most efficient intercooler positioning?
right guys,
I need some advice here, I have an intercooler the fits really well in the nose cone of my car which gives me two options.
1, to gain maximum cooling have the intercooler sat so it is against the opening of the nose cone and open the nose cone up a little to allow more air
flow
2, leave the intercooler back against the framework and duck the air from the nose cone to it. Leaving the nose opening the same size.
would cooling benefit from having a deeper ducted area of positive pressure than having the IC flat against the nose cone bodywork?

The intake area is effectively the same. But the further the intercooler is from the engine the greater the turbo lag.
I would move it back to the chassis frame, but someone will be along soon to say the opposite.
p.s. I'm going with charge cooling for the same reasons!

I had a discussion with the techie at Kenlowe when fitting a supplementary auto transmission cooler to the tin-top.
His advice was to ensure that any cooling components such as water rads, oil and trans. coolers (and presumably intercoolers) should be fitted as
close to each other as possible i.e immediately behind each other (IIRC a 5mm gap between each) to avoid the airflow being disturbed.

I know they need to be close together but if the IC is at the front will the air go around the front of the car rather than through the IC.

I would suggest mounting the IC as far back as possible and infront of the other rads, leave alittle bit of a gap inbetween.
Shroud the sides of nose opening back to the edges of the IC to create a tunnel. This will allow air through the grill opening at the front but not
escape around the sides of the IC greatly reducing the flow.
Try and get as much free space behind the rads to allow free flowing air to travel through the rads and escape.
IC should be at the front.
This info is based on my knowledge or air flow and poking my nose in and around many race cars in the past. I am no motorsport engineer!

When you say free space behind the rad, do you mean un-obstructed?
It will deffo be ducted from the nose cone and then i will use some thick self adhesive foam to seal the gap between the IC and the rad.
