Will this Intercooler work/fit into a 928?

It's in!!!!
It went in with only slight modifications. I will say that this is the largest IC that one can fit into a 928 withouth any cutting. the driver side tank clears the headlight armature by about half an inch! Tomorrow I have to get 2- 90 degree rubber elbows to connect the two ends of the piping, shorten the lower rad hose by 1" and that's it. The drop down brackets for the radiator were easy to make and the intercooler top/bottom mounting brackets were a breez to make too. So far, except from buying the IC, I haven't spent any extra money on this project. Spent about 5 hours working on it and at least 2 more just planning the layout. It's getting really tight in the engine compartment. With the oil seperator/catch can on the driver side and the rest of the piping on the other side, any future addition will have to have a small foot print in order to fit. The overall lengs of the piping is 1 ft. + the width of the IC more than what it was before. The electric fan had to be installed infront of the IC. After thinking about this, it occured to me that this might actually be a good setup. Every time the fan turns on the IC will also get cooled. With a remote switch I can have the fan on to cool the engine and cool the IC at the same time. This will be great to cool everything down between each 1/4 mile run.

from the looks of these photos...you have your BOV on the intake side of the intercooler... why ?? I'm a turbo guy myself, and thus am not familiar with supercharger type installations...but all the turboed cars I've built and worked on, had the BOV between the intercooler outlet, and the throttle body. Also... what is the lower hose thats unconnected in your pic for ? does it go to some air filter or intake of some sort ? Not dissing you..I'm just trying to learn something about the supercharger type of boosting, vs. turbocharging which I have had turbo cars for more than 20 years now, and am very familiar in their plumbing, as of 1985 with my Starion ESIR through 1995 with my 3000GT VR4, and its subsequent upgrades...

The BOV the you see is actually a bypass valve. The elbow that is attached to was originally on the driver side and I just simply relocated it. I did some research on where a BOV/Bypass valve should be installed. I figured that if it's before the intercooler the intercooler will mostly be kept unpessurized and heat soaking will be less of an issue. You see, bypass valves vent all the time except when there is boost. Putting it before the intercooler makes more sence. In my setup, the MAF sensor remained in the stock location, so from the air metering point of view it doesn't matter where the bypass valve is installed.
Then again, I could be wrong and maybe the bypass valve has to be after the intercooler.

Nice work Imo!
Btw, you are right, BOV or bypass valve before the intercooler. No reason to cool what you don't use, makes it much easier on the IC.

Also...with turbo systems anyway...compressor surge is most effectively reduced, with an appropriately sized BOV, located as close to the closing throttle plate as plausible to locate it. This allows the quickest release of the "trapped" pressurized air in the piping, and allows the turbo to respool more quickly upon resumption of the throttle opening. Hence my comment about the BOV being on the "wrong side of the intercooler"...

Jeff, the TB is after the IC anyway, so having the BOV before or after the IC will still serve the same purpose. The air is still pressurized before the IC, this way you are not releasing cooled air or building up pressure in the IC when its not needed.

Thanks for the comments guys. How I have to wait till the weather is good enough to go for a test drive. I have an infrared temp gun and if I can rig it up, I will take some reading to see how effective the IC is. I know this is not the most effective IC out there but since I didn't have one before it should be better than nothing.
Jeff Jackson,
I think the mean reason turbo cars have the BOV after the IC is convinience. It's alot easier to install it after the IC because that pipe is usually located on top of the engine. Also as you mentioned, it react quicker when the throttle closes and turbos are more effected by surge than superchargers. SCs are connected to the engine by a belt so they don't really slow down even if they are surging.
The combination of this and to keep the IC cool, the BOV is better if installed before the intercooler.
