MAP's Evo X Exhaust Manifold Testing / Dyno Results

[v8klla]

Test Overview

As a follow up to our recent Evo 8 & 9 testing we decided to bring in another car and test a few exhaust manifold upgrades that we offer for the Evo X platform I do not know the ins and outs of this car (perhaps Dave can chime in) but I do know that its on E85 and sports an FP Black with supporting mods. We used Dave's more conservative street tune for the testing, keep in mind that no changes to the tune / boost level / etc. were made during this testing so those numbers do fluctuate a little bit. It's also important to note that the baseline here is an MAP ported stock manifold, enjoy!



MAP Ported Exhaust Manifold vs. MAP "Short Runner" Exhaust Manifold

Boost was a touch higher between 4500-5500, but there were substantial gains throughout the power band! As you can see it spools a little slower but power output is very similar during spool up. +26whp & +13ft/lbs over our ported stock manifold for just $569.99 shipped? I think we had better place another stocking order!





MAP Ported Exhaust Manifold vs. MAP Tubular Exhaust Manifold for Evo X

Our in-house fabricated tubular manifold performed admirably with peak gains of 24whp & 18ft/lbs over the ported stock manifold, but we were surprised to say the least that it came in 10whp less peak than the short runner above (although the short runner appears to have been at a higher boost level when it achieved peak whp). We decided to make a revision to the routing of one of the runners and were pleasantly surprised by the results as gains up to +33whp & +26ft/lbs were realized Needless to say this revision will now be permanent.







MAP Ported Exhaust Manifold vs. FID Tubular Exhaust Manifold

In response to recent testing done by one of our competitors (and due to the fact that I wanted to see this with my own two eyes) we took it upon ourselves to order up an FID manifold and perform another comparison in house. Below you will find a comparison to the MAP ported stock manifold and then our revised MAP tubular manifold. Absolutely nothing was changed in regards to tune, in fact no MAP employee touched a laptop while in or around this vehicle (the owner logged the runs). Even with that being said I'm certain there will still be those that doubt the legitimacy of this testing, hate on haters as I saw what I needed to see
