Cool, what would be the calculations for the runner lengths, plenum etc????? And also at what HP would this be a must???? I am going manual very soon, and will very soon be looking to go 500Hp, or at least what would be the max for stock internals (at least for now.)??? Anyways, I know everybody says that the stock intake manifold is good for upto like 400HP??? But I think it just looks kinda ugly, even polished. Would be so much nicer with a straight unner round plenum, or bendt ruenners round D shaped plenum. That just looks sweet. Throw on some internal velocity stacks for that little extra, and direct port watrinjection with second fuel injectors upstream of the main ones. That would just be super setup, low boost very streetable, not too much fuel etc. Flip a switch, and second set of injectors and the second map on the (civinco) kicks in. Add on some water with that and the sequential turbo setup. Your on the road for low, mid, and high end torque/boost all the way. Rebuild the engine, o-ringit, and go blowing some steam. Prolly overdid it alittle here Thor
