Done and Done.

From a guy who ports almost everything, I wouldn't port that. I have never seen the purpose of porting those intake mani's, the plastic ones, just doesn't seem worth it.

Doesn't FAST make one yet for the C7? If you really want gains, I'd do that.

Not yet. It looks like the first aftermarket intake manifolds to market will be MSD ($1100, April) and Weapon-X.

I somewhat agree...but it almost pains me to leave it alone because as you know, I also love porting anything I can get my hands on! It is without a doubt the best stock intake manifold I've ever seen though.

You'd think with a ported TB you could at least hog out the inlet and see a few whp gain? Can that be done w/o removing it? Quick/dirty, that's what I'd do on a CT9A if I were to do it all over again with a ported TB.

Damn it stop giving me ideas. :P

The ported throttle body just removes the lip and smooths things out pre-plate, the diameter post-plate is left about the same. Let me go double-check my throttle body pictures to confirm that though...

[scheides]

Yea doublecheck that otherwise I say wait for a proper aftermarket manifold to come out...what are the other v8 guys doing traditionally?

or if you really wanna stick NA look at doing a big gnarly cam (I know you won't but I'm still throwing it out there)

Seriously though yea KISS--don't do the IM unless its really worth it.

[Kracka]

No long-tube headers and definitely no cam :) Drivability needs to remain 100% stock-like with little to no additional noise in Tour mode (muffler baffles shut); these are my self-imposed requirements.

As of right now the C7 guys are just porting the stock intake manifold as there is nothing yet available in the aftermarket (or simply leaving it alone), but results have been mixed and I've seen nothing mega concrete yet in terms of gains. The C6 guys either port the stocker (totally different design), or get an aftermarket and have that ported (FAST, MSD, etc.).

[Kracka]

Well, I couldn't leave well enough alone :)

I sent the stock intake manifold core in to Fasterproms in Florida for them to do their thing on it.

Porting is always tough to judge in pictures, but I'm very happy with the craftsmanship and finished product. The inlet and runners were all enlarged to gasket size, the vacuum/draft tube was removed, and all edges/lips were smoothed. This is what I would consider to be a "stage 1" level of porting, kind of like a Buschur intake manifold vs. a MAP Rev2 & 3. WeaponX (I have their ported throttle body) offers what I consider to be the stage 2 & 3 levels of porting, but for my plans the additional expense wasn't justified IMO.

I have a buddy coming to town from Arkansas next weekend to pick-up his Evo X build from Cobb so while he's here we're going to get some wrenching time in and install this manifold. Once I get the retune finalized, I plan to dyno again at Cobb since that's where I did my stock baseline at, then call my setup good for the year and just enjoy the hell out of the car!
