225bhp ROFLMAO
Cosworth I believe warranty their crate engines and the MBE ECU which is a quality and proven package tbh.... though the trade off is a little less bang for buck.
The babydoll is 250 HP and no warranty on the engine.
We assume the AR4 has a warranty so it could be the fastest with a warranty.
Maybe Morgan have had too many problems with the other engine suppliers and are trying Cosworth as Morgan's job is building cars not getting too involved in engine development and the hassle of sorting engine maps after release
