Also what is the intercooler's HP rating, for future mods reference??

Thanks

Did a little research on octane ratings and have found that over in the US, you use a different octane rating system [Anti-Knock Index (AKI)] where as pretty much the rest of the world uses [Research Octane Number (RON)].

So the fuel here is not as great as I thought.

The standard is 95 RON = 91 AKI
The premium is 98 RON = 94 AKI


loads of info on Octane rating on wiki
