Intercooler Fan Conversions

I've used charge cooling before and it does work - but is not as good as a good intercooler IMO

the problem with charge coolers is that the water in them gets hot and takes ages to cool down again

not a problem for a 7 sec dragster - but a problem for a car that sits in traffic geting hot

My guess is better air flow will fix the temp problems - somebody needs to build an intercooler scoop that sits in the airflow

has anybody placed an anemometer in front of the intercooler to check the air flow ?

This is a very narrow minded comment, and one I hear alot..

Most people do not know how to design a chargecooling system properly, and it is so much easier to get 'wrong' than an intercooler. Afterall, you just plumb an intercooler in and away you go - with a chargecooling system, every component and the design of the system is critical..

For instance, most people don't realise that the largest volume of water in the CC system is actually held in the pipework, not the pre rad or chargecooler unit. I then see people 'improvising' and using car heater matrixes as pre-rads, which if you measure them only hold around 300cl of fluid in the actual core..

Volume of water is very important. So the larger the pre-rad, the longer the piping and keeping the diameter as large as possible is also very important.

Simons GTA tested above is a far worse scenario of a rear engined turbo vehicle. The GTA has no engine bay cooling or venting. The rear glass hatch seals the whole engine bay, unlike on the Noble which has venting etc...

His results of around 15 degrees above ambient temps, is as good as any intercooler system mounted on the front of a front engined vehicle, let alone better than any hard to design and implement rear intercooled setup.

The problem is people are always looking back to the problems of other brands of chargecoolers from a few years back, which never used fan assistance (so you wont get heatsoak in traffic), poor sized pre-rads (so less volume) and weak output pumps, and the fact that their cores were designed in reverse (ie, the water flowed down where the traditional air used to flow, and the boost is blown through the middle of the core..!)

I used a 5 litre reservoir and mounted in the back of the car with piping that ran from front to rear

the radiator was enourmous - it filled the whole front of the car

i tried several pumps and several heat exchangers - the best results were a large intercooler that was welded to pass water instead of air - it was probably over 1 meter long !!

I also tried water injection with it

the best results were on the rolling road when it was filled with ice and water

in the end i stripped it all out and fitted a huge custom front mount intercooler - never had a heat problem since

Your missing one very important point....

Your engine wasnt in the sodding back though was it!

And you didnt try my chargecooler cores...

If you done all that, how did you have a problem with the water getting hot and not cooling down..

Probably by no fan assistance to the pre-rad, or your pump wasnt powerfull enough to circulate that quantity of water...or you didnt bleed the system properly..

So, has any one installed one of the CCs from DaveART into a Noble yet.

I'm still really pleased with mine, it has been supurb during that really hot spell in July. It does not suffer heat saturation at all. Even after a sprint or hillclimb of 2 minutes on full boost, it only feels as hot as a cold cup of tea, and the rest of the engine is ticking away like it is at melting point.

It does begin to absorb heat from the engine when switched off, but I can assure you that within 2 seconds of ignition on (this means without starting the engine), the warm water has been replaced with cool water. Awesome kit!

I'd be happy to come along to a Noble meet and you can see it for yourselves.
Much as I know David and have experienced his superlitive after sales support, I have no connection with his businesses.
