You're playing with fire sir !!! Still no fuel starvation? EVERY single guy I ran into autox events, they all said the same thing,"yeah gotta keep the tank full or else fuel starvation." I haven't hit fuel starvation yet but I ALWAYS run full tank. My longer autox event drive (2 hours from my house), I stop 20 mile before autox venue and fill up.

Actually, I need to keep a track of how many events you do with 3/8th full tank until you hit the fuel starvation. Just for the sake of gather data. What year Z btw? Any video of your Z running at the event?


MIke STR: How do you cope with tire pressure increase? You simple check before event and run all day? I run 37F, 38R and sometimes I find myself running at 45-46 psi hot! Do you go out and check pressure/adjust before each run?

Now that's close! lol How you didn't knock that cone over as your hands are still turning, is a mystery! lol

BTW, your video has that black surround can be taken out with 3 second option change. Are you using Window Movie Maker to finalize video?

LOL! Yes. Windows movie maker... I'm cheap.

I have an 2009 Nismo, and you can find all my last year autoX runs at https://www.youtube.com/user/Apollo240sx In the SSCC autoX videos I don't think I ever ran less then a half tank on their track. I figure the sweeper might do the trick, but still have never had a problem there regarding fuel.

Just to be clear my car has been fuel starved on the track, but never auto crossing. For the Oregon SCCA Solo we usually only get five runs, and they are pretty small, usually always sub one minute. As for the national events up at Packwood Wa they are one minute and up. I've never burn threw a huge amount of fuel where I've been worried.

There are now two other 370Z's running in the scca autox group with me, so I'll have to ask them what they are doing.

Yeah. I have a friend that will check my pressure while I'm in line. Front pressure builds so much faster than back.. but that's where all the weight is.

The car seemed to do the best with 37 front / 35 rear psi.

Mike, do this. Takes 3s but it'll remove the ugly black strip around your video. (i'm assuming you're recording wide screen)

Interesting man. Maybe you have a special edition Z

Thank you. I have a BMWCCA Autox event coming up on 4/27. I'll try it out.

Yup, it still gets fuel starvation issues on the track, so it can't be that special, I wish it was though, cause that would be cool.

No offense.. but you just aren't generating enough G force, driving hard enough, or trail braking into large sweepers while AutoXing. I never ran into it until I tweaked my suspension and added some camber. Once I got the car to actually generate a lateral G.... it would fuel stave like crazy.

At a test n tune this spring I decided to **** around with the car at 1/3 tank... I literally thought I broke the car. It fuel starved for a good 40 seconds. I was dumbfounded.

Fuel starve is only momentary at autoX if you have 3/4 tank. Maybe a second (feels like an eternity). I'd rather run a full tank and take the weight penalty than run into fuel starve again.

No offence but you really can't talk sh!t when neither of us have a proper data logger, and G meter so see if that's true, or not. I would really like to compare note on that if we did.

synolimit WTF are you talking about now? That makes absolutely no sense when it comes to how the suspesion works on these cars.

Look, it's a factual statement. Maybe you haven't encountered the right course on the right surface. I have no idea. Bottom line, your car is not generating the same g force in certain elements that mine is (assuming same surface and similar elements). There is no magic 370z that doesn't get fuel starve.

Once again, you could be on asphalt all the time. I don't know. You might never have fast right hand sweepers.. I don't know...

Dude Jesus Christ, go away. If you can't read whats been said then don't say anything at all. Take your Jesus mobile that's better than all our since it can't fuel starve and go away.
