The amount of oxygen in the air is consistent, even at altitude.

It is the partial pressure that changes, thus the molecules are denser/closer together, which provides for greater explosion/expansion upon ignition of the fuel/air mixture.

Are we splitting hairs here? If the molecules are more dense, wouldn't they "take up less space", which means more of them would fit in a certain space. Which means that area would likely have more oxygen?

So is it safe to say that 91 octane in 32F weather outputs similar results as 93 octane in 77F weather? And if this is the case, would methanol be useful in conditions like 32F or lower (0c) when running no more than 17 psi max?

Speaking of meth, i re-enabled my setup this morning. I set my gauges to autotune boost/IC set at UT60 IC20 (real conservative for meth) and needless to say, watching the IC flatline after 2 short 3rd gear pulls ensures it was working properly!

Meth ftw.

I got on it on the way to work today. Car pulls HARD, 3rd gear spun to like 80ish 3-4 at 100, 4th gear pinned me in my seat and I was getting thrown around the lane a bit, not spinning or anything, just that sensation of fwd tq steer for some reason. Checked my settings and loled

Boost Limit 17psi
Autotuned boost 16.8psi
Ignition Correction 0
Aggression level 0.2 LOL

Car feels great in the 18 degree weather.

I got the same fwd tq steer feeling too, pulls so hard in the weather. It breaks sideways in 2nd without meth and the tires are and inch wider in the rear. I am set up to race a supercharged s2k this weekend, how do you think I will do from a 60-130 run?

I did a few runs myself last night in 35F and IC flatted out to 5 the whole ride home on 93 octane with no meth. Thus I asked that question.
