I just got a desktop dyno program where you can enter the specs of your car and it will give you a horsepower estimate. It's really neat, but the help file doesn't work so I'm going to ask some questions and see what kind of answers I can get from all of you.
Manifold type. Which is most like the split port 3.8 intake system?
Single-Plane manifold
Dule-Plane manifold
Tunnel-Ram manifold
Individual Runner (I.R.)
Tuned Port Injection
Sequential Fire Injection
Also does anyone know the average flow rate in CFM of a gasket matched set of intakes?
One last thing, and I'm going to assume that RGR might know this. It's asking for the flow rate like this: 300CFM @ 1.5inHg or 300CFM @ 3inHg.
I have no clue what that last part is. Any help?

WHO NEED GOOGLE WHEN YOU HAVE BROTHER COREY!!!!
HG is the periodic symbol of Mercury or the Hectogram
But in the question "300CFM @ 1.5inHg or 300CFM @ 3inHg." = 300CFM @ 1.5 inches of mercury or 3000CFM @ 3 inches of mercury when using a tool called a hydrometer to check the amount of vacuum the T/B, Carburator or other type of device that is pulling in air. It is a simple way of scaling airflow using vacuum.
And in my opinion a Splitport would be most likely be closest to a I.R. Individual Runner. But with a twist in that you have 2 different lengths of runners per cylinder.

if you do the single plane runners, you get the closest results. I used to have that program

Thank you, to both Monkey and Brother Corey. Thanks a lot. Now all I need to know is the average flow numbers of a ported intake set.

I realize it's not going to give me an 100% accurate number, but I'm just curious. That and if I can get the right baseline there, I can change things, like bore and stroke to see what gains might be possible.

Here the stock flow numbers for a 99+ car and the cam specs too. I tried them in my desktop dyno also, and I was getting something like 160hp and 260tq. Let me know what you put down for your data and the numbers you got.
Lift INT EXH
.100 65 51
.200 122 100
.300 169 127
.400 199 139
.500 209 145
.550 216 145
Cam: 178int/194exh (@ .050" lift) .427/.446 lift, 116 Lobe sep, 111 intake c/l
