this is interesting, I had to really open up that area, along w/ making the whole opening bigger, to even match the gasket on torquer 2 intake, for a f.a.s.t. 2.0 throttle body. if I hadn`t the injectors would have been over alum., also made tried to make the little runner openings, bigger to match the flow of the tall openings on it. hughs said the diff you can see is why there is so much flow scatter. any one else do this stuff that really knows what their doing. had the thing partially flowed while doing it, and was told that " I definately wasn`t hurting it. would like to see any pics of others work. haven`t taken time to learn how to post pics of my own, maybe when I retire and have more time.
