Cobra4B Posted August 3, 2012 Share Posted August 3, 2012 Curious the rationale behind this rule? The Mercedes SLR street car has fender exit side exhaust. Rebuilding the Panoz right now and having the exhaust exit behind the front wheel would cut down on a whole bunch of exhaust piping and reduce cabin heat. ~Brian Quote Link to comment Share on other sites More sharing options...

Cobra4B Posted August 3, 2012 Author Share Posted August 3, 2012 Can God give me a waiver? I want a 2400lb Panoz Quote Link to comment Share on other sites More sharing options...
getfast Posted August 6, 2012 Share Posted August 6, 2012 Unofficial educated guess is that it has to do with fumes and/or other things that can exit through exhaust pipes (smoke, fire.) ps- the Mercedes in question is not technically state-inspectable in Virginia for that reason. Although the only one I've ever seen at a dealership got a sticker on it anyway Quote Link to comment Share on other sites More sharing options...
Cobra4B Posted August 6, 2012 Author Share Posted August 6, 2012 Greenbaum said it's a "safety rule" and there was no chance of getting a waiver. Quote Link to comment Share on other sites More sharing options...
Grintch Posted August 9, 2012 Share Posted August 9, 2012 Unofficial educated guess is that it has to do with fumes and/or other things that can exit through exhaust pipes (smoke, fire.) Right, carbon monoxide. Exit the exhaust in front of the driver, and you will be breathing it. Which in the right concentrations will make you light headed or pass out. Not a good thing to do at 100 mph. The SLR doesn't normally run around with its window down, and I bet its aero was extensively tested and tweaked to keep the exhaust flow out of the cockpit.

This may be a good time to revisit the rule, how about exits behind the driver or out the side? how about this Quote Link to comment Share on other sites More sharing options...

One of the few things I can say I have experienced on track that has also been experienced by a certain pro racer named Tom Long is... carbon monoxide poisoning. Granted he's in way better shape and his happened in a $300k+ Mazda RX-8 during a 24hrs of Daytona while mine happened in a $500 Volkswagen during a crapcan race, but the experience and effects were very similar. I'm not someone who pits in early. And I pitted in early, before passing out. It made me as ill as I have ever felt in my adult life, and I still wasn't right the next day. I wouldn't wish that on anyone. Which may be part of why we have this exhaust rule? Thinking out loud, Jon Quote Link to comment Share on other sites More sharing options...

Happened to me last June in the Thunder race at Rd Atl and I spent some time in the infield care center after the race. It took a couple of days before it was completely out of my system.
