Default How full to fill fuel tank for HPDEs?

Should I start full and keep it above half all day, or try to stay at half, or what?

Its easy to top off between sessions at the track i use.

Thanks

If I'm on street tires, I can run below a quarter tank in my STI (if it's raining I can run to empty). If I'm on R-comps doing an HPDE I start to get fuel cut as I approach the quarter tank marker. Doing autocross on Hoosier A6's I have to keep it right around 1/2 a tank or I get fuel cut coming out of sharp turns. That being said, you're in an older WRX, so the fuel tank and pumps may be different.

depends on the grip level mostly... tanks are pretty much all the same.

On my RS with 245 r's i get fuel starve around 1/4 but i put in a home built surge system to help

If you aren't racing, what's the difference? Fill it up and have fun.

Bingo. You're not gaining any discernable advantage by running as little as possible and having to fill up numerous times throughout the day.

Fill it all the way up. I usually get fuel cut below half a tank in some spots, sometimes not until 1/4 tank but for an HPDE that doesn't take long to burn half a tank.

If you are really persitent on having as little gas as possible (gallon ='s 6 lbs), just find out how much your car runs through in a session and just give it a gallon or two more. (Mine kills a half tank on a fast track.) The penelty for most HPDE's for running out of gas on track is you being done for the day. So don't run out

On really hot days we prefer a full tank of fuel. you do not have to go fill it up as often. I just hate it when my beer gets warm and flat back in the paddock because I am waiting in line at the gas pumps.

My thoughts exactly. Why even risk fuel starvation if you aren't racing?
