    maybe the lt's and such led to the a/f numbers in and of themselves ?

    my na numbers stay right at 13.02-13.03. it just needs retuned and possibly a fuel pump, maybe injectors. i'm glad i did put it on the dyno or i could have this thing in pieces after a few more runs.

    holy crap man..... what kit were you using? that would be the sleeper from hell, i dont think anyone would bet that a stock ls1 with just a nitrous kit would be ballsy enough to spray a 300 shot and run high to mid 10's!! you could take lunch money left and right!!! that is awesome man and makes me feel much better about spraying my little 75 or 100 shot....

    high 10's NO issues.
    I just do it on the safe side and up jet the fuel side and run VP C12 straight race gas and a set of AR93 race plugs and a Walbro 255 pump.

    On 250 we usually get 3-4 passes.

    Regular 10lb . We gravity fill and can usually get a little over 11lbs in them just fine.
    Don't be afraid of the bottle!!! Be afraid of your tune!!!

    Most anything over a 175 shot would be best delivered in 2 stages or direct port setups.

    So 175 and above is considered higher shots then?
    Like 75 and 100, or 50 amd 125?
    I saw someone said they ran 300 which sounds like definitely high HP.
    I was wondering if the hit was delayed so the HP and torque would not overwhelm the converter and rear end, or how those shots are being handled?

    Thanks

    Generally, the 1st stage hits all at once(commonly 100-150hp), then at a later point in your RPM range the 2nd stage is brought in with a progressive controller which limits the shock factor the motor and drive line experiences with that much spray.

    i would also be VERY interested in more info on running a 300 shot and high 10's on a stock ls1!! that has to be some kind of record for a stock longblock power adder ls1 for sure!~

    stock rear end?
    nitrous kit used? sounds like must have been dual stage.
    how much timing did you pull?
    ever do this with an M6?
    tires?
    how long did this car last? how many sprays? what broke first?
    what would you do different if you do it again?

    i will soon have a second car anyway and would be funny to spray some huge shots on my car and surprise some 10 second cars i'll most likely try this next year and if i blow it up, just a good excuse to build it better later

    The diff will go first, seeing as you need a MT ET Street or flat out slick to hook that kind of power. The M6 will take it, but your clutch won't if its still the stock 99 unit. Octane helps reduce any knocking, but if its tuned well you shouldnt need 116 at all.

    IF you do this, PLEASE have the car tuned on a wideband and a dyno. You'll be surprised how long the LS1 will be willing to take the beating IF you do it right the first time.

    tuner, you said you have sprayed your car 600hp? 2-stage with fogger? Are we still talking LS1, and how hard are you turning this motor? CI? Full drag car? Very interested in this.

    We've sprayed up to a 250 on a single stage (through a single nozzle) a couple times, but we prefer to keep it 200 or less....You really get to the point where, regardless of it being staged or not, you need a separate fuel system for the juice (or a seriously beefed up stock style)...
