Ported Intake Manifold

All porting is doing is taking the original product and just making it flow better where the cpr6 or the v8's fast manifolds are built from scratch. How much we will gain is all depending on the knowledge and skill of the person that is porting and how much the original manifold was choking. From my experience you usually see about 10-15 on avg and mostly on top of the rpm, and usually there's different stages of porting that a vendor will offer. Usually stg1 thru stg3 which will be the most aggressive porting or removal and usually requiring a tune. I am currently working on the most aggressive stg with tune already lined up. We are expecting 20+. The peoples that I am having my porting done from are anticipating around 25-30 but I think I feel more comfortable saying 20+. Only dyno will tell and I will make it happen.

We said it before and it is worth saying again. THANKS for taking this on.

I can't wait to see the results. Is this something you think we can remove our intake and send it to them for the work and then re-install. My Camaro will be in storage all winter and I can see removing this in December and shipping out for the work and reinstalling upon return. Let us know the details (which I know you will) ASAP.

Thanks again.

This all sounds good! So we, those of us without a tune will be required more than likely to get one with this? If that is the case, aside from Trifecta, where would this come into play? I had thought about a tune but didn't get the questions I had for Vince answered to my satisfaction with spending that kind of money. Maybe that'll change but I'm open to what will make the car perform to its fullest potential.

Without head porting to match to the intake there will be some turbulence caused by the mismatch. The gains from the porting of the intake manifold may not be seen at their full extent on the dyno without matching to the heads.

Agree with this for sure, but some people (myself included) aren't willing to go the extra mile and port the heads, and so I'm just hoping for some decent gains with this alone.

For the ones that do port the heads...more power to you guys!

The difference in size between an unported, head without gasket matching and the ported/gasket matched intake ports is substantial. If the heads aren't going to be gasket matched, then the intake manifold shouldn't be gasket matched either.
I've looked at the ports of the intake manifold and there is plenty of power to be had without gasket matching. So, a nice port job with some reshaping and enlarging of the inside of the ports and work to the inlet is all you guys will need if your not doing the heads. I think you'll be impressed with the gains!

You can definitely take your current one off and send it in or you can do like I did and purchase a new one through GM then send it in. Mine is actually going to be up for sale as soon as I get the porting back. Thanks as always

Not necessarily. It all depend what is your ultimate goal and what are you trying to get out of. The guys that I am currently working with I believe will offer different stages of porting. From aggressive to mild. I chose to go full out with tune. Once I get the porting back and do some datalogging along with dyno we should know where the tune will fit

I plan on doing the whole nine. The heads/exhaust/IM/Headers and even installing a manifold cooler from mace over at aussie. I agree with you that if there's no plans to do the heads then there's no need to gasket match. Like I stated earlier the big gain will come from doing a complete porting and tuned, but we will find out very very soon what the IM will net us which the majority peoples will probably end up going with

Getting tuned by Trifecta right?

Good point, wasn't sure if you were going to have it done locally.

Sure, matching the heads to the manifold is a good Idea but I felt a decent gain with just gasket matching the manifold.
Now that I've matched the heads to the gasket also it seems to have moved the power higher in the rev range. Where it would pull really good from about 4-6 thou with a peak at about 5500 and then drop off to redline it now feels as if it pulls all the way to redline without hitting a peak.

Sorry about the lack of hard dyno #'s but I'm just a poor guy who has an addiction.

I was asked about the tools that I had used so I'll post a few pics.

the inside of the ports are kind of hard to reach without cutting the manifold in half and welding back together.
I didn't have any loss or detriment by gasket matching.

Looks like something you would see during a colonostimy!!!

[KMPrenger]

So you said it seems the power has moved higher in the RPM range. It sounds like your saying the power comes on just as early as before, but pulls even longer (good!)....OR...are you saying it seems you have to be higher in the rpms to get good power?
