Very interesting look at what Simple Digital Systems has done with Subaru EJ22T engine for aircraft use. Some very good engine and head tech. SDS specializes in stand alone, programmable fuel injection for automotive, marine and non-certified aircraft applications for street and track.

Where did I see this? Though I do wonder what reducing the size of the radiator hoses does for cooling.

course this is awesome: http://www.sdsefi.com/air31.htm

It's just amazing what some of these guys can do, and the awesome fabrication.

The constant problems he was having was engine cooling and intercooler efficiency. Makes you wonder about sizing down those radiator lines. Interesting how you have to expel about twice the amount of air taken through a radiator for it to work properly (<-sp? ).

i wonder why he did it then.
