I found a guy selling a 93 cheap. Would 91 be ok at around 4000 feet?

Should be fine, but I'm not liable for anything.

What would 91 be in Leadville? 10,000+ feet. I always though less oxygen would decrease power. and then you are buying 10percent or more ethanol(Corn) so you only get 90 percent of 91 octane and at altitude -I have my conspiracy theories but it is pretty certain we all get screwed by the oil industry
but olathe corn is badass

[Roland H]

octane rating is calculated after the corn is added to the fuel. By the way, you're getting screwed more by the farmers than the oil companies every time you fuel up with any ethanol added fuel. You're also contributing to the starvation of less fortunate people too. I'm not kidding.

A gallon of gas sold at sea level gains about 0.8 octane rating for every 1000 feet above sea level it is used due to lack of atmospheric pressure (assuming car is normally aspirated too).

This is why we can run 85 in engines designed for 87 without issue, the altitude and lack of air raise the effective octane rating of the gas regardless of its actual octane.

Video of my fastest lap, a 1:39.425. Traffic and a big slip-n-slide into T9... I think 38's were attainable.

What time was that? I flew over your house today. Was on the ground by 5:00. Threw my drogue chute and landed in the field just behind the first turn.

That's my favorite stretch of the road. Gotta be going down too. Going up is boring.

Nice! That's making me want to spend money that I shouldn't.

Hmm, I will call or email Mark and ask him directly to see what he says.

Yes. Works just about perfect with the 255/40-17 at MPH. If I was hitting the rev limiter at the end of the main straight, and coming into T8, it meant I was getting it right.

Looked like you were hitting the limiter a bit before the braking point...do you think the 3.15 would help at all?

Anyone know the correct order, if there is one, in which these washers and spacers go on the bolt for attaching the seat belt to the seat of a 4 door?
