347 - that toluene surely is good stuff, but I like the idea of being able to just pull up at a servo, and fill up. At the track, I think I'll keep using Avgas because it was tuned on the dyno in this configuration. All the engine builders up here are talking about a 102 fuel that's coming. I know that there's a company that will sell you 114 octane unleaded, but it's around $7- per litre.... The 102 is suppsoed to be available at the pumps ?!?
Andy, I haven't tried Mobil. I might give it a go, for a laugh! How's the XR8 going? I suppsoe the new addition means the Vortech might be a little way off
Adrian, very interesting - thanks a lot! "BP is more of a green, environmental type fuel".... ****, I've been using that for the last month, and I want to save my pistons and head gaskets from detonation before I want to save the environment!
I just don't know how to separate the sales BS from tech comments..... A special volatility profile means the fuel burns more smoothly in the combustion chamber...
Is that not how "octane" ratings are calculated? Going to other extremes, Nitromethane effectively explodes in the combustion chamber, and is highly volatile. This makes the power. Wouldn't a lower volatility therefore make less power?
Sorry, just me overanalysing things again....
