Scott Cook lives in Westerville, Ohio and drives our turbo project car - a 1998 Grand Prix GTP. We started on it in January 2003 and it was unveiled three months later at IDD III. The first day at the track was a complete success. First pass of it's life was 12.044, and the fifth pass was 11.634 @ 119.97 mph (1.852 60'), which set the all-time 3800 FWD quarter mile record on it’s very first day at the track. The INTENSE team then continued raising the bar by beating their own records, and holding onto the 3800 FWD quarter mile record for 29 straight months (nearly two and a half years)!

This car has the distinction of having been the first ever 3800-powered FWD vehicle to exceed the trap speed barriers of 120 MPH, 125 MPH, 130 MPH, and 135 MPH. It was also first to break the 3800 FWD quarter mile barriers of 11.50, 11.00 and 10.50 seconds. As the 2005 race season began, we were closing in on 800 Horsepower, and planned to break into the nines. This goal was accomplished in October 2005 with a 9.996-second pass, and our team is convinced there’s much more where that came from.

The car was built (and is NHRA/IHRA legal) to run as fast as 9.00. Here's the basic list of modifications:
