- In this chapter of the electric turbo camaro project, all aspects of the installation are 100% completed including mechanical, high power electrical, electronics and programming. The programming is perfectly debugged yet but everything works at a baseline level. Here you'll see me switch everything on with the car running and activate the supercharger via the dedicated computer!
Things get real in Part 5, the conclusion! : • Electric Turbo Camaro ...
Go here to begin the saga from the beginning:

This is EPIC!
Damn rights! :D
Good afternoon Chris, been watching you progress with your car and electric turbo, have you stop progressing or are yoy going to post updates
Kind regards
Michael
Hey Michael! Ehhhhh.... the short answer is yes, I'm going to finish this and post another update video. The longer answer is I have so many things on the go right now, not all of them pleasant, that I haven't been able to get back to this in a timely manner. But it will get done. Last update is that the motor needed to be re-wound in order to spin fast enough to produce boost so now I have to reconnect it to the car and start carefully calibrating my boost curve so that I don't blow myself to kingdom come. This isn't an obstacle per se. It just takes many uninterrupted blocks of free time which I haven't had yet this season. Once I get to it, progress will occur quickly, since everything works in the technical sense, so this is just tuning and safety I have to get around to.
@@ChrisCamaro good afternoon Chris,thank you for taking the time to reply me and you explain, I have a Holden Caprice WN 6l and would love to try this,my problem is I Live in Launceston Tasmania Australia and hard to acquire parst and info,keep up the good work,
Thank you
Michael
Wholly Shit!
Wait so what happened?? It never got finished? Is there a part 5 coming or was the project abandoned or what? I was talking to the torqueamp dude about putting dual torqueamps on my LS3 to get the needed boost I just came across this I didn't even know if someone had done it yet or not. He seems to think with twin torque amps I wouldn't need a blowoff valve. I was asking what his plan was to cool the air though and he didn't have anything planned, the nitrous is the perfect solution if you can get it to just inject it as needed to keep the intake air temp where you want it to fully benefit from the boost.
I'm not a huge fan of torquamp. At least when I first discovered the brand and listened to some of their advertising material and tech talks, they sounded like they were completely full of shit. If I recall correctly they had some dyno curve from a torqueamp attached to a 4-banger and then said it would do the same thing on a V6 or V8, no difference. Lost all credibility when I heard that, especially given the flow numbers they were disclosing for their blower unit. To answer your first question, the project isn't dead but to be honest I simply haven't had the time. That may sound horribly lame but I really am totally burnt out at the moment and have driven my Camaro a grand total of maybe 4 times this year. I am truly sorry for making anyone here wait for an update. I believe it may be possible for me to do some testing in the coming weeks however. I can't make any promises but I'm going to try very hard to get something done this season. There isn't much left to do really. I just have to go for a drive and test the thing. The problem is, with something I programmed myself and >250 amps flowing through an under-sized controller, I really really don't want to blow anything up or kill myself so I need a contiguous block of time with nothing to distract me so I can check and double check everything and then test it. Once I pass that milestone I'll have something worth reporting. Just hang in there a bit longer.
Any updates 🔥🔥🔥
So last year I reached an impasse with testing where, I was able to get the motor to perform roughly how I wanted it to on the road (ie. It would trigger and run given a certain range of inputs like throttle, RPM etc) but I was getting no boost. The problem was that the motor wasn't wound correctly (Wye vs Delta). Essentially I was getting plenty of torque but no speed. I had the motor re-wound but by the time I got it back I didn't have any more time in the season to work on it. The next step is to hook everything back up all over again and try it again. I have some trivial work to do regarding fasteners and connections since the motor was re-worked and then I have to determine the new PWM profile for this new winding configuration (since it will run a lot faster than anticipated now). Once I dial that in and get a successful road test I'll have something tangible to report. I'm rather busy these days so it might be a little while but I have a clear path forward now. In theory there's nothing stopping this thing from working correctly so let's see if I can reach this next critical milestone by the end of this summer!
If you don't mind what is the model of your. Brushless motor and where can it be purchased?
The motor/supercharger isn't retail. It has no "model number" per se. It's a custom build from Thomas Knight of Thomas Knight Superchargers.
