you may just have a bad fuel pump or something if you had fuel starve at low G's. i'd say look into it.

as for the dragon if you take it on at speed then i think it becomes quite like a track but probably harder than most. might not be as fast but the turns come much faster and some are really tight. plus you only have 1 lane to use not a whole width of a track......oh yea and cops. difficulty seems to fall in favor of the dragon here lol

11 miles - 318 turns. how many does your track have

I give up. You just don't understand the difference of a turn, the G's you pull, the duration needed in that turn etc to empty and dry out the purge container.

but you're going right and left quickly so fuel just splashes over the hump to the right saddle while making a quick left, probably.

how about slowing down on public roads? no need to be going 85mph on an entrance ramp. if you're having issues on a road course, wasn't there some vendor here that has a cure for this issue?

Drex · 07-23-2013, 08:09 PM

i wonder if getting stickier tires contributes to this? how many that have had this problem are still on the stock re050s vs better tires?

and you won't get it on the dragon. Coming out of a turn there, you can't be on the throttle long enough to get it. Its definitely real and his fuel pump isn't failing.

I got it at 15/16ths of a tank at Road America coming out of the super long carousel at 105mph. Its a design flaw, pure and simple. It takes a prolonged full throttle acceleration coming out of a turn. My student was getting it at VIR this weekend at nearing the end of 25 minute sessions after a full fill up each time.

I don't get it anymore, but I have phunk's redesigned fuel system.

I can't believe all the problems this car is having at 25K miles. I had it towed last night from fuel starvation. The transmission bearings are whining so hard that I have to push the clutch in at the drive thru to not hear it. There is also the transmission grinding 2nd gear almost every other shift. The build quality is pathetic. As much as I love this vehicle, I might have to start looking for a new ride sooner or later.

I briefly considered leasing a Leaf, but f Nissan and their products

Every one doing 50 on a sweeping right off ramp type situation probally would never had a problem, but that's not really pushing the car at all not even close.

Like Mitco I was maintaining a speed of 80-85 through 3 right handed off ramps in a row ( 3 leafs of the clover) would of been 4 until the exit of the 3rd when I put my foot down on the gas and just slowed down.

You need huge force to the left side for a well maintained period of time no other way of fuel starve happening

The dragon is more like a mild autoX course than a road course.

You'll see fuel starve on the turns you can gas out of, and a good bit on hellbender if you push it (but you're really getting into the "dumb" region at that point)

so in other words you need to be doing at least double the speed limit of most on/off ramps in order to run into fuel starve a.k.a breaking the law

On the second time I got towed, I was doing 25-30mph around the turn with one hand on my cell phone. Take a look at the fuel tank and the design of the fuel pump, you will know why.

I definitely wasn't going faster than highway speed because I had hit the gas to merge with the truckers going about 70mph. The car just hesitated and died.

This is not exactly true. (See Example Below) I think a lot of factors play into how/when this can happen. I have also had it happen enough now that I can feel when im pushing the corner to hard in relation to my fuel level.

This is a fuel starve corner for me at anything below half a tank. It is a short corner but has a nice bank to it that allows you to come in pretty hot. The lines are not exact but you get the idea. Yellow section is maintaining/rolling on throttle, Green section is WOT, Red section you guessed it, fuel starve.

This next example is how you describe it and has effected me at 3/4 of a tank once.

Color chart is the same as above. This turn is obviously much longer and has a much higher exit speed than the first corner. If you notice though in both scenarios I have not been effected until being WOT in the exit of the corner.

Again im boosted and require more fuel so maybe it hits me sooner?
