Great information there.
First, I'd like to say that was much more difficult than I thought it would be. I had to remove almost all of the intake components to get the the #&$^#$^% wg actuator! My hands are sore and healing as I type

Anyway, here is my set-up. My only concern is the output hose is kind of close to both the radiator hose and exhaust manifold and that it may get damaged due to heat. I bought some 'aftermarket' hose that is pretty thick and rugged; it's 3/16" thick all around. I also put some electric tape around some of it for more protection.

Is this a problem, or is the hose okay for years and multiple Evo thrashings?

 

Here is the final product. I already tuned it to hold a steady 20lbs thoughout the rev range.

 

You'll probably be OK unless you sit in traffic a lot and don't have much air coming through the front for long periods. If you are really concerned with it, you might want to think about re-routing your lines (a pain, I know) or getting some wire loom/insulating material to keep it a bit shielded.

Hope you enjoy the constant boost to redline. I installed mine and had no boost taper as I climbed through the RPMs.

Edit: From the picture you just posted, looks like it wouldn't be that bad to re-route your line under the intake to avoid some temps. Just a thought...

 

I really don't want to re-route just because I would have to take a lot of that intake stuff back apart, though I probably should... I think I am just going to play it by ear. On the other hand, if the hose gets damaged I will have to start all over.

From the stock lines that ran to the solinoid I noticed there was a protective insulation around it, so I took that off and will put it around the new line and see what that does.



Just had a thought that I might be able to tape it to a coat hanger to the tubing and re-route it without having to take off anything.

 

Anyone else have an opinion?

 

Looks good. I routed mines from the actuator to the MBC under the my samco intake pipe, but other than that it is the same set-up

 

Ditto...

 

Looks like your factory d/v is backwards.

 

D/v?

 

Your diverter valve, or BOV as most people call it.

Also i'd recommend running the line under the intake rather than over it, that way it won't be near the manifold or anything at all.

 

Ah. What does he mean backwards? Like the orientation of it? I put the IC pipe hose back on the 'horn' of the thing while the base stayed in the intake pipe... and it's working okay...???

I have a feeling I am setting myself up to get slammed

 

But I think either today or tomorrow I am going to re-route it under my intake pipe just so I don't have to worry about it. I am really glad I left myself some slack in the hose!

 

Yep the DV is backwards. Turn it around.

 

Does it matter which direction it's pointed so long as it's hooked up to the appropriate pipes? :-/

 

The valve won't work properly until you have it oriented the other way. Some d/v's came from the factory installed wrong. Mine being one of them.
