That is true, there is no replacement for displacement!!

So yes, given a v8, you can make more peak HP/trq

C4, you are correct, but you can make 4 cylinders fast!!! That is all that Im implying, and it sounds like you do not believe me.

I dont mean to act like an ass on the internet, but if you make 220whp on a motor, put that in a lighter car, and have really short gears, and BAM!!!!! You now have a fast car!!!

Just like with your bike, you made 167WHP, and how much does your bike weight. Its the same thing!!!!!!!

And if you do not see that, well there is nothing more I can say.
