Tested v8 e55 w210 m113 dual stage intake manifold,
So I tested my dual stage intake manifold that is sopose to open at higher rpms and direct airflow into shorter runners for higher hp and stays close at lower.
So by visual inspection and by revving the rpms i could see that flap was opening just like it should
I went ahead and did some 0-60 runs tonight with gtech 4.93-5.05 range
I then unplugged the vaccum tube going to the flap to prevent it form opening at higher rpms. Did some 0-60 runs and times were very similar 4.98-5.15 range.
What am I missing here? is there no higher hp benifit? I would of thought that there would be a noticeable difference with dual stage disabled...
