Would you drill or cut holes in the bucket on the bottom for twin 450's? To keep fuel in the bucket?

 

Even if you have a big fuel system, I still take the advise of blown02408 and start with a larger pulley. You really don't have any idea where the thing is gonna be boost wise....so it would be smart to get a baseline to see what the boost curve is gonna look like.

 

You've got thousands of dollars in this build. Starting with a $100 pulley that you may never use again is a drop in the bucket......plus you can sell it if you don't like it.

 

Hey guys hate to barge in and clutter up your tread but I'm kinda in the same boat right now just upgraded from a d1 to and f1a also and I am worried about my fuel also and you guys seem to be pretty smart I have a stealth 340 with 1000cc injectors with a return style fuel systems and by reading this it sounds like I need to upgrade my fuel system? Any input? I was pushing 13.5 pounds with my d1 and never had any issue thanks if you can help me sorry if I'm intruding
