Re: MAP Introduces New Ported Evo X Intake Manifolds!

Flow Test Results: Rev3

We have a lot of time invested in the research and development of our intake manifold work, and the EVO X platform is no different. {thumbup} We strive to always bring the best solutions to market, and we think we have done exactly that with this manifold work! We started off with an unmodified manifold and flow tested it for our baseline. Then after our porting guru did his thing we had it flow tested again and the results speak for themselves

For starters, this manifold appeared to have a very solid design for an OEM intake manifold. Tapered plenum, decent sized runners, radiused runner entries, and fairly uniform runners as well. We did expect to pickup a few CFM from the work but when we went from 1187CFM total to 1267CFM total AND were able to balance the manifold so that 3 runners were exactly the same and the other just 5cfm behind.... we knew we had something good. For reference, our ported Rev3 intake manifold we offer for the Evo 8/9 had less CFM gain overall, and not nearly as balanced runners, but was still good for 40+ whp on a big turbo Just imagine what this manifold will do once we are able to put some serious CFM through it!

We will be posting more results shortly, but for now here is the flow data:



Dyno Test Results: Stock Turbo

This test was performed at 24 psi on a mildly modified Evo X equipped with the stock turbocharger. Unfortunately the RPM pickup on our dyno wasn't functioning properly the day of the testing so we were only able to obtain HP numbers as a function of speed. The gains are about what we expected as the OEM manifold is a solid design right out of the box, however, we feel that the changes we have made in this Rev3 version will really start to shine as more air comes into the equation (ie upgraded turbocharger) much like our testing on the Evo 8/9 platform, those results are coming soon

It is also important to note that spool up characteristics were not adversely affected by the manifold work. In this particular comparison the dyno pull with the modified intake manifold was started at a higher speed thus the appearance of lag.
