rlogan Posted May 4, 2007 Author Posted May 4, 2007 You just can't win....yeah, but I say we do it per liter....I'm only 0.7 over...I bet a V8 in a miata is a lot more than that Quote

davidfarmer Posted May 6, 2007 Posted May 6, 2007 I pretty much agree with everything everyone has said....good discussion. I continue to feel that tube-frame cars have some sort of adjustment in ST, or we'll end up with ex Trans-Am/GT1 cars. I don't think the aero penalty makes sense though. Maybe an across the board Tube-frame adjustment, or even one that gets steeper as the car gets lighter. I just don't know. I didn't realize the numbers were public. I'd love to see some when MA and SE get around to getting them all together. Heck, I haven't even turned mine in yet, as mechanical gremlins kept me busy my one race weekend. Quote
National Staff Greg G. Posted May 7, 2007 National Staff Posted May 7, 2007 David, The problem with any type of single adjustment factor for "tube frame" is that there is a huge difference between a NASCAR/GT1, etc. "tube-frame", and a FF Cobra "tube-frame". For the tube-frame cars that are essentially "production tube-frame" vehicles like FFC's, Caterhams, Lotus 7's, etc, we can come up with adjustment factors much more easily since they are all built to their certain specs. Whereas, GT tube-frame cars, etc. are not. Quote
claykos Posted May 9, 2007 Posted May 9, 2007 Exactly.... I would venture to guess that the factory unibody/frame on a modern Corvette, Porsche, whatever is MUCH stiffer than the FFR "tube frame." Quote
wallyman424 Posted May 9, 2007 Posted May 9, 2007 Exactly.... I would venture to guess that the factory unibody/frame on a modern Corvette, Porsche, whatever is MUCH stiffer than the FFR "tube frame." stiffer, but waaaaaaay freakin heavier. Quote
rlogan Posted May 9, 2007 Author Posted May 9, 2007 Wah, wah.... Heavy schmevy..or uhm chebby! That's what the HP/weight and weight penalty are there for.... Quote
davidfarmer Posted May 15, 2007 Posted May 15, 2007 In general I would disagree. Yes, the Vette has a great chassis....most production cars do not. Most tube-frame cars has stiff chassis....I have no idea if the FFR does. As far as I'm concerned, you can dump the aero penalty. If the cars prove to be faster due to their narrow size, or other unknown attribute, then an "adjustment" can be made at that time. After analyzing the "weight" adjustments, I think lighter cars still have a potential advantage IF they can get out in front to begin with. However, as we all know, PASSING a more powerfull car can be very difficult. I think it will take a season or two to work this all out. Quote
