The main jet would have to be too small, not too big, to milk the oil.
The explanation of Injected alky could go on for hours. Like I've posted in other threads, Bob Szabo (
www.racecarbook.com) has a FANTASTIC book (80.00) on Fuel Injection that newcomers and 'experts' alike will find tons of information useful.
It includes ALL of the calculations needed to properly tune an alky system.
Just an FYI, we can't say anything about any system without some very specific information.
1. CID
2. Compression (true compression, not what the piston mfgr tells you)
3. Fuel pump GPM @ 8000 Crank RPM (flowed, not something guessed from some dude on Ebay)
4. Nozzle Sizes
5. Main jet size
6. High Speed Jet size and pressure (if you run one)
7. Altitude
8. Humidity
9. Temperature
10. Barometric Pressure
All of this plays into a "safe" base tune up and is part of the big picture.
Without one piece of that info, you're not going to be able to get into the ballpark without a LOT of trial and error (and if with a blower, a lot of burned up parts).
Once you have that info, and your baseline, you can then use some simple data logging...buy a EGT with 2 probes, and move it around from pass to pass to find your hottest cylinder. You can then tune via EGT. Once you have the temperature range you want in the EGT, it's just as simple as plugging in the numbers to a weather station, and it'll tell you what jet to run, and if needed what nozzles to change to keep the same system pressure.
Hope this helps...
