garethr Posted April 20, 2010 Share Posted April 20, 2010 For the purposes of this thread, only 95 octane is available, and octane boosters are banned. So... VVTi TT auto, decat or "sports cat", 95 octane, and a piggyback (AEM F/IC?). What would the limit be? Stock boost? Not even stock boost? A bit more than stock? 1 Bar? Nobody knows until someone tries it? Quote Link to comment Share on other sites More sharing options...
Pudsey Posted April 20, 2010 Share Posted April 20, 2010 A VVT-i has a Knock sensor, so it will continual adjust the the ignition timing. Obviously if you push it so far outside of its limits then it will go bang eventually, your always best running higher octane. That's if the petrol suppliers aren't just ripping us off of course, who would know if it wasn't 97 or 98 ron. Quote Link to comment Share on other sites More sharing options...
