Couple of thoughts:
1. I have been reading the new Folmer book entitled George Folmer American Wheel Man. For everyone that wants to go back to the days of the Can Am and the other series in the late 60's and early 70's, just remind yourself of all of the great drivers that were lost "back in the day" top speed has been governed for quite sometime now...lap times have gotten quicker as a function of suspension, brake and aero advances...We are living in some sort of fantasy land to think those guys self governed themselves...they did not....what they did was die trying to go as fast as they could
2. As for the Can Am...one of the reasons it was so wild was because "New" technology showed up at just about every race...from the Shadow knee high car to the Sucker car to the 917-10 and 30 that shut things down
3. RE: Sound. I loved the sound of the old engines....in Montreal, you could hear that siren scream all the way across the St. Lawrence, and as hard as it may be to believe, when you are standing right beside the fence...which you can do heading into the hairpin at Montreal, the sound the car makes as it cuts through the wind is almost as piercing as the engine note....New isn't always bad...the first time I heard the Audi turbo diesel at Sebring, it sounded like a sewing machine going by....but what was lost by the engine note was suplanted by the sound of each tire grabbing for grip during heavy braking or exceleration....plus, you could actually hear the suspension pieces working as the car tried to dampen everything that old track threw at it
4. Time marches on. alternative fuel racing cars are the future...love it or loath it. I for one am glad that racing has the possibility of getting back near the front of the curve from a technology standpoint..(It may be as Curt points out, they are taking something simple and making it complicated, but at least it is some progress).....I think all of you guys who yearn for the past have nothing to worry about....NASCAR runs just about every form of motorsports in the US now...so get your fill of those lovely DP cars....ain't the past just wonderful
