Straight cut velocity stacks, for example, pose a unique problem. Exposed to the outside air, velocity stacks experience a phenomena that actually hinders performance at high speed. We are referring to stacks and air horns that protrude through the hood and extend into the air stream so the direction of the air rushing over the car is at a perpendicular angle to the length of the tube.

Air moving rapidly over these stacks create turbulence inside the opening. At high speed, the rushing air tends to create a partial vacuum inside the tube. The condition is counterproductive to air flow. The phenomena also effects open carburetors. The higher the ground speed, the greater the problem. Vacuum created by the engine is trying to coax air into the cylinders and the high speed air flowing over the open end of the stack is causing resistance.

Asta scrie pe site-ul K&N (http://www.knfilters.com/facts.htm) nu ca as avea eu incredere foarte mare in ce scrie intr-un text "de publicitate" dar nu vad ce interes ar avea K&N in a discredita prizele de aer (priza de aer nu exclude filtrul de aer).

Nu sunt fizician deci nu pot spune daca o priza de aer creeaza sau nu un vid de aer la viteze mari... Oricum, din cate am inteles eu chestia asta se intampla la "High speeds" ceea ce nu stiu exact ce inseamna dar daca high speed e 150 atunci nu o vad ca o problema foarte mare (daca de la 150 nu accelereaza foarte tare dar pana acolo mananca pamantul eu zic ca e OK).

O alta intrebare pe care cred ca am mai pus-o e: ce se intampla cand ploua ? Ploua direct pe motor ? Chestia asta nu afecteaza motorul, bateria, bujiile, filtrul de aer, etc ? Sau e filtrata apa cumva ? daca da cum ? Filtru de aer ?
