intake manifold selection http://m.ebay.com/itm/181614204353?nav=SEARCH
So I found this intake on ebay and was just wondering what you guys think of it for a boosted car or if I should just go with somthing different? Thanks for the help

I would avoid those. Short runner and large plenum so you'll lose lots of part throttle torque and torque out of boost. Low and mid range will suffer all together. You'd have to be turning some serious RPM or moving lots of air to actually see any benefit to those.

Marginal yes, but looks like a decent 800rpm more available.
I'd imagine with some boost any differences at the lower-mid range would be far less too provided you make some boost from say 4k+
For the cheap fabricated intakes though, it does look better than some of the others

I'm still not sold on it being much better in boost. You would have to be running enough boost with a good enough backpressure ratio to make sure intake velocity stays high before you would start to see it pull away from other intakes.
If you are going to push a 4 bolt hard and have a a lot of turbine capacity it looks like a winner to me
Going down the track with the motor shifting at 7.5 dropping down near 6 it will be happy, hg will too.

Thank you for the help guys love the comparison charts my friend building a 370 with a s366 I think is what he said sent it to me in a link and got me thinking about one for my 408 with an s480 would the change in ci be big enough to bring any difference? Or would I be better off looking in to a holley carb style intake?
There are 2 versions of this intake that look identical from the outside but the one posted is a new version with bells on the runners. Can you confirm which intake was used in your testing?

They do have quite a few tests on that OnTheDyno page and FB page, but not aware of any boosted tests with those intakes.
I would think though that one we start to see some decent positive pressure, any losses with the sheet metal intake would probably be less vs the plastic.
So it should be a win win unless it was a fairly large cam or particularly laggy setup. In which case it might help to tune n/a as best as possible to keep performance good off boost and then let boost take over at the top end as it will tend to do anyway
