Thanks Guys!
Yes, we have a oil heater on the car, but not on the dyno, so oil temp was not always optimal.
Nitro does lean things out. As we had limited time on the dyno, I was looking for 'safe, fat' tunes. When we get to the salt, we'll run the safe fat tune, and see how much it leans out at the 3 and 4 mile.
Now, I must confess- Sparky was right, and there is a little more to the story.
We tuned on the nitro a bit, and had a really, really strong run going- look at the numbers, before the head gasket between the 6 and 8 cyls started leaking!
This tune scares me, though, and it is truly my 'pocket card'- I'll only consider running it if we are a few MPH short of our goal.
As for how the car pulls to 6000, that is one of the reasons I have picked the gearing I have for El Mirage. We are running on a 185 minimum, and I really don't think we can get there. I really just want to shake down the car, see how it performs, and get the engine teched and sealed.
