This Porsche 962 Has One Of The Greatest Turbo Wastegate Noises Ever

Do you like the STUTUTU of a ridiculously massive turbocharger? Let your ears melt with delight at the sound of this on-board Laguna Seca footage

After on-board footage surfaced from a Porsche 908 competing at Laguna Seca last week, more wondrous footage has surfaced in the shape of this visor-cam video from the cockpit of a Porsche 962 endurance racer.

The heavily-turbocharged flat-six racer was once driven by British driver Derek Bell and could be tuned to upwards of 600bhp, bringing with it one of the greatest turbocharged orchestras of all time.

Damn Michael, you work for a car enthusiast blog and don’t know the difference between a wastegate and a blown off valve…

Sounds like my old Renault 5GT Turbo

THIS THIS IS A F**CKING JET

This is compressor surge/flutter. A wastegate navigates exhaust gasses from the exhaust manifold into the downpipe (or straight to atmosphere, called screamer pipe) to regulate boost. When max boost is achieved the wastegate opens and lets exhaust pass around the turbo and regulates how much exhaust gets into the turbine housing. You will not hear a wastegate when it routes back into the exhaust, when it vents to atmosphere you will hear the car get louder when it opens as in: bwaaaaaAAAAAAAHH. A blowoff valve will make the well known PSHHHHH sound, this car doesn’t have one (very normal on racecars) and so you get the SUTUTUTUTU surge/flutter. Educate yourselves CT.
