Fuel starvation, who else?

ArtVandaleigh · 05-22-2011, 07:34 PM

Ha, glad I saw this thread... I had the same issue for the first time today doing a time trial event. I have not experienced this yet owning the car for over 2 1/2 years now, but it happened to be on a right hand sweeper, with oil temps around 255 and mid-rpm 3rd gear. Same fuel cut each time on the same corner... definitely a bummer though, I had well over a half tank too. I initially thought the car was going into limp mode, but after a few seconds of nothing, I could accelerate again. Odd that Nissan never caught this in testing?

Basically anything is difficult because the gas tank is a sealed unit with two peepholes. Short of replacing the gas tank or modifing the pickup point (which I dont think you can), you are better off carrying a 5 gallon jug...

Whatever happened w/ this, Travis?

sarmyth · 05-08-2011, 08:09 PM

I ran into this issue this weekend at the track, just below half full on gas with a particular long sweeping right hand turn.... Happened three laps in a row exact same spot and symptom, engine pegs at 6k for a couple seconds then releases. Filled up and no problems... On goodrich r1s about 100 degrees out, oil at 260.

For those who've blazed this trail already, any solutions short of a surge tank?

Sorry guys, I'm laying low... new job, new house, etc... haven't been putting this tank setup to test, and last few times I did, it allowed me to get to about 1/2 a tank with no fuel starvation... keep in mind, I'm pulling some very heavy G's with race slicks... I think it is good enough for most especially if tweaked... I don't represent the vendor - someone is going to have to call him and prod him a bit to get him to fully commercialize it... richard@nohotwire.com... he'll probably say he's waiting on me to document the install some more, but I just don't have time right now, unfortunately

YOU THINK YOUR LIFE PROBLEMS ARE OF OUR CONCERN, TRAVIS?! GET OUT THERE AND TEST, GOD DAMNIT!

Just kidding, sounds like its a start at least

I doubt they've fixed the problem in the 2011's.

Hey guys, I dont know where this ended up, but I was talking to a fabricator yesterday who said he could make me a surge tank with twin racing Bosch pumps for near $1500 all said and done. That would completely fix this problem. Anyone interested?

ChrisSlicks · 07-15-2011, 12:17 PM

Where would he locate the surge tank? Per club rules I'm not allowed any fuel lines in the passenger compartment, which in the case of the Z includes the trunk.

cossie1600 · 07-15-2011, 01:04 PM

How about an external surge tank, is there enough space underneath the car?

$1500, i can buy tons of $5 gallon jug and a dedicated trailer...

Yeah, but I've gotten to where I can't run longer than fifteen minute sessions before it happens to me now.

It all depends on the tires. On street tires you are okay for 20 minutes, on race tires the extra G loads pushes even more fuel away so it happens sooner.

15 minutes was on AD08s at VIR and about 20 minutes at Barber
