Time to upgrade fuel system?
Hey guys.. I am currently running 28 lb injectors and stock pump (71k miles).. I have full bolt on's and a 150 shot through a plate system from nitrous outlet.. I am now adding a cam package from Tick.. 233 236 619 578 on a 112.. I know that will put me past the stock system abilities.. Would you guys recomend a BAP??.. a Walbro??.. Both?? And as far as injectors go.. Since its a wet system I only need to support my N/A numbers right?? Since the fuel is added through the N2O system when in use.. Maybe I am on crack lol.. if I need them would you go 42?? or would you go to 60??

Unless you are running a separate fuel system for the wet nitrous, NO. It will only make fuel delivery even more important.
Unlike cams and many mods, fuel system is one where you can overdo it and still be OK.
I would run both a walbro and a BAP and upgrade the wiring as well.
You might get away with one or the other, but especially given the potential consequences of leaning out on spray, why risk it?
Discuss your long term goals with your tuner to select your injectors.

what is your Injector Duty Cycle? that is the importat question when the Cam goes in.
42lb injectors will get you where you want unless you go E85 the you will want 60lb injectors NA. When the fuel in your WET NO2 activates you will need to keep feeding the injectors as well as the NO2 system so you will want a good pump, harness. few venders offer them. Casper and Racetronix have made things for my other GM cars might check there. I dont think you will need a Boost-A-Pump with a good intank and a harness but it wont hurt, never had them on any of my cars.

Ok guys.. I have no idea why I forgot to budget the injectors and pump into the cam swap.. Now I have to pry the money away from my wife lol.. Looks like the pump and harness are 300 and I'm guessing 350 on the injectors.. Cam swap just got more expensive lmao
