Michael Carmouche
2011 Mustang GT

After watching his prized turbocharged '03 GT burn to the ground, Lafayette, Louisiana's Michael Carmouche's '11 Mustang GT allowed him to start over, and work on with his son Tristan. "It has been the most rewarding automotive experience I've ever had," Michael says.

The GT's big ticket item is a big reason why we chose Michael's car to begin with. That big ticket item is a ProCharger D-1SC supercharger. In his application, Michael told us the car made 732 rwhp, and we wanted to see it in action.

We almost didn't get to see or experience his car at all. He destroyed a driveshaft right before the competition, but Lethal Performance was able to get him a replacement in time.

Michael's GT was one of the easiest to get in and out of since it still wears the stock seats and seatbelts, and is devoid of a rollcage. The car features a Grant steering wheel, Speed of Sound gauge pod, and Redline Goods (www.redlinegoods.com) shifter boot and E-brake handle.

First things first--I love the sound of a ProCharger. Nothing strikes fear or causes jealousy like the sound of a centrifugal supercharger. The ProCharger D-1SC with blow-off valve and wastegate made beautiful music together on Michael's GT. Of course, since the ProCharger relies on a crank-driven belt and rpm, the car's power delivery is linear.

If I had to choose one car to take home with me, it would be Michael's GT. The tune was spot-on, the McLeod RXT clutch was perfect, the factory Getrag MT-82 six-speed shifted great, and even though the car featured a stock head unit, it was bolstered with Infinity speakers to enhance the listening enjoyment. The car was quiet--thanks to the SN-10's refined nature, it was able to keep the ProCharger from overtaking the cabin.

With Michael's car, you can have your cake and eat it, too. If you want tunes, turn up the radio. If you want the whoosh sound of the ProCharger, drop down a gear or two to bring up the revs...same with the exhaust. If you want a quiet ride, turn down the radio, drop it into Sixth gear, and cruise.

If Michael wanted to hand over the keys, I would opt to switch out the H&R Race springs for the company's Sport versions. The car's ride was a little on the bumpy side, and H&R's Sport springs are a better option for the street.

I was surprised Michael's GT didn't finish KOTS with a higher score, but his car didn't make the power needed to do well in the Horsepower category, and the car doesn't transfer weight at all so he didn't do well in the Drag Race category either. However, Michael's GT scored well in every other category.

Michael should be proud of how well his car stacked up in the KOTS.
