Dinan 4.6L Dyno - Finally
I finally dynoed my Dinan s3-r while at the track today. We also did a dyno on a stock 2013 e92 m3 immediately afterwards to act as a baseline. Both cars on 91 octane.
I still have plans to bring the S3-R to Mike Benvo at BPM to protune it.

That's so nice, so smooth.
It actually look similar to graphs of before/after supercharging. Can't wait to see what Mike@BPM can do to it!

That's some pretty awesome gains. At first I thought it was the dyno jet reading high so I didn't pay much attention to the numbers, but then I realized the stock m3 reading was pretty low.

Curious to hear your thoughts on the difference on track? Any Lap time changes, section/ corner speed data from when it was stock?
Tx!

We did do some highway pulls on the way home from the track and the Dinan s3-r was pretty neck and neck with a FBO E60 M5. Thanks man |

Depending on the dyno. 330-350 whp is about the average that I've seen. Depending on when they did the runs (before or after the track day), the car might have already been pretty hot and pulled timing a little. But if so, that was presumably affecting both cars.

The dyno was reading a bit low. It is running a little lean down low. We dyno'd after lunch. The cars were idol for about an hour and a half to two hours. Stroker was dyno'd first, then the stock e92. |

That's an amazing delta against the other M3. Can you get a dyno also at Alexshop? They have a number of stroker dyno's including a Dinan motor that only made paltry gains. This is an opportunity to see how yours compares, which I'm sure will be much better. Cheers.

Wow. I'd love that power on track.
Same wheel/tire combo on both stroker and stock? Light weight wheels on Hoosiers will show higher numbers.

Stroker had HRE R43 18X11 ET22 w/ 275/35/18 R888 and the stock car had 19" OEM Competition wheels and tires. Last edited by ilikebmxbikes; 02-17-2015 at 12:37 PM.. |

Every dyno will make different numbers depending on the manufacturer and the settings the user has set on it.
Dynojets tend to read a bit higher than others like Mustang dynos. The Dynojet is an inertial dyno, not dynamic load bearing like the Mustang. To compare horsepower between cars, the cars needs to be run on the same dyno in the same location. In this case, it looks like the S3-R has some great gains over stock!
