    Default Setting up A0015 VE MULTIPLIER for a 2 stage dry shot

    OK im gonna put a 2 stage 350 hp dry nitrous kit on the car..

    stage 1- 3200-7000 rpm 175hp
    stage 2- 5200-7000 rpm 175 hp

    Right now im at 12.5 afr at WOT... and i want to be at 11.5 afr at WOT when the nitrous is on.

    so according to the math I need to add 10% to the VE the correction factor, set it 1.099 from 3200-5200 rpm's and from 5200-7000 rpm's I need to add another 10% for a total of 20% more to the VE multiplier table making it 1.199..

    should I round up to the nearest # or leave the correction factor as it comes out??

    is this correct??

    add more VE 20% total when the 2nd stage kicks in cause im spraying both shots at the same time..

    any thoughts??

    edit:

    I just saw the sheet that beer posted on the other thread and I was fairly close, it tells me that when both kits are on i should target for roughly 10.5 AFR... WOW lota fuel for a 350shot...

    its a good starting point

    Let me know how it works (the sheet), I made it a couple months ago and had Doc and a few others look it over, and they agree in theory it should work. I will be using when I get off my rig in May.
