Stock fuel lines capacity

Stock fuel lines capacity

Hi there everyone,

I'm blowing my brains out with this thought and might want some feedback if it might be possible or if I'm just crazy.

 

So my question is the following.. how far can you go with the stock fuel lines on hp figures? And how does that work in relation when you are doing drag racing or let's say skids/drifting on the road..?? I do believe there might be air pockets in the fuel lines while doing skids, is this applicable on drag racing as well? 

The reason I'm asking is because I hear allot that the fuel in our tanks might swirl all around creating air pockets and eventually lead to leaning out or even worst. I currently have two pistons that are toasted and was wondering if this might have happened to me.

 I have a R33 And my fuel lines are as following..  Where  The rubber factory lines start from the firewall I had all those lines removed and used -6 AN nylon braided lines to feed the fuel rail as well as to the return etc.

My current setup is a precision 6262 BB turbo. Ems stinger Ecu, aeromotive 340 lph fuel pump with 630 cc top feed injectors. Side mounth intake. Stock rotating assembly.

Setup is tunned to be rich at top load due to bad pump gas octane at my place, AFR  is between 11.4 -11.8 on load.

if any body can help with feedback on how far they went on stock lines what setup running and also opinions and beliefs behind the fuel surge scene.

 

thanks

Get a surge tank. You will be fine.

Thanks mate. i believe that is the only way left to upgrade the fuel system and still be "streetable"

Im at around 450rwkw on e85 and apart for injectors only upgrade to the fuel system is the fuel pump.

[K.koolman]

What fuel pump are you using?. Is your rotating assembly modified? 

 

Where I live e85 is only sold as race gas we do not have it at gas stations.. only crappy 93 octane
