Joe117,
VIPAIR is now like SPAM?? Joe you are so funny! How do those K&N's that you bought just for looks work Joe? Did you know that Russ has irrefutable dyno proof that K&N's do not work? If this is the company I keep in products that do not work than you GOT ME Joe!!
The basis for which I think that RussM's test is invalid is the following:
"We then decided to eat lunch and show once and for all how so many people get abnormaly high numbers when compared to others. The pulls from here on out were all made with the hood closed and a single 90mph fan blowing into the naca duct."
Russ is artificially feeding 90 mph air directly into the NACA duct instead of having the fans only orientated at the front of the car ... all fans should be directed at the front of the car to simulate the airflow as if the car is travelling through the air. Not directed directly at the NACA duct, why because as Russ stated...

Russ,
How do you explain the fact that your results are different than those measured by the GTSR Lemans developers at Chryler? Didn't they find that there was a vaccuum situation created at speed with the stock airbox and NACA duct?

Yes they did but that was on the outside of the hood. They discovered that the air pocket arround the naca duct at certain speeds restricted flow into the duct.
If this is the case then Russ knows that air should not have been introduced via the NACA duct, air should only have been blown at the entire front of the car only.
As for how much horsepower affects ET try this calculator (
http://www.douglevinmotorsports.com/HP_calc.htm ) supplied by Doug Levin Motor sport, thanks Doug, enter vehicle weight approx 3550 with driver trap speed of 122 and Et of 12.0 and then try ET of 11.8... the difference is approx 21 HP, WOW!!
Russ if it makes you feel better to sell the Vipair and keep the cash do so, I ahve no hard feeling towards you, I just think that the test could have been done better and in a way that closer simulates real world driving, and then you would have gotten and increase just as you did when you opened your hood you got a horse power increase, this proves that more cold air got into the engine as compared top having the hood closed.
