As far as race gas, I believe there's a place out in sparks that sells 100. But unless you're like Kevin who will have a race gas ECU map that you can easily switch over to, you'll need to run it 24/7 so the ECU will adapt to it. That's expensive... pretty much plan on doubling your monthly gas expenses... and I'm still not sure you'd notice a lot of power. |
Yeah I could retard the timing a little, I don't really want to though since it's already set at the stock 10* BTDC. I'll have to play with it in the next few months as the temperature heats up at events. I'm thinking about getting an adjustable fuel pressure regulator to have a little extra tuning tool.
I'm not sure if you were talking to me or the other WRX guys with that last part... my ECU doesn't adapt to anything.
If I use higher octane it'll be pretty easy, just run the tank down to 2 or 3 gallons before an event, mix in an equal amount of 100 oct., and I've got 95-96 insta-octane for the race. The Monument auto parts store here in Livermore sells the Union-76 "Cool-Blue" 100 octane race gas.
