It's considered a "SuperCar" of sorts -- base GTO offers the 2.5L Ford V-6 (Duratec) with twin turbos, and the GTO3R with the 3.0L propels the roadster into sub 4-second range for 0-60, top speed of 170 mph, and a lateral accel of 1.2+. The weight is a key factor -- around 2400 lb.
That's right -- I almost forgot! First, I need to seal-off the self-made airbox hole and re-route the the air from the original inlet and stick the sponge in there. If the evaporative cooling works, I may consider a reservoir and a maybe a turkey-baster mechanism to wet it down without popping the hood
