Here is the ZL1 New Era Intake

[gbosh]

When someone thinks I'm wrong please look into the downforce as drag! Lift is generated from the hood and roof of the car,so the hood causes tubulance to defeat this effect and the pan is also raked at an angle to cause downforce,take the pan off and put a different hood on and see what happens,then you can say I'm full of it! What happens when you speed up air? Does the pressure decrease or increase? Look it up and reply back and lets see who is correct.

Thanks

Unfortunately, we did not run this ZL1 down the track prior to the New Era CAI and tuning, but we have been seeing trap speeds as you mentioned with stock A6 ZL1's (115-117mph), so that is a general assumption of a 5-7 mph increase in 1/4 mile trap speed, yes. And, trap speed is a better definition of acceleration and horsepower than ET.

The belly pans reduce turbulence under the car without negatively affecting cooling. Also, downforce is created by aerodynamic drag (friction) and the weight of a car. If the rear spoiler is creating 150 lbs of downforce at speeds above 150 MPH, it is doing this by causing friction as the car moves through the air.

The harshness was because he was speaking with arrogance and if he is an authority on the subject matter and used exclamation points to force his view/opinion.
Downforce is not created by drag or friction and is actually the opposite. Its generated by creating a lower pressure area (differential) which reduces drag and friction. This is why an airplane wing will fly or any other surface that has a pressure differential will change directions. It's also the reason why race cars are so low to the ground because it reduces drag which creates downforce and in turn generates more speed.

I don't think you're wrong I know you are. I'm an an Engineer by trade with 20 years experience so I'm well versed on the laws of physics and don't need to go "look into" what I've spent my entire career practicing. My clients are very happy with my knowledge and my work. You don't understand the correlation between downforce, lift and drag and you're actually viewing them backwards. The reduction of drag/friction is what generates lift due to the low pressure area and differential that's created (increased AND decreased airspeed/pressure on opposing planes). Once again...Bournoulli's law. And for every actions there's an equal and opposite reaction. What you're trying to preach not only defies the law of physics but also contradicts what every race team on the planet that's seeking more speed already knows and designed their cars around. Yes...you're full of it. Keep yelling and trying to force your opinion with exclamation points and see how far it gets ya. Now back to the regularity scheduled discussion on the New Era CAI which is the topic of discussion for this thread.


KDI/New Era...will there be a possibility of this unit being offered CF? And does this unit have a 4" bore?

3.9 ID on the tubing used for construction, each welded joint is internally hand blended to match. Air filter supports 1000 hp. Not available in carbon fiber, sorry.

Thank you sir. 3.9" is plenty fine. Was just curious on the CF. The matte black looks good.

The black on the CAI does look good, it matches the top of the intercooler.

[mike@newera]

Thanks, it is actually a wrinkle black exact match to the top of the blower.

Looks good, any installed pics?
