Dual Throttle Bodies? *no 56k*
Does anybody have any technical input on a intake manifold setup like this? The manifold is made to a style of a reversal merge collector (basically the opposite of an exhaust manifold) Can you go too big on an intake manifold? Which do you think flows better, traditional 'box' style manifold or the merge collector style? Would there be a negative effect becuase the runners are not equal length? (boost not getting to each cylinder at the same time)
sorry if pics are too big

Holy ---- that's crazy.
I'm sure you can go too big on an intake. Tinker built a custom manifold with a collector style. I'm not sure how it worked out for him, but he did it. You should contact him for info on it. www.lovefab.com

You would think a collector style intake manifold would have to flow so much better than a traditional manifold. Think of the increase in air velocity becuase the air would be traveling directly into the combustion chamber instead of having to pressurize a box. Kinda like the log style vs merge for exhaust manifolds.
The only problem I could see would be with the difference in runner length boost would not be equally distributed at the same time. Therefore the first couple of cylinders would see boost first while the longer runners wouldn't/

Re:Dual Throttle Bodies? *no 56k*
The way I look at the stock manifold is that there is no direction for the air so the velocity is not directed towards the individual cylinders, instead it hits a wall and pressurizes the box than the compressed air is forced into the cylinders. Think of it as water instead of air. If you took a hose and sprayed it into your stock intake manifold it would hit against the wall of the stock manifold, loose its velocity and equal out the pressure to the cylinders. Now if you had a merge collected manifold with individual runners you would maintain the velocity and shorter runners would make the water reach the cylinders earlier. Doesn't it make sense?
