Jetting Adjustment for Sea Level ?

Aubrey N Bruneau · 05-13-2009, 08:44 PM

I imagine that this is probably pretty mundane stuff for most of the guys here

My car runs a pair of 1405 Edelbrock AFB's ( 600 CFM )
We tuned on the dyno in Calagary ( 3500 ft... actually measured 4000 on the barometer )
Current jetting is 92's on all 8 corners, using 7552 metering rods.

Need to make appropriate "enrichment" for sea level.
I don' have the equipment or experience to make the fine tuned changes there, so I need to get a safe, but power making mixture.
It will take no leaner here, as it is.

I'm thinking of bumping up to 95's in the secondaries, and dropping to a 7347 metering rod in the primaries.
Not sure if that's enough though ??

hope you guys can help ?
