This week, I tested Accusump operation for the first time and all went pretty much as expected. Testing consisted of:
a) the accumulator’s ability to ‘rapid fill’,
b) the accumulator’s ability to pre-oil the engine, and
c) a drive of about 30 miles to ensure no leaks.
During a cold start (oil temperature at ambient) the oil pressure of my LS6 is 55-60 psi at idle. After warm up, idle oil pressure is approximately 50 psi. With an engine oil pressure of 50 psi and an accumulator pre-charge of 10 psi, the accumulator filled with approximately 2.5 qts. During accumulator engine oiling (engine off/simulated loss of oil pressure below 35-40 psi), the Accusump system kept the 20 psi low oil pressure warning light out for approximately 58 seconds. Rapid refilling of the accumulator back to 50 psi took around 8 seconds. While I'm satisfied with the results, the ultimate test will be on track.
