I was talking with a Pro Mod friend that is getting ready to get his feet wet with this new car. He runs alcohol (methanol) with Enderle injection. They set the system up to run lean at the start and richen with each gear change. Most likely because of the lack of intercooling and the increase of engine load with each gear change. Their target a/f on the top end is 4.0 to one. That's with a mag. Hope this helps you.
Some other tips I got from the conversation with him.
Engine configuration: BBC based (wedge head)
Static CR: 11.5 to one
Ignition timing on the top end: 32 btdc
His max boost target, at this point, is 38 psi. He's starting out with 32 psi. He's running a slipper clutch so it's hard to start out with a smaller tuneup. It takes HP to make his combo work so they can start getting good data to work with for future changes.
When I say they run lean at the start, there is a fine line. They run lean enough for as close as possible to best lean power, but if they go too lean while the slipper clutch is slipping toward full engagement, they can get into an imbalance between the tune up and the clutch which unsettles the tires and causes tire shake.
