Honestly, I'm starting this thread about this rule change proposal, to drum up support from SCTA members and clubs. I'm hoping discussion on it will help clarify the intent, and lead to a rule change. So please, if you are an SCTA member, voice your opinion, ask your question, or make suggestions here. Here is the proposal. It's short, as we are limited to a word count on the proposal form: Rule Definition: 4.R, Page 44 Rulebook issue: 4.R A hood scoop is a functional air intake device used on full body, un-blown vehicles, where allowed. No part of a forward facing hood scoop can extend forward of the leading edge of the hood, be more than 11" above the surface of the hood at the centerline or extend past the trailing edge of the hood more than 11" at the centerline. I believe a scoop on a blown car should be allowed 11" above the blower intake, not the hood, so to have the same advantages as on an unblown car. Desired outcome: To give blown cars the same advantage/disadvantage of 11" clearance over the hood or air intake, depending on which is higher. Reason for change: Unblown cars are allowed a hood scoop 11" in height over the hood. A blown car often has an intake sticking 6' or so out of the hood. I believe blown cars should receive full benefit of 11" over the intake, in that case, not the hood. If a blown car has a scoop taller than 11", in Comp Coupe, instead of the 11" behind trailing edge of the hood, it must end at the cowl. I believe blown cars should receive the same advantage/disadvantage of 11" clearance of whatever is higher-the hood or air intake. Any side effects: Side effects will be innovation, restyling, and more efficient hood scoops. Desired rewording: A hood scoop is a functional air intake device used on full body, blown and un-blown vehicles, where allowed. No part of a forward facing hood scoop can extend forward of the leading edge of the hood, be more than 11" above the surface of the hood at the centerline or extend past the trailing edge of the hood more than 11" at the centerline. Blown cars are allowed 11" above hood, or air intake, whichever is higher.
I wouldn't think you would want a scoop,if your car doesn't have a blower. Less drag? Would a scoop help the horsepower more than it would effect the drag? I can see a blown car wanting a scoop,for maximum air intake. Correct me if i'm wrong,but a blown car wouldn't be competing with an un-blown car,right? Two different records,right?
[FONT=Arial, Helvetica, sans-serif]Bob, here is the current rule. As you can see, it address ONLY unblown cars, not blown cars:[/FONT] 4.R A hood scoop is a functional air intake device used on full body, un-blown vehicles, where allowed. No part of a forward facing hood scoop can extend forward of the leading edge of the hood, be more than 11" above the surface of the hood at the centerline or extend past the trailing edge of the hood more than 11" at the centerline. Unblown cars use it to direct air to the intake, AND for aero. They are allowed 11" over the hood height, even though nothing sticks out of the hood, and can be 11" behind the trailing edge of the hood, but have to be at least 1/2" from the windshield. Currently, on a blown car, we are held to the same 11", regardless of how far out of the hood the blower sits. Seems to me, we should be able to go 11" over the top of the highest point sticking out of the hood. It sounds petty, but there is more too it. If you choose to make the scoop taller than 11", it would have to be in comp coupe. In addition, the scoop would then have to end where the cowl starts-a HUGE aero disadvantage. You're right-blown and unblown run different cl***es, but currently, the rule book only addresses hood scoops on unblown cars.
Hey, Buddy - You might want to point out that the deadline for a rule change consideration is September 1st. I don't have a dog in this hunt, but I'll cut and paste your wording and join you on the change.
Chris, to clarify, September 1st is the deadline for rule change proposals to be submitted. They will then be reviewed, submitted to the clubs for review and voted on. In November, they will go before the board.
Thanks TV! The following is in response to a post on another board: I agree, that the way Ive proposed the word change, it would only work for Comp Coupe/Mod Sport . Those should be fast cl***es, so if a team benefits from aero, great! That is what this is about right-rounding off every corner to try and go faster? If a person is running a lower profile car, like a Camaro or Firebird, the 11 rule allows for the scoop to reach about level with the top of the car-a pretty good dual device, that allows for air intake, and aero. Running a higher profile car, has its disadvantages, one of them being the hood scoop allows for less aero. Our scoop fits over the birdcatcher, and directs the air into the mouth of it. Does the scoop give us some aero? Absolutely! From what Ive seen, almost all of the scoops out there are being used for aero, even if the main purpose is air induction. Im simply trying to even the playing field. I like old iron, and would like to see the old iron running in the faster cl***es, not just Vettes, Firebirds, Jags, etc. I dont think the fact that aero could be benefited from this proposal makes it taboo-rather, I think it should make it more attractive. Well, unless one has a record that would be threatened, then I suppose it wouldnt sound so great!
People have made blown cars work with scoops that fit --on the salt for years. How do you think someone is going to feel if your rule change helps their previous record get broken? and yet they were able to make that record within then rules that stood for years?? You can keep changing the rules to make your car go faster, but then you are breaking the cl*** and innovation that stood for years that brought those people records. Just something to think about.
Au contraire! The cl***es I run in all now have records set in the last couple of years. On top of that, I'm NOT trying to change a rule that has been around a long time, but a relatively new rule. Rules change EVERY year. Some we agree with, others not so much. Rest ***ured, this is not simply about my car-the hood scoop rule is now written for unblown cars only.
