With our F355 manifolds repaired and a recent minor service we redynoed our car to get accurate baseline numbers. Edit -Run 2 is fully stock -Run 1 is with the exhaust valve wired open. Image Unavailable, Please Login
I think the chart would be more useful (comparing the exhaust valve function) by showing the hp and torque numbers from 2k to 5k.
Agree. That is the range which the valve was designed to effect. For most of the graph the valve is supposed to be open anyway.
