Intercooler test - Results

Welcome to the forum Jon, where are you based?

Wellingborough Northants, not far from J15/J16 on the M1 or J10 on the A14.

Boothy ( Am I selling or not ) get’s in quick to be experimented on !!!

Head and Shoulders need to test a new shampoo next week - fancy having it poured in your eyes first :smiley:

Good to have you on this thread Jon , it would be interesting to hear your opinions about this test and the different intercooler cores ??

Hi,
As we said earlier we were keeping a close eye on this test and the results were suprising. The Marston core technically should have outperformed the rest, most of the Formula 1 teams use Marston cores for there radiators. It seems one of the key areas for performance is airflow to the cooler and then disbursing the heat out the rear efficiently.
We manufacture radiators, oil coolers and intercoolers for some of the current British and World Touring car teams and work very closely with our core supplier and are confident we could compete with whats already on the market. As we said previously there is currently some new core technology being tested so it will be interesting to see how that performs. We are also currently making a triple and a single pass radiator to see how much interest we get. It will be very similar to what is already on the market, the core being the only main difference. Depending on the result we may make a batch of them.
Just to let you guys know we have just done a website update that now includes a news story and a few pictures of the engine oil cooler we made for Fluffy so feel free to take a look at www.jcweldfab.co.uk

What kind of pressure drop on your tripple pass radiator with the Toyota water pump and engine at 3,000 rpm vs a single pass ?

Frank if there is a problem with the Toyota water pump on a triple pass do you think there would be a problem with a K-series water pump on a triple pass rad? :confused:

I’m not sayin there is, I’m wondering if they are doing real R$D to sell their product or is it just the same old “this guy is using it so it must be better”…

So if it is better lets see real data… but that’s just me, I don’t believe anyone…

Should I put my standard rad back on? :crazy: I’m really pleased with what they have made for me. If it doesn’t work then I’ll put it in a cabinet in my living room because it’s a fine piece of art. Clicky

I keep readIng all these references to F1.

Is it research or just making a product to a predetermined specification?

Sorry for the late entry to this discussion as we have been waiting for a password.
I am Liam from MMG PERFORMANCE and if there are any questions please feel free to ask.
Moomin mentioned JSRACING were doing some testing so we were more than happy with throwing some product there way for testing.
Just so everyone is in the know our stage 1 core is one of the best cores we could source within the first price bracket of tune.
We tested this core in one of our vx220 turbos and saw a 20 degree drop throughout the test. However we had a boost pressure drop of 4 psi and as a result it never went any further and we ended up using a less restrictive core which saw temps drop around 15 degrees with no pressure drop.
As this was a turbo set-up the car was never providing the cooler a continuous pressure, hence the reason we decided to try it on the Exige s.
The cooler is one of our prototypes and not available for retail, we were as keen as you guys to see the results.

Right onto the results.
As all the manufactures im sure will agree, with any increase in volume or density there has to be an increase in pressure or else they simply won’t work.
So from the test a stock cooler is fine on a stock car but once moddified how long before it reaches saturation?

Why the uprated coolers didn’t seem to work-
There are many ways of trying to explain it in a simpler way, some of which are on here.
Imagine a single air bed as the cooler and the air inside as the boost pressure, now increase the size of the bed to a double but only us the same amount of air from the single. The double can now not be used because there is not enough air to fill it, the coolers work the same way.

The marstons core dosn’t have to be visually larger as the core is so dense.

I hope not to bore you with any of this, but an uprated intercooler is exactly that and as a result all the uprated cores need to be tested on uprated cars.

Sorry if this reply went on abit just trying to answer as many questions as I can in a single post.

Please feel free to ask any questions

Hi and welcome to the forum .
Just a quick observation Liam …
I’m running lots more boost than most people on here using a forge cooler ,I also run extra air Via side scoops to the forge and simply cannot get my temps anywhere near as high as others report …
Admittedly this is not on track but some very long uphill sections of road …

I have read somewhere that they test parts that go on F1 cars so if a product is used in F1 you would like to think that it does the job if used in the correct way. I chose a Zircotec coating on my exhaust because their products have been proved in F1.

Let Sean drive it on track!!! Very long uphill does even come close, unless its 40-130, repeated all the way up for 10 minutes?? :slight_smile: Once its fixed that is :cry: Forge was tested on standard car, with extra air added pretty much as yours is.

Appreciate that it was a STANDARD car. Bur some of the coolers are sold as a fix to the heatsoak on a STANDARD car.

Any cooler used in F1, GT, WTC, BTCC, etc does perform. The main difference is that the cooler/core is spec’d by the team, manufacturer, engineer to do a certain job, within a certain size/weight constrainght. Hence the use of a Marston core, which is a pretty cool, no matter which way you look at it. But does sit in the cleanest, coolest, highest flow of air on the whole car.

Question is, does anyone know the speed/volume of cooling air across the intercooler core?

I hate to say this, but if they don’t, then any solution is a best guess.

constrainght

constrainhtg

contraint, even. Can we have a spell checker on the forum, please Mr Admin???

Sorry but I don’t get it, the job of the intercooler is to cool air. Hot air enters at one side and travels across the core being cooled by heat transfer into the core. The higher the performance of the engine the hotter the air is that enters the core and it’s also traveling faster through the core having less time to transfer the heat.
I just cannot see how if a core is not working with a lower output engine feeding more heat into it can possibly make it work better.
Seems to me that with the low cooling airflow in the exige the denser cores just cant work as there is not enough air to keep them cool and they are heat soaking.

I see where Boothy is coming from …( by the way folks Boothy is a heating engineer by trade )
I suppose the intercooler is very similar but is working in reverse to the heat exchanger on a combi boiler …and to get hotter water in our bath a combi boiler turns up the flame ( like more airflow through our intercooler)
Then it also slows down the flow of water so more heat is exchanged ( more restrictive core) …
I think Frank had a VERY valid point when he stated any testing should be done on a dyno with CONTROLLED conditions …

The physics seem very simple to me and probably to you,having done HVAC exams…
One things for sure tho … there will always be conflict on ere …
:wink:

Bang on ! ALL aerodynamics are a guesstimate …Even the most powerful computer programs don’t come close to predicting airs behaviour ,if they did wind tunnels wouldn’t be needed .
Quite simply the cooler and more volume of air passing over the core the better …
BIG air tubes
BIG air collectors
EASY exit for hot air

It works !!!
Maybe a chargecooler is better but its a lot more dosh than a couple of scoops and a hose pipe ???

Sorry, but sooooo dont agree with that. Thats some wind tunnel if you can get a 747 in it, and I don’t want to fly in anything that has its lift/drag coefficient guessed at!!! CFD is where its at to prove the concept up to a high degree. But its all down to how much info you have - garbage in, garbage out.

An Exige is not an F1 car, Indy car, plane, etc. Am pretty sure its seen the basic test only inside a wind tunnel to make sure it doesn’t do a TT, if that.

They are pretty cool at what they do tho, in any form.
