What's with the ghay music ?

If I get time I will cut out all the carp violin playing and but a proper kick ass sound track on it

Dizzy Rascal bonkers would be apt

If the figures are true that is pretty special. Now they just have to improve the car to the point where they could use that level of power.

Building a turbo engine to that power (relatively speaking) is straightforward.

Getting it to last more than 100 miles before grenading and being driveable without lag from hell... now thats the tricky part.

Aparantly it's supposed to be doing something very clever, some new tech, it's very lean burn and the exhaust gas temp is 70% lower than normal

Interesting... however the fact remains that you can't dramatically increase the rpm on a turbo car (ok, you can but it's hard).
So what they have done is effectively nearly triple the torque groing through the engine. Doesn't matter how efficient the turbo is or anything, it's the end result of the new tech.
It can be done as the tech is quite old but reliability is the main issue.

It's some form of lean burn technology combined with a chargecooling arrangement that lowers the intake temps to -20°C .

Basically the shape of the pistons and a specialised intake system allows them to run the engine at a much leaner mixture process that is supposed to be so efficient, that it reduces the burn temperature so dramatically (exhaust gas temp figures of 590°C, compared to 1200°C of a normal engine of this power level), that a radiator is no longer needed .

The intake is what intrigues me the most, as it looks like it is this that drops the intake temp to -20°C. Obviously this must take a large amount of energy to achieve as it must be some sort of refrigeration unit.

from a response on my post on evo about it

That's some mighty fridge!
The great thing about heat is that it's so predictable from a mathematic point of view.
If you say have ambient temp of 15-20c and with forced induction the temperature will increase. Basic thermodynamics - doesn't matter how you actually compress the gas the temp will increase.

Say the compressed intake charge has a temp of say 50c... To get it down to -20 at the rate that it'll need to be cooled would require phenomenal cooling capacity. I suspect that at least 60% off the power would be powering the fridge!
