how are you spraying it? plate or nozzle/ direct port?
plate
assuming that you have tuned your car
lower your timing 6 degrees
make sure when you run it with nitrous your AFR is below 12
Negative sir. Pull timing but keep AFR around 12-12.5 . Keeping it below 12 is old skool thinking. Now it's done by pulling more timing and leaning it out a bit more.Quote:

most people copy high to low when they are in the process of tuning once they fished the return the low oct back to it previous setting..
I would say the old school guys just didn't understand MBT as well as we do now lol... Not to mention we have nicer dynos too :)Quote:

Pull 8 deg and shoot for a air/fuel in the 12's. Nitrous is dangerous when run rich!
Someone wanna elaborate on boost + nitrous? Is 11.5 AFR safe considering 15 psi and 50 shot?

nice vidoe guys ,,
but i am not brave enough to make any Forced induction car with 12+ AFR
i would keep it below 12
as long as i tuned one of my friends car
441 engine with 300 shot ,, and i had 780 RWHP spinning on dyno ,,
and the car is still alive and he have run it more then 20 RUNS in the street + 5 on dyno
i dont know ,, u guys might me much experience then me ,, but i hope someone explain his knowlge and feed us with information ,,,
here you go the vidoe ,,
sorry the vidoe is so bad ,, because i was tuning
with low timing the car had 505 spinning a little
should be 520 MAX
300 wet shot 780 RWHP
