A couple of random notes from my engine:

- I've used OS P3/P4s and O'Donnell 97Ts successfully. I had the widest tuning window with the P3, the best fuel economy from the P4 and the most durability with the 97T

- I've come to fully expect at least 7.5 minutes a tank in races. Recently I went 8 minutes 45 seconds on a tank because I got called in early on my last pit stop, but still finished the race without backing off on the last tank at all

- My engine doesn't start to make power until it's at 250 degrees. It's really happy once the temps get up to around 270 degrees. Don't let the temp gun scare you - if you see a little smoke down the straightaway, you're fine. These engines just run hot.

- One way I've started to tune the LSN recently is to get the HSN where I want it, make sure then engine's fully warmed up, then run a 20-30 foot section of the track at 1/8-1/4 throttle (like a slow rumble strip section), then stab the throttle and see how much smoke I get. If it really belches smoke, I lean the LSN 3 hours and try it again. If I get very little smoke, then I fatten the LSN up 2 hours. I don't have a way to describe exactly how much smoke I'm looking for, but just making sure I get a little more than I'd see while ripping down the straight, but not fogging for mosquitos either.

- After one of my recent qualifiers, I drove up pit lane lazily, and just parked the car since no one was there at the time to put it on the wall. I walked casually down the driver's stand, and stopped to talk to someone on the way to pit lane for about 90 seconds. I then walked casually over to pit lane, and noticed someone had put my car on the wall. When I got to the car, it was still idling. I hadn't touched the throttle in about 2 minutes. I'm pretty sure that's about as good as an idle gets. I wasn't lean bogging during the qualifier, either.
