Well after a long crazy week I was able to still complete the dyno with a 2004 taurus motor and cams. I brought 4 intakes I dynoed the manifolds in this order mazda6(escape) UIM, 2004 Taurus UIM, 2001 Taurus UIM, then the SVT UIM
The dyno spark inducer was spiking here and there but it just made the graph peaky in some areas. The numbers posted on the mazda6(escape) had no spikes so the numbers were dead accurate now the rest had some small spike so the max numbers were inflated some so if you look at the graph and draw a smooth curve you will see that the mazda 6 defeated the manifold overall except for torque. but power delivery seemed better. The mazda6 and the SVT kept pulling power up top but the SVT lacked alot of midrange power which hurt its numbers. I am agreeing with the fact that the velocity in the manifold is to low on the SVT to large for midrnage power. The taurus 2001 was only overall not to bad of a swap if you are using high lift cams. Now I am going to build another 2004 taurus motor with SVT cams and allow the intakes to be tested up top more. The taurus cams still performed better up top on the mazda6 so the tuarus 2004 manifold starts to fall off where you will notice the mazda6 still had more room for power.
Now looking at the manifold visually me and Mark were dead-on on the predictions about the escape being the better flowing setup between the oval ports up top. The taurus 2004 swap is a very good swap recommended for NA but if you want to get more I am sure you will see the SVT cams or even SE cams work better on the escape manifold. The A/f were low 13's and I didn't touch the it once I tweaked the MAF but the SVT was richer for some reason so I had to readjust the A/F to make it leaner to compare head-up. Now i did do a time pull and the mazda did it 2 secs faster to 116mph but it started 200rpms later so I would take a second off the time if we are comparing the time portion.
