Can a few of you veterans out there please offer feedback regarding this dynograph?
This is new to me, but I am skeptical here. (IMG:style_emoticons/default/confused24.gif) Thanks! Mike in Munich Attached thumbnail(s) |

You need to richened the mixture. A dyno run is wide open throttle
Wot needs to be 12.5 ish on a 914 at redline Richer as it is building up to redline is ok. But running a car lean at redline is very bad and will lead to a failed engine |

But running a car lean at redline is very bad and will lead to a failed engine Redline is at 5600. Apparently I won't ever be taking this thing over 5000 and if I use a higher octane the burn will be slower and cooler as well as partially compensate for the current AFR (with 87 octane) being a bit leaner than your recommendation. For use as a daily driver I think I should be OK with the AFR at 13.5. No? I will test the car with different octane ratings and perhaps buy a sensor to measure the AFR. If I do I will post the results. It seems to be debated as to whether octane ratings affect AFR significantly or not. As far as heat, this car seems to run very cool, generally under 175 F iirc. Is this TOO cool? It has an extra oil cooler and a deep sump. M.i.M. |
