Fuel starvation, who else?

travisjb

ok no prob. hope it goes well, we need to test different alternatives so thanks for your work. I'll stick with my plan to fab and test a basic $10 perforated 'coffee can' solution and will also come back here and post results.

yea but i rememberd that you guys said it would be in the 2k range for one(i think). this is much cheaper.

the external swirl pot is nice and all, but I really dont like the idea of a pot of gasoline being in the interior of my car in the event of a collision. especially when there is a pump constantly pumping into that pot... and if the pot were to rupture.. hopefully someone is conscious to shut off the in-tank pump that is pumping gasoline into the interior. I look at it sorta like trying to put a mechanical fuel pressure gauge in interior... just cant say that im a fan of pressurized fuel lines feeding the cabin. maybe in a race car with an added rear fire-wall, but not a street car on the track. IMHO anyways.

Yes, for many states having fuel lines running inside the car is illegal and you will fail a safety inspection if they see it. This includes mechanical fuel pressure gauges, etc. If it's a race car then the sanctioning bodies have their own rules on how and where this can be done.

If it were UNDER the car somehow, I'd like that idea. In-car...no way for me...might as well stick some dynamite under my driver seat...I'd be just as comfortable...

this is definitely a possibility but unfortunately you will most likely end up with a pot using more horizontal real estate rather than vertical, and adequate displacement will be an issue.

now take that thing you see there, and throw it inside the gas tank. thats the idea we are working with right now.

unfortunately this week we were really busy between machining parts that need to ship out next week and dealing with a bad sensor on one of the CNCs causing annoyances. next week we should have time to make more progress with our in-tank project... and possibly get a prototype or two shipped out for testing.

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...

ChrisSlicks

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.

ban25

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

ChrisSlicks

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.
