Go to the race track. Super Street Outlaw class guys running turbo's, or ProChargers, getting insane horsepower with an intercooler.
Last year at the World Ford Challenge, they had to drive the cars on the street in stop and go traffic to qualify for the class..lol..... These cars were fast, running 8 seconds (real 8 seconds, not Fast and Furious junk) at 170 mph, on 10.5" tires
You could easy street a 900 Hp Cobra with an intercooler, if you have the correct build to the engine.
