C16 Race fuel and Avgas Question?

[akira]

Can anyone help me understand how these fuels work.

Are they able to run through a standard fuel system?

Can I adjust timing through programmable ECU?

What modifications ( if any) are needed to run these fuels on the track?

avgas can be run as a normal fuel, there arent alot of advantages except u may be able to run a little more boost. The c16 is a totally different game, as it is a very light fuel with a much higher liquid to gas exchange rate this means you need alot more to fill the combustion chamber and very quickly. Your standard fuel system will not cope you will firstly need to up the injectors so the fuel can flow faster, up the pump or at least regulate the pressure. You will also need to make drastic ignition timing changes which can not be applied to any other fuels you will need to run alot more advance as the fuel burns different to normal fuel, i can check with my dad the exaact principles behind it all as he has played around with methonol motors before. Best idea for a quick fix is avgas with 25% toulene (methylbenzyne i think, maybe??). Hope this little bit helps tell me if u need more info i can definately help you out!!

Avgas is now illegal even for motorsport all the rally cars are now moving to 98 octane unleaded pump fuel.

Apart from that AVGAS will stuff your cat in no time at all. I've heard it can also damage the oxygen sensor.

It is chock full of lead. Even 100LL(low lead) has some thing like 4 times the lead the old Super had.

The EPA will fine you big-time if they find this stuff in your car. Just a warning.

get a dyno-tune and run it on BP Ultimate or similar.
