So, I'm just starting autocrossing also. Did a few events last season and first Summer Series race is this Sunday. What tires are you using and what other suspension mods have you made that mattered (more than learning how to drive right)? Also, I found the tail really wants to swing out with street tires, and I played with air pressure and it helped a bit. Will R-compound tires change that preference for oversteer? Do you think I should leave the spare tire in and race with a full tank to weight the back wheels more? or does that create too much lateral force to swing it out? Or do I just need to slow my arse down going into the turns :-) -
I was searching the web to find someone with the same "below 1/2 tank" problem and I found this thread. But, mine's fuel-injected with an electric fuel pump at the tank, and I replaced most of the high pressure side hoses (e.g., tank to pump, pump to regulator, regulator to metal line, little ones under the hood). I replaced the fuel filter, too. I've had the tank sending unit out, but did not think to try to look inside at the condition of the tank for sludge/crud. Maybe next time. But, most of the time, especially in the summer, when I get below 1/2 tank it stalls/cuts out. It recovers while rolling, but cuts out again. Sometimes it does not recover until I add 5 gallons of gas. Once I do, it runs great. I recently filled it with premium because I was auto-crossing and I ran that tank to E with no problems. So, maybe it's more like occasional crud blockage and the premium has nothing to do with it? The only hoses I have not replaced are the low pressure side, vapor returns, etc. Bill D.

MidWest Z Fest http://www.zccc.org/mzfa.htm The 2009 Midwest Z Fest will be hosted by the Z Car Club of Colorado. We have four days of Z events planned including - Track Event at the all new High Plains Raceway Shine and Show Mountain Drives Awards Banquet We are planning the variety of events to offer something for everyone. ¤ There are two mountain drives that take you up into the beautiful Rocky Mountains, highlighting the handling of your Z. ¤ For the track enthusiasts, we will have a track day at the brand new High Plains Raceway. Typically, there are four classes from novice to expert. These are not races but a chance to drive in a high performance manner- you and your car against the track. The HPR track has been a project for all the motorsports clubs in the Denver metro area for several years and in the fall of 2008, the paving was completed. While there is still work to be done to finish the facility, it's already clear that the track itself is one of the most challenging in North America with nearly 70 feet of elevation changes. We will be updating this information as the planning progresses. In the mean time, set aside these dates and plan to visit us in Colorado.
