ClaudeMachining Posted August 3, 2017 Report Share Posted August 3, 2017 Race fuel is clean, lead add lubrification, that's ok. But if i use c16 on a full stock shee, without playing with anything , it will run as good as 91??

ginger Posted August 3, 2017 Report Share Posted August 3, 2017 i think it rill run as good. but wont run any better or show much improvement for the cost. 1 Quote Link to comment Share on other sites More sharing options...

Or would it be nonsense? I have avoided the alcohol due to the PITA it can be to start in 30* and below temps when ice racing. But I'm hoping to get back in to racing clay again in the warmer months. So, thinking about doing alky on at least one of the new bikes. Quote Link to comment Share on other sites More sharing options...
ginger Posted August 4, 2017 Report Share Posted August 4, 2017 Alky is already oxygenated to a degree. thats why it soaks up moisture so fast. Quote Link to comment Share on other sites More sharing options...
ClaudeMachining Posted August 4, 2017 Report Share Posted August 4, 2017 But yes, i know some stuff about fuel. I used lots of different fuels(pump, diesel, nitromethane, alcool, 100LL, Jet-A, propane) for different type of engine in my life, but i didnt play munch with 'race' gas. Plus i know quite a about all the theory around that subject. Envoyé de mon SM-G935W8 en utilisant Tapatalk Quote Link to comment Share on other sites More sharing options...

JTmachining Posted August 4, 2017 Report Share Posted August 4, 2017 When it comes to fuels there are some things you need to know. Octane (RON, MON, AKI) numbers. This number lets you know high of a compression ratio you can run. It also lets you know how sensitive the fuel is (difference in RON and MON) to dome design. Higher compression ratio means more efficient engine. BTU. BTU is the stored energy of the fuel. More stored energy means ability for more kinetic energy. Look at the lower heating value. Pure gasoline is around 116K BTU/gal. Ethanol is around 76K BTU/gal, Methanol is around 57K BTU/gal. Oxygenated percentage. More oxygen in the fuel, means you need more fuel. See Stoichometric ratio Stoichiometric ratio. This is the perfect ratio of fuel to air. For a gas motor, this number is 14.7. For Methanol, this can be around 7. This is a start for jetting. Most run the engines richer under load. Oxygen in the fuel will effect this number For example. 93 AKI fuel, no ethanol, no oxygen vs 93 AKI fuel, E20, no oxygen. The first one will make more power as the E30 has a lower BTU rating. JFC Quote Link to comment Share on other sites More sharing options...
