It was a different time and place and the expectations were that if you crashed heavily you paid dearly for it. Today a track car is expected to provide sufficient protection that in most cases you won't get killed if you crash it. It isn't totally about weight, but a track car designed today...

I happened to be at the "Crash Masters" race at IRP, and it was just as much as a joke in real life as it was on TV... I was given free tickets, one of my buddies at work had a son who was racing in an electric car race for college teams so we went out there to give moral support for that...

That Jet Bug is really just a clown car.... Sorry guys, but it's all for show... The power numbers he is talking about don't translate into what we generally think of as acceleration. Jet engines make thrust. Unless you are moving really fast, they really don't make much power. Now if he was...

How about doing this one... About the right size and shape, and with a Allison Model 250 turbine it would be a hoot... OK, I'm kidding, but only a little bit, you probably wouldn't sell tha many, but it would be a pretty unique ride...

Nobody is going to build a replica of that.... That's the Ford "J" car that Ken Miles got killed in... It had big bunches of front end lift... Dangerous on the track..... Sorry, but even if it looks cool it isn't going to find a lot of customers...

Re: Rivet selection Do some research on the rivets that you are using. Specifically there are coated rivets that resist corrosion and are a much better choice for a street car. Most race cars were riveted together without any concern for corrosion. That's fine for cars that will seldom see...

What I think I am seeing there are holes that were placed at the ends of the cuts to essentially "stop drill" the end of each cut and allow him to form the bend with a flange. While that will work for a low stressed area, a "shrinker/stretcher" would be more appropriate if the stress is higher.

Do you know what MSD stands for? My Spark Died... Don't ask me how I know.... Depends on how much exhaust pipe heat is in the general area. MSD boxes work pretty well in most engine compartments, so they are probably good to about 200 degrees. Also, DON'T LET THEM GET WET.. Again, don't...

I agree that the control arm bushings on the C5/6 are most certainly a weak point (don't ask how I know, been there done that). On the upper control arms they shift so that the arm extrudes toward the front of the car and on the rear they allow the lower arm to go aft. Also agree that the T1...

Very nice job Fran,,,,just some ramblings... I have often wondered what a Corvette C5 suspension would look like in a mid engine car.... Now I know. It fits nicely, and the "long" trailing arms are gone.... Kinda suprised that they didn't use the entire rear aluminum "cradle", but that may...

;) DOH!!!!! my bad, forgot you were in De'twa..... OK, the big wheels can stay in the rendering.... Yes the reason that it creates more downforce is that it pulls more air out ahead of the tire and that air has to come from somewhere. The somewhere is under the nose and it lowers the...

VERY ATTRACTIVE!!!!! Neat treatment of the passenger area and windshield... Do wish that stylist would have drawn the wheels and wheel wells in "real scale" that is with fenders that have suspension travel allowance and fender clearance, and tires that aren't just a 1/4 inch of rubber on the...

I saw a 1968 MarkII for sale on 'Anamera where they quoted a fuel capacity of 140 liters. That would be 233 pounds of fuel at 6.3 pounds per gallon. So it is easy to see that much difference between a "wet" and dry weights....

Be careful with the comparisons relative to fuel load. Some of these cars could hold a lot of fuel so as to minimize pit stops in long races that weren't that hard on tires (like Daytona and LeMans). If you look on the Ferrarichat vintage forum the pictures showing the teardown of a P4 (0846)...

Fran, Right on, nothing is perfect, we all pays our nickel and takes our choice... Your SL-R is a great toy at a very fair price, and there are lots of other neat things out there too. I kind of lean more toward an RCR P4, myself, just because it is so drop dead good looking.... If I sat in...

Fran, IMHO, the 911 series is a triumph of extensive engineering overcoming what was essentially a really bad idea in the first place (hanging the engine out behind the rear axle). The combination of short wheelbase, and poor weight distribution makes driving one on the track more akin to...

The problem with mid-engine/transverse cars is that they often have an excessive rear weight bias. You can end up with 60+% of the weight on the rear axle and that isn't a good thing. Some designers try to mitigate that with a short wheelbase, trying to get more weight on the front wheels, but...

Frankly I'm so tired of "Cobras" and Cobra look alikes that I wouldn't build one on a bet. By my calculations there are far more "Cobra" replicas around than Shelby ever build of the originals... Purposeful, yes but beautiful, NOT... The Detroit Auto Show in 2005 they had the Shelby GR-1...

Fran, No doubt that the bars are required, being a long time Slow Car Club of America racer, believe me I FULLY UNDERSTAND how the Club is about rules, I was just musing that it is unfortunate that you have to have them there to play...

Seems to me that the relatively thick sponsons on the RCR would offer substantial protection from a side impact. Old sports racers had .042 to .063 sheet monocoque that wouuld have (and often did) folded up like paper in an accident, Fran's chassis is awfully robust, and if you did a decent set...
