Thing's are not always as they first appear, fortunately. As one Youtube reply would suggest. He also had a high IAT of 92C but after isolating his inlet from the exhaust/turbo heat his IAT dropped t
Indeed. Many of his vids/posts are a bit misleading/partial truths. ( like him claiming he could fit his forged single piece crank with bolted rods in the stock case.....not) Cheers PeteZ
Thought it was interesting re' how the ECU bleeds off boost as IAT increases. Wondering if this is experienced by end users not running intercooler. Also provides turbo timing data. Didn't know about
Hi Group What I find interesting on the 914 is with the throttle about 1/2" or less, the airbox pressure is greater than 44"! When setting up 914 with TCU software, I found that 1/2" or less the wast
It's highly probable the manifold graph referred to in fig 6, p76, is referencing the max MAP baseline which drops dramatically at engine startup. The wastgate rests at full open position when the en
Hi Area 51 Graph 6 on page 7-10 is in fact airbox pressure, not manifold pressure. That would be the pressure before it gets to the carbs. The wastegate is in fact fully closed at idle position and u
In that case the Wastegate switch referred to above is the TCU switch component, and the Nominal Airbox pressure (2atm) would be residual from the compressor function at 1600rpm-2000rpm. As soon as t
Hi Area 51 Yes you turn off the power to the TCU to lock the waste-gate servo in whatever position it happens to be in. There is a series normally closed switch in series with the waste-gate that is
Hello all, Having flown my Europa Monowheel, powered by an early 914 for over 20 years, I find this discussion interesting. I initially installed my engine with an intercooler, however after a few ye
Eric you are spot on. In 2010 I put the TLR46 TCU on my old Rotax 914 and I didn't see the airbox temp on my thermocouple go above 140 C so that told me I didn't need any intercooler as we did on the
That's sound advise; just set it all up as factory advise, and just fly the plane and let the computer do the rest. Guess what? It will work as required Personally, my view toward turbo charging is n
