Pure Tuning Tests Skunk2 Intake Manifold and Throttle Body for Evo VIII & IX

So a couple months ago I get a call from a friend telling me he’s gonna give his 05 Evo a little update in the power department and at the end of the parts list was the S2 intake manifold.
Uhhh, did I hear a niner in there?  Really, I didn’t even know S2 made a intake manifold for the Evo and we are a Skunk dealer, or maybe I did hear of it, but immediately disregarded it think S2 does Honda’s not Mitu’s.
I have to actually admit I was extremely skeptical the manifold was going to work or work any better than half the others on the market.
Now I definitely wanted to test the manifold and knowing the Mitsu community is picky about their intake manifolds I wanted to make sure the S2 manifold actually worked and where, but there are so many other units out there even if it performed would anyone notice?  Well Evo fans you need to see the results!!!!!

Forge Recirc Valve vs Subaru OE Recirc Valve Dyno Test by Pure Tuning.

We still get Subaru WRX / STI owners today that say “the original equipment turbo recirc valve is adequate for any turbo or boost level so why should I change it”. What a better way to prove if this was true or not then on a stock car.
For this test the valve in question is the Forge Motorsport Recirc valve that sells for around $170. This is a direct bolt on replacement valve that uses the adapter from the OE valve to recirculate the exhaled air back to the induction hose.
The car tested was a bone stock 06 STI with mid 20k on the odometer. Looking at the dynograph you can see the difference in power before peak boost is reached at 3800rpm. The OE valve hangs open a little which is primarily for smooth transition between shifts so where this is great for Granny it’s not what we are after. The Forge valve shuts immediately giving the engine all the boost and air volume as the turbo is providing it. The peak number didn’t change as the target boost is the same but the increase in boost pressure below 3800rpm netted 10whp at 3270rpm and 17ft/lbs at 3300rpm.

That is defiantly usable everyday performance!

This comparison was done to show the difference in the OEM turbo options and a good initial upgrade for the EvoVIII and IX. The CT9A chasssis came with a few different turbo configurations with a large improvement in 2006 with EvoIX the MHI-9-Turbo. Shortly after the 9-Turbo release Forced Performance took it another step furthur by offering their 9-Green Model using the 9-Turbo housings making it a direct bolt-on upgrade.

First things first… The point of reference will be the Magnus Street Intake Manifold (MSIM) which was on the car originally when we finished the new turbo setup. The MSIM had been on the car for 3-4yrs already so we used it for the build

However, we were looking for more on the existing setup and needed a new intake manifold to take better advantage of the turbo and headwork.
