The parts required to convert the Supercharger to running a chargecooler (water-cooled) rather than an intercooler (air-cooled) have started to arrive. The first item was a Subaru Legacy Chargecooler:


This will cool the air coming from the supercharger before it goes into the plenum chamber. The second item to arrive was a Fiat Cinquecento Radiator. This will be used to cool the water running through the chargecooler which in turn will cool the air passing through that. The radiator itself is quite compact and very lightweight being an aluminium core with plastic end caps:



The third item to arrive was an electric water pump from a VW/Audi which will be used to circulate the coolant around the chargecooler system. All these purchases so far have been via eBay. The only other items required for the conversion are some silicon pipes to transport the coolant between the radiator and chargecooler, and for getting air from the supercharger into the chargecooler and back out into the plenum.

The Nippon Challenge website is now up and running and an interesting selection of cars has begun to form within it. This bodes well for a mixed field of car makes, models and performance levels. Visit www.nipponchallenge.co.uk for more details.
