Intake Manifolds

[briand]

i agree with 1bad89 when he states that the edelbrock intake by itself will not give you 37 hp by itself. Maybe with heads, exhaust, tb, and so on...... it will net out 37 hp. but i don't have a problem believing that a intake will drop 3 tenths of a sec. I have no problem believing because i experienced it myself. Before i put my heads on i knew i was going to change the intake so i went ahead and purchased the cobra intake and put it on with the stock heads. I did have the exhaust already done, and gears and so on. So i thougt well since i have air going out pretty good, it couldn't hurt. So i put it on and went from a 14.80 to a 14.50. My mph went from i think from 95 to 97. I don't believe the hp from the intake did it by itself. I believe it was super ford who did a test on all intakes and found that the cobra, edelbrock performer and maybe the gt-40 gave more cfm's per inch which made it a more efficient intake and it flowed more air. So i believe that not only the added flow but the more cfm i got at lower rpm made the difference. Its kind of like extrude honing a stock intake. the bores don't increase much but effiency of the intake is increased to give more performance. maybe this sounds like a bunch of bull krap but i know it did help my car.
