Rubbish written in motoring press

[Ian Podmore]

This just doesn't make any sense to me Auto Express:

 

Huge 350mm brake discs at the front provide some serious stopping power but need to be kept cool, and the tweaks to the engine mean a wide intercooler is needed at the front. In fact, when Ford was designing the Focus RS it chose an intercooler that was so big, part of it has to be covered in the production car to keep it from doing too much cooling.

 

How can an intercooler ever produce 'too much cooling'.......  To big due to too much lag, yes, but not too big as it cools too much.

I suspect there aren't many motoring journalists who really know what they're talking about...... Even on some of the Youtube channels (like "Car Throttle"), they come out with some right nonsense.

 

In much the same way that Rory Cellan-Jones is the BBCs technology "expert", but the guy hasn't a clue, he just regurgitates sales/marketing nonsense and bangs on about Apple products all the time.

Ford found that the intercooler was so efficient, that under certain conditions - ie when it was very humid, it was causing a build up of water vapour. So it was fitted with a small blanking plate from a transit.

That's the official Ford explanation, anyway.

Condensation inside the intercooler? They should just turn the boost up to make it warmer...

[Kit Car Electronics and Essex AO]

That is correct, Dave. Cooling hot humid air through the dew point can cause enough water condensate to create a misfire. A very small drain hole on the intercooler is one possible solution but obviously isn't great for holding high boost pressures!
