Major Track Faults of the 370

FricFrac · 02-12-2011, 07:19 PM

What about running a secondary resevoir after the tank or is that allowed?

Man I have run nearly empty and pitched the car with no issues yet? Is this a 2009 issue only?

Guess I pohang to get on track to figure this out. Can't believe no one has tackled this if it is truly an issue. I'd love to see video of it with video on fuel gauge.

Once you get on the track, you are going to feel it if you do a right hand sweeper. I am going off memory here, but I recall 6 gallons from full is the least amount I could do without fuel starve. I basically have to fill up after each session. It's annoying, especially when there is no gas at the track! You have to reset your odometer, remember the car gets 6-7mpg.

Sucks for me cause the closest track to me has a very long dirt road from the main road to the track and no gas at the track and nearest gas station is 12 miles from the track. I would end up driving over 100 miles just to fill up before/after every session. Screw that.

yup, bring 2-3 5 gallon jugs as your backup. I honestly don't recall if my car got the hick up after 1 or 2 20 minute session, I think it was 2 sessions.

Any idea if there's been any progress (short of dumping the oem fuel tank and moving to an aftermarket fuel cell etc).

Travis had someone make a mostly fix. It let him get down to about 1/4 tank on track which is a big improvement. The tank has to be sent out and modified. PM him for his contact.

Just weird that factory, Nismo team on Nismo developed car and all magazines who drove this car on the track never reported this?

So all the cars we see with in car videos on the track never having any fuel starve issues are all running with more than 3/4 of a tank?

Wonder why so few people have dealt with this issue? Baffled tank certainly would help.

There are less than a handful of people that have tracked their cars. Most people buy their Z to look cool, they are missing out half the fun.

Ya, look cool ripping into turns!

I believe that people get the Z because it is a true sports car at an affordable price.
To each his own, but it's badass that you guys track.
Love reading and checking those videos out.

It takes more than just putting the Z on the track. You have to be driving near the limit. I'm sure plenty of people drive at 7/10ths on tracks without long sweeping right-handers and don't ever get fuel starvation.

You should give it a shot. Just be smart and you will be fine. You don't want to wait till you are too old and not be able to do it

It's hard to tell people to drive balls to the wall everytime you are at the track, especially when we are not backed by sponsors or trustfunds. As long as the driver is driving at a reasonable rate (107% rule?), I don't see what is wrong driving at a pace that you are comfortable with. One thing I do hate is that people get cocky and think they are better than what they are because they compare themselves to other schmoes at some track day. If a 911 is driven by a good driver, can someone in a Miata really keep up? Come on

Huh? I wasn't being pretentious or telling people how to drive. Nor was I commenting on my own abilities. I merely stated that fuel starvation occurs under specific, rather extreme conditions.

cossie1600 · 02-13-2011, 11:02 PM

Oh yeah. There is one thing that is consistent, it is all on sweeping right hand turns.

Autox is not the same as track days!

flashburn · 02-14-2011, 08:56 AM

Last turn at Sebring, I hit some fuel starvation a little under 3/4 of a tank, and this was my first track day. Luckily when this happened it was towards the end of my 2nd session, so hopefully I won't have an issue if I fuel up after each session, once I am driving it more aggressively. Still a huge PITA though, and I wish there was an easy solution (e.g. not having to ship my tank out to get modified).

I'm sure at Sebring that would be the only turn I would have a problem with though, so if I could just tell my brain to take that turn slower than normal, I'd probably be able to avoid it completely. But what is the fun in that?

cossie1600 · 02-14-2011, 10:04 AM

Once again, hard steady right hand corner is the culprit
