I love the sound of the ecotech at high rpm, sounds really throaty like a modern sporty V6 for some reason, heaps better than the original Buick
i made an awesome mod to my vn air intake and now it roars at high rpm and past about 2/3 throttle
sounds mad!
anyway i took the bottom half of the airbox out and cut off most of the front and back sides, just leaving the base, the upright corners and the rim around the top
bolted it back in and bingo! free power:
burns rubber even easier in first gear cuz engine spins up faster
roars nicely under load
revs quicker in neutral
downshifts are WAY smoother - 100km/hr shift from 3rd to 2nd - can barely feel it, engine revs up smoothly and quickly. there's no jerk at all like you get normally with a big downshift
dyno testing has shown decent power increases in a mate's VQ caprice (stock 5L except full exhaust system and same airbox mod as mine)
hope that was helpful to someone..
cheers
