So I installed a Lonnie's performance twin intake system a while back for my 2000 f1 procharger build, I have been running 12lbs on the dyno and about 10ish on the street and havnt had any issue. I am thinking about putting more boost to it this fall and wondering where I'm going to run out of fuel. I have heard I should run out around 14-16lbs and about 700+hp.... I would assume I need a new supply line and some larger rails? any help would be great.

thanks guys

What I've seen is you need at least a -8 supply and -6 return with billet rails and a boost-referenced regulator. With the twin pumps, that's good to about 1000rwhp if your injectors are big enough. But the stock lines are only good to about 700rwhp. And that might be pushing it.

Yes, at about 700rwhp, you typically start to get a pressure drop at the engine due to restrictive lines & rear mounted regulator. Your pumps should be good to approx. 1000rwhp.

My injectors are Seimens 80# Ev-1, I would think they would be good up to when I need to replace the pumps correct??

So I guess my next questions would be, where and what brands should I get for the lines, rails and regulator? (BBK, Holley, etc?) and is installing the fuel lines difficult to do or just like installing Lonnie's kit (drop the tank and run new lines to the front? or is it more of a aita than that?

80s will be good. I'd buy the rail/line kit from Lonnies or Nasty Performance.

I used lonnies kit and never dropped the fuel tank. I made a trap door though lol. So much easier doing that.

Routing trying to keep everything in the stock places can be time consuming but not to bad.
