|
|
Hi there,
Has anyone considered a air/water intercooler for the 931? I've been checking up on it and it seems like a good alternative to the GT style intercooler (problem with heat soak at low speeds, don't have to cut bonnet) and a front mounted one (long piping and space constraints).
Anyone have any suggestions/comments on this? Is it worth the effort?

the major downside to an air/water intercooler compared to air/air is the weight and complexity.
Take a look at the series of articles starting at http://www.autospeed.com/cms/article.html?&A=0084 where they show what's involved. _________________ 1979 924 (Gone to a better place)

The main problem is that there is absolutely nowhere to put it all. It is much easier to just run the air-to-air intercooler |

What does A/C have to do with the intercooler? |

An air/air intercooler might be easier if top mounted but then I would have to cut my hood which I don't want to do (I want a bolt on). Besides, I think a hood scoop plus the NACA duct just doesn't look good.
If I take a small air/air intercooler core and wrap it with a water jacket to become an air/water unit, I should be able to fit it under the hood without cutting. Furthermore, I can route the water lines to wherever I can fit a small radiator. By doing this I will have an inline intercooler with mininal pressure loss and still be able to transfer heat out from the air, through the water, to wherever I can fit another radiator.
I know it sounds kinda simplistic and the details will be a lot of work but don't you think it might be a good alternative since the engine bay is too cramp to put in a large unit but there are small pockets of space around where one might be able to fit a water pump here, a resevoir there, and with water piping everywhere....
I've found a small intercooler core around 7"x8"x2" size and am wondering if that will be able to remove enough heat to actually make a difference.
Another question... does anyone know how much clearance there is between the engine and the hood? Also, what is the thickness of the GT intercooler?
Thanks!
