Of the multiple I've tried, I find solidworks (for CAD) with HSMWorks add-in (for CAM) to be the easiest/most intuitive. Plus the interactive help menu with HSMWorks is seriously thorough. I had basically zero CAM background (manual G coding 2D shapes in wax in college 20 years ago) and was able to post to a HAAS VF-3 and make my intake parts without scraping anything, doing each tutorial and following the help menus when needed. I did have some pointers on how to turn on the machine from the 'machinists', but I got the feeds/speeds right from the back of the Garr tooling catalog.
Digitizing a port though...hmmmm that'd be tricky. Cut a port in half and use a laser of choice? Or...
We have a machine built for digitizing ports and chambers that we would be willing to sell for pennies. Cyclone 5 axis scanning machine. Think automated CMM but with 2 more axis that you manually set. Machine supposedly automatically moves in XYZ and picks up the point cloud, software creates the mesh for import into CAM. I've never used it.

How many pennies exactly? I would be willing to pay a few hundred pennies for it. I totally need more tools in my garage that I don't know how to use yet.
Probably in the 4 figures instead of the 6 that it was originally purchased in. There's no one here anymore that knows how to use it. It hasn't been used in the 11 years I've been here. It's on my to-do list to learn how it works so I can help draft up the classified ad.
After years of playing with various turbo cars I have come to the realization the shape of the torque curve is a prime indication of how well the overall package fits the application. Go too big with the turbo and the lower end has a big belly. Go to small and the top end drops like a rock. When everything (cams, turbo head etc) is sized properly the resulting torque curve looks more like a mound than a mountain peak. In other words this power curve is what I would be ideally looking for beyond just big HP numbers. Props for a well designed setup!
Is this an impressive result? I ask because my built in my garage bp, with a fm turbo kit made more power at 4,000 rpm, and peaked at 375 at 6400rpm and held it to 7400rpm where I decided that was enough at around 15psi of boost. I have the 6 speed in the car so I thought that was a good place to stop pushing the motor.
I realize all dynos are different. This just didn't strike me as thread starting impressive.
We'd need more details on your setup before determining that.
But also consider that this was a product of bolting a turbo capable of over 450whp on a motor built for n/a track glory. Obviously it's not going to look the same.
To that end, you wouldn't rev your motor to 9000rpm, either.

I wouldnt rev any BP to 9k. Really wouldnt rev to 8.5k again like I was before, that was silly.
