    Alright this is concerning stepping up injector voltage in order to run saturated injectors in peak-and-hold "mode".

    Run down of the setup:
    -Megasquirt-III/MS3X(when it comes out), or Vi-PEC if they support Flex Fuel in time
    -E85/Flex fuel
    -ITB; Staged injection; 290cc/410cc Denso Injectors(CBR/RDX) running around 60psi.
    -Dry nitrous fuel comp. through primary injectors; on only when secondaries are fully online.

    And, my itemized questions:
    -I'm thinking, would it be safe to run sat. injectors at around 60v?
    -I know this will caused increased heat; but would the heat generated be easily dissipated by the fuel and could the heated fuel be beneficial(ie: the "200mpg carburetor" theory)?
    -Also, would it be beneficial to run the injectors in PnH mode; increasing response time?
    -Would this help out as far as the staged injection goes(even though there's blending, maybe reduced lag-time between switching)?
    -What about running the primaries(290cc) injectors at a lower voltage(~24v) to reduce heat since they don't see as much fuel flow/duty?
    -Can the transistors in typical PnH circuit handle the voltage and current(2N6044, LM1949 controller)? Should I upgrade?

    Edit: Can a mod please add "Injector V mod" at the beginning of the title? Thanks
