  • Fuel Starvation

    Do any of you guys who track your car have issues with Fuel Starvation?

    Just wondering, because I saw a "solution" today, and to be honest, I wasn't aware of a problem?

    I haven't felt it in my S13, but I'm still on street tires and usually try to keep at least 1/4-3/8 of a tank in the car on track for that reason.

    I've felt it in my E36 M3 on the street at about 1/8 of a tank or less.. and they'll do it on the track at 1/2 a tank or less on R-comps... yikes.

      I typically don't have fuel starvation till around 1/8th of a tank, and it's only on one turn on our local track. Well see how that goes when I put on some R-compound tires though.

          I have ran my car down to E multiple times at the track and have noticed absolutely no fuel starvation problems at all. 240's seem to be able to pretty much suck the tank dry before they start to lose fuel pressure. Besides if you are really concerned with it get a fuel cell with a trap door arrangement. Lose weight and eliminate fuel starvation problems.

            i got fuel starvation at VIR, once, out of 8 events there, just one moment and i was running very low, usually i fill the car up to full and run it all day then fill up for the next day. Its the easiest way to prevent running out of gas and always worrying about it.

              That's what I do. I get to the track with at least 3/4 tank and run all day. By the end of the day I am about empty so I just fill up on the way home.

                Gosh, I wish I could go a track day on one tank of gas... I refill before lunch and again in the afternoon and usually have just enough to get home. The one down side of having an open track day with no sessions I guess.

                    I haven't had any issues at drift events - I only bothered mentioning this just because of how much sloshing around everything does in the process. At Summit Point after a good run my rear view mirror would be sideways, haha. I did a run there with my gas light on and had no issues, I basically started freaking out though because I didn't notice it until midway through the run, mid slide, so I just kept on it and filled up at the expensive ass gas stations at the track.
