Ported Intake Pics - Does this look right??
I'm looking inside my ported/polished manifold from TVT Design and it's WAY different. Can any of you tell me if there is a piece missing or if it's just REALLY ported? It almost looks like part of the manifold is missing. Attached is a pic of my old inside and 2 pics of the ported one inside.
Do you think having this piece missing would be a performance improvement? I'm a little concerned...

Thanks!
If at all possible get a dyno before and after. This has not be performed yet.... and is keeping people on the fence about this mod. Just no hard data yet.
So I finished! But the car is running like crap. It shakes hard and won't stay cranked. I feel like I may have screwed something up. I disconnected the air pump on the front (California requirement), but I'm not sure that's the problem.
Thoughts?

Anyone of these could create that issue.
Go back over everything you did visually, checking for lose or dissconnected connections...... I suspect a coil pack or two are not connected tight, or mass air meter is not connected right, or possibly the intake mani gasket is pinched or is leaking somewhere..... there can't be any leaks in that intake manifold, or you'll get problems.
And last but not least.. if it's out of gas......

before/after dyno would have been great but something tells me it will never come to fruition.
The choice that TVTdesign made to remove the variable intake runners was a very poor decision in my opinion. Definitely a half brain solution to intake improvements.
Glad the car's running with no major damage....only a few months of downtime and ~$1000 wasted. Don't buy parts from vendors with little/no history!
Anyone want to buy and reseal the other one? Be my guest!
I haven't installed the headers....the lowest quote I've heard is $1k and it isn't even CLOSE to worth it. I may do it myself or forget it based on my last low cost tuning experience...
