Modified 1g intake manifold

[VtecGoWahhh]

I was given this intake manifold for free. Seems pretty legit. I'm assuming with the large volume box plenum and the smooth runners, it should be better for my mid range and top end. What are your guys opinions on this. Worse then the oem 1g manifold or more Benifical then the oem manifold

Sharp corners normally are a pretty bad thing for flow. They create a lot of dead space near the corner where air doesn't really flow, and can create weird turbulence. Who knows if it's better than the 1g without testing it in a way that you can actually gather metrics.

Stick to the stock manifold. Buschur did something like that on the Evo. It lost power pretty much everywhere except at the very top.

Considering the Evo manifold is a better design than ours, I'm willing to bet it'll perform way worst than he saw.

like he said stick to the stock and clean up the porting ...
