Cowl induction for cold, ram air for the Si?

How is it pointless? Even if someone comes out with a new intake like X had, no one has addressed utilizing the cowl area to access air from a high pressure zone. I am still going to pursue this regardless of what comes out.
I threw this out as something that we could look into.

I am glad for others that they have more choices now. A lot of people don't want to have to deal with fabricating something. I am interested in doing that.

I am still on the path of how to create stuff. Well I got a wonderful idea well looking into building my computer case. We could use acrylic sheets to form a airtight box around the filter. Acrylic is easy to work with, cheap, and looks slick ass snot. You can buy a 2'x2' sheet of 1/8 acrylic for say $15 and the apoxy (wich basically welds the acrylic together) for another $10. Plus it is a super dense, heat resistant plastic. Wich would mean less heat soak.

They also make tubing (wick isnt hard to bend at all). So ahh if anyone is still pondering this there is some more info for ya.

The acrylic sounds like a possible material to use in the construction of the air induction box. Link us to something about the material.

Good point. Automakers have the ability to measure horsepower in a windtunnel or through on-board measuring devices at speed. For us, it would be hard to see which one makes the most power. The only way to test it out would be to do a comparison with a stock airbox, an aftermarket intake and a ram air intake at a track, either at a dragstrip or road course.

I'm down for making this. Mounting it shall be interesting!

Yeah, I forgot about that. It is about the only affordable on-board device that we could use. Plus, they work extremely well. For sure it could be used to test out different setups.

I have no idea what you are trying to say. Who's laughing? What's with the genius comment? Is that directed towards me or towards X factor?

I'm sure x.

I've seen it already. Looks pretty good. You could either direct the intake tube towards the cowl area or to the lower bumper intake area. I really like the enclosed air induction box. Looks promising!

How would you do that with the TR1 intake?

Paul, where the inlet tube is, which could be directed downwards towards the front, I would instead either use that tube and make a 90 degree turn or put a silicone tube with a 90 bend in it and attach to a duct on the firewall.

IDK how you would do that, Id just keep it in the bumper area for two reasons, one, I honestly think you would get more pressure coming directly from the front of the car verses in the cowl area, and second, I already cut the hole out of the fog light cover hehe, But I really like that T1r intake. My credit card is hoping its not too expensive hehe

This is a tough one to answer w/o having aero numbers and pressure readouts at the bumper inlet and cowl. Most race cars that are front engined draw air in from the cowl area. Chevrolet found the pressure higher in the cowl area than in the intake area.

We do know both areas are great to draw air into. For me, the simplicity of the connection to the cowl would be a plus over routing down. Also, the tubing would be straight and shorter.

you would have to have a 180 degree bend out of the hole in the bottom box in order to reach the cowl area. That is a pretty tight bend that isn't going to help the flow of air. Or plug that hole and make a new one at the back of the box.


I'm starting to think you are taking the cowl induction thing a little to far. There has got to be a reason why car manufactures don't use cowl induction any more. They always use an inlet at the front of the car to get the ram air effect. Corvette, Viper, SLR all use a ram air inlet at the front of the car. Its 2008 not 1968. The reason NASCAR still does it is because it is a rule not because its the most efficient means of sucking in air.

Paul, I can give you one reason why cowl induction isn't used today: packaging problems. Most fuel injection inlets on V8 or V10 cars are at the front of the motor pointing forward. It was be near impossible to reverse direction and space is tight as well. I have commented at length earlier about the Viper and Corvette in particular.

I disagree with your assessment that it is not the most efficient means of drawing air in. Quite the contrary. Anytime you have a duct at the front of a racecar, it will create additional drag. Also, any debris on the track will be sucked up into the intake. With cowl induction, you get air coming at a high velocity w/o any drag issues or sucking any debris into the motor.

I am not sure where you get that 180 degree bend. Look at the picture: The air inlet is on the side of the box. How hard would it be to just make the tubing go backwards rather than downwards?

If the cowl area wasn't a good area for air induction, all the car manufacturers would not be using as the source for ventilation in their cars. They would be pulling it from the fenderwell or front of the car if it was that much superior.

Hello everyone...

I found this website that can help you create an intake box. It can be plastic, fiberglass, etc. I look at the price and it doesn't seem too expensive. Maybe someone might want to check it out..

Fantastic. If we give them the dimensions and the exact locations to place holes, we could have one custom made. Man, I would rep you if I could. Just picture 8 balls plastered under your avatar!
