I agree, you have to read and then do. And, you can’t just take everything you read and accept it. You have to test it and then do other things.
Thats why I flowed everything at as high a test pressure as I could. I flowed everything in reverse. I have tested probably 6, maybe 7 different 50 degree seats, probably 20 different 45’s and several 55’s. And I developed 3 or 4 (I forget if I actually had the 4th one made) seats that I couldn’t find, but only one actually worked and it has a very limited use.
Running a full set of tests on every seat is time consuming plus it generates huge amounts of data that you have to look through and analyze.
I spend more time looking at the data coming off the dyno than I do making pulls. Especially when looking at the fuel curve. And timing. Timing is a real PITA to do.
