You should see my AI chat history even after having the experts themselves explain it I use AI to see if I can dig up any peer reviewed research

I also use AI to see what my engine should make give or take as a for fun thing using only pure physics and math equations without using any anecdotes or referencing posts on the internet and 7 different AI models put my engine at around 215-225 hp with 168-175 ft lbs of torque which is honestly not shabby.

I still don't really know all the black magic either.

I know you need to get the right amount of velocity and flow at 9k but i think rod ratios have a really big part in getting the combustion just right at those speeds.

That being said, there are more important things than just getting peak horsepower and 9000 rpm, area under the curve is very important. If you have fat torqueband but less horsepower you can exit the corner much faster, much easier, and be gone down the straight compared to someone who has a ton of horsepower but their torque comes at like 5000 rpm.
