stocker low lift flow

Adger Smith · 03-02-2013, 05:35 PM

I'm with Mike on the average flow. I've had engines pick up big time when I change the valve job to one that provides a fatter bell shaped flow curve.By big time I mean in the operational torque curve. I would much rather see a flow curve that was way fat at low & mid lift than one that was a few points higher at peak and was linear. If you can do that you are usually going to see more tq and better down track performance, esp pulling off a gear change & hitting the converter leaving the line.
Now leave the seat angles you have on it alone and go to work on the shape of the valve, esp at the margin. Watch what happens!! :~)
