I have these two in my car and am wondering which will run out first? If I am to push around 350whp, will the fuel pump be reliable enough? What if I were to upgrade to 720cc injectors? Any insight would be appreciated.

 

That is a kick *** fuel pump....it pushes enough go juice to keep you safe for real high power....Im sure close to 500.....if you have problems go with an aeromotive...they make HUGE pumps

 

I heard the Aeromotive in a Civic and it's kind of loud. I am hoping I won't have to move to that and keep the intank pump. But then again, I don't want to be running lean at high boost either. Thanks for the reply.

 

The stock pump can handle 350hp at stock pressure. The Walbro can easily handle it and much more.

 

Ah good to know thanks. I really didn't want to have to go with a noisy external pump. Hopefully nothing will blow on Saturday heh.

 

You'll run out of injector way before you start maxing out the pump......550's at stock pressure are only good for low-mid 300's.......you can start turning up the pressure, but I'd just get bigger injectors........780cc's are great
