I like the torque 5,608,312 lb/ft at 102rpm, not bad, but only 108,920 bhp hardly enough is it.

I filmed a series a few years ago with Robbie Coltrane, called 'Coltranes, Planes & Automobiles' for Channel 4. Apart from racing around the Nurburgring in 4 supercharged SSK's, we filmed inside the biggest diesel, being made in Trieste. These are AMAZING engines, but would seriously upset the weight distribution of the Porsche!!!

No doubt calculate the weight distribution with 2300 tons over the rear wheels.

Either way very cool.

Yep, imagine the pendulum effect of lifting off in mid-corner with that sucker at your rear!

Would you need to adjust your tyre pressures?

Consider a modern high by-pass commercial jet engine:

Approxiamtely 100,000 shaft hp (it's actually more)
Weight ~18,000 lbs

Not a bad power to weight ratio.

Would it sound as sweet as the 964? That would be my question...

How do you convert thrust to shaft horsepower?

Is that the power required to drive the fan?

Yes - the hp required to drive the fan.

Take off the fan, add a couple of booster (low pressure compressor) stages and hook it up to your favorite gearbox. That's how they use them in ships etc. Quite elegant, if you can live with the noise...they scream and excite every bloody frequency known to man (blade passing frequencies of all the different stages).

Regards,

Geo

Alternative just get a 964 turbo.

Turbo winding up as you go over 3000 revs to the red line is the reminder of a Plane just as it turns on the thrust for takeoff.

Brings a smile to the face of driver every time, fear the passengers!!!
