Harvey Steinbacher
2006 Mustang GT

Like Chris Cruz's GT/CS, we also had a chance to see Harvey Steinbacher's '06 GT in action before the KOTS. Tech Editor KJ Jones was the first staffer to put his eyes on the car at the 2011 NMRA Milan race. He relayed a couple pictures and a quick rundown on the car; I was able to see it in person and watch it fly down National Trail Raceway at the Columbus NMRA race.

David Bachota from Bachota Performance built the car for Harvey, who simply wanted a fast car he could drive on the street without the headaches associated with having a fast car. He didn't want to constantly work on it to keep it reliable. We'd have to say David delivered.

Starting with a Tungsten GT, the car has featured four different power-adder combinations. Its current Vortech V7 supercharger has been on the car for a couple years now, as has its current factory Saleen-built 302ci Three-Valve engine. Dave and Harvey have continuously improved the current combination over the last 3-1/2 years. Instead of an air-to-air intercooler on most conventional street supercharger systems, David custom built a 7-gallon, tig-welded aluminum reservoir/ice chest for the spare tire well. Custom -10 supply and return lines featuring dual pumps feed chilled water to cool the air charge before it enters the engine. Plus, a 400-cfm fan is mounted under the intake plenum for additional engine heat-soak relief.

The battery was relocated to the trunk, mounted upside down under the rear deck for space savings and weight control. The car's eight-point rollbar features removable doorbars and rear bar to make the car's street life easier to live. There are also remote mounting locations in the trunk for the discarded rollbars should they need to be relocated on the fly. The GT features strobe lights for when Harvey takes the car to shows and cruise, along with a radar detector to make sure he gets to and from those events without a reward for excessive speed.

When it was time to take Harvey's GT on the Ride & Drive, it was no surprise the car was easy like Sunday morning. Since it makes use of the factory 5R55S with a Circle D converter and easy-to-use TCI shifter, driving was easy as dropping it in D and going.

Even though the car features Kirkey racing seats, they feature the optional padded seat cover so it was still comfortable. Plus, David was able to retain the power seat function with the Kirkey, which was really cool, making it easy to find a comfortable seating position. The car features nice Auto Meter gauges and a Speed of Sound gauge pod, and we always like them.

The car was easy to drive, but with the Kirkey seats, it teetered on the brink of being a race car masquerading as a street car. The overdrive function was on a button, but the worst part of the car was the brakes. In my notes, I wrote that they made "a lot of racket." That's kind of an understatement--they were rather loud. However, David said the brakes on the car were the only ones available at the time. The button for the overdrive really wasn't that big of a deal on the Ride & Drive, but the brakes, well, they were another story.

Otherwise, the Vortech-supercharged Three-Valve ran really strong when put through its paces, but that was no surprise since I had watched David run deep in the 10s at the Columbus NMRA race. With all the excitement over the new Coyote, the Three-Valve has been kicked to the curb, but Harvey's car helps restore some respect.
