View Full Version : FFR Supplied Intercooler Duct pieces

The LH side piece has 1.5" clearance and the RH side a whopping 3.5" to the engine cover. Expecting those pieces to guide air to the IC is a stretch.

The attached photographs show mods to make the setup "better" [no bulb seal is on the pieces yet]

I'm also raising the height of the piece directly behind the openings in the engine cover, to be sure the air that does come in makes the turn towards the IC.

Reading the posts about IC's and inlet air temperatures, it is a mystery to me why such apparently ineffective ducting is supplied by FFR (for us guys who are keeping the stock IC for the moment!!)

Hey freds,

Some flat rubber (flapper) gaskets made from inner tube could fill those gaps and smooth it perhaps enough to eliminate some of the air escaping an reducing turbulence due to the sharp edges. Along with the bulb seal, that might give you better gradient for the flow into the IC. Just a thought. WEK.

Or you could get my air to water intercooler and solve all the problem :cool:

Absolutely no doubt Wayne. :)

At this stage it is a simple budget issue, and I'm not going racing, and have a mild tune.

I am, thanks to you, and others, discussing this subject so fully on the forum and am mindful of this very important issue.

Thanks

That's why I'm relocating an air to air IC

Do you have any worries about creating Turbo lag?
I see all these pictures with front mounted intercoolers and I wonder how real is the turbo lag problem really is.
Your SMIC piping is less than FMIC so should be better.
What did you do with your blow off valve?

You will get a bit, I used 2 1/2 inch pipe, 2 inch will fit better. I have less than 7 feet of pipe.

How many CFM can we expect to be flowing and what is the volume of air in that much piping? It will be offset by much better IC cooling, my IC is 40% larger and is a bar and plate design with no obstructions behind it like the stock one has... Like everything else that we do it is about trade offs. With a significant scoop capturing air and a 10 in fan behind it, with the large open vent in the rear I think air flow on the side should be very good.

I cut off a piece of 3/8 thick aluminum plate to match the BPV. I welded a 1 1/4 AL tube to it and welded that same size tube into the inlets 2 3/4 aluminum tube. They are connected with a silicone coupler. So the BPV works as stock.

It must be noted that I have simple, reliable power goals. I have a Cobb Accessport V3 and plan on running their stage 2 tune for 91 octane (not much 93 avail in Maine) using a basic cone filter intake and a tubular header and 3 inch exhaust with Cat and SS muffler I should see 240 or so at the wheels. More than enough for an 818S with an expected GVW of 2400 lbs

Bottom line, the FFR setup can not work. AWIC is a great solution but I wanted the simpler AAIC setup and there is so much empty space in the side pods. Even if someone goes AWIC the sidepod is a great place for the heat exchanger.

I also love the idea of a CF scoop on the side... my next dilemma do I run a symmetrical setup or not?

Hi Dan,
I'm in total agreement with you. Even down to the carbon scoops.
I will put scoops on both sides, I need a lot of air for my rear mounted radiator.

sure, hog out the sides, make up some ducting and you should get good flow through the rear of the car. I assume that you will do the same with the two little IC vents can you get improved flow through the radiator somehow through the trunk vent? I think that is a low pressure area without some sort of fast back top. Even the FFR convertible top leaves that as a low pressure area.I'm not planning on using mine...

We need to keep nagging Craig on those CF scoops! :)
