I know f*ck all about this... But I've read here and there that running gas results in slightly lower performance figures. But I've also read that gas has a higher octane rating than petrol - 108 or there abouts?
Can someone set me straight here? I've googled a bit but the results have mainly been about diesel propane injection, or the usual LPG conversion sites, then I gave up... If the octane rating is higher, how come the performance figures are lower? Is a stock LPG conversion(?) putting 'less' gas in than it would petrol? If that's the case can you wind the mixture/boost up to compensate? Does LPG give a charge cool effect? etc.?
