The SoCal club racing "off season" of 5 weeks is upon us so I put together my list of maintenance that needs to be performed and it looks like I'm going to be busy...
  • Remove 15 lbs of weight (to counter the added weight of the oil sump skid plate)
  • Replace instrument cluster (to get fuel gauge working)
  • Replace AOS (I interpret the occasional big puff of grey smoke when exiting a corner as a warning of impending failure)
  • Replace ignition switch (occasional weird electrical gremlins)
  • Replace fuel filter (maintanence)
  • Replace brake pads & rotors (worn out)
  • Bleed brakes and clutch/top up fluid (while I'm doing the pads/rotors)
  • Replace windshield (heavily scratched from debris impacts)
  • Replace spark plugs (maintenance)
  • Replace fuel injectors (they've never been touched and they can't last forever)
  • Replace drivers seat (out of certification date for 2018 and want a containment seat anyway)
  • Install front radiator screens (protect those new radiators that we installed in March)
  • Find/fix wiring fault for cool shirt system power (come summer that cool shirt system is pretty nice to have)
The task I dread the most is replacing the ignition switch. That job looks to be even a bigger PITA since the cage blocks access via the drivers side floor. Its going to be a busy 5 weeks.

Have you considered sending the fuel injectors off for cleaning and testing?

I would definitely clean and flow test vs. replace.

  • Remove 15 lbs of weight
  • That's going to be tough over the holidays... :-)

Are you going with a push button to start?

I did mine mostly through the headlamp switch and by removing one of the AC tubes under the steering wheel, which may already be removed for you. That might give you some room to make up for the bars.

Hey Tom, I still have some nearly new 986 Zimmerman rotors and racing pads in my garage. Come over and help me clean the garage.

I thought about it but don't know anyone that I'd trust to do it and I worry that they will sit somewhere for several weeks. Do new injectors have that much variation?

No, just replace the stock ignition switch (electrical portion) with a new one. On two occasions I've experienced some weird electrical phenomena and thought I'd start there.

I've used WitchHunter Performance - Injector Cleaning & Flow Testing Services in the past with no issues. A good friend just used http://injectorrepair.com/ and was happy with the timing and results.

Excellent! Thanks for the links. 5 days or less is easily within my time horizon.

Dave, thanks for the rotors and pads (and delivery!). It was nice to hang out with your and your brother for a bit. See you soon.

Here are a few pics while I am editing video...

This is the start of Race #1. In order from front to rear; Malcolm Van Halen (Red Van Halen Guitar), Nigel Maidment (Red roof/Black Vali), Andrew Weyman (Gulf Oil), Branimir Kovac (Vali Silver), John Monmeyer (Maroon/Yellow), Tom Stone (House Auto), Stephan Asseo (Speed Gallery black)...



Middle of Race #2 leading John Monmeyer (Maroon/Yellow) and Andrew Weyman (Gulf Oil) up the Omega...



Me, smiling for the camera, while Brad Roberts does all of the work! (he's reviewing data to help me find some add'l speed)...

The fuel injectors are out (what a PITA that task is!!). The passenger side was easy but the driver's side is blocked by the air intake. With a bit of work, I got them out.

I dropped them off to a local shop for cleaning and testing this morning. They said that they didn't have a lot of work due to the holidays so they would be ready on Tuesday. $24 each.

Always good to do, I bet your idle will improve.

Ok, with the holidays behind me, I finally had some time to edit some video!

This is Race 1 with the POC from December. As usual, full screen HD with sound is the best experience.

The #321 changed his number to #9 so the I call the blue (Gulf livery) car #321 throughout the video when I should have said #9. My apologies to the driver of the #9, Andrew Weyman.

If you remember, the gauge would never go above 3/4 even when the tank was full but would work normally between 3/4 to empty. Then the gauge stuck at 3/4 so I couldn't live with it any longer.

I've replaced the sending unit, made sure that the lines aren't interfering with the float, had the sender/gauge re-calibrated, checked the wiring from the sender to the gauge, verified that the sender is indeed sending the proper signal, and manually commanded the gauge using a tester - and the gauge is still stuck at 3/4.

This made racing last weekend quite interesting because I never really knew how much gas was in the tank except when I filled up completely. After the first race, I filled up completely with 7 gallons meaning that I finished the race with about a 1/2 tank or 60+ lbs heavier than I should have been.

The shop's conclusion this week is that the gauge itself has failed. A local instrument repair shop wanted $750 to repair the fuel gauge. Seemed like a pretty high price, I mean, that's almost a new set of tires to replace a circuit board (and yes, I value every financial transaction in equivalent sets of new racing tires these days). I declined their repair offer and ordered a used instrument cluster from eBay for $99 (including shipping).

Sure hope this solves the problem. I'll let you know what happens when I get the replacement cluster next week.
Did you solve this? This problem is caused by your fuel pump being rotated incorrectly and blocking the fuel level float. There is an arrow at the top of the housing showing the correct orientation.

Thanks for the info! I have not solved it yet. I have a replacement gauge cluster to see if that is the problem. I should have time to get to it this week so stand by for updates...

Thanks, glad that you enjoyed it Mike; the race was a lot of fun.

I wish that there was a way to communicate the level of intensity that is required to drive that close (even for a 30 min sprint race). Its mentally exhausting and physically taxing.

But still the most fun I can have with clothes on.