@@ChrisCamaro thank you for the info. Guess my next question is about your battery pack. How long does it last under full load and don't remember hearing, but more than likely I just missed it, is your battery pack 48 volts? As the 2 units your used is 60c (120c burst) 22.2V. I take it your running them in Series 48v?
As of right the battery setup is all I honestly have to work out. As i have already order a compressor housing / blower and Motor. Know what controller i will be ordering and by the way your custom ESC and diagnostic setup is next level. Just have figure out what battery setup and charging i want to use.
@@mark120371 I'm using 2 x Turnigy 7S batteries in PARALLEL. The nominal voltage is 25.9 but fully charged it's around 28 or so. I haven't done enough road testing to totally drain the batteries and measure how long they lasted but I would estimate somewhere between 60s and 100s of total runtime. The controller I'm using can't really take more than 30V so a 7S is the highest I can go. However this all depends on the motor and controller you're using.
@ChrisCamaro You're gonna need more voltage once its all said and done though right? You think the prismatic cells will end up giving you the power you need to get the boost you want? When I was thinking about doing the dual torqueamps I was going to use prysmatics just because I already have everything on hand to build the needed 48V power storage I would just need a BMS, but I think the right way to do it is with headway. For the same amount of weight you'd get a decent increase in capacity and way higher discharge for when you need it without seeing that voltage drop. You could upgrade the controller and run at 48V without any voltage drop at all with the headway assuming you can get enough capacity I honestly have no clue I haven't attempted any weight calculations to determine how much it would actually weigh to be able to use the boost as much as you want within reason without having to worry about draining the power storage and dropping the voltage and performance way down and not being able to catch back up. I dont have the funds to get into it now but I was going to build my own power storage because what he's providing with the torquamp kits is nowhere near the capacity I personally would want to have to fully utilize it and not be driving around trying to charge the batteries for an hour for a few seconds or a minute of boost. My plan was to get enough power storage in the trunk that it could feed both torqueamps and provide as much boost as I want without having to let off and let the batteries recharge, and then of course I would have to plug it in at night and replenish the depleted power from throughout the day depending on how much driving I did. I hate the idea of being limited and only being able to use it briefly and then have to wait who knows how long for the 14.4V alternator to recharge the 48V power cells.
Unless you put a massive alternator in I don't see it working very well with the power storage he’s including with those kits. I've looked into it I know you can get some crazy 350amp alternators for $1500 or wte it was and I'm sure that would go a long way to keeping the cells charged, but how much extra horspower would an alternator like that eat up? Unless they're just way higher quality and way more efficient, I would assume those really high output alternators must take significantly more HP to spin right? And even with an alternator upgrade it still wouldn't cut it I don't think unless you have a decent capacity and the right wiring and high discharge cells to get the power there when it calls for it. That little 8 gauge wire or wte those kits being sold come with isn't going to cut it I dont think. I know at 48V even super high current comparatively can pass through way smaller wire than with 12V but still I don't see 8 Guage wire or wte little wire is being used being able to get that amount of current all the way from the trunk to the compressors under the hood especially as things get hot. My 2SS 1LE with the big ass alternator they come with doesn't keep up with stop and go driving with all the audio equipment and radar/laser blocking systems and everything else on top of all the extra stock electronics with the 2SS to begin with.
Even after running massive 2/0 tinned copper power and ground cables everywhere in addition to the stock wiring, I was finally getting power to everything efficiently but it was draining the stock battery even with the best AGM replacement I could get it would drain it over time. I had to invest in a big ass lithium battery just for the daily driving with what’s installed to keep up once i upgraded all the wiring. It doesn't drain it right away but over time it will slowly lose voltage with normal daily driving unless I took it down the highway for hours to recharge it. If not I have to plug it in every couple weeks or so just to keep the voltage from creeping down. I guess I could probably place a little solar panal somewhere in the back where it could grab enough sun to make up for the super gradual voltage loss or I could upgade the alternator but its really not an issue now with the lithium battery.
I can't imagine trying to rely on the alternator to recharge a small limited 48v power storage unit like the one that comes with the torqueamp though on top of everything else. I would never even get to use the boost. If i can get dense enough power with headway to not have to worry about it all day I would gladly plug it in to replenish it at night vs trying to somehow get the power from the charging system to recharge the power storage over and over every time the electric superchargers depleted it throughout the day while driving it. Def would ruin it for me.
