These are the results of the dyno testing done on my 1993 SHO auto. The tests were done on a Dynojet 248C at Steeda in Pompano Beach, Florida. Don't contact them as they are very uninterested in anything to do with SHOs. All data is presented in SAE corrected numbers, with the car in second gear.

Run 02, baseline

55MM MAF in stock airbox, no chip. Walker Dynomax cat-back exhaust, Larger flex pipe, hollow cats.

Run 13

80mm MAF, my custom air box, no chip. Same exhaust configuration.

The 80mm unit without a cone filter or aftermarket chip made more power and torque across the rev range.
