C/Pro Bonneville Car

[Samaleshi]

Can someone give me a quick rundown on the allowed body mods for the subject line class. Without an actual rule book, the best I can do is; original panel placement, height, width, length. Are front air dams, rear wings, shaved drip rails, etc. allowed? Any help would be much appreciated.

Not in Production. You can do ANYTHING to the engine as long as it has the stock-type castings (basically, a type of engine that would have come in the car). Remember, the engine class is determined by displacement, not modification. If you run N2O, you're in fuel, and I'm a bit fuzzy on factory supercharged cars - I suspect they run /BPRO (blown production) but that's a guess.

Any non-production body mods (spoilers, air dams, etc) puts you into Altered. If the body you're running had available a spoiler or some such, you can run it - I'd bring proof the first time. For example, I could run a Z28 spoiler on my Camaro and still run PRO (my car is not a Z), but the picnic table on the back of mine puts me squarely in ALT.

Now - this said, all these observations are for Maxton. I think this pretty well applies for Bonneville, too, but hopefully one of the B'ville guys will chime in and confirm and/or deny.

Re: C/Pro Bonneville Car

Thanks. My twisted brain is currently stuck on a mid-60's Barracuda Fastback. My limited aero imagination hopes that the barn door front will be slightly offset by the teardrop rear. I usually fall back on nature, i.e., rain drops, fish, etc. That, and I could build a screamin' sixer for it. Probably shoot for F class. Feel free to beat me up...

Classic Production class 1928 -1981, ,is the same as late model Production, 1982 - present. As mentioned, height, width and lenght un changed from stock. No body add ons such as spoilers, wings, air dams that were not OEM are allowed. There is currently no record in the F, up to 183.9 ci, class so two consectutive passes will get you a record. Of course this depends on being the fastest of all entries in the class.

Production Spercharged class requires the same type of blower as OEM be used. If the car as equipped OEM did not have a blower you cannot add one to change class.

Re: C/Pro Bonneville Car

Do unlimited engine mods include fuel delivery? I'd prefer injection to make up for the altitude and I'm assuming it would make it easier to switch from gas to fuel(alcohol/methanol) and such. I'd like to run in gas and fuel classes and production and altered. All within the 183 CI window. I'm thinking an injected dry-sump slant six.

Re: C/Pro Bonneville Car

Electronic fuel injection isn't allowed... but you can run Mechanical in the Classic category...

I was hoping Dan W would chime in. My knowledge is, at best, incomplete. Thanks Dan!

How does injection make up for altitude?

There is no fuel allowed in Production classes.

What bodystyle do you want to run? That would clarify some of your other questions.

I know you're busy Dave.... ;D

That was a poor way of stating that I thought it would be easier to adjust for altitude with EFI. I'm way behind the curve on it, but my thinking was it would be easier to make on-the-fly adjustments and set-up multiple fuel maps before hand. I'm also concerned with getting optimum fuel distribution for the six. Currently I'm leaning towards multi-carb, I just can't decide how many.

All, thanks for the replies, I'm trying really hard not to get addicted to this forum, you're not helping one bit...especially hearing from an actual inspector. Thanks again guys. I'm coming to SpeedWeeks this year and I'm going to order a rule book real soon.

Re: C/Pro Bonneville Car

Hate to shoot your plans down but, EFI is not allowed in Classic clases as DF alluded to. Using EFI will enable you to run in Gas Coupe and Gas or Fuel Altered. Altered class allows you to do extensive body mods such as air dam, spoiler, etc.

Records look like this:

F/BFAlt - 251
F/FAlt - 173
F/BGAlt - 255
F/GAlt - 173
F/BGC - 202
F/GC - 107

The F is the engine class, following the / is a B for blown(no B unblown), F or G for fuel or gas, Alt for Altered body class, GC for Gas Coupe body class. The rulebook will show the body mods allowed. To run the above classes you MUST use a non-OEM EFI system.

Re: C/Pro Bonneville Car

Dan, if it is a '66 Cuda with a Slant Six, then would it not run in regular Production with EFI? Or Classic with carburetors? Wouldn't it need an engine change, a non-stock supercharger, or a quickie rear to run in Gas Coupe?

[dwarner230]

Re: C/Pro Bonneville Car

Yeah, you're right, I was stuck on the EFI deal. Never mind.

He can run F/Prod with EFI or CLassic Production with carbs. Body stuff still goes for Altered.

Re: C/Pro Bonneville Car

The F/Prod record is 167 mph. I'm guessing that takes at least 475 real horsepower in an old Mopar? So that's about 2.5 hp/ci on a 183ci Slant Six on gasoline?

I'd go with carburetors for the open record in F/Classic Prod.

Man, you must be a tech inspector, already apologizing for telling me my plans won't work. No worries, I'm on here to get a basic feel for what I can and can't do ILO having a rule book at the moment. If I was standing in front of the car at the break of dawn after 2 weeks of no sleep I'd be really upset. Which is why it's so awesome to hear from the man over these here internets before showing up. Thanks again.

That's the same thing I was originally thinking. It doesn't matter how many carburetors correct? Besides, F/CPro sounds cool. Now I just have to decide on a name...
