@WB projects : so you want increased BOOST at low engine rpms without getting into the surge area: look at the Y Axis ... you want to get a high pressure ratio ... like e.g. 1.8-2 ... then look at the X axis ... you want low engine rpms/(low lb/min or low CFM) ... you want to stay to the right...

if you could spool your impeller up to 50000 rpms ... then this turbo map looks nice ... but not for your small engine! @WB projects

@WB projects ... for your small displacement engine you want a centrifugal setup with such/similar map ... note how steep the red surge line is for low CFM (low engine rpm) (and how "flat" the blue choke line is for higher CFM) I am sure there are similar turbos out there ... but they would...

@AlexLTDLX : With my rudimentary understanding I cannot predict how an existing compressor map gets tweaked as a result of your suggested mechanical modifications. There most likely are "rules of thumb" for that, but we need here a senior with history/experience in tweaking compressor maps of...

absolutely freakin' aaawwwessooooooome 😝

Thanks! downloaded, Arduino/Teensyduino set up ... n ready to roll. Will activate my Teensy 4.0 and see what I can do over the weekend.

hmm ... I could have a look too. Can you pls reply with a link to the source code? (I will not be able to test and debug though ... I have a arduino derivative)

win? of COURSE win! Bit this violent jolt is scary sweet... pretty sure you want to reduce the lag ... and then control the hit as well! Like this its like a "eject" 😛 (closed loop to boost read out with a "target boost" table??? 😉)

nope ... not out of hand at all! Much appreciated!

samooooth! 🤪 looks like finally you hit the nail on the head with this combo for your application! (don't know what else you can throw at it if it does not give you the 850 hp) love the direct drive smoothness, seriously! (the belt drive is plagued with much more noise!)

what did u mean with "dumb references"?

On offroad trucks where people like to run e.g. some a led bar and fridge e.g. a "second thought" re alternator and battery system already is good practice! If they want to run a whinch as well then it is not only "good practice", but a dual battery system inevitable. For off road trucks the...

yeah ... I feel reminded to the "COVID mega PR campaigns" (not that COVID is fake ... its the handling and PRESS around it which is a big mess!) time for main stream media to learn some lessons ... if they don't up their game history (democratizing press) will make them obsolete!

yeaayy ... awesome!

yeah ... on my very short shortlist is a VESC 75/300 plus LMT 3080/6, 875KV, 2 pole babe

Looks like LMT motors with 6 connectors are wound in a nice (open!) way which actually allows you to configure the winding termination as you need. see here the explanation regarding 6 connector 3 phase motors: https://www.pumpsandsystems.com/motors/why-wye-why-delta The straps I am referring...

And then you have those: https://www.mgm-controllers.com/delta-straps And if you look at the MGM ESC ... a wire pair comes from the SAME solder tab!

yep ... I have seen those groved Powerdyne pulleys (for rebuilds) on ebay some time ago. The grooves supposed to help with the noise as well! (wheeeEEEEE) and yes ... the sensors on a emotor are more for the low rpm AND STARTUP sync! BUT ... even if you play with the throttle curve (to limit...
