Won't help with a vararam

 

The BMAD would still be functional even though they are two independent systems. Controlling engine temps , coolant, oil, trans, and recovery time are even more important at the track. This is one of the great things about the BMAD you can bolt it on in 2 minutes before your run down the track. Anytime you push your corvette like auto-crossing you want to have a quick recovery time to stabilize all your temps. All these issues are critical for optimizing performance irregardless of modifications.

Hhhhmmmm, consistent repeatable results with COLD AIR INDUCTION.

 

Edgar, this thing works. It will aid in cooling although you will not get any benefit from it for your Vararam like I did for the Blackwing. Look at the big picture.

There are guys that think our engines like a 200+ temp. You and I know better and every little bit helps.

 

Nah! Still sucks in more hot track air than the VaraRam

 

How would you quantify that statement ?

 

 

 

I would quantify that statement by stating that I have read many posts regarding VaraRam vs this intake, and that intake, and whatever. I don't agree with VaraRam's claim that it will give you +40hp, but I have gone consistent 13.1's with my old tie wrap mod (with K&N filter), and screened foglight shrouds to consistent 12.8's with the VaraRam. My VaraRam has the K&N filter, not the foam rubber one. That is my experience with those 2 products. I can verify it the performance gains with time slips.
I have only seen the Big Mouth in pictures, and read about it's attributes on the forum. From what I gather it appears to work on similar principals as the VaraRam. It may even take it a step further. Heck the frontal area of it is at least twice that of the VaraRam. Does it introduce more drag than a VaraRam? Simple physics states that more frontal area will introduce more drag. But here is the reasoning behind my statement.
All intakes of the type being discussed here have been categorized as 'Cold Air Intakes' for reasons I won't be redundant for here. If 'cold' air is the reason for the performance gain that is realized and there is no 'ram air' effect realized, then hotter air going into the intake will degrade it's performance. If the black asphalt of the track is 170 degrees and your intake is 3 inches away from it you will be picking up air that is heated from that asphalt and rising. As it is rising it is cooling. The VaraRam's intake is about 12" from that same hot asphalt, but has had a chance to cool more and therefore will have 'cooler' air entering into it. Next time you are at the track and it's sunny and the surface is 180 degrees put your hand 3 inches above it, then put your hand 12 inches above it.
On ram air effect not existing. None of the cams we use in our cars would not work if not for ram air effect. The overlap that is in every modern cam works because of inertia. As the air comes up into the ram air intake it gets accelerated. Since air has mass, that acceleration gives it inertia. That inertia gives the air charge more force. See Newton. That force causes the air to compress slightly. The filter diffuses some of that but not all. Manifold air pressure is less than barometric pressure under acceleration and that pressure is helped through the filter. It's slight, but measurable. I have measured MAP between 98kpa and 100kpa with my old zip tie intake that stays constant to around 130mph. I couldn't go any faster around here in NJ. With my VaraRam I measure 105kpa above 80mph. It starts to rise from around 58mph from 99-100 up to 105kpa. If I can measure it, it's there. I'll bet the Big Mouth has the same effect.
This whole thing about CAI's has been beaten to death. It works, I can feel it (SOTP), I can see it (time slips), and I can measure it (MAP).
Sorry for continuing the fine old tradition of...
I actually was just trying to have a little fun.

 

Where I live where instant flooding is a very real concern, and 6" of water occurs with any amount of rain in excess of .5 " an hour. no way I would put one of those things on my car.I do have 6 2.25" holes drilled in my foglight shrouds, and a modified stock lid with with about 90% of my filter open to incoming air.About the only drawback I have found is that standing front of the car noise level is higher at idle.The only way redirecting airflow from under the car does anything to reduce lift is giving it some place to go.Take a look at the C5R, that strange looking hood actually redirects that air and produces downforce.Tomorrow weather permitting I will run some temperature tests of incoming air at my filter and at the air dam at speed. I have a couple of lab thermometers from my days at the refinery, results should be interesting.

 

Great, this is information we can use. Thank you. I know what you mean about water. I don't drive in the rain anymore. But I have been cought in it and have been in one downpour with puddles and traffic. I will say I drove gingerly and was as careful as I could be. I made it home fine.

 

You should understand that units like the Vararam DRAW air through the inlet tubes. If they are submerged they draw water, not air. The Big Mouth does not draw air, only my filter does. And that sits high. You can submerge the Big Mouth and it will have no effect on your engine.

That plus the fact I could retain my Blackwing, which is an excellent filter is the reason I installed the Big Mouth. I then had the idea of cutting a window in the shroud to get more air to the filter. Everything worked great. I wasn't looking for a performance gain, only consistent ET's. I got both.

As I understand it, the Big Mouth was developed to aid in cooling the engine and to keep debris out of the radiator area. I took it one step farther and it works. Remember, it does not draw air. It funishes it to the radiator area.

 

Roger, thank you for all the detail , you are very astute. If you look at Nascars they have the identical set up as the Big Mouth. They have to large openings with a ramp leading into the radiator just like the Big Mouth. Our design is made to function in the same way to ram incoming ambient air into the radiator compartment . We are able to achieve this with a specially designed aero dynamic flange which you don't see in our pictures. . This increases the cold static pressure in your radiator compartment , in turn this quickens the diffusion process and will affect your liquids , oil , tranny, ect....Now with Bob we where able to take advantage of this colder static pressure by opening a window in his upper shroud where his Blackwing is located.He had instant gains in his times , in both 1/8 and 1/4 mile runs. He also has time slips and is very happy with the results ! That is not to say this is better or worse than other set ups , but If you think about it , it will make sense to you.

 

You won't say it but I will. It's better! Great filtering with my Blackwing and good performance.

 

Can you post a real picture of the big mouth by itself?

Thanks for the offer, but I would like to see what the actual piece looks like. Is that picture available?

 

The Best picture is on Ecklers web site , do a search for corvette1987 and then type in big mouth and look at the 4th picture and you can see the picture , thanks ! I don't have it in my photo buckit yet.

 

Eric, did you say you are running a special for the forum guys?
