Congrats on the nice improvement. 28th of 94 is a great showing for your first event of the year. It took me a couple events before I get up to speed after the break.
As to your bogging problem... I really don't think it is a fuel tank (1/4 full vs. 1/2 full) issue. I have been running most events with the fuel light on, sometimes ending my runs with more than a needle's width below the red line. I have had no fuel delivery problems.
You might try replacing your fuel filter if you have not done so in a while. Additionally, you might also look into removing your upper and lower intake manifolds and giving them a good cleaning. I am definitely due for the latter.
I have noticed bogging exiting slow 180s that I did not downshift to 1st gear. The motor just doesn't pull hard from real low RPMs. Problem is that if you do downshift to 1st gear, your car is loaded up on one side exiting the turn, so now, with high RPMs and torque, you spin the inside front wheel trying to accelerate. Bit of a Catch-22.
On a side note, those SVT Foci are pretty fast through the cones. While I don't feel they are going to be competitive Divisionally or Nationally, they are capable of giving the Contour a run for its money. I just got back from a South Bend,IN event where a SVT Focus showed up on Hoosiers. I had a stellar last run, and beat him by a little bit. That run put me 2nd overall in PAX, just behind former FM National Champion Scott Nardin. I was shaking when I got out of the car. One of the corner workers came up to me as I was changing tires and told me I had the car up on two wheels through a sweeping left-hander.
I have only seen a few cars ever do that, so I it is hard for me to believe... But it was a fast run. :rolleyes:
