oldsmobile – Aurora1-3.6 Panoz - Esperante 20011-3.7 Pontiac - Firebird and Grand Prix RotaryNews feels that a 2000 or newer, well-prepared and funded race FD RX-7, with the correct amount of boost and engineering behind it, might actually show decently in this endurance class. Especially, if allowed to run with good equalization rules. We can dream, can’t we? GT (Grand Touring) This class is for 1998 or newer, “naturally aspirated”, unibody production vehicles. Since there hasn’t been a naturally aspirated Rotary powered vehicle available since 1992, it automatically excluded Rotary engine powered cars from this class. Grand-Am will be discussing equalization rules and exemptions with Mazda, for the RENESIS powered RX-8 next year. Let’s hope they can work out a good compromise. The approved competitors in this class: From the Grand-Am rule book: 1-1.1 Acura – NSX1-1.2 BMW - E46 or E361-1.3 Corvette - C51-1.4 Ferrari - F 360 Modena1-1.5 Lincoln - LS RS8R1-1.6 Marcos - Mantis 1-1.7 Porsche - GT3 R and GT3 RS1-1.8 Porsche - GT3 Cup To sum it all up, it looks like bad classing circumstances and timing conspired to leave us without a Rotary racer at this year’s Daytona-24 hour. Mr. Murphy wanted all Rotary enthusiast to know that, Grand-Am did not have any sinister plans against Rotary engine powered cars or racers. The rules just happen to work out this way. We hope to be talking with a few of the Rotary engined, potential and previous, competitors to get their take on this situation. Stay tuned for some more follow-ups, on this most important story.

"the rules just happened to work this way" that is the most synical response I've ever heard. I would like somebody, Mazda corporation among others(racers, competitors, aftermarket mazda parts builders/developers, any wealthy fans{if I got the money, I would take on a law suit} to follow a suit, not for the money[although a lot of money is been lost in preparations, expenses, crews, parts, logistics, advertisement, etc]...but for the principal, clear /straightforward dishonesty with the clear intent of discouraging the rotaries from competing . Rules cannot happen to work in a way that will discriminate against one competitor well at the same time allow and induce participation of the other members. There is no excuse, this is unforgivable.

Basically theyre saying that It probably wouldnt have made a difference for this year so it doesnt matter if they ban rotaries forever...

If it doesnt make a difference, why ban it??

"bad classing circumstances"?

I can see Grand-Am saying this if this was the early seventies and they have not heard or seen a rotary before BUT, this is not the seventies. The Rotary has been out for over thirty years. It has produced a 24 hour winner.

When the question is asked... who believes Grand-Am's explaination raise your hand. I will not be raising my hand.

Personally, I think they're full of it. It's easy to build classes around the rotary's weaknesses, then claim that uncompetetiveness is a reason not to allow the rotaries because they probably "don't stand a chance"... I can't buy it.. Has anyone heard Mazda's take on this? I think it would make for another good article on rotary news ;)

So basically, they were too lazy to write some regulations out for the rotary? What a load of BS!

Or then ASSumed that the rotary couldn't compete? Well if the rotary can't keep up then why don't you remove some of the restrictions on it???? maybe it would be able to keep up then.

I also want to hear Mazda's response to this.
