Golden's 2010 Evo GSR

[Golden]

Whats in store for my X in 2010? Well here is a list of the parts headed my way.

Cobb AP
Megan Boost Guage (used but well loved for by Scott)
Forge BOV
Forge Wastgate Actuator with 19-24 psi spring
Perrin 3 Port EBCS
ETS 4" FMIC
TurboXS full turbo back with test pipe

And I'll button it all up with a Road Trip down to Kansas City to Modified by KC to get her dyno tuned. I hear nothing but good things about these guys, and I can't wait to see the shop.

So, here are my thoughts on how / why I put this all together. I've already changed out the intake to breath better and replaced the UICP to hold boost better. So continuing down the intake path, I will install a new 4" ETS FMIC. This should keep the intake charge nice and cool no matter how hot it gets. Everybody has nothing but good things to say about ETS's ICs for the X. The stock IC on the X sucks ass. It's tiny and restrictive. Lastly, before the intake charge hits the engine it flow through the LICP. The stock pipe is good on the X, so I am choosing to leave it alone.

Now how will I control this newly cooled and contained boost? I purchased a new Wastegate Actuator from Forge that has a 19-24 psi spring on it. The stock wastegate actuator is rated for around 11 psi. The design of the X's turbo allows exhaust gases to slam into the wastegate and force it open. The stock 11 psi spring just doesn't cut it. Will this increase my peak hp / tq levels? No. It should give me better mid range power and a flatter torque curve. Theoretically it should hold boost all the way to red line, and if I had an upgraded turbo, it would. But alas, the stock turbo runs out of air around 5500 rpm and boost levels start to drop. Now the new Actuator can't do this all on its own. If left up to the ECU, it may be forced to open during spool up and mid rpm ranges. In steps the Perrin 3 Port EBCS to help out. With the 3 port, the ECU will still control boost, but it won't be via a bleed setup but rather with an actual on / off controler. The 3 port will help spool-up happen earlier and make a more responsive turbo. Both the Wastegate Actuator and the 3 port require a tune. They will both cause over boosting. The wastegate actuator will need a tune because it takes more pressure to open it now, and the 3 port does because it will keep boost from hitting the actuator.

Continuing down my flow, the charged air hits the cylinders and gets a good dose of fuel, ignites and flows out the exhaust side. From here it will travel through the turbo and into the bell mouth. Here is where the TurboXS exhaust steps in and frees up the rest of the way. The new exhaust should allow the turbo to spool better and breathe better at higher rpm's.

What will I get form all this? I'm fairly confident that I should see the 350 / 350 mark on the dyno. But the numbers won't be equal like that, the torque number will be higher, so maybe 350 / 365. She should spool nice and low, in the 3000 rpm range. Right now, I'm just looking for a fun street car, and low end torque will get me there.


Oh and lets not forget, I have me a can of paint that's just itching to cover up the chrome on my side mirrors. They are UGLY. A new satin black finish will do them quite well. Also on the coloring block is the chrome that surrounds the trunk release button.

why not powder coat the wheels?

This is what going to happen. Parts already ordered.

Rims may get changed out. New ones may get purchased. Springs may get ordered. Not sure. I am getting married in October, so I'm supposed to be saving for the honeymoon. Once this wave of upgrades are in, I might just have to live with the rims I have. I might just rattle can them gun metal. You never know.

[LancerXI1]

true gl!

Michael, a customer of mine with an X put down 350awhp on the following mods.

Cobb AP
AEM Induction box
AGP Full hardpipe kit
Megan Catback
ETS 3.5 inch FMIC

You'll have a few extra goods tacked on beyond his. Therefore I believe bet you'll get 10-20awhp over your guestimation! I'm excited for ya!

Man looks good so far and can't wait to see her when you get done. I hope Jordan is right and you get some good power out of that beast.

Tonight I was driving in the super cold weather here, and my car was barely warmed up. The cold engine coupled with the cold air temperatures ( 0*f ), the exhaust was making a good vapor cloud behind me. This was the first time I was able to get a glimpse of the aerodynamics of the car. Since I first laid eyes on the X in person, I've always wondered if the spoiler actually works, as most spoilers on the market do pretty much nothing. In order for a spoiler to work properly, you need to get as much air under the spoiler as possible. The faster moving air under the spoiler is less dense and therefore causes the denser air above it to push down on the spoiler. This is the opposite of what an airplane wing does. So, back to my story, I was able to see how the air was coming off my roof and through my spoiler into the vapor cloud behind me. You could definitely tell that a large amount of air was flowing under the spoiler and pushing the vapor cloud away. This makes me very happy, and I am now a believer in the spoiler.

Which leads me to other thoughts I've had about the aerodynamics of the car. Roof vortex generators are not needed on the X, because the convergence of the air seems to be in the right spot. It seems that Mitsubishi designed the aero package right, but in their defense, wind tunnels are very common now compared to back in 2002 or earlier when they were developing the 8's aero package (which the 9 has).

