Nitrous for an automatic???

Question

Is it bad/dangerous to use spray on a 2003 Mustang GT with an automatic transmission? It would be about a 100 shot. I've heard horror stories about blowing holes through engines and cracked blocks with nitrous when shifting at the wrong time. Would it be alright for my car?

Answer 1

Hello nitrous systems vary widly. However a good nitrous system has kill switches to protect the engine from leaning out with less fuel then needed. Most often this is the cause of sever engine damage . It is the lack of proper fuel metering to insrease the fuel with the horsepower boost. Larger injectors flowing more fuel as well as a higher pressure fuel pump is often nessesary . Keep in mind that yuor transmission will have less mile the harder you make it work .

Absorbing and transfering 40 -100 horsepower is hard on a stock automatic transmission and the delicate small clutches inside. The fluid should be changed more frequent with any preformance increase to keep the auto trans fluid from burning.

Nitrous is not a simple subject and cannot be answered with a few paragraghs though .
Beef up your transmission and the engine / bottom end and valve tran. then when you do get nitrous your engine and trans can better handle the increased power.

Answer 2

Even automatic transmissions shift at or near redline at full throttle. Since you would only ever use nitrous at full throttle, that would mean that your transmission would shift fine when the nitrous is engaged. My only concern would be how much your tranny can handle, but the bottom line is that you'd be okay as long as you aren't too ambitious in your jetting.

Answer 3

most of the blown engine stories come from running less fuel than you need with the No2 , you could easily wire a rev. limiter in there to kill the No2 and the ignition if it threatens to over-rev. good luck , have fun
