Nissan 370Z Forum - View Single Post - DIY: Fang Vents: Forced fresh air to your airbox

only thing i dont like is it looks like your sealing the ducting to the air box? making it the only way of air getting in. wont that basically make it have to suck through a straw to get air at idle and low speeds. though that doesnt seem like much but im pretty sure your hurting the performance through a good bit of the launching untill certain speeds are hit. ive seen setups like this and watched cars lose power because of that until certain speeds are pushing enough air in. have you actually had the car on a dyno with that setup? cool air is good an all. but it the engine is actually having to struggle to get the air its not helping. you need something to actually monitor air CFMs and see if its actually helping or hurting. but i could be wrong. but that happened to me and a few others on our grand prix bck when i had one. the intakes are very similiar to the Z other than only having one box.
we had places at the bottom of our front fascia perfect for ducting. but it turned out because of the length of tubing the engines were being starved of air.
