    Spraying on automatic transmissions

    So it is to my understanding that it is not a good idea to spray while the automatic transmission while it is shifting. What exactly could this damage? Also when should I hit the button and what RPM do you recommend I stop holding down the button so the trans. can shift?

    There's a period where there's very little load on the tranny between gears. Being on the spray could very well cause your engine to over-rev and blow.
    They say not to shoot below 2600 rpm.
    As far as when to lift off the button, I'd pay attention to what rpms your car shifts at, and plan to come off the button a couple of hundred rpm earlier, just to be safe. That should give you a nice cushion for reaction time on your part. In the heat of the moment, it can be hard to remember to pay attention to the tach. (Especially since it'll be climbing towards redline quicker than usual)

      thanks man, I was mainly wondering about the whole engine over rev and such. It makes sense.

          im pretty sure there are systems that allow you to do this, but id rather hit the button and choose when i want the spray going.

                  Well, Im not driving the car right now, I am in the process of an F20a DOHC swap and Im going to be running a Dry kit, most likely a 75 shot. ZEX kit.

                  The motor will be pretty much brand new when it goes in the car. so it will be able to handle it.

                      Man I cant wait to start spraying the old auto. I am going to get tuned for nitrous here in the weeks to come and I will provide vids and opinions.

                        Yea, once I'm on the spray I dont know if I'll be able to control myself. I'll be going through the entire bottle in a day.

                          $5/lb. It can get expensive pretty quick.

                            yea, 50 bucks to refill the bottle everytime will get expensive. but it will be well worth it.

                              I only have the 5 lb bottle. It's a lot easier to justify a $25 fill than $50! Still haven't gotten around to actually spraying the car yet though.
