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:

How are the Ukrainians supposed to hold free and fair elections with international observers when 20% of their territory is illegally occupied by genocidal, murdering ruzzian psychopaths intent on killing all Ukrainians, destroying Ukrainian language and culture and lobbing massive cruise and...

You've been told lies, and unfortunately chosen to believe them - tucker carlson isn't a reliable source (as even the courts have adjudicated him as not a journalist, but "entertainment"), and putin is a well-known liar. Let me present you with the truth, and I will encourage you to do your own...

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.

Boost at very low rpm is a bad idea. It creates a tremendous amount of cylinder pressure and can cause severe engine damage - it makes your tuning window small, can cause uncontrollable detonation, blow head gaskets, beat up rod bearings, etc. If you need more low end grunt, the best bet is to...

I tested several smaller batteries in a video here: I didn't test that battery in particular but it'll give you an idea of the range you could be looking at.

There really is no standard for C rate. In other words you don't know what the voltage sag is going to be under that load. I really don't think any battery that small can provide the kind of current levels we're looking for. Generally speaking within the same chemistry, The greater the amp...

That would be a false positive. I had Godaddy (the host) take over the SSL stuff. Should be good to go.

Hi Mateen - how do you plan on connecting the 18650 cells? I have bought 180 a123 systems lithium iron phosphate cells but ended up not using them because I couldn't come up with a way to connect them all that could reliably carry the current

Welcome!

I don't think it'll make enough boost to make intercooling or injection worthwhile. On the other hand, I've always had a thing for Jaguar sedans - particularly the round eyes. One day...
