Been thinking about the Intercooler....

[Draco-REX]

So I'm very curious how the intercooler is going to get air. Because we haven't seen the full body model, I'm not sure what FFR is cooking up. But I've had some ideas.

It's probably too late in the production cycle to do this, but I was thinking of a Spartan crest styled intake like you see on the Lotus Exige and Zonda-R to capture fast moving air from above the front seats. It could be directed down into the stock location intercooler. However, with further thought, I had another idea. With a couple brackets and longer hoses, you could stand the top-mount up. That way, you could direct the flow from the aforementioned intake through the intercooler but then out the back of the fairing to exit over the rear deck. Picture the intake from the Zonda-R, but wider at the base and with a rear exit like the back of a roof scoop on a WRC car. The effect would be like the intercooler on an RS200 but with shorter piping runs, making a happy compromise between a Front-Mount and a Top-Mount.

It's a wild idea, but it'd really make the 818 stand out, and it doesn't seem too difficult to do. I might even attempt this...

Do you mean a roof mounted intake?

Would it then be a "T-Top" if applied as a targa or open top model?

Yes, we beat it to death already, but I think he wants to present a new idea.

I'll be using a water to air intercooler. Two 12" radiators with 7 inch electric fans. They'll be mounted around the side inlets instead of up front, to keep what little they weigh in the center and low in the car. And to reduce the amount of tubing needed.

I thought that the intakes on the side of the Lamborghini Miura would make good intercooler intakes, so I attempted such on my design.4516

[crobin4]

Generally, any type of opening opening to the outside of the car is good with the water to air, if using fans. It's much more efficient than air to air, so a huge volume of air is unnecessary. The down side to such systems is: during VERY long duration under boost, they can heat soak. Those conditions only normally exist on a road coarse.
Water/Coolant has a very high Thermal Mass, air has very little.

I'm interested in the air-to-air setup because of the lower weight compared to an air-to-water system. 1 gallon of water is 8lbs and then you add the weight of the pump, seconday radiator, and heavier water-jacketed intercooler.

For a mid-engined car, I do think an A2W system is a better solution for the format. But in a car where light weight is part of its arsenal (like an elise) I don't want to give up 10lbs that don't *have* to be there.

I will need to have a 1800 lb. minimum weight. I may need those 10lbs., they may as well be of use.:)

I think both approaches are completely viable. It's my feeling that on the "average" build, (mostly stock with OTS Map and Exhaust/Intake) that air to air will be all that's necessary and desirable in a Spec racer.
I think others that plan on pushing the envelope on power will find the water to air is an elegant solution for effectiveness vs packaging constraints.
I'll continue to play devil's advocate for water to air, I think given the package, it solves quite a number of problems.:cool:

It wouldn't have to go all the way to the windshield, it'd get plenty of airflow above the headrests.

i sometimes think about intercoolers too... i find that keeping busy takes my mind off them

anyway i plan on using a top mount JDM sti one which should be fine... an AMR maybe... but id rather spend the money later

since the fuel tank is no longer under the seat, perhaps a complex under car scoop and air routing system to mount a front mount intercooler in the middle... a MMIC if you will

Heh... this just gave me the insane idea of an 818 Chapparal, with a skirted floor pan with an opening for the intercooler and a sealed engine bay with twin fans in the back sucking air out. lol
