IC Additional cooling

The Oily Bits S2 Specific Topics

Having looked at the RLS option of getting side air into the intercooler I set about designing my own.

Key points for me were:
1)Leave L/H scoop alone so as not to interfere with intake…
2)Increase ducting diameter over RLS to compensate for using one side…(RLS use 2.5 inch)
3)Not obstruct anything so as not to make access to service parts awkward…Ohlins resevoir etc…
4)Reasonable cost…

Here’s a few pics…

3 inch air entry




Scoop in side pod

Again




3 inch ducting

Total cost �57 !

Really neat job, and nice price :slight_smile:

Are you now taking all the air from that scoop to the IC. Any concerns on keeping the alternator cool?

Cheers Will …
Not all the air no … In the 3rd pic you can see the gap for the excess air to pass…

4

What about the mesh in the side intakes? maybe leave it out to help with airflow?

5

De-meshing would Deffo increase airflow … just depends on the size of creature ya wanna catch !!
:wink:

6

my new ones that are coming are going to be de-meshed as well, hope to have all my stuff organised by angelsey :wink:

7

Get a day job Jeez lol :smiley:

8

Looks like a good job , just one thing though - where’s the carbon ? :slight_smile:

9

The UK is out of Carbon, I bought the lot :blush:

10

Added a second 3 inch duct today too …

Slightly smaller duct on the left side so as to allow air past for intake.
Easy enough to do …About �130 for the bits to do both sides…

11

How do you attach the side scoops?

Where have you found the scoops and alu air entries?
… or do you sell this kit?

Good job!

12

Scoops just bonded in place with RTV sealant …
Aluminum couplings bonded in using epoxy then RTV to strengthen…spread stresses.
All the bits aluminum and duct etc are from Demon Tweeks in the UK …
They do mail order … :wink:

Good job John, looks good. Have you noticed any difference in driving, i.e. have you let the car get really hot an then noticed it cooling quicker with less soak?

14

To be honest Mark , ever since I ditched the standard IC I’ve never noticed any heatsoak…I don’t commute and sit in traffic… and when I go for a drive its on open roads .
I’m just building in ‘headroom’ for the next steps … and I really enjoy improving the car while I’m short on work …
Looking at the aperture that the roof scoop squeezes air through , I would say that now it probably flows around 300% of standard …DISCLAIMER…I,m estimating !

I’m taxing it in the next few days and will be at Anglesea.
Hope you can make it .

15

Total overkill for 6 psi by the way …

Frank ,come back dude , I miss ya :frowning:
I’m bored past 00:00 UK time … Wake up !!!

16

Glad it will be back on the road soon John, think I will be coming down to Anglesea for a few hours to watch tho :frowning:
unless some more spare places appear.

Jfk… curious about the roof scoop mod. would the air not be forced in slower? just thinking about a hose pipe, smaller aperture forces the water out faster/further. i’m no expert on IC’s so have no idea if they like controlled air literally shoved in, or prefer air in abundance??? I’m still learning so your view appreciated.thanks

18

it’s VOLUME of air passing through the IC fins that cools the intake air … Bigger roof scoop + additional ducts all increase the volume passing over the fins…

gotcha…do you have a forge? silverstone Lotus said that Lotus do an upgraded performance IC?

Here you go … :wink:
