So I have been playing with adding resistance to the cht to bump my mixture. Messing with the mps was not getting me to where I wanted to be I wanted something a little more global. Anyway, bought a 10 dollar Bluetooth relay. Set it up so one channel was clean the other had 50ohms resistance in it. As I am driving I can switch back and forth and watch the results on the cht and AFR. 50 is really working well (this is all in addition to my 250ohm found on 73s). Now I have added another 20 ohms to the alternate so the relay will switch between 50 and 70. It ain't pretty but it's only for troubleshooting.

Somewhere out there online is a doc, drawing and pictures of the aero dynamic testing done by a member many years ago….
I’m recalling a set of tests to measure air going into the engine lid, along with temps with and without the rain tray…lots of good tests. Tray or not makes no difference. Side vents, like the Boxster, would probably work great. I recall getting air into the engine lid was actually harder at higher speeds. Might be worth a hunt to go find old info on 914 aero dynamics |
