We took the eurocompulsion.net 124 to the dyno today to get some baseline numbers.

A few notes: this car is an automatic so it's numbers are a little lower than we typically see from this engine in cars with a manual transmission or a DDCT. That makes sense as it takes more energy to spin the Japanese slushbox and driveshaft. All and all it's pretty good though, it's only down about 5hp from a DDCT and perhaps 10 or so from a manual.

So far, the engine seems to perform normally on the dyno, however you do get a lot of warning lights. Traction Control, ABS, Transmission and the Check Engine Light. The CEL is caused by two codes, both related to the front wheel speed sensors. Once the car was back on the real road, all lights went out, except the CEL which we had to clear through the OBD 2 port.

We have never seen a CEL before from this engine during dyno testing, so that was a surprise. All in all though it went well, data logs showed the car was not pulling power out. Hopefully that continues as we increase the power. The numbers came out within about 5hp of our Auterra Software Dyno which is a good sign.

~140 rwhp is not bad considering being the automatic.
I agree, and I'll add that the fans in that dyno shop are pretty weak, and it was in the high 90's when we did these runs. Add in the fact that it's an automatic, and I think the results are pretty good. Based on my experience dynoing this engine, I suspect that a stick shift car with better fans on a 70F day would be in the low 150s.

I suspect a manual transmission on a 70º day will be more like the low 140s.

Maybe, in any case we will soon find out. I am basing the low 150's numbers on the assumption that the Mazda transmission and diff are nearly as efficient as the Fiat 500 transaxle. Maybe they aren't I don't know yet.
