Moroso says 6psi. I had about 8-10psi precharge. I will also be testing a higher pre-charge next month when back at Chuck.

Latest lap from around Chuckwalla CCW, little late as it was end of January. No PB's as I think the RE71RS's are about done. This was a lap with the accumulator as well.

Latest lap around Chuckwalla CCW with 86 Cup this past weekend.

New PB and inching closer to the sub-2 point, with a 2:00.683 lap.

Also ran the Moroso accumulator at 20psi pre-charge and it performed much better.

Are you going to try 25-30psi?

Maybe next time, I did 20psi pre-charge and this was the result. Bright purple line with accumulator, dim line without:
