Is a 2" thick intercooler too thin?

[Brian MP5T]

Looks good. Are your pipes 2.5" all around? You have the same turbo as the MSP. Based on my rough calculations the inlet on the turbo is 2.25" correct? And the TB is 2.5"?

Thanks again.

The port on my T-25 is 2" and the Throttle body on the P5 is 2.5"

You might notice that the IC has 2" on 1 side and 2.5" on the other side. It was purchased with this in mind so I did not need to step up to the IC. The intake before the IC is all 2" Aluminum and 2.5 after past the IC. The plumbing scheme was really ****** up. I attacked the task of installing the IC then worried about the plumbing. Custom means "More work" in Latin, I am sure of it...

It's a hard place to see but the MAS is on the pressure side before the two extra fuel injectors...(Red). The BOV is a Turbo X/S RFL. It's right next to the T-25 on the 2". This was done so the car does not stall every time the BOV opens. Ask if you need a better explanation..


Later...Brian

The IC I bought has an inlet/outlet of 2.5" I'll just get one reducer that's all. I was going to put my BOV on the TB side about 10" away from the TB. So you're saying that if you put the BOV on the turbo---->IC pipe the car won't stall with a MAFS? When you say MAS do you mean MAF, because that device before the extra injectors looks like a MAFS to me. Your setup looks beautiful Brian.

Thanks.

The placement of the BOV is by the book supposed to be at the TB. When I designed mine, I used the stock Mass Air and wanted it to far from the BOV so it would cause as little problems as possible. I put mine there as well because it is supposed to release the surge of pressure that builds before the turbo. There are pros and cons to both.

Kewl, You are already ahead of the game. "FMIC"!!

So you had the BOV on the TB--->IC pipe at first and than you placed it on the other side is that what you were trying to say? I'm assuming you're not getting any surge/stalling with your current setup?

By the book it is supposed to be close to the throttle body. That did not work for me, the BOV was creating a massive turbulence and the air was venting backwards through the Mass Air.

The new setup is slick and ******* loud. I wish I had put it there first. It would have saved about $200 In Plumbing.

Read More about it in Maximum Boost by Corkey Bell. He Is A God.

I haven't had a check engine light or a stall since the change.

Later. I'm in Bosnia till April and it 10:30 PM Here.

Where are you getting your vacuum for the BOV from?

What you doing in Bosnia??

I am a soldier and we are here to keep the peace. My trade is Crewman (Tank Driver).

If you look on the picture of the engine, you might notice a set of blue vacuum hoses against the firewall. The first from the right is for the gauge the second is the BOV and the third goes to my EIC. It is harder for you because you do not have cruse control. Look for a place on your manifold to hook into. It has to be on the side closest to the engine after the throttle body to work.

Thanks and welcome to the Mazda Board.

I was going to tap into the brake booster vacuum hose because of it's size. But I didn't want to do that if I didn't have to just because. I noticed in those pics that's your's went somewhere else, that's why I asked. I have a decicated vacuum line running from the manifold straight to my wastegate actuator and a shared line that goes to my BPV and a boost gauge and whatever esle that might be on it. I need to get a dedicated line for my BOV now which is probably going to be the brake booster line. Thanks again for all you help.

Brian,

I went to try the IC on yesterday and the unit itself fits beautifully. However, I'm running into a problem running the passenger side pipes because the end tank ends up right where the radiator ends and right in the middle of where the AC lines run. Do you have any pics that you can share of where you ran you plumbing?

Thanks.

I will describe it to you, as I cannot give you a picture of it.
All the pipes run underneath the lower radiator mount. They are visible from the front (I like it ).
The Compressor flows into a 2" that does a 45 towards the car.
Mid radiator it turns 90 down to the road, 90 level towards the right front corner of the car, then sweep 90 up and 90 in the IC.
2.5" 90 Down 90 back...
You know what. This is not working.
There are a total of 10 Mandrel bends that make up my intake. It was set up after the IC was mounted, forcing me to not design it before. It took allot of testing. I used a rubber hose with metal inside so it would maintain a shape. Once it was done I counted bends and ordered them. Cut welded and Voilla.

Presto!!

I do not think it was any help was it...

Basically. Take off the bumper and attack it one bend at a time.

Aight kewl,

The bumper is off and mounting the cooler isn't a problem because it lines up with two holes that are already in the bumper support. So you have the pipes running under the car huh? No clearance issues?

Thanks again.

They are not that much lower than the car. I love the fact that they are visible from the front. They are Aluminium and hard to miss. People just have to look at the car and even if they know nothing about cars, they know something is not normal.
