the dyno's couldnt even handle the power so its not really known, but about 1500 before the big bang.

Where do they get the extra power? Does it have a super-overbuilt top end that revs to the moon? Forged Bottom end? Stroker setup? What car/injection setup did they use? I'd be interested to see how a 1500 HP engine is built using an otherwise stock 2002 block.

I remember back in the early '80s when Nelson Piquette won the championship they were using 1.5l engines but they were turbocharged and used very exotic fuel blends.

i think that they were running dual webers. and probably some sort of free flowing exhaust.

There is a racing version of this motor on display at the BMW zentrum in SC, as far as i could tell, the block itself is a 2002 bottom end, the head is a DOHC with mechanical fuel injection and a turbo that is litteraly 9-10" in outside diameter...

They used modified production blocks. The head is a twin cam design derived from their Formula 2 motor. The Turbo is what gives it the extra punch. Contrary to nowdays popular Detroit tuning philosophy, this motor was actually destroked to an extremely short stroke of something like 66mm. This was done to comply with the 1.5 liter limit for turbos and more importantly to enable the engine to maintain very high revs and move the powerband up to where the turbo is most efficient (8,000-10,000rpms). If you stroke a motor you move the torque and power to the low end and go flat at the high end. Destroking it gives you the opposite effect. Short stroke motors are also much more comfortable at high rpms and maintain lower piston speeds. There is less reciprocating mass. Their drawback is that they make little power on the bottom and in the most extreme cases such as the Formula 1 motor, they make very little power on the bottom and stall if you tried driving them like a street car. Ferrari, Alfa Romeo, and other Europeans have been building the smaller displacement highly refined and tuned motors while the Americans have used the very high displacement strokers tuned less radically.

The GT40 for example was able to clinch 3 Le Mans victories, but even the small block Ford 302 was still 5,000cc compared to the 3.0 liter Ferrari which was its closest rival. It takes more money and engineering to make a short stroke race engine.

The BMW M10 1.5 liter Formula 1 engine is by far one of the most successful, powerful, and reliable of these motors.

The very short stroke of this motor (66mm or so) enabled it to rev very high comfortably where the turbo is most efficient. This is the traditional European philosophy to tuning vs. the stroker Americana - Mopar concept.

Short stroke engines are much more comfortable and capable of handling high rpms vs. strokers. They are less flexible though, but in racing o this caliber flexibility is not an issue since just about any motor in Formula 1 will stall below 4,000rpms.

is that a torpedo on that motor?
