fuel upgrades?
fuel upgrades? 1. How much power can the factory fuel system handle on N20?
2. Also when do you need to start upgrading the fuel system when using N2O, 200 shot and above?
3. Who makes quality systems to use on the market right now?

Wet shot/ dry shot makes a difference. The dry will require more pump.. but either way its good to put a new pump in because if it fails say good bye to your motor. 150 is all i would go with stock pump, injectors. Racetronics makes very good fuel pumps..
1. You'll get varying options on this. I personally wouldn't push the factory fuel system past 440 ish rwhp. We just had a bolt on '98 that was dropping down to 35 psi on a 100 shot.
2. See above.
3. Depends on the size shot you’re going with. Under 550 575 rwhp a single intake Racetronix kit can cover you. Over that I'd do a stand alone. A racetronix kit can support more HP then that, but by the time you add a fuel rail mounted fuel pressure regulator and a few other extras it will have been less to go the stand alone route.

It depends if you have any other mods consuming more fuel, but i dont like to see anyone spray more than 150 on a stock system and if you want really air on the side of caution stay around 125 untill you upgrade your fuel pump

When i ran my dry system 125-150 shot, i put a racetronix kit in and also some injectors. When i added my 2nd stage for a 225 shot i installed a Harris Speed Works stand-alone. Best be safe than sorry.
