Just wondering what I would really need to spray a 100 dry shot on my heads and cam car. My car probably has about 430-440 hp at the wheels. I have a racetronix fuel pump in it already. I am mainly concerned with the fuel rail and the stock injectors. Thanks

A single racetronix pump should be fine. However, when doing the tuning i would watch fuel pressure. To be safe, throw a boost-a-pump on it or a second pump in the tank. This way you will have more then enough fuel when the nitrous bug hits. If your spraying a wet shot the injectors shouldn't matter, however that is near the limit of the stock injectors.

Thanks, so the fuel rails will be OK. But I may have to have bigger injectors. How big would i need to go?

Jake@EPP

What goals do you have for the motor in the future? If you plan on going with larger ci , i would reccomend some 42lb just beacouse you can get them pretty cheap. The stock rails are plenty for a while. If you up the shot quite a bit, it may be wise to get a fuel cell from harris or the similar.

If you are at 430-440 at the wheels on stock injectors, you are really out of injector NOW. If spraying 100 dry, you need the 42s that Jake mentioned before any of that N2O is used...

Where is the best place to get the 42 lb injectors? SVO green tops? Flow matched?
I really don't plan on spraying a lot of nitrous-150 max. Not a huge fan of nitrous, but it is a cheap way of getting a extra hundred horses.
