nice new big intercooler

[Arightpest]

Hello All

I know if you spend lots of money on a nice new big intercooler from the likes of allard? Etc it will increase torque but what if you put two standard intercoolers together doubling the cooling area will this do the same job? I know the piping might be a bit messy but will it work? The only problem I can think off might be the increase in turbo lag due to the increased air track. Does anybody else have info on this.

All the best

You hit the nail bang on the head - pressure drop. You can take a standard intercooler and smooth the edges of and it'll improve performance ('gas-flowing' it's termed), so imagine the issues when threading two togther. This why intercoolers get bigger or thicker, and not more numerous.

fitting an intercooler (or two) on its own wont necessarily do a lot for performance unless u increase the fueling as well to make make the most of all of that lovely extra air.

And thats a fair point, too!

well,ya see,on an audi S3 it is fitted with 2 intercoolers & has roughly 8 feet o pipework before the air actually reaches the throttle body,there will be a drop inpressure but i wouldnt hve thought it would have been much,if so fit a bigger turbo  :lol:

But those intercoolers are designed to work like that... Land Rover ones aren't.

The plain Jane A3 fitted with the 1.8 turbocharged engine is fitted with just one intercooler.

When they wanted to upgrade the performance and due to the fact of very limited space they decided to fit a twin intercooler system and it does work very well.

Fitting a larger intercooler is of course a much better option but when space is limited a twin setup (or two stage as Allard and the others call it) is a very good option.

The pipework is extended in length but upping the wastegate operational pressure takes care of the problem. Differences are so marginal that I do not think it is worth doing it.

I have fitted a full frontal intercooler bought from Alan Allard back in 1996 in my ex CT Discovery 200Tdi and it does make a difference.

Having bought a two stage intercooler to add to my second camel (again a Discovery 200Tdi but 1994 evented) I found out that it can not be fitted because of the skid plate and Husky winch positioned where the second intercooler is supposed to be mounted.

I have the unit available for sale if you wish (it was bought secondhand, it is an Allisport made one and is for 300Tdi Discos but it is the same for 200Tdi engined ones also)

Take care
