Now, I'm thinking I may have problems.. Am I over thinking this? I'd Rather spend extra money now and do it right first time.. suggestions..

I do mostly street driving, with some track time.. I'd like to get into autocross, but not on regular basis..

I drive and race my car hard. It has a ricks tank with internal walbro pump and an external vette regulator. I can run down to 1/2 tank on track with race tires no problem. On the street I can go close to empty with no problems.

At Gingerman last June I started with a full tank and made it to the 3rd 20 min session when I started to feel the fuel starvation in extended cornering situations. My setup is currently 420 rwhp and will drop to roughly 6 mpg on the track.
