EVO X Intake Manifold

evojanoy · Nov 1, 2008, 07:32 PM

Does anyone know when someone is going to put out an intake manifold for the Evo X

I think the stock is pretty good...I dont think any manufacturers have any plans to make one, wouldnt be enough interest.

Not so sure about that.....factory parts are a balance of cost vs. performance. I'm sure AMS, Indy, Magnus, etc. would like to see what they could do from scratch...

Im sure they would see gains if the engineered something really nice, but im also sure it would cost a a decent amount...I dunno...i just dont think they would stand to make a profit from making it unless it was super cheap and had great performance. but those two things do not go together.

I guess it would also be cost vs performance. I'm going to see if I can get a custom one made I'll post it when its done. The guys at ISS Performance made one for an evo 9 that was sick. I'll see if I get Dyno Sheets for it too.

I got one in develpment now. I don't think about the cost effectivenes but the guys whoaa doing mine says he'll cut me a deal 4 it s a prototype but as far as performance aspect of it I'm sure der will be some gain but overall I feel better knowing dat I have something that not a lot of people have and if the result s what I have hoped for then it wud not take much 2 sell it @ cost but pics and dyno 2 come.

I know that Jun has a modified stock intake manifold. It looks pretty sweet but as you can guess, its pricey.

Getting the stock intake manifold extrude honed might be another option, I would imagine it would cost about $500 range to get that done. It basically smooths out all the ports and makes them all slightly larger where it counts for improved flow.

Quote:

Extrude Hone uses advanced surface finishing solutions, to remove rough cast surfaces that restrict horsepower efficiency of racing/performance components. By enlarging and uniformly polishing internal air and fluid passages, flow velocity is maximized.

Superior results are reflected in the widespread use of Extrude Hone Powerflow by professional race teams in NASCAR, NHRA, IRL, CART and SCCA. In addition to meeting the rigid requirements of professional race teams and production automotive manufacturers, Powerflow is an effective process for the performance enthusiast. Increased custom airflow can be tailored specifically for a Powerflow application. Results have demonstrated that such increases can exceed 30 percent on aluminum intake manifolds and 25 percent on cylinder heads.

Level I PROCESSING $545
Includes a thorough processing and inspection of your part to provide a linear surface finish to maximize airflow.

LEVEL II PROCESSING $635
Includes hand-blending to specific gasket size prior to Level I processing. Automotive heads, intakes & exhaust manifolds only.

Found that site where you can send your parts in, not sure if any official Evo vendors can do it for less as they mention discounts on group buys but it sounds like a viable option. Likely I would port match mine prior to sending it in and just get the Level I processing. I did get this done on my 96 Eclipse GSX and it seemed to help mid to upper Rpm airflow.

With multiple runs and solid datalogging I think we can measure before and after results pretty accurately using this Dyno Simulator and overlay the graphs for spool times etc:

Virtual Dyno Room-Dyno Simulator

I could stand to trade some spool for engine flow as 3600-4000 RPM's above 20 psi I get compressor surge in 5th gear. I can drive around it by letting off slightly and reducing boost until it's out of that range but I would rather be able to mash the throttle in all gears.

ops:

Extrude Honed Stock Intake Manifold: $545 + round trip shipping (est 10whp-15whp gains, should be no torque loss on low end)

Blitz Intake Manifold for Mitsubishi Lancer Evo X: $1800+ JDM YO! (est 10-15 whp with decent torque gains) - Increases manifold volume from 1.4 L to 2.8 L, haven't seen dyno tests state side yet.

GrimmSpeed PnP Intake Manifold EVO X:$160 ($260 coated) (Looks like they are doing a basic port and polish on the ports, not sure how far they can get in without splitting it open.

MAPerformance CNC Ported Intake Manifold Evo X [Rev3]: $650 ($740 coated) (has some great baseline and modified CFM flow numbers and seems like the best bet so far unless extrude honing ends up beating it out. They even split the manifold open for porting then weld it back together.)

These guys have an insulating gasket, not sure about the claims for power are even close but it would be worth the $68 to reduce heat soak and likely be worth around 5 whp.

I'm still deciding what the best course is but the MAPerformance option looks solid if they could just release some dyno numbers on an upgraded turbo setup. Has anyone upgraded their intake manifold and want to share some before and after results? What about Magnus, anything in the works from them?

Stock is fine, i have no problems with it

Hiboost · Jul 1, 2009, 09:45 AM

The design might be fine but if you have seen one in person and looked at the runner sizes and plenum volume you would see that upgraded turbos might benefit from a higher flow setup. Gaining horsepower under the curve is never a bad thing especially if you can get it across most of the RPM range.

tenevoten · Jul 1, 2009, 12:37 PM

i would like to see some after market manifolds done up.

antics22 · Jul 1, 2009, 02:31 PM

Blitz has one too.. The few that are out are from JDM companies as far as I know. I think you would only benefit if you are running a larger turbo.

MAP Introduces New Ported Evo X Intake Manifolds!

ChrisCarey · Jul 3, 2009, 09:44 AM

Thanks for the kind words guys! As has been stated above the OEM intake manifold is better than expected, but can definitely be improved upon

If there is anyone out that with an upgraded turbocharger that could do some before and after dyno testing for our Rev3 please don't hesitate to contact me for some special pricing!
