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

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.

Interesting man. Maybe you have a special edition Z

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

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...

I never said I have some magic Z, or did I say I never had this issue, just never had it happen during autocross. You should go back, and read my posts.

Assume way, I'm 12 hours away from you. Come up to the SCCA National Tour in Packwood Wa. and you can drive my Nismo sense you're such a bada$$, and sense your seem to know my car's setup, and hell everything else.

Seriously though, it's an open invite. If you make it over this way I will be more then happy to let you drive, and maybe there is something both of us can learn in the process. That's happening July 5-6 in Packwood, WA at the former Hampton Mills Lumber Plant. PM me if you're interested.

For the record, I know just about nothing and everything I say should be taken with a grain of salt. I'm also not a "badass". I just got humbled so bad in El Toro... Went home with my tail between my legs. I have this problem where I try cars that no one has before.. Over and over. This leads to virtually no success at a national level. I like spending money that I don't have and bitching about getting pounded ... Yet, I keep coming back for more.

If your primary testing ground is Packwood, that might explain why fuel starve hasn't happened. I've been to the Packwood tours twice. Not grippy asphalt at all if I recall. Awesome site though. Very beautiful.

Is your car ASP? Would love to talk shop. I just test fit some 18x11" +20 wheels square yesterday. They fit great. Should be able to stuff 295's front and maybe as much as 315 rear without any fender modification. Are you offering a co-drive for the tour? I'd be flattered.... But I ain't running the car with half a tank. I'll get too pissed when WE do fuel stave.

Btw, if you guys are still compelled to argue please do it somewhere else. I still plan on tooling my car for STR.... For the time being. Just messing around with other stuff as well.

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.

Wow I'm Jesus Christ now! Thanks buddy I didn't think you liked me that much. Your an idiot for saying that cause that's not what I've said.

I think any spring no matter what needs preload set on the spring. If I do preload it the rear will be pretty much OEM height back there. I don't want to look like a funny car.

If you adjust ride height to adjust preload your are also moving the center of gravity of your vehicle, which could also give you negative side effects, on the road, and track. I thought I read some place you were having a traction issue, maybe something like this could be the cause.

Preloading springs on a MLS is properly done using coilovers that are not only height adjustable but also allows you to adjust the spring perch independently.
Depending on your setup, and spring rates you may not preload all your suspension when corner balancing, and in some cases you might have to add helper springs for corners that have none at all.

Hopefully this is helpful to you, or anyone else that might be looking at this dribble you continue to spout.

Or if you would rather the words of the internet;
Spring Pre-Load - Compressing a spring in advance of adding a load. For example taking a spring with a 100 pound linear spring rate, preloaded one-quarter inch, would take twenty-five pounds of force before it would further compress. In effect not moving until 26 pounds of force were applied, and only moving one-quarter inch when 50 pounds of force were applied, as opposed to the half inch the spring would have normally moved. The spring rate however has not changed, as it would continue compressing one-quarter inch for every additional 25 pounds of force applied throughout the active length of the spring, until the coils touched each other (bound).

By the way synolimit do you have a youtube channel or video links of your driving on a track, or autocrossing?

MD is a little to far for me, but if you came over here sure, and I'd let any competent person drive it.
My setup, and driving skill isn't perfect. There is always some more to learn, specially if someone is faster in my own car. I really find that exciting cause they can teach me something.
Warning if you break it you buy it.

First off its "you're". If you're going to call someone an idiot don't be one yourself.

Lmao!!

Lol you were saying? I did and it clearly says "of any kind." In English that means never, ever, ever, no matter what including street, auto, RR, hill climb, etc etc. and I'm the idiot haha.

You clearly know nothing about my setup because you refuse to read what I write! You call me out on weighing a car when the post you quoted showed the weight right there! How can it be off when its clear as day in a pic? Can you do basic math and see?

I've never said I had traction issues. I have a 300 utqg tire and a 57/43 weight ratio so it's not as good as it could be. No **** that's how you adjust height and pre load on a coilover! Hence why I asked what I asked then said ill just buy the FA shock! You seriously don't read and just like to start ****.

If and when I talk to you, you can respond. 350 got what I was saying and understood. Nothing in this thread have I said anything wrong, lied or incorrect. You've called me out 2-3 times on stuff when you don't have the facts or you just like to start ****. I've proved you wrong about my weight cause you called me a liar and yet you still try to start **** by saying the scales off when I ******* provided you proof that it wasn't. You're the only one here saying BS that your nismo, with you, and full tank was 3200! Then you gain 114lbs without you in the car without a full tank on another scale, so who wants to hear all your crap? I've at least been consistent. Get the **** out of here troll.
