SAIL?.........who came up wi th tha one?.........I did..........a few years ago we tested differnet scoops on a couple of cars..........found that the Hemi scoop and some of the larger/taller scoops actually took et off and a couple of mph.

Fugly: I am sure Bob is very knowledgable and his car is top notch. I always listen to good advice, that is why I ask. So I re read his post just to make sure I was reading it correctly. Everytime I read it I never seen in there one time that he was giving advice as much as he was saying I wasn't following the rules. So I am going to take it he is calling me a cheater. That is one thing I am not. Everything I have done to my car I have gone out of my way to make sure that I am following the NSS/NHRA rules. IF he would have wrote and told me that the use of an air pan is not allowed per NSS rules then I would have taken that as advice. I would have said thanks a lot for the heads up.
This happens all the time: I stick up for myself when someone makes some back handed comment and I become the bad guy.

I run a period correct reproduction hood/scoop 66/67 fairlane setup with a reproduction 2x4 air filter sealed setup. Trying to keep the nostalgia look from the era, as this is part of what the spectaters come to see. ...........I don't read anything into that statement other than what Bob prefers to use,that's all he was saying.Now where do you see where he's accusing you,or anyone else of cheating?

I would think that a flat hood or a cowl or teardrop (rear entrance) style scoop would be the best as far as aerodynamics and not hurting MPH. Any front entrance scoop would have to cause some turbulence. The question is does the forced air into the carbs add extra HP to make the car in fact faster??I would bet in most all cases Yes.

Well since this thread was about "AIR PANS" and not "WHAT SCOOP DO YOU PERFER TO USE"
This statement "TRYING TO KEEP THE NOSTAGLIA LOOK FROM THE ERA, AS THIS IS PART OF WHAT THE SPECTATERS COME TO SEE." This statement sounds like he is telling me(the one who asked about air pans) that I am not keeping within the way NSS wants to be represented.
I get it Bob has been around for awhile and I am the new guy. So I would like to say to Bob "I am WAY out of line for looking into this statement too much" Now we can get back to talking NSS racing.

Wedgie, before you have another "meltdown" you should be aware that the racers on this site are the most knowlegeable and respected individuals in the sport. You should be extremely grateful for "any" information they give. Back in the day, you would have been on your own...and getting your butt handed to you at the track... "RELAX"...

Hey........there is nothing in the rules that says NO air pans............some use em, some don't. 5 inch scoop max in NSS.......that is all. The rules IMPLY that they want all to LOOK period correct...up to a point..........F/X in some classes allow more. Wedgie, you are ok..........give it hell.
I think Bob was only saying what HE runs......not trying to slam anyone...he just is not the type. We have known Bob Moser for many years and he has always been a perfect gentleman and just is not geared any other way.

You are correct in some cases..........Given enough horsepower, a boxcar can be made to run in the low 9s...lol , but we tried the scoop test whith an 11 second car and a mid 9 second car........both showed a decrease with the SAIL scoops...

I fabricated an air box for Harolds Spirit. It sealed to the hood and was open to the cowl vent (like the NASCAR guys do) ...... no scoop. The car slowed down 1/10 and about 4 mph with the box in place. We know it was getting plenty of air because it would bow up the back of the hood at speed with the box in place. Tried rejetting.... nothing helped. Put everything back to square one and the car went back to running like it used to! Never could figure out why it slowed down that much by getting fresher air to it.
My old 65 Chevelle I ran back in the 70's with a snorkle scoop ran a lot better with an air pan. It would slow down without it.

With those real short factory scoops I could never see why they called it ram air. Maybe cooler air. Too me a hood is like a airplane wing and creates a dead air space. So that scoop needs to be up a few inches atleast. That NASCAR idea would almost act like a vacuum. Just Me Talkin

Actually the area right at the base of the windshield is a high pressure area. That is why the NASCAR guys pull in air from there, no scoop on the hood to slow them down, and why the hood would bow up at speed..... lots of air pressure going in there. That just the wind tunnel talking....  |

Like Mark says -- I think my cars will go slightly faster with a 4" scoop over a 5" scoop -- as a 4" scoop will get you plenty of air, and a 5" is getting to the point where it is an aerodynamic issue of catching more air than the carbs can use. I'm sure there is a speed where this gets to be a bigger problem. That was the whole purpose of my question on scoop size.
I see about half of the drivers (Drag'n Wag'n for sure) using air pans -- and I've never considered that anyone would think they're illegal.
I don't currently have one on either Coronet or the Whale because I have fiberglass hoods on them and afraid I might over time weakin them. However, I do need to fabricate something for the Vitamin C to test, as it has a steel hood.

1st off I would like to say that I am very sorry to everyone on this forum for my MELTDOWN. There was no call for it. I guess I just looked into more than it needed.
2nd: I know that the guys on here have alot of knowledge to give. I read all the post even if they have nothing to do with me just to see what I can learn.
3rd: It won't take any special secrets or tricks to beat me. I may have to run a "B" car in the "C" index because my lights are BAAAAAADDDDD! I am not saying anything bad about "C" index cars just my bad driving. So keep the knowledge coming.
I got up this morning and was reading this post. I cannot believe what I was reading. This is the only thing that I can come up with:
I have been off work for about a week. My back has 2 budged disc that have to be operated on soon. I am on some killer pain pills that take about 1/2 the pain away. I get very cranky and have no reasoning. I am so embarrassed.

Thanks
The only real reason I was going with an airpan is before I thought out a plan on cutting a hole for an tall aircleaner I made the hole to big. I figured I would run one just to kind of cover up my screw up so hopefully I cam make it look like I meant to cut it for an airpan. Worth a try.
I guess when I get back to the track I will just have to run the car with and without the pan to see what is what.
