Re: Smart injection
Hi Richard, yes that is correct, the 74kw version was 'Brabus' only and had sodium filled valves and water cooled charge cooler, improved turbo with different wastegate actuator, bigger injectors, exhaust and TIK and different cam and map.
These engines have been tuned to 120hp, but then they are very stressed at 171hp per liter!!! (The stronger wastegate allows overboosting beyond 1.5bar).
Interestingly the (Suprex) engine was an offshoot of Smarts abandoned Hybrid program and the brains behind it (Swiss Auto) have since developed a successful hybrid powerplant along these lines.
