D##n Belgian keyboard on this borrowed laptop! Still, I don't know the Renault engines, but if you are running a engine straight from the factory then of course you can get more power out of it. You will lose engine life and reliability but you can't have it all! Renault designed that engine to last 100k plus - race engines might only last 100 miles - power and engine life are often a direct compromise
 
Isn't there a Clio racing series? My first suggestion would certainly be to sniff around that scene. Not that they are going to give their secrets away...
 
USA does have bad gas (no pun intended).



When we go traveling to the USA with our Ford Windstar and fill up with regular un-leaded gas, the engine light turns on!



This never happens with the regular gas here in Canada.. So we end up filling with a grade higher in the USA, so the engine doesn't get damaged.
 
Faceman and some of the other folks, FYI US and Euro octane rating systems are different.



Basically we have 2 octane ratings: Motor Octane Number known as MON and Research Octane Number known as RON. Methods of testing are different and RON method is not indicative of the performance of the fuel under all conditions but it produces higher numbers and is often used for marketing purposes. RON rating is used in England and most of the Europe and was used in US years ago.



US adopted AKI (Anti Knock Index) which is the average of the RON and MON (R+M/2, take a look at the US pump next time you're here).



The closer the RON is to the MON, the more stable the fuel is and it is best if MON is not lower than 10 points below RON. This is very important in engines with compression ratios over 10:1.
