Chargecooler - why would I buy I chargecooler from you over say ProAlloy? Suppose I want to run my supercharger setup on my Exige from 6PSI to 10PSI and need some cooling to help.
What would you recommend?
hi all …
Q to Frank and Chargecooler …
In all but standin on the line waiting for green light scenario
What outputs would you say its outside of the scope for a good A/A cooler to cope ?
Yes be interesting to see what they have for the front heat exchanger, this is in my books just as important as the main core, I again know what I have and why I chose it

The problem with the A/A is it’s location even a better core is still having to deal with poor air flow from the small intake slot…a side mount placement much like the VF supercharger kit puts it in the air flow of the side pods, they have made over 300 hp in that location…
Cool Frank …
I see that airflow is the Crux … Hence me sorting the roof (scoop and letterbox).
Ecu limiting the parameters : for me a thing of the past now … I’m not a racer , but , for road use in the UK @ 280 BHP i’m not suffering any annoying interference from the ECU
The car just "works " as and when needed…
Keep up your input “uncle Sam” … we love Ya !
It would have been nice to see a more efficent chargecooler core come to play…
Testing would be simple, same size heat exchanger, same cooling fan, same volume water and pump…Hot air in at a controlled volume/pressure/time and cool air out…
Hell if it were better than my bar/fin core I’d buy it…but as usual hype vs fact…
Here is a quote from the AVT website…:
On the flip side, the ambient air being used to cool the water on the chargecooler radiator has a much easier job. It has the job of cooling water by only say 20-30 degrees, and this is the same water cycling around the system. The other thing is chargecooler water temps are only marginally affected by outside ambient air temperatures, and even then, its also at a very slow rate. On an air to air system, if the ambient air temp rises, so does the charge temps, immediately. On a chargecooler system, this will also happen, but it takes a long time for that 5 degree ambient air increase to be able to raise the total water temperature 5 degrees.
This is the BS hype these guys are sellin…“but it takes a long time to reach ambient”… On what planet is the chargecooler water less than ambient for a long time ?
Ambient is just that ambient…it’s what it is period. When you start the car the air and water in and around the car are at ambient and yes the chargecooler water will get warmer than ambient, how much is dependent on the systems efficiency…
These guys are tryin to sell a product to guys that just don’t know better…
[quote=jfk]… Hence me sorting the roof (scoop and letterbox).
I’m not convinced dremmeling the letter box makes any tangible difference. The amount of air going to reach the A/A IC is going to be limited mainly by the size of the collection scoop(and speed). If you think the tiny bottleneck(which agreed it is) is going to be sorted by opening up by say 20%, then look behind it to the collection duct whose opening is the same size as the original letterbox. This cannot be opened.
Anyway, air won’t suffer the same as a liquid when it meets a bottleneck as it can compress (as well as speed up).
The side scoops offer an interesting alternative to add more moving air, as does improving the core. I’m still investigating better A/A solutions as I’m not looking for mega power and don’t want the complication/piping/weight of A/W.
The Lotus Sport GT3 car was given to the people that made the Red bull car to test to see how they was going to build there’s , the Lotus car was surprisingly pants in it’s design , at times it lost lots of HP because of heat and at times of heatsoak only made a real 240HP , ( I don’t know what part of the design was bad or what product before anyone gets upset and as far as I know the cooler could be the best in the world ! ) but the red bull car was built with more R&D than Lotus own and unlike the Lotus Sport car it worked well .
On the red bull car they went for A/A because of the big weight saving and it’s less restictive to boost and less prone to fail on track , stones hitting front rads and pumps letting go .
I’m sure franks bonkers HP car needs a C/C to keep it cool but with the GT3 340hp+ cars seems the A/A red bull is the best design .

Trust me on this … it does !!! Albeit with larger scoop too

Worked on mine without the larger scoop. Also not sure what you mean about the opening behind? Its much larger than the clam opening.
By opening up the letter box all you are doing is getting rid of the poor finish left by lotus and removing the flash they should of removed in the first place. ie opening it up to the size it should be.
I will add side air as I am still convinced the front scoop is not a great idea. If you have been in a 211 you will know how hot the air is coming off the front rad and until I see proof the other way I think air collected at the front of the roof will be warmer than half way down.

Can’t argue with a man that’s tried it, but it doesn’t make a huge deal of sense . (speaking out my +rse having done A level physics 20years ago!)
Boothy, as for the ‘opening behind’, it’s the collecting tube that snakes it’s way down the back of the rear window and over the front of the A/A. It’s what you see when you peer through the letterbox. To my eye, the opening of that appears the same as the pre-widened letterbox.
Whatever, I really think we’re talking small potatoes especially with regard to your comment re warm air, and yes I agree with the 2-11 warming your helmet!
661,
Are you coming to the Gunn Inn tonight ?

I know the part you are takking about, it is wider than the mail slot as i got mine flush with the dremmel and siliconed the edge to seal.
The yanks did airflow tests and it showed 20% more flow which must help.
When i went round oulton in an n/a 211 the heat off the rad was quite a shock, on a cold day it felt very warm all around my upper body, if the heat entering the a2a is warmer it cannot be as efficient as a cooler.

Oh man what happened to the chargecooler salesman, I thought we were gonna see something new and improved…dam I had my Visa card at the ready…
hahahahaha
Why aren’t any A/A rads built including peltier cooling?
I have always wondered why this isn’t seen, so I assume it’s been tried and is not viable for some reason? Both the in & out ends of the rad could easily be covered/made with this skin.
So boys and girls a clasic example of why we should not buy the BS products from guys using BS to sell their BS…ask for proof of their claims…
