Most likely supercharged. Herrod motorsport get about 340kw's out of their packages, which include supercharges, sounds like an animal! Damn those EL GT's are sexy lokking cars, shame it was such a let down to ford, it claimed to do 200kw's when in fact it did much less, can't remember how much exactly.
My mates brother is supercharging his EL SVO, other than the GT, this has to be one of the best looking aussie fords ever built. Can't wait till it's on the road.
