How much power should I make roughly at 6psi

Post by Bungles27 »

Hi everyone was just wondering what sort power I should be making at 6psi I'm new mapping and have made 261bhp at the moment but think that is a bit low for my spec
Was wondering if any one on here has a copy of there fuel and ignition maps at roughly the same boost so I could compare and see if there is any extra bhp to be released
Any help will be great I'm running on mega squirt also

What engine? What "Spec"? Where are those figures you quote from? So many details missing.

TCD mentions 12hp@1psi boost for an m30 (I think) using his hardware. Might be a good baseline figure.

With 6psi and 8:1 CR that seems like decent power, what were you expecting? At 8psi turbod I put down 300hp. Any dyno plots to post? What AFR and spark advance are you running at full load? There are a fair amount of good fueling and timing maps in the MS FAQ thread for reference. The spark advance on a SC engine will be slightly different than that of a turbo engine. A SC engine can better scavenge (clear out hot gasses) and typically will allow a few degrees more advance before becoming knock limited than a turbo engine. Can you post screenshots of your maps?
