    How much spray on forged internals

    I've got the forged internals and solenoids to push past my previous 150HP shot. I can tune my own car, and follow the 2*/50HP rule. Usually aim for about 11.8 AFR.

    Currently I'm running the racetronix intank, lucas 42#, and stock rails. TR55 plugs. Heater w/pressure switch and a window switch is all I ever used w/the old 150HP setup. NO purge.

    I have everything I need to run 2 stages on HSW nozzles, if that makes your choice any different.

    How big can I go? Does 250HP make no sense on a single shot?

    Thanks in advance folks.

    I think you would need new plugs more then anything, get the NGK TR56s

    Plugs will get set one or two steps colder for sure.

    I'm more curious on how to set this up. I should be able to do 200HP on a single shot through the HSW kit, but I don't know if that's wise or not...

    Maybe I'll just call them tomorrow.

    The internals will be fine, but you might need a dual fuel pump setup. I just found this out... My 1'st shot is a 150 dry, then I added a 2'nd 200 shot... Felt good for 3 seconds, till it ate the plugs... Oh ya, never run super / platinum plugs. They should be able to melt, before the pistons !!! I run auto-lite 103's @ .040 gap

    I already have one walbro 255, so I figured I'd add another...

    In tank, or external? I've got an intank unit already also.

    Have you upgraded your stock fuel lines to increase flow, or are you just getting the 2nd pump for redundancy?

    I'm told that the fuel line is good ( -6an ) and to Y in the second pump in the tank, using relays off the battery, with the stock fuel pump wire energizing the relays...

    i've been 200 on a completely stock motor. you'll need to run a BP7EFS or autolite 103. on my 408, i've been 663 rwhp with a single 255lph intank walbro and a 250 shot.

    I tried 350 total, didn't work... You must be very close to your pumps limits !
    What timing are you pulling ?

    Oh yea, that's what I'm talking about. 250 shot, 1 stage? All @ once? 1st gear lock out?

    21* fuel pressure was around 45 psi.

    45 psi is cutting it a little close... With my 150 shot, I still hold close to 58 lb. When I flipped the switch for the extra 200 on top, I didn't notice the fuel presure guage... Just tried to keep the car between the lines...
