I kind of look at using race gas (any kind of boost to octane) at track days as a preventive measure -- to delay/defer/block detonation as the engine starts to get hot with the excessive use of sustained WOT conditions (rather than really providing any added horsepower). Is that magical thinking?
Yes, and no. You will see below.
Basically, yes. There are already temperature controls to reduce timing based on increased heat so if you started seeing negative corrections you would want to address the tune instead of the fuel.
Always adjust the tune to the fuel, never the other way around.
Exactly, as charge air temps raise timing is reduced. As coolant temperature rise, timing is reduced. As ambient air increases, wastegate duty cycle is reduced (boost). There are a ton of compensations.
Race gas will help, I'm not denying that you will make more power, but not as much as you would guess. Using it as preventative measures isn't a bad idea, but the ECU is really the start there.
Because I wouldn't have the first clue where to begin. Not to mention the cost. This way works great, and haven't had any kind of issues.
Gotcha, not a problem I was just curious. E-tuning is what I was referring to, shameless plug for myself I guess haha.
