MAP's Evo X Exhaust Manifold Testing / Dyno Results
http://www.maperformance.com/img/forums/evom-header.jpg http://www.maperformance.com/img/forums/tb-maprace.pnghttp://www.maperformance.com/img/forums/tb-whymap.pnghttp://www.maperformance.com/img/forums/tb-services.pnghttp://www.maperformance.com/img/for...-clearance.pnghttp://www.maperformance.com/img/for...-customers.png http://www.maperformance.com/img/forums/sep.png 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! http://www.maperformance.com/img/forums/sep3.png 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! http://www.maperformance.com/img/Por...SMAPShort2.jpg http://www.maperformance.com/img/forums/sep3.png 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. http://www.maperformance.com/img/Por...APTubular2.jpg http://www.maperformance.com/img/Por...edTubular2.jpg http://www.maperformance.com/img/forums/sep3.png Conclusions The results from the short runner were surprising to say the least. Ultimately I think our revised long runner will yield the biggest top end gains and its built like a brick, but its hard to overlook the value in that short runner! Also, we did a little more testing in response to a recent competitor's post that isn't included in this thread for political reasons, the only comment I will make regarding that is that I am confident our tubular manifold is the absolute best performing unit on the market :) http://www.maperformance.com/img/forums/sep2.png |
wow great results! another set of quality products from you guys. Kudos!

I sat in the passenger seat while Jordan drove for all the testing and have logs for everything if anyone has doubts. Thanks MAP for the opportunity, it was fun! |
Have anything comparing the stock manifold to the short runner? I'm assuming the short runner vs. tubular would be for someone looking for quicker spool, like me?

1. Are there any dyno results for stock OEM exhaust manifold vs. posted OEM? I think that would be of interest to loads of folks here. Preferably with a less "built" car on pump gas, pls.
2. Who makes the short runner for MAP? The layout looks similar to the Tomioka that you also sell and to a number of designs for sale on ebay Great testing results! To be frank, it looks like the short runner at high RPMs is showing stronger gains than the full length manifold? Thanks for sharing. |
Wow, great numbers.

what boost controller are you using?
|
CAn you use a tubi Manila for a stock turbo and get good results?
|
Yup... the one thing that's missing - and hard to account for in these comparison - is the ideal tune for each manifold.
Kudos to MAP for these comparisons.

It's also running more boost if you look at it. It's a very very strong mani, but the longer runnered mani's will show better topend when fully tuned I think.

nice to see the effort to improve your product.

Don't forget about me... is the short runner more for quicker spool vs. the longer tubular?

Nice results. Def going on the future parts list lol
