The drop in is still adequate for your mods. Any reason you're getting rid of it?

 

just for a little more power...and im looking into getting some intercooler piping as well...and alot doesnt really fit with the stock airbox?

 

Hi guys I just bought my Evo so I'm new to tuning it obviously. However I've been curious as to why people don't use cold air intakes on their Evo's. Granted I realize you have to worry about hydro-lock from standing water but honestly how rare is that and AEM makes a bypass valve that actually is proven to work. I've done a bit of research because I'm ready to start tuning it. I figured since JRod is posting back and forth he could chime in? I've heard nothing but great things about Buschur's parts and service so I think I'm going down the same road as you guys

 

It would be minimal honestly. One of the Dynoflash tunes we use is good for another 25-30whp on its own. Not bad power for only $375.

Our turboback exhaust is also good for another 25-30whp.

 

We have made a couple cold air systems for employee cars here including David's 9sec RS. The fact that you do not see more is mainly the fact that there is no easy way to run them without modifying the car a little.

David's RS intake fits well because it doesnt have the intercoller sprayer bottle or HID's. Trent ran one on his car for awhile with HID's but he had to grind out the hole where the intercooler sprayer bottle used to be for it to fit behind the HID.

The short ram design is not a bad design. We all know heat rises so alot of the engine bay heat goes out through the vent in the hood. I know there is still heat in the engine bay. Some customers will leave the "air scoop" that used to go into the air box attached for more air flow into the engine bay to help with that.

Take care!

 

Question, what do you do with the hose from the stock boost solenoid that routes back into the intake piping if you prefer to use the ECU to control boost?

 

Just let it dump into the air the amount is so negligible it wouldn't ever affect intake readings.

 

If all you do is route the line to a catch can vs. a filter, the only difference you are making is keeping a little oil from dripping in your engine bay.

NEITHER of these is the best/proper way to run it. The nipple on the stock intake tube is there for a reason. Under boost it creates a negative pressure in that line and sucks gasses out of the valve cover. With the Buschur intake tube you need to drill and tap a hole to install a nipple so you can keep this system intact.

Some people will run a catch can in line here. The hose comes off the head, goes to the can, then from the can to the nipple on the intake pipe.

jrod what do u think about that? is that needed to be done? because im looking to purchase the BR intake.

After looking under the hood this morning I now understand exactly what your taking about. thanks for the reply. I actually just heard a sound clip on youtube of the intake and it sounds great but most importantly all you guys seem very happy with the performance. I just ordered mine!!!

 

I can answer that for you. He will say no, it is not needed . . .

I disagree. The Mitsu engineers put it there for a distinct reason . . .

 

I do not agree with this. The stock air box is still a restriction hands down.

Take a look here: https://www.evolutionm.net/forums/sh...ht=airbox+test

We also tested the stock air box with a K&N drop in Vs our air filter kit and our kit prevailed. The stock airbox still lacked power and didnt show much better results than with the stock filter in place.


It will not work with the stock airbox. The difference in the routing of the plumbing will not work with the stock airbox due to the location that it is ran. Sorry....

You do not have to drill and tap a hole because a nipple is NOT needed.

It is always a good idea for the over flow oil to be sucked into your turbo and interooler.


No it is not needed! To be totally honest.... I took the stock hose, cut it and pointed it down at the ground so it would drain out of the bottom of the car. I ran my car like that for as long as I can remember with no issues. The amount that comes out is so minimal that it does NOT get on the underside of the car. You can use a catch can if you like but I think the filter or open hose would be your best choice unless you want to spend $100+ on a shiny can that doesnt really fit anywhere under the hood.


Anytime!

Thanks for the order.


Of course you would disagree.....

You think everything that is factory is right? If everything was right from the factory then no one would be making aftermarket parts.

The reason we did not do the recirculation line back into the intake is due to all of the FMIC's we removed that needed to be cleaned before going back on because they were caked with oil inside.

 

It is surprising to once again see evolutionary in here with his odd ball ideas.

I would think of all the people on these forums, you evolutionary, would know that having that hose hooked up to the MAF pipe is a **** poor idea. I distictly remember you paying us to remove your intercooler and having us clean it because your IAT's were high as hell, I also remember this cleaning helping out a lot. As a matter of fact I did an entire thread on it here on EVOm somewhere because of your car.

So, yes the Mitsubishi engineers did the recirculation of the hose for a reason, it is the same reason they did the boost control seloniod hose back into that pipe. Obviously you don't know why, so I will tell you. Emmissions. They are not allowed to dump the oil onto the ground or vent anything externally.

Thanks once again for jumping in with your remarks. This time it is a bit surprising as you know better than to suck all that oil into an intercooler, or atleast I thought you learned SOMETHING from us.......

 

Not to get too far off topic but I did a search and found the thread to back up what I am saying, not that I should have to.

Here is the link to the thread:

What's funny to me now is reading the first paragraph about the customer/friend, boy do things change.

 

Shouldn't be surprising - I am an oddball!

I did learn from past experience. That's why I have that line coming from the cam cover routed to a Saikou Michi dual catch can and then to the nipple on the stock intake tube. Your thread about oil-soak degrading intercooler performance is absolutely right.

Just sharing my thoughts with a member on an open forum. I think it's good for consumers to get as many opinions as possible on any given topic, then use those to decide which path to follow. I'm sure many people will not follow my advice, but that's OK with me.

See FourDoor's thread for what I've based my opinion on. . .
