Cobb tuning intake test

one thing that does need to be taken into effect is when the car is moving i.e. not standing still on a dyno it creates pressure under the hood which forces more air into the engine bay. I have a feeling these short ram intake's do make some power granted it may only be 2-4hp but when moving under load in real world conditions i think they will produce something. Its the same idea on a motorcycle. because the intake systems are based off ram air they always produce lower numbers then claimed on dyno's because the ram air pressure effect is not there standing still. but they are faster on the track on the stop watch....

or we can just wait and supercharge or TT the 37's !!!!!!!!!!!!!!!!!!
If you guys are complaining about cold air, how about you get a carbon fiber hood with scoops that send air to the intakes ? Kind of like an airway specially directed to it the intake.... Or just roll around with some mfkn ICE LOL

Two Questions regarding this stuff:
1. You guys are talking about the increased HP of a moving vehicle over a stationary one... how can you measure that at all? I would think the only way you could try to measure that is put a dyno in the wind tunnel (probably next to impossible financially). or to hook up an airflow that would blow into the intakes at 60 mph or something? I just don't understand how anyone could really prove that the incresed airflow would help?
2. If getting cold air into the engine was such a huge factor in improving HP, why wouldn't anyone insulate their intake tubes? I woudl think stillen would be the wost offender as the metal would just conduct heat from the engine bay stright into the incoming air in the tubes?
