So all by itself its a guaranteed hp increase over an LS1 manifold, just need a decent set of heads to bolt onto it as well. I might have to look into that, what TB mounts up to it?

I have had no issues with heat soak either. The hottest my IATs have been since install was 112 degress. I have a OMEGA THERMISTER Sensor and it helps to lower IATs faster then the stocker The engine management system on the 05-06 GTOs are designed to start pulling timing when the IATs hit above 115 degrees or so. All in All, no problems with this intake. Good Fit and finish with a HP gain as a bonus. Very nice S.O.T.P feel when compared to my stock set up.

I replaced the stocker that was on my LS2. 05 GTO. I purchased it because of the extra strength and good looks & I also knew I would gain some HP. I am very happy with this intake. It is down on HP by a few when compared to a FAST product but to me the added strength and good looks including fuel rails was worth the $500.00.

Finally some real data! I too am interested in this product but I have couple of extra questions.
What mods did you have on your car prior and after the change to the Typhoon? and
Do the intake runners line up with the head intake ports perfectly or would you need to match port the intake to make the runners and ports line up perfectly?
Thanks!

Thanks to our customers.... Thanks to all of you who have actually used our products and are happy with your Typhoon manifold and in some cases our Power throttle bodies.
We did have some issues with the Typhoon Manifold for LSx installations when it was first released. All of these issues were related to some of the parts in the kit, not the manifold itself. The only manifold related issue was the interference with the bolt heads holding the valley cover on. How this came about is the engine that we primarily designed this manifold around had AFR heads on it. The AFR heads actually position the manifold about an 1/8" higher than on a stock engine so we didn't realize that we had a problem until some of you pointed it out.
This can be fixed by switching out the bolts to some with thinner heads. We have since changed the design of the manifold to remedy this problem. However, on some of the models of this manifold, we had quite a few in inventory and so even manifolds sold recently still can have minor interference with those bolts.
While some of you may not trust dyno figures released by the manufacturer, my policy is if we don't get the figures we want, we don't publish them. If a manifold does produce good numbers, we do publish them. We currently have a number of engine dyno tests posted on our web site (www.professional-products.com) and one of these tests was done at the request of forum members. We tested our manifold against an LS6 manifold with no other changes. I don't recall the exact figures but I think we picked up 17 hp at 6,300 rpm which we were pretty happy with.
Keep in mind that results can vary from one engine combination to another. Yes, we got 17 additional hp with the engine combo we had. We had AFR heads, a modified cam, long tube headers and a modified computer. If you swapped our manifold for an LS6 on an otherwise stock engine, you might not get the same result.
Again, thanks to all of you who had positive comments about our Typhoon manifold. We appreciate your support.

I love my PP manifold. Not a single problem at all. I did a lot of reading and read all the issues people had. Mainly missing parts that were needed for install. When I recieved my manifold i went through everything to make sure I have all i needed to install and all parts that people had previously mention to be missing, they were all there. I havent had a dyno yet but I will soon. I have the 85mm version. I specificly got a baseline tune right before this install so i can have a direct back to back comparisson between the 85mm and a stock ls1 intake and I got this intake because of my nitrous addition.

i had the polished 85mm and it was great...and since the bottom opens up it makes it very easy to port and clean up. by just cleaning up the casting flaws on the inside i felt a very nice difference. for the money i think its certainly a great option, and it looks great aswell.

Ok I'll Get One just to be a Tester. Just because I'm interested in a few extra ponies and still have a stock LS1 intake and I HATE people who haven't tried crap themselves putting others down I'm going to do this:
1) This week I'l get a new polished 85mm intake and TB to put on my WS6
2) I'll take to a pro installer here in San Antonio that I trust for install
3) We will dyno before install, after install and then after a tune.
4) I will ask Danny after the install to tell me any snags a pro like him could come across during the install and ANY modifications that have to be made.
5) I will post results here and in a new thread as well.
Any dealers on the list wanna help me out price wise to settle an argument? Hint Hint..
Heres' my current setup before install.
Stock block bored 20 over 10.5 compression
224/224 581/581 114LSA cam
Mild hand port on heads 5 angle valve job
SLP tuned length ceramic coated headers
Custom Duals with X pipe into Magnaflow 4 round mufflers sans cats
Custom built 4l60E with yank 3200 converter.
Keeping in mind that I am totally unbiased, let's see how it goes! I may keep it and love it, I may call it crap and get something else. I love playing Devil's advocate!

While I'm at it! While I'm at it. After the tune, I'll take it out and get it hot so we can address the "heat soak" issue and go back and dyno it again after about 20 minutes at full temp. I'm betting the difference is only about 1-2 hp.
But let's see, it may be great; it may suck.

Sorry guys! I have the Manifold and TB, but because of a work situation haven't been able to get away to go have the work done. But my coworker is supposed to be back in a couple of days to help relieve me and I wont have to be putting twelve hours a day in, and can get it done. I am looking forward to it.
