Lol. I would not recommend trying that. That's a quick way to have your friends call you stumpy. The first time you run one under power, you'll see what I mean. That said, when I was doing my testing, even mounted to the relatively heavy aluminum test bracket, it would easily fly off under...

I have two of these. The bearings they come with aren't the greatest, but so far no problems. Run it in for a bit, and if you're not happy, you can always drop in better bearings. Considering the price point, I didn't expect high end bearings.

On a 500 hp NA engine, it's equivalent to 1 psi boost "loss." So it's not actually noticeable on the street.

I would not put the unit in a hot engine bay directly; particularly over any exhaust components. The magnets in a brushless motor can start to demagnetize above 180* F. Low mounted in front is fine (mine is next to my radiator), pulling in air from the fender well, or you could mount it in the...

First of all, thanks to all of you for keeping this forum alive. I have been working 7 days a week to get "Alex Labs" up and running. The goal is a video studio with a dyno so I can continue with electric supercharger development and testing (among other things). It's been 3 years and one...

I initially had a water jacket cooling system on my setup, but found that it wasn't necessary with adequate airflow. Heck, even without adequate airflow, these things don't really run long enough to get much more than warm. As to why I push the P2 so hard (I get nothing from people buying...

If you're not in boost, then your stock maps aren't affected. I've been running my methanol setup to turn on and off with the electric supercharger. It does spike the AFR rich while the electric supercharger spools up; but it's so quick that it's not an issue - thick accel pump shot. I can...

Spec-wise, it looks better than the MAX4. However, it is significantly smaller and lighter than the MAX4. FWIW, I wasn't over-volting the ESC. They are rated for 12S; with each cell having a max voltage of 4.2 volts - which gives you 50.4 volts. The caps inside are rated for 63 volts. I...

I initially did a water jacket/pump cooling type setup. I found that the air movement of the car was more than enough to keep the motor cool. As long as you have some degree of airflow, you'll probably be ok. I do want to put a bunch of these in the back of an SUV or truck, in which case...

Lol. That thing's been around for a long time:

Oh I bet those cells weren't cheap. I've been looking at those motors as well; tbh the higher kv of the Castle motors is what keep me using them. Why only 36-38 volts? I think you'll find you'll need about 20s packs to run them at full power (voltage sag and all). Of course, this is...

Hi All - I know I've been under the radar for a while now - moving in to barndominium, unpacking stuff, still working on the building & property quite a bit. But I really needed to move forward with thing on the electric supercharger front. After all, the whole point of this move was to be...

Those should be very potent. My LTO cells are only 18 amp hr and have no issues putting out 678 amps running the sledgehammer. How many did you buy, and what motor/ESC/compressor will you be using?

That thing looks neat; I did mess around with VESC for a while and had problems with repeatability and high eRPM performance. How many poles does the motor have? The lower the better as far as VESC and high speed running is concerned.

The P2 is basically a Vortech Si trim.

Nice. Sorry I've not been focusing on this forum - the barndominium build has been all consuming. But we're nearing the end. Stainless may not be the best choice, since it does tend to warp a lot more than say mild steel, but I'm honestly just guessing. I do know that in my talks with...

Yes, I did. I ran dyno tests and track tests. Picked up good power: Here's the data deep dive: Here it is at the track:

I really need a set of gauge pins myself. A one piece shaft is probably the best idea - looking forward to seeing how your turns out.

That looks to be a small roots unit like the AMR500. It's highly inefficient and very limited in terms of hp output - just over 100hp max. I find it odd that they claim 600 amps at 12 volts and it can run off a car's existing electrical system, but there's no way that would happen. They're...

What GTHound said. Though 2 psi isn't much, 4 psi starts to become very noticeable - it's about the same as 5-6 psi of conventional turbo boost.
