HA! Why??? I never thought of it as that significant of a job that I needed to write a technical essay about it.

As I'm sure you are painfully aware, usac has absolutely zero interest in the "knowledge and opinions" of others..... Besides, I get paid purty good money for my "knowledge and opinions."

Hey, Jim. The following is some misc. technical articles I posted, probably, two years before usac invented their new car...... one is a post I wrote as their new secret car was being built. You might be interested.

The intent of my proposal is not to replace the current formula at Indy.
My proposal is intended as a plan to give USAC and USAC trained drivers a top level pro quality series of their own so that the USAC drivers would not have to leave USAC to move to the next higher level of their careers.
There are many new quality 1.5 mile tracks available to these guys if they had suitable cars.
My proposed cars should be able to operate comfortably in the 175 to 185 MPH range. This is something the current cars can not do, as indicated by testing at Nashville, so they are seriously restricting their future opportunities and potential growth........
if USAC is even interested in growth.
Right now, with the impending management change at USAC, would be a good time to decide what they want to do with their future.

I think we need a front engine Indy caliber division more than we need rear engine sprint cars.
My thinking is this........... All of the little league hobby stock racers can dream of moving up as far as Winston Cup and there is a system in place for them to methodically do that. All of the little league formula ford racers can dream of moving up to IRL, CART, or even, F1 because there is a logical system in place for them to pursue those goals......... Unfortunately, when the young midget and sprint car racers reach the Silver Crown level, as the division currently exists, they are forced to take a totally different career path if they want to move to the next higher level.
The solution, as I see it, would be to develope the current Silver Crown pavement type cars technically and statuswise into a championship caliber division with cars suitable for running at speeds of 180 to 190 mph on the available tracks from .75 mile to 1.5 mile in length. there are a lot of new 1.5 mile tracks out there that these guys could be using if they had a more suitable chassis. This would require some shape, structural and mechanical upgrades to the cars but it would allow the drivers to use and develope their current skills at a higher level.
Although it would allow the drivers a next progressive step to their current careers, it would not necessarily solve the cost problem because a car could be designed to cost as much as a current Indy car, i.e. the Panoz f.e. sports car....
The key here would be the rules of the new formula. If serious cost reduction is to be realized, you could not consider using the 100 plus G IRL type engines, the 40 G X-trac type rear mounted gearbox or the multi jillion dollar computer and wind tunnel developed aero package.
I think a reasonably priced car could be designed using the offset roadster type layout and many available, reasonably priced pieces and systems.
Structurally, the chassis could be built using a basic light tubular space frame and bulkheads with molded carbon fiber stress panels attached for increased stiffness and energy absorbing crash protection. This type of construction has been used successfully by Riley and Scott on most of their WSC sports cars.
Mechanically, I would use the basic alum V8 pushrod racing engine of about 305 c.i.( to control speed and fuel milage), a nascar style Jericho transmission, and a current style, quick change rear axle center section..... I would use an independent suspension layout front and rear because I think that the improved handling and stability, as well as the known crash energy absorbing characteristics, would be a great improvement on the big 1.5 mile tracks. Another good thing would be that the driveshaft could remain stationary through the driver cockpit area.
I would get rid of the ridiculous 18 inch wide rear wheels and specify the current Indy spec 14 inch rear and 10 inch front wheel sizes. A much better quality tire than what is currently available for USAC sprint and silver crown, would be needed.......... Gee, I wonder what the Indy style radial tires would do on our new big track SC car?
Aerodynamically, obviously, the priority would be streamlining plus special attention to getting cool air to the radiator and engine air intake. I would prefer no wings at all, but a basic front and rear wing package could be specified for chassis tuning purposes.... NO UNDERWING TUNNELS!!!!!!....................on second thought , SCREW THE WINGS,
I HATE WINGS, SO NO WINGS!!!!!!!!!!!!!
Bodywork would have to be upgraded from the flimsy junk that is currently used. If you look at any picture of SC cars on a mille track, the front noses are all deformed by air pressure and in car camera pix show that the engine hoods are on the verge of flying off at all times, Not Good!
Race distances could be limited to the current hundred mile length or could be increased to 200 or, even, 300 miles.
Hundred milers would cut costs if these new cars could be made to run 100 miles, nonstop, as they do now. There would be no need for the expense of high speed refueling equipment or the crew to operate it . You would, probably, change tires during your refueling stop so your tire bill would go up considerably with pit stops. Also safety would be improved without high speed pit stops. ....... A solution to running a 200 or 300 mile event would be to run them as twin 100s or triple 100s.
FUEL... Well, the biggest problem with a front engine layout is packaging a large volume and weight of fuel. I would try to come up with the amount of fuel required to run 100 miles, nonstop, and split the amount equally in cells on both sides of the main chassis structure to minimize handling changes as the fuel load burns off. ... maybe easier said than done, haha!!
Oh! one other rule that I forgot to tell you about is the "ten feet of wire rule"..... you are only allowed to use ten feet of wire on the whole car..... That should do away with the mega dollar engine control and data collecting computers. I might suggest that you use your ten feet of wire for spark plug leads instead.....hahaha!
USAC could sanction this new “Super Silver Crown” division and eliminate the old SC dirt track races which are a total dead end street..... In fact, USAC should get the sprint cars and midgets off of the dirt tracks also if they ever intend to improve their image.
The next step up from these cars, technically and moneywise, would be to use this type of chassis with the full IRL type engine and rear mounted X-trac style gearbox and run some 500 K races with full pit stops ......... now wouldn’t that be some great racing!!!!!
As can be seen in cart, IRL , F1 and, even, current SC, long standing rules formulas can become quite stagnant and with the use of computer design, the ultimate solution to the rules can be quickly determined, resulting in virtually all cars being identical except for their paint jobs... Changing or tweaking the formula once in a while can be good for adding a little variety and renew technical interest.

I am interested to see what this new SC car will look like. I am familiar with Riley & Scott, who USAC has contracted to work on this project, and I am familiar with the way they think. I believe that they are, mainly, working on crash protection. I fiqure that they will replace the nerf bars with some sort of foam or honeycomb filled carbon or alum "crash decelerator" box structures. The rear bumber/push bar will be replaced with form fitted carbon or alum, foam or honeycomb filled , "crash decelerator" structure, surrounding the fuel tank. A foam or honeycomb filled nose fairing will also be used for forward crash protection. I reckon the first prototype of this new car will look something like a cross between a "bumper car" that you see at the county fair and one of those "Legend Roadsters" that the oldtimers raced in Texas.
