Here what I have so far....
You can see in it that around 5000- something went wrong.
hp just flat lined, and the hp curve never got past the torque curve...
you can also see that the torque curve also turns down and falters.
So with the curves stunted we got 563 rwhp and 604 ft/lbs of tq. on 9 psi--- and there's
a lot more hp left at that Psi level. If we hit it with 9 I'll leave it at 9.
We were wondering what went wrong, as extra timing, or more boost had no change...
As we couldn't fix the anomaly. The boost controller was set first at 10 psi and then 12 psi, but we would never see higher than 9 psi.
After taking it back to Accufab the culprit was the valve lift,
as the pressure inside the motors was lifting the valves off
and letting the boost out at 9 psi.
Now with the new valve springs installed we should see the finishing of
the torque curve and hp curve that rises above the torque line...
Plus with everything running right will push it to 6500 rpm instead of letting off at 6000 rpm.
