BOV location for my new IC setup

[belize1334]

Some of you may remember the 6x6 PWR air/water IC setup that I was running. I found that it wasn't quite as awesome as I had once hoped and as such it is being replaced by the monstrosity you see here.




To finish the install I have to adapt my turbo outlet elbow and I also have to mount the BOV (and find a nice curvy upper radiator hose). From the research I've done there seems to be a bit of debate about whether it is preferable to mount the BOV before or after the IC core and there seem to be arguments both ways. As a simple fitment issue it either comes down to hard-mounting it on the end-tank AFTER the core or incorporating it into the j-pipe. That being said -- and with my flame suit securely in place -- I await your comments and suggestions.

P.S. I know that there is also debate about the suitability of air/water intercooling on a daily driver. Let's please leave that discussion for another thread and restrict this conversation to the fitment issue at hand and theoretical debates about BOV location and functionality. /ubbthreads/images/graemlins/wink.gif

I would put it on the endtank next to the strut tower, with the flange facing the firewall.

I think if I do it on that end-tank it'll actually be on the underside with the flange facing down. The tank is flatter on that section which would make it easier to weld a flange. Also, since I'm recirculating it seems like finding a hose that will have 2 90 bends in just the right places is less likely that finding a hose w/ one bend and a long straight section.

Oh, yeah, that sounds fine as well. Sounds like you know what needs to be done, so have at it. /ubbthreads/images/graemlins/smile.gif

I agree with Wop's analogy to a balloon. It doesn't matter where you pop the balloon with a needle, the air rushes out the same. Put the BOV wherever it's easiest to mount.

Good luck and it looks like an interesting setup. Nothing wrong with being different.

 

^That was my analogy!

i tried finding the thread but it was from years ago... /ubbthreads/images/graemlins/crazy.gif

Actually, for shits. I did find it and it was a year ago. Didn't take that long.

I just need a public apology. That's all. /ubbthreads/images/graemlins/rofl.gif

 

[CarRacer]

My mistake.

I guess I mistook a crackhead look alike with a beard for a former dirty hippie with dreds. /ubbthreads/images/graemlins/rofl.gif /ubbthreads/images/graemlins/rofl.gif :rofl

 

^Worst apology ever!

Anywho, I like the new IC but I would a big j pipe made if you aren't already.

I look like a crackhead? /ubbthreads/images/graemlins/rofl.gif

I'm not sure how I missed that BOV thread. I usually keep up w/ all the tech discussions on the boar but I apparently let that one slip by /ubbthreads/images/graemlins/dunno.gif. Anyway, I think I'm just gonna get the j-pipe that I have rewelded so that it points straight up. It's a RRE mandrel 1.875" which is already bigger than the turbo outlet so I don't think it'll be a flow restriction. Getting it pointed straight up I can connect it to a 6" piece of 2" mandrel aluminum that I have and then couple straight into the IC. I know alot of people run bigger than 2" but I really can't see 6" worth being a restrition w/ a gentle bend basically right on the turbo outlet.

Sorry for crapping on your thread.


I just remember that pic of Mark with the seashell crack pipe. I know Jay doesn't look or act like a hippie either.

 

[belize1334]

^^ Haha. You're not sorry. Admit it!

 

[Hertz]

After the core will give you twice-chilled air. /ubbthreads/images/graemlins/cool.gif

 

[belize1334]

Well it's done. Got the j-pipe welded and I got a flange put on for the bov. I have to give a Huge thanks to 324vr4 (Ryan and Richie) for contributing their time to help a poor grad student like me get this going.



Anyway, I did the Dejon BOV mod and now the BOV is fluttering (compressor surge?) when I let off at low boost. Does anyone know where I can get a 3-way pressure actuated pilot valve like the one they sell in their kit? I'd rather not pay them $50 for just the valve if I can find it on my own for cheaper.

 

Nice setup! I like the recirc underneath. Very clean.

sweet setup - real ninja...

who fabbed up your tierbo outlet??

 

[324vr4]

Lookin' sharp Roger...I'm curious to see how much "better" this setup will be compared to your previous setup...Where did you decide to mount the IC? Tranny, subframe? Face?
