I’m thinking a Hell Yeah on this one! Treatin launch like having a 8 1/4 rear

crank runner over-er
Massive vacuum leak on a throttle shaft. First pass it fell flat on its face. 8.4 at 110.
Second pass I babied it out of the hole, slowly rolled into it and short shifted it. 7.1 at 112.
Didn’t break it so I can’t complain too much.

The 112 pass it felt SLOW. I’m going to be overly critical of how it ran, but it’ll get sorted eventually.

Wow, that seriously is a hot back half!
I was pretty happy with this, I’m that Patterson fella.

You should be happy with it. It hauled *** and didn’t break. AND the engine was in pieces on your garage floor 3 days ago.
Congrats. Good to hear it held together and ran hard

The difference between your car making a clean pass (my brother) and your car falling on its face and going a 3.2 60’
I’ll just say I’m happy I wasn’t recording in the car

After some much needed sleep and some time for reflection. I had a killer time with my friends and family. Crazy to run 131 to the 1000’ on the street and not be bothered only to be a nervous wreck in the lanes. Cant wait for the next track day, next time I’m going with zero expectations. Check the A/F on the return road photo. Big yikes.
Just know that combustion makes the most heat at stoic (14.7:1 for regular gasoline). Ask any small aircraft pilot, combustion temps get cooler the further you get from stoic -- in either direction. The reason for going rich under heavy load is to both cool combustion, and to better facilitate spark ignition under extreme pressure. You can cool combustion just fine at 16.82:1 AFR so long is it doesn't induce ignition misfires. Be scared at 14.5:1, be very scared!

I was nervous also and have no idea why. All the dumb crap we do and making a pass at Pomona was nerve racking. I don’t get it. After the first one though the nerves went away and it was game on.
Don’t fret the afr on light load, that’s in the carb tune up and right where it needs to be. You’ll get good mileage and like @mpgmike said above it’ll run fine there as long as it’s not misfiring.
