Wondering if I could pick some of your minds here. I have an Alky injection system setup on my 2.8H Kenne Bell. These injection systems usually are used on turbo cars like the Grand National. On my car, it serves as an octane booster to run 20 psi of boost (was 22-25 psi).
Questions: What MAF voltage would be considered the norm for activation for a twin screw car? I have heard 3.0 - 3.5. Should it come on hard or gradual?
My system has three controls.
1. Turn on - uses MAF voltage to determine when to activate the system.
2. Initial - sets the ramp of the slope. You can have it come on slowly and finish strong, or you can have it come on strong and stay strong. I would think the turbo cars want a more gradual spray. You would think twin screw cars need to come on hard.
3. Overall voltage - effects the entire slope and multiplies all voltages on the slope.
Problem is not many people use an Alky injection setup on a twin screw. It's easier to just pour Torco in the gas tank. If setup correctly, the Alky system would work just as well or better. Problem I have been running into is the Alky system activates too early and before WOT. This bogs the motor, as the narrowband is trying to keep the A/F at 14.7 and can't compensate for a large amount of fuel being injected.
Need to figure out what MAF voltage to activate the system and what slope to spray at. The amount of spray is subjective and depends on how much boost and timing you want to run.
