Brief 5M Question

854 Views 5 Replies 6 Participants Last post by  SilverMk2
I suppose this is where to put it :roll: . Why does the 5M run out of power at about 5400 rpm. Is it just a lack of fuel, or something else? The reason is a couple of us were tossing around the idea of trying a SAFC (Megasquirt since we're broke) on one to get it to make power up to 6K or maybe even 6500. Any thoughts?

I've yet to see 5 or 6M, even with all the mods, not see a drop in power on the dyno by 6500 RPM. Most of them peak from 5500-5800 RPM. I think my car peaked at close to 6k with the cams in it, and a few hundred RPMs lower seat of the pants without. Usually the reason you see this is because of what the head will flow combined with the cam timing.
