So i tested the pressure of that 50mm fan. It is rated at
50mm=715W MAX in 25.2V. 30 amps..
I tried it on 5s it made about 1psi with no flow... BUT it got so hot that it would melt down on 5s so it's irrelevant that it made 1psi.. I could do more testing but i dont see there is any point as it...
Not really .. the first set of parts.. the bearing holes where to small the second time they are to big.
for the shaft the first was to big.. and the second to small.
To be honest im not surprised this exact reason was why i originally wanted to get someone local to make it because i could give...
It is slightly better than that PSI because you didn't remove the central hub from the 120mm area... Not that that would change the number significantly. The interesting thing is that the quoted thrust numbers never tell you at what flow rate, it certainly wont be 0 flow rate.
I know them and...
In my opinion ducted fan wont be that good because they are designed to create trust not pressure and flow..
To have good pressure you need a large central hub and overlapping blades..
I bought one of the latter to see what pressure it would give out of interest.
Sooo after a long discussion with them i paid to get it made again.. Unfortunately it's still a pile of junk that doesn't fit perfectly together.. So this was just a huge waste of money.
After complaining to PCBWAY that basically all of it needs to go in the bin this is what they produced on their tolerances.
0.2mm What a complete Joke !
So i got this made by PCBway. it was a fraction of the price than getting it made locally but as i thought china would fail to make it correctly
One of the bearings doesn't fit and i broke it trying to remove it.. Also the counter clockwise thread on the shaft was made the normal way.. not...
Yeah rev hang is unrelated to the E-Turbo.. but the piggie back controller is not as that is required for the E-turbo. So im making indirect progress. I have also ordered my Wide Band O2 sensor. After that is installed i then can get back to spending money on the actual E-Turbo..
I have done a...
I had hoped to retard the timing massively but unfortunately the stock ECU doesn't like a Massive retard and throws a error code.
I could trick the ECU into thinking there is very little air coming through and so it would mostly cut fuel.. im not sure if that would work though cos it might be...
i just received one of these .
This can run in 2 modes.. piggyback mode (stock injectors) or "fuel impant" to allow me to run larger injectors.
Right now i'll just get it going and try to use it to remove "Rev hang" which i hate with a passion
