Title: V6 Multiram operation
Post by: Marks DTM Calib on 25 July 2006, 16:09:36
Following numerous questions about multiram, I have taken the decision to load the V6 Vaux college files on for all to see:

The multiram does a VERY good job of flattening out the torque curve and hence aiding economy.  
 
You need to consider that for optimum torque you need high air speed in the inlet........so if the inlet is small and long you get high inlet airspeed at low revs but a restriction at high revs (good bottom end torque but nothing higher in the rev range), if its short and large you get low inlet air speed at low revs and good inlet air speed at high revs (no bottom end torque)......the multiram allows a good compromise on both i.e. high air speed at low revs and high air speed with low restriction at high revs.....its a dam good system.
