Reply With QuoteI don't know why your car did that,but for reference I have run the track plenty of times with the needle just at E and have never had a loss of power,rev limiter yes ,but not low fuel
Yesterday, I went through a set of carousel turns at the track, with about a 1/3 tank (maybe 1/4 tank), coming out, needle was down to E and I hit fuel cut for a brief moment, then the needle went back up. I obviously knew the gas would slosh around, but not that much to miss the pickup.
Is that to be expected, starting around a 1/3 tank? I know we can baffle our oil pans, but is there any solution to the gas tank other than being sure you have 1/2 tank or more?

Hmm.. it's POSSIBLE I hit the rev limiter, it was pretty close to a shift point, but that would surprise me. I just remember when I immediately glanced down, the needle was right on E...Originally Posted by docjohn

Were you overheating? Rev limiter kicks in sooner (~7k) when you start to overheat..

i noticed the same problem for mine too, and it's only happened at higher rpm with higher speed g loading. Mine happens in left turn for the 2 tracks that i went to. It usually happens when the fuel is low and/or track temp is higher.
My mechanic thinks the old fuel pump is the culprit; while I also wonder since it's kind of related to heat. (I never had this problem until later of the day or after lunch.) It could be the fuel pump relay...
please do keep us inform if you fix the problem.
Was not overheating, track temps were cool, air temp was about 60.

i noticed the fuel gauge showing lower too, but did not experience any fuel cutoff. i did fuel up to be safe, though.

overheating regards to that little metal heat sink by the right side, the fuel pump relay. again, I just speculating at this point.
If that's the case, how is it correctable?

Same here...I don't know why your car did that,but for reference I have run the track plenty of times with the needle just at E and have never had a loss of power,rev limiter yes ,but not low fuel
NSX. Spread the word.
if I have chance to get hold of a new one, then I can identify/isolate the problem.
anyone recommend a walbro fuel pump or a new oem unit?
It happened to me two time on left turns when I was 1/4-1/3 of the tank.
Rev limiter can also cut in with cold engine at 7K. Was it your first lap? I've run with 1/4 tank and never had a problem (OEM fuel pump).
Ran an autocross yesterday and started with the needle on E, no fuel cut through any of the horseshoe turns. not the same length of g-load, but I *might* have had 2 gallons in the tank at the time.
I've seen my needle hit E from slosh on the track, but haven't experienced any fuel starve there either.

Ive found that if I am below 2/3 of a tank at the end of a 20 min session the gauge will read empty, I dont get cut outs though and the needle rises slowly again after I am still for a bit.
That's the same thing I get.

I was about 15 minutes into a 20 minute run.

When was the last time you checked your fuel filter. In my scenario at Infineon turn 10 - the last place you want this to happen, the culprit was a dirty fuel filter (about 9 years old with 45K miles)
2nd owner of the car, I've personally never checked the fuel filter. If mine is original, then it would be 8 years old with 70k. I guess it wouldn't hurt to check it and replace it.
Should I stick with OEM or is there another fuel filter of choice? Where is it located and how easy to replace?

Since the fuel system is pressurized, it's hard to believe that a fuel filter would delay fuel only in turns
The OEM filter isn't very exspensive but it can be a PITA to replace. If you have an impact wrench be sure to use it. The bolts are very stubborn to remove and the filter hard to hold onto to. Located on the passenger side engine compartment near the firewall (easy to see and access).

I'd be interested to hear what Billy would have to say on this topic....

In the maintenance schedule in the owner's manual and service manual, Honda/Acura recommends replacing the fuel filter and rubber fuel lines/hoses every 60K miles or 4 years, whichever comes first.

Wow fuel cut with a 1/3rd tank... i've had 1-2 gallons in my car and never hit fuel cut in a loaded turn...
I suspect something else...
