i'm saying that the only time that it would make a difference would be when the throttle is at or near wot. i hope that you dont do your daily driving at wot all the time:squint:

so, lets say w/o an intake, you have to open the throttle 50% of the way open to maintain a certain speed, or accelerate at a certain rate. hypothetically, with the intake, you would prolly have to open the throtte about 45% of the way open to maintain the same speed or accelerate at the same rate because there is less resistance in your intake, but you would still get the same amount of air going thru the engine.

but if you are racing your engine and your throttle is near/at wot, with the intake, you can actually get slightly more air into your engine. even then, its not enough air to blow off you exhaust. how much hp do you gain from an intake, 4 or 5hp? about 5%? that isnt going to blow your exhaust off.
