Can someone explain me why these GT3s produce less HP than the amount mentioned by the manufacturer (in the video on the first page - 443.7 and after the installation of the exhaust 474.6)? I understand that this engine has no turbo and the weather also has effect on the dyno numbers, but is the difference really that big? I have been looking for such information for a long time and I will be glad if someone tells a bit more.

So, 443.7 is the power at the wheels? If you convert that into HP at the crank it becomes somewhere around 520-525 bhp stock? Please correct me if I am wrong, because this is confusing to me.

I raced an identical car w full Akra race system and there was no difference in speed. However, I could tell my throttle was responding sharper on the stock car.

So if you're saying you don't believe in the quoted hp gain with the Akra system, this is surprising news. Can you add anything else to this?
