Although octane rating may affect stoich it cant be simplified as a percentage of octane (iso-octane) as he assumes For example Methanol has a RON of 113 octane but has a stoich of @6 5:1 and Ethanol has a RON of 116 octane and has a stoich of @9:1 Both these fuels have alot more oxygen in them hence the lower stoic values
- Need help from Boise, ID area high octane buyers
Generally, they will sell high octane at the raceway Also do you have fuel oil distributor in your area like 76, or up they are called Sharp Oil, Wright tire and oil, ect If worse comes to worse and you cant find any go to the airport down to general avaiation and get some AV Gas
- Methanol octane rating | DSMtuners. com
While octane measurements of alcohol fuels put octane between 100 - 110, the actual octane is much higher due to the higher cooling properties If you don't believe me, remember this: Running straight methanol (I know you're talking about meth injection) will cool your intake charge so much that you can run without an intercooler
- Best octane in anchorage? - NASIOC
Lower octane will cause the engine to 'ping', or detonate under higher load sections of timing curves With this 'ping' comes an audible sound that the ECU will pickup via a knock sensor The ECU will remove timing (read; power) from that section of the timing table and the car should drive per normal
- How much octane does methanol injection really add?
The problem I have with that calculation is that it seems to decrease the effective octane of the original gas, which makes no sense Furthermore, the octane properties of methanol should come from mass-flow, not the converted flow When I try to do anything like that though, I end up with a total octane value of 110+ which makes even less sense
- Using lower percentages of ethanol. . . (E20,E30,E50)
The problems with the race gas calculators is your going by octane numbers E30 is estimated 93-95 octane IMO it will suppress knock better than it's equivalent 93-95 octane std petrol fuels Same with E85's 105 "rating" If your going to play with blends I think it would be a good idea to get an ethanol percentage meter on the return line
- running the stage 1 91 octane map with 93 octane fuel? - NASIOC
Yes, you can most certainly run the 91 or 91ACN map with 93 octane fuel The 91ACN and 91 octane maps are just more conservative maps so you will gain an extra margin of knock resistance as a result if using them with 93 octane gas It certainly isn't required, but some of our customer like to be more on the conservative side of things Bill
- Why not 93 octane in the west? - DSMtuners. com
If you make 93-octane premium instead, you use up less of the high-octane stocks, allowing you to make a higher proportion of premium fuel In the Midwest, where an extensive customer base of good old boys in pickup trucks consume vast quantities of 87 octane, demand for premium fuel is low enough to make genuine high-octane premium
