they are made by PWR, barrel type air to water intercoolers. im building a twin t-70 setup and im thinking maybe two of there 6 inch units, one after each turbo before i y the two pipes together going into the maf, and then intake...what do you think?

The only info that I have seen is in the thread below. It looks like it could be a really good idea if you would want to run an air/water because it would be able to fit nicely. There is a photo of one mounted down towards the bottom of the first page.
