This owner, Terry (“beefcake”, from Corral.net and ModularFords.com) is reporting high tens with a Vortech Supercharging System with air-to-air intercooler, 4.10 gears and ET Street radials. The Kona Blue GT also benefits from Stainless Works 1-7/8″ headers, and a visit to Evolution Performance for a Jon Lund tune for 93 octane gas. A trip to the dyno showed 528 RWHP and 448 RWTQ at just under 9 psi boost.
Terry’s car on the dyno @ Evolution Performance:
The Vortech System comes with a V-3 Si-trim head unit like the previous 4.6L 3-valve kit, though take note that in the shots of this install include a prototype inlet and does not include the molded intake tube kit that mates up with the OEM factory airbox as seen in previous advertising, and that will be included with the kit. Equally exciting is the fact that Vortech will be offering this system as a limited edition 20th anniversary version that comes completely black powdercoated, and with a special Anniversary Edition Supercharger Serial Tag that will undoubtedly make for a hot collector’s item down the road.
As you see, the track performance claims are well documented with time slips and the videos below. It sure took a lot longer than this to get the first 5.0-liter engines into the tens. Now, we’re living the dream.
