Really interesting, thanks Toby.

Would the need for such water injection be negated if they fitted properly expensive intercoolers (genre Secan, etc...?)

As far as I heard, the GT2 RS was supposed to be put on the market with 650 hp only. Then came the 720S... Smiley

The GT2 RS engine is basically the 991.2 Turbo S engine, so you can imagine where the issues lie. 

They had to make a track proof engine with 700 hp out of this.

The water injection was apparently the only way to achieve the power they needed without compromising performance, reliability and...trara...EU emissions.

The water for the 2RS is spray on coolers to maintain acceptable temperature. It has nothing to do with emission. Let’s wait for a bit of a time before calling the engine bulletproof. For now, these cars are on sale or collecting dust in garage because the owner thinks that was rare angry 

Thermodynamics always have to do with emissions... Smiley
