Funny im doing this NOW because there is "no tomorrow" for "all motor" engines.. Thanks to government rules they will / are all Turbo, hybrid or electric.. So it's a case of now or never... and i've always dreamed of this so would like to ticket off my list... E-turbo ..done.. Oh and if i can...

Oh the other thing is that if YOUR at 100% duty if you didn't have enough "power" you could get more power out of the motor by increasing the load "motor slow than impeller" If your already at 100% and dont want to change the gearing then you'd have to increase voltage or KV which both cost...

Somewhere we were having the discussion about Efficiency and gearing. I was inspired to investigate that.. To be honest there is little info about it. However it seems that a highly Loaded motor which would be a slow motor turning the Impeller faster would be Far less efficient that the...

i think your missing the point... Bigger engines need more Air flow than a smaller engine.. Big engines the P2 will suite but for a small engine it wont.. This is not about a small one driven hard V a big one driven slowly... It's about the right size blower for your engine. For example WB...

i dont think they are comparable personally .. you are doing a system for small capacity engines.. While Alex is doing something for much larger engines... It's doubtful many if anyone with a small engine will use this p2 charger... So i think both can co exist

Well if he wants to find out the cause he has to try some things .. Also like others have said he should try removing the current limits altogether / make them beyond where they will get hit... Because my understanding of how the limits work you'd expect them to cause oscillations ...

well looking at it the boost gauge it's all over the place too.. Im interested in the hole for the air coming out it is pointing down into the board with a slight gap? Im guessing that it's causing some thrust /and backpressure causing the osolation. I would try 1) Pointing the outlet UP where...

My side of things were finished in December but since then i have been unable to find anyone to machine it up for me... I emailed some places in December and only one replied telling me that he'd get back to me in January .. I chased them yesterday and still nothing. To be honest it's prebaby...

The LTO i was referring too were smaller than the lifepo4 cells you were suggesting at 32145, though you will need more cos of the lower voltage. It's kinda hard to to avoid spot welding.. cmoalem bought the pouch 123 cells and they seemed good enough (though if the aim is less sage you might...

From a simplicity point of view and having screw terminal the only cells that i have found that are viable are the 6ah LTOs that i bought that has super low IR's and thus practical.

Do not buy those... these are old cells . A123 does not make these anymore and haven't for years.. ALSO their specs are trash... 8m ohms is HORIBLE .. much worse than what you have now with your LTO's

Something ruffly like this. The coloured part will increased and decrease. But animating that is a huge job and i want to get the screen first cos i know there can be a big difference between theory and reality. I will probably also add a wave for page to display this data too ( graphs )...

is this posted against the wrong topic ?

Since i have a dumb ESC im intending on monitoring the voltage and simply increasing the "power" as the voltage drops to achieve the same thing ( constant ish rpm irrelevant of battery voltage )

i haven't heard back about getting my stuff machined. i will hassle them in a few days time ( feb ) In the mean time i have been looking into UI's again and i know i said i was going to use the same ui as my TEC controller . But i think i'll do a new one purely based a nextion 7 inch display and...

i'd like one of these because it is the only one that im aware of that you can control the motor based on Erpm not just percent.. This is useful because you can maintain the same erpm / Boost irrelevant of battery voltage, assuming you have more KV than you need.. Otherwise boost will drop off...

looks good to me

yeah i know what yo mean the TP like min only has 4 m3 screws ultimately holding it together lol

Only mounting it in two places seems a bit risky to me.. but whatever it's all interesting. So what ratio do you have right now ?

Awesome .. are you able to try a 1-1 gearing as well ? so 1-1 ,1-2 and 1.5 for comparison ?
