What are you using to physically mount the fans onto the intercooler. Hard to to see from those pics.

Zip ties with washers. The zip ties fit nicely between the fins, and gravity does most of the work. I used rubber coated washers on the bottom. You can also look at the Spal website in the accessories area for mounting options.

Well this one on the way...2.5" deep, same dimensions as the core and 1600 cfm. Wired up the relay and engine compartment fuse panel today.

That is a great design for total coverage.

Nice. Tremendous improvement over non-fan setups, you will be quite pleased.........

What a cool idea and find!

You'll have them on top, blowing down, right?

Let us know how it works -

Very cool idea! You'd need a higher than stock tail to accommodate it though? Perhaps something like a RS 3.8 Turbo Tail, or a GT2 Tail?

Hmmm... I might consider doing this for my TT IC too

Check my first post in the thread, that's the tail its going under. Its a Lemans tail from AIR. It allows for 7.5" of clearance over the fan buckle. With a 3.5" Bell intercooler core that gives 4" under for hanging the fans.

Now THAT is a SERIOUS tail

I also like the DP Extended 964 tails

Yeah, it looks especially oversized on a narrowbody car. I am sure I'm going to need more rubber so GT2-style or full flares will eventually need to go on, once funds free up again. Just want to get her back out on the track now, even if I am lacking traction...

Also be interesting to see how balanced the car feels front-to-back under speed. The nose used to get light down the straight until we slammed it to the ground. I may need to add a splitter to the RSR spoiler on the front...

From what I understand 930's can get heat soaked at idle in traffic. Heat rising off the motor can counter act the low air exchange rate at idle. I suspect a proper fan system might help there.

However, air flow over the end tanks and around supply tubes can contribute toward IC maximum efficiency. Thus, on the track there is a lot of air movement in the motor compartment so shrouding is not as important. On the street it becomes more important.

On my C2 Turbo the IC shrouding was removed after welding in a thicker core. However, on a C2T the AC condenser and oil cooler is moved to the front of the car so there is also less thermal load during the summer to contribute to a chimney effect.

Gabe's tail has mine beat for square footage and Jack's beats mine for cleverness. Also the rear-exit one on a few days ago, sorry to the owner I don't recall who it was but I admired the installation. I also played around with mimicing it.

Just to clarify Glenn, the fans/shroud will be hung underneath the intercooler so that there is no obstruction to ambient air flowing over/down through the cooler as well as getting the weight down low as possible. The fans are set up through a relay to switch on whenever the coils are on. I toyed with a temp switch and my ECU can switch the relay on/off depending on intake temps but for simplicity's sake I made it as simple as possible to start with.

Also tested and confirmed the diff temp gauge works properly (dropped it in a cup of hot tea!)

Gerhard thought 3" inlets and outlets were overkill for 500hp but agreed less restriction is better. We spoke at length regarding core depth. For a track car he thought more than 3.5" was overkill and dead weight since little idling was involved and given the fan plans. We settled on the plans on the previous page. Heat sink in a street car would more likely be an issue without the fans. Oh, and QDC (Hargett) quick disconnects.
