Hi all,
I want to know the engine performance curves for Honda CBR600 f4i/RR, Yamaha R6, Suzuki GSXR 600 so that i can decide on the engine. I tried my best top find the info in google and forum, but in vain.

Slim, a posted request like that fits you right in with the barrage of basic questions we were getting here a year or so ago. You should know better.
Firstly, I doubt you can get this data anywhere in a form where it can be realistically compared.
Secondly, the curves from the engine on unrestricted intake and a road legal exhaust system are highly unlikely to match anything you will have in a FSAE car.
Engines are chosen for all sorts of reasons, some not so obvious (like the better US teams occasionally being given free engines, so the results show that engine in a good light).
A far more pragmatic approach would be to do the rounds of the bike wreckers and find something you can live with and incorporate it into your design.

To be honest there isnt much difference between the engines you listed in restricted form. A better comparison would be between the 450 single, 550 twin and 600 four cylinders.

At least something to discuss about...However, with the restriction there isn`t a noticeable difference between the engines. Personally i would look at the packaging of the engine if i could choose between Honda, Yamaha, Suzuki.

Let`s discuss it
