Whats up everyone, I know a few people do fan mods on the back of their ICs, and I was browsing and came across this ( http://www.electricchargers.com/?gcl...FSE9gQodzF3x-Q ) and was wondering... could you place this on the back of a SMIC, ducted so that no air is released except through the fan after the IC, and maybe even have a pipe that leads to the intake? How hot is the air after it flows through the IC fins? I know it's probably a stupid idea, but I'm just pondering a few ideas and wondering what other's views on them are. Thanks!

 

IMO, it looks like a lot of effort for little to no gain.

 

Well my thoughts were that since the SMIC is such a heat sink, maybe if there was a constant flow of air, even when stopped at a light, it might lower intake temps by a few degrees? Just an idea...

 

Then your best bet is to get a vented hood, like the Mazdaspeed, which has a vent right over the SMIC area. Then, get a standard fan for the back of the IC. Next, make ducting from the fan shroud directly out of the hood vent. That would be about as efficient as you could get.

 

Sometimes people do put fans on aftermarket SMICs but I'd imagine you would want a fan closer to the style of the radiator fans. As far as feeding that air into the turbo you'd probably be better off trying to duct fresh air over the heat soak IC air.

 

That does sound like it would be best, but I'm thinking about all of this with the factory hood. By the looks of it, doesn't appear to be as good of an idea on here as it was in my head.

 

By then you will have invested about as much as an aftermarket SMIC. So I do think the question bears a lot of value, especially for cars run at stock power that don't need lots of mods.

Running the post-intercooler air to the air intake is a fundamentally pointless idea. Because now the heat coming off the intercooler goes right back into it again.

As for using this device in particular, I think a ducted fan like you see on the radiator is by far the most practical / economical design.

That would have to be done on an afermarket IC. The stock IC isn't big enough for a fan on the back (at least one that would pull any real cfm ).

 

well the fan in the link I posted appeared to be flexible to some sort of modification... but I definitely don't think a flat fan like the radiator uses will fit...

 

I think the Fridge Perry would agree:

Although I can say there is a huge difference in intercooling with the stock intercooler when the car is sitting still, such as on a dyno. I can see even a small fan would make a huge difference in intercooling as long as it keeps air moving.
