I have a Chausson based on a 2.5 TD Ford, 1999 vintage. Which means no chip. TB Turbos have suggested an intercooler to boost performance. Has anyone else had an intercooler fitted and did it make a difference?

correct me if I am wrong, Confused

but I was under the impression that the intercooler is a way of taking pressure/heat off the turbo which although improving the flow,not necessarily giving a noticeable boost as such. considering the extra cost is it worth it.

No, intercoolers cool the air therefore making it more dense so that you get more air into the cylinder and therefore improved combustion and additional power.
Haven't had one fitted but do notice a difference in power and fuel compsumption when I blocked the intercooler with mud on my diesel jeep.

TB turbo have a pretty good reputation. If they say it will boost your performance then it most likely will.

Will cool charge air, so will get a bigger bang. TB turbos seem to know the stuff. Trust them. H

When the air is compressed it gets hot. This has two disadvantages. The air is less dense so you get less into the cylinder. This is working against the supercharger and so not helpful.
The other disadvantage is that the efficiency is greater if the air going in is cooler so you should do more mpg.
Whether the effects are large enough to matter TB turbos are more likely to know.
I would ask if they can give any figuresbefore ordering.

Thanks all. We're off for a month or three very soon and I'll ask TB for more details of what I can expect when we return and before deciding what to do. I really could do with some more power but it ain't exactly cheap!

A further thought: If an intercooler does have the expected effect why was it not installed with the turbo? After all it is usual to put on both, they normally work together and I would think that the turbo cost much more than the cooler. Perhaps your turbo is not giving enough boost for a cooler to help. You can only improve an engines power so much before it is overstressed.
Another reason to get the figures before you hand over the cask!.

the addition of an intercooler or the increase in flow of an existing intercooler will almost certianly increase horse power, its one of the old favourites for turbo charged engines of all sizes and types.

As a rough guide, for each degree C you cool the charge air, you will gain one BHP. Therefore if the intercooler pulls the charged air temperature down by ten degrees, you have another ten BHP. It all depends on pipe length, positioning the intercooler close to the inlet manifold, and a good flow of cold air through the intercooler, on how much you gain.
