Intake test results are here

[BurritaSVT]

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.

mazda6 vs 2004 taurus


mazda6 vs SVT


SVT vs 2004 Taurus


notice the graph how the only two intakes that don't fall off are the mazda 6 and the SVT because their ports are larger making the two setup less torque down low and I think the plenum volume is what held the SVT from exceeding all the setup so I will add a larger plenum on the SVT UIM to test for volume checks.

Thanks for all your work Joey.

Will you have the ST220 for the SVT cam tests?

Yes I will line it up with Rara so we can test the two mazda6(escape) against the St220 because honestly after looking at both in person we may have a golden peice the escape we never knew would be better breathing up top than the other oval ports. I really think the ST220 will match up to the mazda(escape) manifold because of the larger ports and bigger plenums.

when you say the mazda6/escape are you talking about the intake that is taller and has shorter runners?

could you post a pic of each of the UIM's just to clarify which is which. I have 3 different 3L uims. Will there be an EH 2.5 in the mix sometime as well?

too bad the mazda 6 wont fit under our hoods. i thought the svt would perform better. i do think it will with the svt cams

I guess the oval ports weren't that bad after all

I remember a couple of verrrrrrrrrry long threads...

Wow very interesting!

[SpookSVT]

Did you readjust the tune for each manifold or use the same tune for all ovals then retune for the SVT?

I await to see the ST220 perform...

Also, I'd like to see the A/F and and spark data for all of the above runs as well as the acceleration graphs. One other thing too, when you add the plenum spacer to the SVT, make sure you measure for acceleration between having one and not. This will be key since the larger volume may very well show little decrease in acceleration time even though it gains power, making it a small net gain. Something that needs to be looked out for...
