ng900 Turbo enduro updates
Last post, the car was prepped and ready to race, but the next few races were overbooked and it didn't get in. It went to a couple of track days for shakedown, where a cracked turbo water hardline and leaky valve cover gasket manifested themselves.
No big deal, fixed those. Less expected, my teammate had the hood fly up and hit the windshield.
(Looking for a picture still.)
Upgraded the t5 "companion laptop" to a solid state drive for vibration resistance and incidentally a nice speedup.
Added a passenger seat for track day use.
Painted the rest of the car the same navy blue color I'd given the roof in the last installment.
We all know stripes add horsepower. Lots of stripes must make a car REALLY fast.
Notice the hood is dented, that's from the windshield incident.
White number panels with silver borders.
Yellow badges, gas cap, grill and wheels.
And lastly, easily removable plasti-dip numbers. Plasti-dip is the new vinyl. This is it in full race trim.
With the car looking good, sounding good, handling better than ever and seeming mechanically sound, it went to Thunderhill for its third lemons race.
And after 7 hours, the engine lost power and proved later to have eaten itself. Bad knock from the timing-side of the engine, either a rod or oil pump or something in that region. I know oil pump failure is known issue on the b204 when it gets old and tired, so that's my guess for now until I get to the teardown.
Sigh. Junkyard engines, am I right? Next time I'm building a fresh one instead. At least the electric cooling system performed flawlessly, through the shakedown days and the race.
One of the drivers runs a photo blog and took some nice pictures of the car in (and out of) action.
Doppler Photo: It wasn't supposed to end this way… again…
(Only correction is that it was the starter, not the transmission, that separated.)
