Fuel starvation, who else?

Zxces50 · 06-26-2010, 06:07 PM

Did Monticello yesterday- last session died on right hander- clearly fuel starvation- could not re-start- course red flagged and I towed off- disconnected battery and restarted fine- like nothing ever happened- about 1-2 dots below half tank. Oddly 2010 Nismo was in group after me he had exact same problem but managed to get off track - we each had about same # laps and both gauges just about half full- other than fuel starvation all else good- great track

It depends where the fuel cut hits that determines whether it will pick up again or stall out. If you are accelerating up hill when you get the cut you will stall out if you don't make it to a crest quickly.

Monticello is a very nice track, some others in our Boston group were there a few weeks ago. Hoping to get there myself sometime soon.

Any updates?

reportedly (check my journal) nissan mo sports is working on an in tank setup where there will be a fuel pickup point on each side of the tank... will be offered as a retrofit where you send them your tank then retrofit and send back... they have a partner helping with this that i have contacted via email but i haven't heard back... i think perhaps stan is the test car

UPDATE: out of pure coincidence, Richard from no hot wire racing just called me... I'm the new guinea pig! will update on my journal

Awesome! I'm subscribed in your thread already. About time someone takes the lead on this!

I'll just pipe in: Me too! It happened 3-4 times out on the street when tank was between 3-6 dots showing on fuel gauge. Once I figured it out, I never run it hard when I'm low on fuel.

Good news Travis. Looking forward to your test results! I was plagued by fuel cuts yesterday, just small ones but annoying.

What's the time line looking like for this to hit the market ? You already testing as we speak ?

There is no official timeline yet... and I can't speak for him... all I can tell you is that he has my tank in Cali right now and they are trying different things out on fitment and parts... he intends to have it back to me by end of month... I have a potential event early Sep then another late Sep, and will report out on results then. And in the meantime if I get pictures or any other update, you guys will be the first to know. Thx.

Atta boy..

No pictures just yet but I did talk to Richard today... he's honing in on a price and it's going to depend on whether he needs to add a baffle or in-tank swirl pot, or if we can get away with none... right now we're thinking none and will prob test it without... so the parts involved will include the two pumps strategically placed in the tank and all the equipment to make them work... pics and testing by end of month... bottom line, I suspect pricing will be on the order of $500-800 for a kit that is mailed to you directly and can be DIY or professionally installed... assuming for now that it will eliminate the fuel starvation issue 100% and also not be a penalty for classing (with NASA or whoever) but won't know for sure until end of month... all for now

This is scary when you throw forced induction into the mix...

... nothing like fuel cutting out on you at full boost.

travisjb · 09-03-2010, 07:20 PM

Fuel tank is on the way back to me and will be installed next week... then ready for testing!

+1 on the weight saving nothing having to run a full tank.

Were in the process of putting together a swirl pot and small pump for our car.

Here's a simular set-up I had in my GTR, something like this (smaller scale) would be perfect.

I have the same problem on my 09 NISMO-Z. Ran out of fuel, (with 1/2 tank) at Thunderhill Raceway, Willows Ca. Had to come in on the hook truck, (embarrasing to say the least).

I have looked at all the threads on this problem and this is the first post I have seen with a possible cure. Need to know more! (LeesZs). :>)

soon my friend, very soon... in fact, I may have some pics to post next few days
