Well, it is not "if an issue will occur on a race track" but rather just a matter of when! Sunday morning was gorgeous at roughly 65 degrees and cloud cover. The grip was surprisingly good and the dense, cool-ish air enabled the engine to run really strong.
The night before, a few of us "walked the track", taking in the nuances that really can only be seen on foot, kneeling down and taking our time. More drivers should take advantage of this to become more familiar with details that are completely missed behind the wheel of a car. Anywho... We were discussing an asphalt patch that is on entry into the downhill section to turn 10a...specifically, how the patch had an elevated center with ramps on either side. A friend mentioned, "hitting that at speed would cause quite the jolt to the car and driver". Also of concern was the potential loss of grip and the unsettling of the chassis at such a critical point. He was correct as I bore out witness the next morning. We have still not found the smoking gun and only hope it is not internal; the top-end is fully functional with each of the valves operation correctly. The engine does not turn over quickly and that obviously is a cause of rather great concern. I have been doing track events for some time now, over 15-years, and have never encountered such a failure. I guess I can say...enjoy the failure at my expense. PS: Talk about cutting it close...lose an engine down the hill; try to jump start the engine at turn 10a and just BARELY make it up the hill over T11 to glide back to the hot pits. Whew - that was close! (IMG:style_emoticons/default/biggrin.gif) Cheers! Tony https://www.youtube.com/watch?v=VRvMJeXJxTQ My son came in from college - great memories at the track with him! |

Jim - I will detail plans to avert the possibility of this occurring again in this manner in the near future as things come together. I am more than content with the OEM equipment despite the limitations that come with it - Motec ain't everything as I have seen many sidelined due to electrical woes - GM invested a whole lot of time and money to ensure their equipment would be reliable. Thanks thought - good ideas for sure! Stay tuned...
D2K - The engine will be completely disassembled, flushed and balanced and blueprinted at one of the nations leading LS shops. It will be very right... (IMG:style_emoticons/default/beerchug.gif) Kent - You're all heart brother... (IMG:style_emoticons/default/biggrin.gif) Tony |

You're certainly right; while the controllers are generally super reliable there is a lot of waste in the form of people buying expensive hardware and handicapping it with poor harnessing and system design. (IMG:style_emoticons/default/blink.gif) The OEM harnessing certainly has that going for it. Interested to see where you go...and glad I'm not footing the bill!
