Installed Ported intake manifold
Just got done installing a intake manifold that was ported by Cory at LS2 Port Works. The job was pretty straight forward. Just took it for a test drive. First thing I noticed is that the throttle response is instantly quicker. The car also reved quicker too. I will have more results as soon as I take it to the track. The car is currently running 12.1 @ 118 and I am trying to squeek it into the 11's. Hopefully this will shave off a few 1/100ths or even a 1/10th.

But, the midrange gains are what is so impressive. Here is my graph.
You can't go wrong with Cory Harris or Spin ported FAST. Both are very reputable!
BTW: Mikeg, sorry for kinda getting offtopic, I think you will get close to getting the 11s! From my ported Fast I dropped about .2-.3 on average in the 1/4 (And that was on street tires).
Here is the graph:

In addition to what's been mentioned, you'll also notice much less (if any) heat-soak compared to the stocker.

Typical porting gains can be anywhere from 0-10hp on average. Buy a FAST and get it ported. Typical non-ported Fast gains over ported stock is 15/20... and more coming from the porting of the fast (And of course more substantial gains on H/C cars). I personally gained 17/20 with my Ported FAST 92 over my Ported Stock on a bolt-on only car. Also, notice how it was 103 degrees out when the dyno of the Ported FAST was done! I think it has a little more in it with colder weather.

Since you are going with a Cam in the future... a FAST would work very well with your setup. Typically, you will see more gains from the FAST with Cam and/or Head/Cam setups.

It took me about an hour. I'm sure I could do it much faster the second time around, buy I took my time to make sure I did not miss anything and I also cleaned everything when I put it all back together.
I wanted to do the FAST however funds are limited right now. I figured this was a cheap mod to get some power. After I take it to the track I plan on doing the Vmax throttle body. Then compare the 1/4 mile times.

No, at least not yet. The manifold for the LS7 is actually pretty good and can be ported with impressive results.
Many C6 owners w/ the LS2 engine feel the intake manifold is poorly built and not worth porting, hence the interest in the F.A.S.T and the Weiand.
There is not a F.A.S.T for the LS3 either.

If one can afford it a PORTED FAST can get you another 15 + rwhp over
the PORTED OEM. No question about it the FAST 90/92 will cost about 3
times as much also. The FAST is my favorite mod and with 4.10 I created an uncontrolable animal
BTW I have a ported oem in my garage. I may sell it with my diablo PREDATOR. U7194.

Ok, I just got back from Firebird Raceway in Phoenix last night. It was crazy busy due to the funny cars running so we only got to run in between them. I was only able to make one pass in 3 hours! I ran a 12.020 @ 120.55mph. This was almost 2/10ths and 2 mph better than my previous best. So I can definately say that the ported intake from Cory Harris definately helped and is definately worth the money. I know that a ported FAST is probably better but I just cant afford it right now. I know I can hit 11.xx as I spun pretty bad going into second. Next time I am going to put on the DR's and try to get that 11.xx.
The temp was about 67degrees at 1243 feet
R/T .333
60' 1.92
330 5.242
1/8 7.875
1000 10.130
1/4 12.020
mph 120.55

Gears. I can get wheelspin in the first three gears in the street. Its simply awsome with that combo. I have yet to try the 1/4 mile and I have plans to do that on nov 8th at CECIL in MD. I need a test and tune day.If I can get into the11's the first time out Ill be happy with that.

A test & tune day
If you can turn 12.02 you wont even need the FAST to get into the 11's. Just a little seat time . If you are crossing over at 120 MPH + the power is already There. I have a BOLTON W PORTED FAST AND 4.10

One time when swapping a ported stocker for a stocker, I timed myself from the moment I popped the hood to the moment I closed the hood....55minutes. Taking your time, it would be about 1 1/2 hours to 2 hours. Its a good DIY project and Cory's manifolds are awesome.

The reason I'm asking is that I'm curious if you know how much of a gain at the track just the intake manifold gave you.
Thanks in advance,
Christopher
