Test Overview

As a follow up to our recent Evo 8 & 9 testing (http://www.mitsustyle.com/forums/showthread.php?t=29169) 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 (http://www.maperformance.com/map-short-runner-tubular-stock-replacement-exhaust-manifold-mitsubishi-evo-x-map-evox-em.html)

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 (http://www.maperformance.com/maperformance-tubular-exhaust-manifold-evo-x-map-evox-tem.html)

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 :)

I don't think I need to comment my modlist on this site but I will on the other forums. Unless you want me to Chris.

I think we got it.

pictures of the revised manifold please!

I figured as much ;) Exactly why i didn't post anything.

Post it, I am sure not everyone has your mod list memorized. Copy/paste is easy ;)

Great results! Im sure Dave is Happy!

550whp DD tune that's so legit!

Great results, thank you for sharing! Boost curves look closer than dave had described, that is definitely a key aspect to this kind of testing. Dave sent me a bunch of the logs and timing looked identical across the first round he sent, I have yet to review the second round.

Pumped to see the MAP Rev2 tubular mani make its way into production, and as always more data is good data imho.

^Like I said the boost curves I posted were just one run randomly from each to give an idea. There were definitely runs where boost was much closer.
