GTP: 1989 Portland IMSA GTP Race Broadcast

August 21, 2009 by Marshall Pruett · 1 Comment 

Spend 97 minutes with Geoff Brabham, Price Cobb, Davy Jones and the rest of the players in the 1989 Portland IMSA GTP race…one that went down in great controversy after the checkered flag was displayed early.

Jaguar’s Price Cobb crossed the finish line first as the checkered flag waved prematurely, and Geoff Brabham crossed it last just when it was scheduled to fall. Despite Nissan’s victory circle celebrations, the win would be overturned and given to Cobb.

While it made for great drama at the time; it’s all IMSA fans spoke about, but the altered outcome did little to sway the championship as the Nissan/Brabham freight train carried onto their second consecutive GTP title.

GTP: Sounds Of Laguna Seca IMSA GTP, 1987

August 14, 2009 by GTP.com · Leave a Comment 

What happens when a 16-year-old Marshall Pruett drives down to Laguna Seca to watch the 1987 IMSA GTP race with a camera in one hand and a tape recorder in the other?

First, he takes a bunch of photos that range from blurry to overexposed. Second, he fashions a hook out of a coat hanger to suspend his tape recorder from the fence on the outside of turn 2, then captures some of the most delightful sounding racing cars he’s ever heard.

More than twenty years later, and with that cassette tape somehow managing to remain intact, I transferred the audio to my laptop, cleaned it up as best I could, and posted it below.

The warbling sound at the beginning of the tape is accurate — it’s a driver pumping the brakes to warm them up, hence the engine note rising and falling. From there, the first big HOLY %$!* burst of sound (at 00:41) is a Group 44 Jaguar XJR-7 streaking by at full chat.

I don’t know all of the physics and mechanics behind it, but the Group 44 V-12 engines had a completely different sound than the TWR V-12s. The XJR-9s and 12s had more bass — they had equal parts Motown Soul and Memphis funk coming from their exhausts.

Group 44’s had more treble and lived at a higher register — they were operatic in the tinny heights they reached. I still grin today whenever I hear this tape.

Take a listen and experience the Jags, Porsche 962, Buick and Chevy turbos, a Ford V-8, and variety of Pontiac and Mazda-powered Lights cars as they sounded back in 1987.
