Back here again, diverted myself with a paint and interior fix-up thread, Spiffing-Up the Rig and a cooling thread. Blown & Ventilated.........................
My latest thoughts on supercharging, daily driving, mileage/gas prices....................How much boost?
I have a 4 1/8" pulley on now pushing about 4.7lbs. I am running low grade fuel with Lucas octane boost. I am after some savings by running a lower grade fuel, lower boost and keeping it out of boost. It runs in closed loop more which keeps it at 14.7:1. It gets much richer under boost in open loop fuel. I need a bit more time with it but have added timing and decreased fuel for this decrease in boost. If I keep my foot out of it and can keep it in open loop fuel most of the time, I should see some improvement in mileage.
If I only get nominal results in better mileage, I will likely go to the 3 1/2" pulley and 7.6lbs at 5,500' elevation (8lbs at sea level).
With this testing, I will decide on which pulleys to keep and may purchase another size.........................I'll report back on this. It will help me determine if I want additional pulley sizes. I think maximum, with this build, is around 9lbs without more octane or cooling. I am not going to intercool nor add meth injection.
