I am talking about the MSR-C series of turns starting at horseshoe and ending in tombstone, running CCW. Brett Gabriel has similar fuel starvation issues in his 99. Since the rule change, I dont have a stock fuel pressure regulator, I have an adjustable one located outside of the tank. I did make sure that the return hose was fastened tight and is dumping very near the pick-up. I am running 52psi of fuel pressure, but don't really monitor it in terms of logged data. I do have a pressure gauge on the regulator itself, but that is under the tank cover and I only look at it when tuning.

Oh ok. It has been years since I ran there, and then is was in a 1.6L so I don't have any experience to help you. From what you wrote, it sounds like you knew about the "side effect" issue I was alluding too with the FPR. I am still surprised though, because I have run races with the car loaded for some time with no ill effects. Was this always an issue for you or just a recent manifistation?

It might be you'll just have to run with more fuel and less lead.

Don't believe you have seen Brian, he's a tall guy (like watching a circus bear climbing into a car ). Believe he's already over weight with no ballast (2011 NASA rules), but that topic is already taking place in another thread.

Yes, I have seen him. But NASA weight rules didn't even cross my mind. But I see your point, I am not a big guy (although not a lightweight either), but I don't think I could make weight in my 99 in NASA. Maybe, if I took out every piece of optional equipment. I guess Brian will just have to race handicapped. You guys should give him a head start.

I can assure you that my driving is enough of a handicap without anything else dragging me down. I am 30lbs heavy under the new NASA rules, there is some additional weight that can come off, maybe 5lbs or so is low hanging fruit, but the rest is going to be pretty tough.

As far as the fuel starvation goes, I don't have this problem at other tracks (I have not driven TWS though). I did have this problem before I added the fuel pressure regulator. I initially thought the little return fuel hose that attaches to the stock FPR was missing, but that turned out to not be the case. For me it is not really that big a deal, I need to work on my driving more than trying to get the car another 30lbs lighter. Just thought I would throw out that one needs to actually test where there particular car will starve rather than just assuming you can run the thing basically dry.
