QuickSilver ‘Rev-Off’ – Wilton House Supercars – August 14th 2011- Results

QuickSilver Exhausts were proud to be Sponsors and to join the judging team for the ‘Rev-Off’ Competition at Wilton House on the 14th August - the brain child of event organiser, Jay Broom it was an enormously popular part of the day. The spectators were so dense that the judges had difficulty in moving from car to car as you can clearly see from the video.

Following the excitement generated by the event video and due to popular demand we thought we would publish the full results of the competition.

So here they are...

Putting Decibels into context:
Sound exceeding 95 db can lead to permanent hearing loss. Pain begins at 125 db. Even brief exposure to 140 db can lead to immediate permanent damage. - The ‘Rev-Off’ has only one rule – ‘The loudest exhaust wins’

RESULTS IN REVERSE ORDER

TVR Typhon Black 109.0 db

A great sound from stereophonic exhausts tips with the owner exercising rare mechanical sympathy.

Aston Martin DB9 Black wrap 110.2 db

V12 engine – A well-known Pistonhead’s car beautifully presented in matt-black with a nice smooth sound but, arguably, too flat - lacking the variation in note of some of the best aftermarket exhaust systems. A very popular entrant that got a special shout from the crowds as he left later in the afternoon.

Porsche Carrera GT Yellow 115.0 db

V10 engine – The closest sound to Formula One this day, with all the shrieks, howls and gulps – only lacking ultimate volume.

Knowing the previous scores, the owner cheerfully turned the stereo up to maximum to try to add to his number and in fact he could have scored higher if he had blipped the throttle more vigorously. Showing quick thinking he used the opportunity to promote a local band. (see video)
In the end, the turbine smoothness of this engine at maximum revs did not cut it. 115 db is still bloody loud though!

Dodge Viper Road Car Red 117.0 db

V10 engine – At 8.3 litres, this engine was biggest in the competition and often said to be originally a truck engine. So what? - this model has proven to be formidable competitor in endurance racing with it’s truck-like torque and reliability. It’s side-exhausts meant that the judges had to adapt their measuring technique, positioning the meters a metre away from the exhaust tips, as with all the other cars. A unique sound, again with lots of American Bass, but this huge engine’s inability to rev meant it was never going to sing like Pavarotti – more like Paul Robeson.

Aston Martin V8 Vantage Volante Light metallic blue 119.3 db

V8 engine - This car belonged to well-known Pistonhead and video-blogger ‘Shmee’ and was an enthusiastic revver to open the contest.

Lamborghini Diablo VT 6.0 Maroon 120.0 db

V12 engine – Another Diablo with the big V12. A relentless riff like Metallica - and a crowd pleaser.

De Tomaso Pantera GTS Grey 120.3 db

V8 engine – A proper old-school American V8. This was an old Rocker. Not high-revving so loads of bass.

Very popular with the onlookers but, with 1970s carburettors, it was running extremely rich and the acrid fumes of this exhaust caused the crowd to cringe. A great sound and certainly the most fragrant - but not enough volume for this contest.

Aston Martin One-77 Maroon 120.5 db

V12 engine – Modern twelve cylinder engines can often sound flat, lacking the character of their V8 or V10 counterparts. Not this One-77 though. A sophisticated melody that rose and fell like a soprano. If there had been an award for sound quality this would be the winner. And many thought it the most beautiful too.

As the cars left, the drives of Wilton House were lined with hundreds of people – enthusiastic families shouting ‘REV IT!’ to all the cars – who were happy to respond. This One-77 left hand-in-hand with the Green Aston Martin V8 Vantage. As they drove through the dense crowds urging, ‘REV IT!’ they could be heard revving-it-out for some distance - making a great sound together.

Koenigsegg Agera White 123.6 db

V8 engine – With twin turbochargers generating some 940 bhp and over 1100 nm of torque this Koenigsegg had, by far, the biggest numbers. The original exhaust system is of a secret patented Koenigsegg design and manufactured from Titanium and Inconel to provide a thunderous growl together with the ability to meet emissions and sound regulations. The aftermarket exhaust manufacturers would approach this at their peril.

With remarkable technical and cosmetic detail in every component this car was art on wheels. You can imagine this on ‘Antiques Roadshow’ in 200 years. Though a serious number, the sound volume was insufficient in this company. The Koenigsegg won the award for Best in Show.

Lamborghini Diablo VT 6.0 Yellow 123.8 db

V12 engine – A huge sound from a big engine . These Diablos are real Heavy-Metal machines with a presence to match. They can be felt as well as heard.

Lamborghini Gallardo White 124.5 db

V10 engine - This was an early model and did not disappoint with a high-revving V10 howl - later cars have a different firing order and lost some of their shriek

Aston Martin V8 Vantage AM Green 125.4 db

V8 engine – This car had been meticulously tuned by scientists to increase engine output to 475 bhp and enhance all the sensations that an enthusiast enjoys from a Supercar.

With a sound that ranged from deep to high and, at risk of stretching the metaphor, this car sang like Mel Torme - with a range that most could not match. Of all the cars here, this was the one that you might realistically take home and use daily, enjoying every journey.

TVR Tuscan S Dark Grey 126.3 db

Straight 6 engine – 400 BHP from this 4.0 litre normally aspirated engine. A ripping 6 cylinder blat.

Lamborghini Gallardo Green 126.9 db

V10 Engine - This car was the winner of the ‘Rev Off’ last year and was a contender again. This generation of Gallardo is regarded as one of finest sounding cars on the road. Lovely Green and Black and outrageously loud but with a great range of notes and one of the judge’s favourites for the quality of sound. This car was the Tenor that would sing all the tunes on the most spirited drive. Though the loudest so far, it was eventually overtaken - though it did win an award for Cleanest Car of the day – and deserved it.

Lamborghini Diablo Metallic red 127.3 db

V12 engine – This earlier Diablo was a very determined entrant. With the engine bouncing off the rev-limiter, particles were expelled from the exhaust stinging the judges - who feared for the safety of the engine. With a deep frequency of sound like radiation, the waves could be felt through bystander’s internal organs. This car had undoubtedly the most presence of any entrant and one of the judges wanted to give it the award on the spot.

Dodge Viper GTS – Race Car Red 128.0 db

V10 engine – This was a Monster … prompting the judges to warn the crowds to protect their children and cover their ears. The bass and volume at tickover gave notice and weren’t wrong. Way past the threshold of pain it turned a whopping 128 db. With sheer consistent volume from it’s crisp race exhaust this was easily the loudest so far and was giving high meter readings without blipping. The fly-by-wire throttle meant that the driver had to work from under the bonnet – his ears must be ringing still.

and finally the winner...

Ferrari Enzo Red 129.0 db

V12 engine – Of all the entrants this Pistonhead was the most determined and was odds-on favourite before the judging even began. Remembering the 6 Ps ( prior preparation prevents piss-poor performance ) a special exhaust had been produced to provide just maximum volume. And was it loud ! Judged twice, one of the meters briefly showed 133 db – too close to the danger zone. This red Ferrari was a very popular winner – Lord Pembroke presented the ‘QuickSilver Exhausts Trophy’, a bulb-horn from a 1910 London Taxi, restored and engraved for the occasion.

(The horn registered 105 db on the meter.)