Upon inspection of the spoiler, it should cause very little drag in the air stream. I figure roughly 2-3 times more drag than the side mirrors cause. Only the thin portion of the spoiler has to hit the air stream, but most of the air coming off the roof is directed under the spoiler. This is free downforce. I highly doubt that removing it would improve the aero package enough to change cruise mpg. I might even test this when summer hits.

Look what I found at the store tonight. I'm always glancing through the Hot Wheels just to see what they have. I love the fact that I now own a car that is made into a hot wheel.

I did buy 2 of these, just for the fun of it, but it will be the 3rd Evo X hot wheel that I will have. The first is a color change one that my girl got me for xmas. The second is the one I should be getting shortly from the raffle. It puts a big fat grin on my face.

[Golden]

Side note: The driod sure does take some shitty pics. But it is nice to be able to take a pic and upload it directly to photobucket.

[FreshandClean]

Pow pow powerwheels.

[DenverEvo]

I have a EVO VIII X-Mod around here somewhere that is pretty fun too!

Gas milage does not change I've tryed it.Just to see what it would do, it looks pretty good but it also looks good with it on, and it works hittin corners hard in the canyons it helped me straighten out faster.

[Golden]

That is good to hear, but I still may try it wingless. My only concern is having a safe place to store the spoiler.

[HEISS X]

No shit, it's very expensive.

[RallyEclipse98]

That's actually a good looking hot wheel car.

You can't just hang the spoiler in the garage away from anyone's reach?

[Golden]

I could. My ceiling is finnished and the walls are cinder block. But I could figure something out.

[DenverEvo]

I keep my wing in the crawl space.

[DenverEvo]

Probably shouldn't........but I do.

[RallyEclipse98]

I have my stock wing under my pool table. Now you have an excuse to get a pool table if you don't have one already! There, problem solved!

[Golden]

Sweet! That is the best idea yet. But... she is having a hard time accepting all the parts I've been getting.

You aren't married yet, are you?

JK!

[Golden]

Nope! And lots of these parts aren't being brought to her attention.

[aftershock141]

My trunk is in my basement. Hopefully it doesn't get ruined. I need to build something to set it on and keep it in my storage locker so it doesn't get ruined. I've already caught my cat trying to "love" it by rubbing on it.

[HEISS X]

That's a good idea,I never thought about putting stuff under my pool table.

[Golden]

Here is the Evo X Hot Wheel that my girl got me for xmas.

[Golden]

Look what came via UPS yesterday:






It's smaller then I thought it would be, but still, it's super cool.

My parts list has been slightly modified. The ETS 4" FMIC is out of stock and 4 weeks back ordered, so I had to choose a new one. The ETS 3.5" core was in stock, but I decided on the Perrin. I ended up getting the Perrin for a tad more than the ETS, which is a good deal. The Perrin has cast end tanks, is .75" wider and 3.625" thick.

An intercooler is not ground breaking at all, but our core is different and made to a level different than the competition. When we built our core, we made it as big as possible (not going to 4" thick which is a bit too thick in our opinion) and still using the FULL opening in the bumper. 4" Intercoolers do work, but the downfall is the thicker it gets the less effective it gets. Given 2 cores with the same volume, a thinner core that is bigger in all ambient directions is better than a super thick one that is smaller on the ambient side.

Our size of core is
PERRIN 20.75" x 12.375" x 3.625" = 930 cu-in Ambient cu-in 256cu-in
Brand-1 18" x 12" x 4" = 864 cu-in Ambient cu-in 216cu-in
Brand-2 20" x 12.4" x 3.625" = 899 cu-in Ambient cu-in 248cu-in

Size references:
ETS: 20x12x3 Volume:720
ETS: 20x12x3.5 Volume:840
ETS: 20x12x4 Volume:960
The Surface Area of the Face of the ETS is 240 in^2 and the Perrin, as noted above is 256 in^2.

I've been unable to find the size of the stock fmic, but these 2 are way bigger. I think like twice as much volume.

Exhaust came via FedEx.

Still in box:


Unwrapped:


Tips:




First Impressions:
Welds are very nice. I love the tips. One tip has about a quarter inch more blue on it; the perfectionist in me would like them to be identical. One tip was flattened on it's side from FedEx dropping the box. I'm pretty sure I can fix it. The box was fairly heavy and the FedEx driver is female. I thought the main long pipe, the one nobody names, would have a resonator in it. Mine came without. And I just looked at pictures online, and I was totally thinking of something else, as no pictures of this exhaust ever show a resonator in there. I hope it doesn't drone or else I may have to have one welded in there.
I'm very excited to get this on, but I'm not sure if it will run too lean. I might do the cat back first, as that shouldn't affect the flow too much, but it won't really add power either. I probably need a wideband.

[Coqui]

Man, browsing thru some of these threads makes me want an evo even more! One more deployment should help me get out of all my debt except STi and then I'll have room to own an evo along with STi

[HEISS X]

The ap is bad ass,just make sure you get it tuned for what you have,don't go off of what Cobb says for stage 2,it does'nt work I over boost all the time and I have everthing that is required for stage 2.
