Testing the new Mass Air Flow sensor at AMP<\/h4>\n\n\n\n

Track Night in the Porsche<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Just getting to Track Night was an adventure this time.  I decided to try out my new to me Ford F250\ntow vehicle.  I first took the trailer to\nwork with me before heading down to Atlanta Motorsports Park.<\/p>\n\n\n\n\n\n\n\n

When I arrived at work I saw one of the wheels had come\nloose and the lugs holes were oval shaped. \nSince they from upon doing work in the parking lot, I tried to tighten\nthe lugs a bit and get off the company property.<\/p>\n\n\n\n

The wheel seemed to be working ok, so I tried to make it to\nTractor Supply going the back roads, so I could drive slowly.  I did not make it.<\/p>\n\n\n\n

 I had to stop and\nswap on the spare wheel. Since the lug nuts were damaged I had to steal some from\nthe other wheels.  I tried running on\njust three wheels, but unlike my smaller trailer, this was not an option on the\nlarger trailer.<\/p>\n\n\n\n

I finally made it to Tractor supply and bought another spare\nwheel and tire and some more lug nuts.  I\nalso picked up a new set of studs to replace the damaged ones.  I was ready in case the damaged ones broke on\nthe way to the track.<\/p>\n\n\n\n

The rest of the trip was uneventful, and the new truck\nperformed well going over the mountain from Chatsworth to Jasper.  I really like Ford\u2019s Tow\/Haul mode on the\ntransmission.<\/p>\n\n\n\n

I made it to the track in plenty of time to unload the car and\nget registered before the driver\u2019s meeting.  \nI grabbed a BBQ sandwich from the food vendor.<\/p>\n\n\n\n

Tom met me at the track and helped me with checking the air\npressure and the oil level. Seems we still have an oil leak that I can\u2019t quite\nfigure out.  Maybe from the oil air separator<\/p>\n\n\n\n

During my first session, I found the Rouge Mass Air Flow\nsensor really allows the engine to breath much better.  The engine revs much more easily in the upper\nband.  I found myself hitting the rev\nlimiter much more than when I race on this same track back in October.<\/p>\n\n\n\n

I also had some throttle oversteer that I was not used to. I\nassume this was because the car was making more power as the suspension\nsettings are unchanged.<\/p>\n\n\n\n

I felt like I was keeping up with the fast cars in my group\nmuch better than last fall. This was hard to judge since there was different\nmix of cars and drivers at this event. \nHowever, I could count on one hand the number of times I got passed.\nLast time, I lost count and I had a hard time getting a full lap without\nneeding to point someone by.<\/p>\n\n\n\n

The trip home was uneventful. I was much relieved to have\nthe trailer safely parked in front of the shop. I will begin repairs to the hub\nright away.  <\/p>\n\n\n\n

I noticed a few items that need to be address before the\nnext track event.  There was a vibration\nin the right front wheel when it was heavily loaded.  I am guessing that is a wheel bearing\nissue.  Since I have to replace the brake\nrotors any way, I will swap out the wheel bearing at the same time.<\/p>\n\n\n\n

I also noticed an odd whirring noise when idling on the grid\nwith transmission in neutral. I suspect this is due to failing torque tube\nbearings. I have been shopping for the right parts to rebuild.  I will probably address this when I change\nflywheels. <\/p>\n\n\n\n

Also, one-time on the grid the alternator belt was\nsquealing. The noise went away with just a little RPM increase.   Since the brake ducts have to come off to\ntighten he belt, I did not address this at the track.  I will have to see what cause the belt to get\nloose.<\/p>\n\n\n\n

Update:<\/p>\n\n\n\n

The oil leak does seem to be coming form the oil air\nseparator. I will try changing the O rings.<\/p>\n\n\n\n

The whirring sound was indeed a bad torque tube\nbearing.  I have removed the bearings and\nordered more.<\/p>\n\n\n\n

Actual lap times were a second or so slower than in October.\nProbably due to worn tires or track temperature.<\/p>\n\n\n\n
