Any pics of his project?

I'll see if I can get him to post some on the forum. From what I gathered it may only suit RHD cars.
Could be even more effective if a hole in the cabin air intake was cut to give a replenishing cool air supply into the cavity. It is in a state of positive pressure at speed due to the airflow against the windscreen.

If you had long enough lines, you could even put it in the trunk, where it would stay really cool! It would be a lot more work to route it, but it would probably work out well, if you routed it like the battery.

You're not wrong however, I wonder if making the lines excessively long would influence shift times.

I've seen some track cars with it on the transmission tunnel. That would be most ideal I'd imagine.

Yea I honestly wonder this myself, or if they change much in the bin location.

on the transmission tunnel, interesting. I'd love to see a picture of this. Seems like it would be harder to work on.

The 'bin' would act as a shield between the heat radiating off the engine block. With no local heat supply it makes sense for it to be quite a lot cooler. With an exterior air supply it should do even better again.

I saw it some time ago during a random google search spree. From memory it was it was passenger side footwell on a RHD track car. If I ever see it again I'll share it.

I did just find this though which is similair. http://www.m3forum.net/m3forum/showt...p?p=1067222409

Didn't have to extend any electronics, just got HEL braided lines to extend it.

It's the cold side of the engine so it should experience even less heat than OP's.

When my SMG pump warranty runs out I intend to have a go at it myself.

I think on the 03+ models there's a little more space in that area. I know on my 02, there is no way you could get an SMG pump in either side.

I saw a photo of a guy with a track car who had relocated it to the where the passenger seat used to be. I'm thinking down the line i might relocate it somewhere behind the front seats in conjunction with a rear seat delete. Route the hydraulic lines straight through the trans tunnel or something? So far i've never had a serious issue with it so *touch wood* that's a project for another day far away.

edit. i see you found that same photo above lol

Once i get my kit sorted out with vince i am planning to do the gold heat reflective foil in and outside the bin. Just a little extra work but better for the heat.

Here are two pics from that BMWMazing fellow, he used a IR cam to catch the temps on the engine and in the bin at the same time, seems like a pretty significant difference! I think it would be easy enough to route a fresh air supply line to the bin too...

How much airflow does the existing position get when in motion? I just got home and opened the hood and stuck my hand down there and it didn't seem too bad at all.

I was traveling at highway/burbs speed with temps hovering the freezing mark though.

Not sure about airflow there but many guys store a spare quart of oil there. I wish I could find where it was, but I remember seeing someone cut a hole into the bin, with ducting running from the front bumper and feeding into the bin, along with the air venting out the fender grill once it passed over the smg pump. Seemed like a cool idea. I am sure wrapping the pump and lining the outer walls in gold foil would help deflect some of that radiant heat as well.

Is this what your referring to?
It'll go out the side gill, just not done in the post.

I definitely missed that thread! Thanks for sharing!! This is much more comprehensive than the one I saw. Looking forward to this all coming together! It is possible I confused your plan of adding airflow ventilation with Marco Bleiker's relocation (BMWMazing in the youtube video), seeing as I am having difficulty relocating the source.

Here are some other additional links from Marco Bleiker's relocation that he directed me to when I asked him about it in the past:
