ok so i want a intake mani, but i dont want one off a shelf. were in the world can i get a flange to make an intake mani? If need be i will buy a flage frome someone who can make one.
i applaud your attempts at this, however im guessing this is going to be a very hard process. and to make it harder you really need to make it a long runner intake unless you have FI or else you will lose a lot of torque.
So if you would want to make your own intake manifold for an NA car then you need long runners right. But how long should the runners be to get the optimal performance?
