Major Track Faults of the 370

yep, and the carousel at Road America is the absolute worst! Its such a fun corner to exit all out, and the car wouldn't let me

At least when I go to Summit Point this year the Karussel is a left hander.

Looks like the two big sweeping turns at Atlanta Motorsports Park are both left, so that's good. I was especially worried about that track because of the elevation changes and the banking on some of the turns.

Any issues at Road Atlanta or Miami-Homestead?

OK so guess rather than fixing it I will just drive tracks with Left hand turns.

Let me see. ...Laguna Seca is good! Only 3 real right handers.

Infineon is bad. Lots of right handers some with elevation changes.

Or maybe I can figure out a fix. LOL! I still cant believe people have been tracking these cars for nearly 3 years without looking at this seriously if its truly an issue.

Well, we know what the issue is (U shaped gas tank), but there just doesn't seem to be an "easy" solution.

It wouldn't surprise me if you get the cut out in T1. That type of long right hand corner will get you fuel starve. Now that I think about it, maybe the two turns after hte caroussel. If I recall correctly, Summit Point has gas station. If not, you are screwed as the nearest gas station if a few miles away. Bring 2 5 gallon jugs and fill it after each sessions

Yes, I always bring 2 fuel jugs with me. I don't like driving off to get fuel every session. Plus this will be an open track event, will be able to run for any length of time at any time.

Road Atlanta turns 1 and 7. I actually stalled coming out of 7 and had to get the car towed off. that is how I discovered it.

That sucks. Wish there was an easy fix for this.

Mike · 02-14-2011, 03:35 PM

easiest is to just fill up between sessions. The only place where it has really been a problem is Road America, and I probably won't be there again. There I was getting it at one dot from full, but the Carousel exits at over 100mph and really pulls some right hand g's.

Shamu · 02-14-2011, 03:40 PM

Im a long term Porsche guy and I will go after this. When my carbs were fuel starved on the track I had them custom baffled, when I got vapor lock I changed lines and put different pump in place, etc.

I'm sure there is a simple elegant solution. I just need to see diagrams etc. We cant have our Z's choking for fuel on the track. Thats just unacceptable in my book. Running a full tank isnt a solution.

cossie1600 · 02-14-2011, 04:57 PM

If you can come up with a CHEAP fix, we would appreciate it.

Here is another tip. Bring multiple credit cards with you, the machines usually don't like you swiping at the gas station every 30 minutes!

flashburn · 02-14-2011, 06:20 PM

I think I'm going to just do what Mike does (for now) and bring some 5 gallon jugs with me when I go to Sebring.

I think with 2 5 Gallon jugs, that should be just enough for 4 track sessions, give or take.

edit: Actually, since I have the Zenclosures sub box, I'm not sure I can fit 2 5 gallon jugs in my trunk.

Shamu · 02-14-2011, 09:15 PM

So how much more weight are you willing to haul around? Gas weighs 6.1 lbs per gallon. I guess only positive is that weight is being added to rear of the car. But if I can run with say 12 gallons less that means I'd be running 73 lbs less than someone who hasn't fixed this issue.

Lol! Cheap? Probably not. But what's 50lbs plus of weight reduction worth to you?
