Fuel starvation, who else?

ban25 · 02-22-2010, 11:51 PM

I'm curious about fuel starvation off the track. Has anyone experienced the issue on a steep incline? I live in SF, so I'm a little concerned about the engine cutting out on me on a steep hill...

Yes. I've had it occur on the street with 1/4 tank on an uphill right hander driven aggressively. On a flat auto-x circuit it happens fairly consistently at 1/2 tank with long radius right handlers.

The combination of turning right and climbing seems to be the worst for pushing fuel away from the pick-up. Not very common on the street as it requires sustained lateral G's and heavy throttle.

How do you think it would react to driving up or down a street with a grade between 25 and 30%?

As long as you're not trying to re-create any movie scenes by accelerating full throttle up the hill as you fly over the cross roads I think you'll be just fine. And just to be safe fill the tank before it reaches 1/4.

Nah, wrong car for that.

Ok, thanks!
