And the answer is... Roots. Because the area under the torque curve is much larger. The rotrex only has a very small chance, and this if it manages to stay all the time close to red line. You can use the power smart in a roots, a gear up than the rotrex and it still has better acceleration.
Also the Rotrex has to be in high rpm all the time, and the Tritec engine isnt really made for this type of use, not matter if some of us are reving it a lot. Watch your oil pressure gauge after 6.5k rpm.
