I never knew that they had to change turbo's as well as tyres! That's hilarious and ridiculous at the same time. LOVE video's like this, that engine is legendary. Has anyone ever figured out on a modern dyno how much HP was output? I suppose the parts are not available these days to run it in the same trim as a Q session in '86.
@@alexjohnward Good point. That stuff is likely not around either and that is probably for the best! I can think of the Adelaide Quali footage from '86 and the black smoke that puffed out the back of Senna's Lotus as he turned up the boost to full to begin his lap. Have to say it looked epic tho haha.
Cool content thanks for bringing it to us, it's brought back great memories for me. I was lucky enough to go to the Benetton Factory in Station Lane around 1987/88. They had one of the old B186 Chassis with BMW Monster in it as well as the B187 with the Ford V6 complete with PopOff valves. Great memories Thanks Alex.
I think 5 bar is actually 6x atmospheric pressure. When people talk turbo engines, the boost is measured above static atmospheric pressure of 14.7 psi. So 5 bar of boost *above atmospheric* results in an absolute manifold pressure of 88.2 psi total air pressure.
No evidence of that whatsoever. BMW were unreliable 1984 on and not exactly bulletproof prior to that. An overrated brand who only ever won races in the back of British chassis and who build overrated, poorly engineered and unreliable road cars.

Doesn't BMW claim the most powerful F1 engine also?
There's only one way to solve this...
FIGHT!!! Harry Hill enters....

They also ran very horrible fuel that probably isn't very legal these days what with emissions and all that

Paul Roche from BMW would like to disagree!!!
He would love to, but he can’t because there is no way of measuring it 😂
@@BrundleBTW apparently the M12/13/1 from 1986 made 1,400hp before it exploded on the dyno.
@@nnoddy8161BMW couldn’t measure the power either
Awesome.... like we went backwards; today's F1 cars are so boring in comparison....

Fantastic video! Love these stories of classic race cars!
BMW had a more powerful engine in the Benetton
Both manufacturers claimed to have the most power
In qualifying trim, yes. In race trim, the 4cyl BMW, the V6 Ferrari & the V6 Renault produced much the same power.
You are about 200 to 300 HP shy of the BMW I4 iron production block there Frenchy. Nice try.
1500 was also a guess.
@@RHBTurbochargers yes I would say it was more like 1,300bhp at best as they ran a single turbo to 5.3 bar

“Frenchy”? That’s a bit xenophobic, isn’t it.
Interesting that renault has kept the same strategy of the engine lasting 3 laps over recent years.
😂
So how many p.s.i. is 5 bar of boost?
72,5 psi
