F1 and F2 Engines[edit]

The M12 was primarily a F2 and sportscar engine. The article just jumps into F1 and ignores the fact that the F1 turbo is a derivative (with its own designation of M12/13) of a much more widely used F2 motor and that in motorsport circles, "M12" refers to the F2 version.78.17.232.6 (talk) 14:38, 14 March 2023 (UTC)[reply]

Who cares?[edit]

This engine was the first turbo to win a F1 world championship. The article barely mentions this fact, skipping several years of F1 racing between BMW thinking about entering F1 in the late 1970s, and 1986. -- Matthead Discuß 07:11, 21 August 2012 (UTC)[reply]

Agreed! This comes up on some of the car pages too, such as the Porsche 917 and the Sauber C9 and Mercedes-Benz C11 where the history of the car seems secondary to its top speed. Flanker235 (talk) 04:59, 21 April 2017 (UTC)[reply]

This page reads as Formula 1 history, very little information about the actual engine ... most of this stuff should be somewhere else

Power claims[edit]

The power claims in this article need to be sourced. Furthermore, the claim that anything over 1,000 horsepower is not accurately measurable is not true. Horsepower is not measured. Torque is measured and power is calculated. Many things need to be known: fuel flow, boost pressure, etc. and this is where the calculations are made. But there's no point making power claims without sourcing them and then saying such claims are not accurate. Check this page:

As long as there are accurate figures for RPM, torque, etc., power can be calculated. We should not be reliant on guesses. That brings speculation into it and we all know where that ends. Flanker235 (talk) 04:57, 21 April 2017 (UTC)[reply]

power = torque * RPM .... what else is needed? I don't see where "fuel flow, boost pressure, etc" comes into it... — Preceding unsigned comment added by 185.147.20.2 (talk) 10:12, 19 December 2017 (UTC)[reply]

Depends on how accurately you want to calculate it. Torque x RPM divided by 5252 only gives an absolute theoretical maximum. It's a handy rule of thumb to filter out the more ridiculous claims. Don't know why I included boost pressure in my previous comment because it isn't really relevant but fuel flow definitely is. A refer you to that link I posted earlier.

why they're not producing these kind of engine's nowadays for normal daily driving?[edit]

I doubt many people are prepared to pay huge sums of money for an engine with a drink problem, power delivery like a delayed-action light switch and a worrying tendency to leak oil through the huge holes left in the crankcase after a piece of overstressed metal cried “Enough!” and went walkabout, but perhaps I'm just being picky… Mr Larrington (talk) 09:23, 15 April 2022 (UTC)[reply]
