Brabham BT52 F1 Turbo in Action - BMW M12/13 1.5L 4-Cylinder Engine Sound!

This short video is about a 1983 Brabham BMW BT52 F1 car I saw and recorded during the 2017 Goodwood Festival of Speed.
Designed by Gordon Murray it features a turbocharged BMW M12/13 1.5-liter 4-cylinder engine which was able to produce around 650hp at 9,500 rpm in race trim (around 800hp during qualifying) and 450Nm of torque.
The BT52 was driven by Riccardo Patrese and Nelson Piquet who won the 1983 championship with this car.

4 cylinders but sounds way better than the v6 turbo we have nowadays

[@rms4455]

I4's in general usually sound better than V6's IMO, but the modern V6 Turbos in todays F1's still sound amazing in person

[@GREGALBU]

V6T can still sound good though, like the Lotus 97t

[@rms4455]

Of course, I don't think there has ever been a bad sounding F1 car

[@TheChazas]

The actual F1 have tons of restrictions, it could easily sound way better, yet hearing them in person is not that bad at all.

Hey Bozzy. Those things sound very laggy initially, but when the boost hits, hold on tight. I bet those cars are frightening as hell to drive at full tilt. So much power from a 1.5L it's almost unbelievable. Thanks for continuously pumping out the great footage, sir. Cheers!

[@geertdewilde8582]

Those sensational claims about 1500bhp of the engine in the BT52 have been copied over and over. But they are incorrect. This car from 1983 had "only" 850bhp in qualification and 650 in the race. But by 1986, the BMW engine was capable of a theoretical 1400bhp in qualifying in the Brabham BT55 and the Benetton. Race and qualifying reports by Murray Walker and James Hunt can easily found on KZbin and confirm this. If still in doubt, just check the wikipedia page about this matter.

@@bulversteher Were do you have these figures? That thing was estimated to have around 1500hp, however nobody knew for sure. After they actually could measure the power they figured that the engine was capable of 1450 hp. The engine had over 1000 hp on qualification labs and around 900 hp on races.

[@bulversteher]

Wiki, ultimatecarpage and even the description of this video. Formula1 com states "could approach 1,000bhp in qualifying trim". Careful with not mixing up different engine evolutions. Power exploded in the early 80s and peaked in 85 and 86 with the M12 in the 86 Benetton. Look for the 86 Adelaide Qualifying video. The engine revs higher and sounds and smokes like a lot more boost there.

[@eamh2002]

On Wheels You can hear the driver in this video hitting boost and spinning wheels then backing off instantly :D Way too much power for this track to even show off..

[@bulversteher]

One thing that could very well be is that they actually put a more powerful evolution of the engine into this car where it originally never was. Still, 640 hp on a 540 kilo is probably enough to make it spin up like that anyway :)
