Re: Autoextremist: NASCAR May Return to Production Bodies and Engines
Toyota's got a rear-wheel-driver, it's just badged as a Lexus.
Maybe we'll see the FT-86 in NASCAR if it makes it to production.

Re: Autoextremist: NASCAR May Return to Production Bodies and Engines
never happen..
the car might look like the stocker but thats it..
putting a unit body style on a highbanked oval.. would be a deathwish... even with a roll bar..
66% of the reason for the cot was fan safety.. after parts killed and mamed a few at races. with the old car that had the stocker roof/hood/deck lid

Gee, who knew that all of those Mustang FR500Cs (http://www.fordracingparts.com/mustang/herocard1.asp) and Porsche 911s (more correctly, the 997 GT3 RS model, as configured for Grand-Am GT competition) hitting the highbanks at Daytona International Speedway last weekend were such "deathwishes?"
Of course DeLorenzo's hardly alone in condemnation of the awful COT. See e.g. http://www.bangshift.com/blog/Speedy...er-s-Goat.html

Boy I wish folks would become more informed before they start typing out nonsense.
But opinions are like assholes, everyone has one.
Unibody racecars are used all over the world and can be made as safe and stiff as needed. They are, however, frequently more expensive to build than tube framed silhouette racecars. They are also much more difficult to repair.

Re: Autoextremist: NASCAR May Return to Production Bodies and Engines
For the purposes of argument, let's assume your conclusion is correct.
Then don't run'em at 200.
NASCAR racing would be just as good, if not better, if NASCAR used production bodies and CURRENT production engines with a Five Liter displacement limit (and I'm not just saying that because Ford's Coyote 5.0 would probably destroy Chevrolet . . . because GM would quickly have a NASCAR-ized DOHC five liter homologated or obtain a "equalization rule" such as in Daytona Prototype competition).
From an engineering standpoint, unitized and monocoque construction has proven itself in competition around the world. A separate tube frame is not necessary for either strength or "safety." In fact, the old Holman-Moody Fairlanes -- which helped start the deviations from "stock" -- were only 3/4 chassis cars. Chrysler's NASCARs in the 1960s and 1970s were unitized, with strategic tubing reinforcements. It wasn't until downsizing in 1981 that the separate frame/Galaxie front suspension/Galaxie floor pan/Chevy truck arm rear suspension specifications became required. Everything afterward until the COT (e.g. front steer, fabricated body sides) was a modifcation of the 1981 "box."
As long as the driver's compartment is adequately rigid (which can be accomplished with a proper cage, and body parts are properly affixed/tethered, there's simply no technical reason why a unibody cannot be run on any race track in America (other than hidebound sanctioning bodies preventing it).

Are you agreeing with me, or what...

With the factory body styles, expect those "factory-based" engines to be limited to 500 hp to reduce areo problems at high speeds.The official Bangshift garage door guru. Just about anything can be built using garage door parts, trust me.

But the cost argument is both unproven and unwarranted. In the superteam era, NASCAR racing is hardly an inexpensive sport. Designing and welding a cage unit and reinforcements into a production "body in white" on the scale of a superteam shouldn't be more expensive than totally fabricating a whole car from scratch. Moreover, production body cars could still be "clipped," so the repair costs shouldn't be that much higher. And strictly requiring stock body dimensions and factory body parts should eliminate much of the costs associated with developing and building special bodies for particular tracks (the COT was supposed to do this, but has failed because NASCAR doesn't use enough reference points on the fabricated COT body)

Re: Autoextremist: NASCAR May Return to Production Bodies and Engines
Speedy, I can only speak from my experience. Its from my experience that I form my opinion about the relative cost of unibody and tube framed racecars. Clearly from the standpoint of a NASCAR super team perspective, its probably "6 of one, half-dozen of another."
I suggest that you are underestimating the amount of prep needed to creat a competent unibody. It is far easier to lay some tubes and drape a body over it than it is to seam weld, hole drill and lay tube in an existing body shell.
But, I'm not a NASCAR team.
