NOPI Phoenix

[sbiggi]

Well my car made it.

I drove it from Denver Colorado all the way down and back, 900 miles each way and 12 and half hours.
The car had absolutley no problems aside from some light knock that came and went with the elevation change (6200ft down to 1243ft)

So we get down in to Phoenix around 7:30 pm on Friday.
I decide to do a couple pulls on the highway to check my A/F. I get tons of knock. A/F is low 10s. This is the exact same tune I have in Denver with no knock. O wait, I know why 91 octane at 1200 feet above sea level

So I put in the race gas in the hotel parking lot, and change over to my race tune. We take it back out on the highway. I do a 1st through 3rd pull and the coupler on the charge side of the intercooler pops off. So I fix that and head back to the hotel, because its late and I want a beer now.

Saturday, get to the track, get teched and then wait. Finaly first open session come at 1:55, over an hour behind schedule already. I run a 12.593 @ 112.07 with a 1.764 60' :Yawn: Slower then in Denver but 1 mph faster.

First round Qualifying at 3:25pm.
I get the best launch ever. 1.558 60' on All seasons. I'm .3 faster at 330' then pssshhhhh. Blew off the coupler again.

Then everybody started puking car parts on the track and we had to wait for ever for them to clean it up, and fix issues with the timing lights. The track got cold and my 60' got worse.
Second round I ran [email protected] with a 1.828 60' qualifying 4th.
Third round I ran a [email protected] with a 1.951 60' qualifying 3rd in Power Street.

Sunday...... it rained. I guess it dried up enough around 4pm for the few people who stuck it out to do a little racing, but by that time I was 300 miles away on my way home.

So the car could run a 12.0 or a 11 with a good launch, and easily if I fixed 2nd gear. O well. Had fun anyways.

Cliff notes:
Car was not much faster at 1200' compared to 6000'.
Ran my best 60' of 1.558 on all season tires.
Qualified 3rd in PowerStreet


Thanks for reading!

Really nice 60' Seth. Did you log the car at all for data comparisons at higher elevation? How was the drive? I've been thinking of taking a trip back to CA going that way, since I've already come through Salt Lake (HWY 80).

I didnt get to do a log on race gas.
Things I did notice.... idled around 14 inHg instead of 11.
Decel it would pull 21 inHg instead of 15

The elevation change messed up my pump gas tune though. Phoenix only has 91 octane even though they are ~2200'. My 91 octane tune had to much timing for down there and was knocking really bad.

The drive was incredibly boring. The only thing that kept us awake was the advertisements for the reservation trincket shops. Lots of nothing for the most part.

Whats with the shitty vacuum?

I live at 6200' elevation. Thats usually 2-3psi less absolute pressure up here, so the engine pulls less vacuum.

Dayyyum...that's a nasty sixty on all seasons.

Nice work.
