What should 1000sdi compression be @5000'

[nippy]

What should an 05 summit/Mach z 1000sdi motor have for cranking compression at 5000ft elevation?

I have one that is 115/120psi

Thanks,

Mike

seems a little low, but mine is only has 12:1 domes and its a summit, so they are pretty generous. doesnt seem to bad in my mind... my 13.7:1 mod at 7200 made around 130, but the much lower comp ratio does cut down a bit.

if its a mach, i bet they have even lower comp heads for less elevation.
