so I’m running a lsx 422 12:1 solid roller email@example.com .758-.722 lift 114 separation 112cl cam
ported ls7 Frankenstein heads Holley hi ram intake 102mm tb using Holley dominator Efi.
I’m seeing 90kpa at idle no vacuum leaks that I can find. Fairly stable idle at 13.8 afr My question is does this vacuum sound reasonable? It seems like it’s crazy low
What altitude/baro pressure? What does it read key on before running or if you stall it?
That is a fair bit of cam isn't it? Wouldn't expect it to pull much. Have you played with/confirmed cam timing?
Sea level. Reads 100kpa key on engine off
no I haven’t played with or confirmed cam timing
