There are at least three separate threads on this forum discussing electric turbos and e-superchargers with a combined view count pushing 20k, which tells me there's real interest but the info is scattered. Figured it's worth one current thread since the technology has moved a bit in the past couple of years.
Quick summary of where things stand as I understand it.
What works:
Low-pressure e-compressors used as anti-lag or spool assist on an existing turbo setup. You're not making power with the e-unit -- you're using it to keep intake pressure up at low RPM while the main turbo catches up. A few builds here have done this successfully.
Standalone e-supercharger at low boost (3 to 5psi) for a mild bump on an otherwise N/A motor. The power draw is substantial and you need a secondary battery or upgraded alternator, but it's been done.
What doesn't work:
Replacing a conventional turbo entirely with an e-unit on a 1UZ. The power-to-airflow math doesn't work at 12V. You'd need a 48V system minimum to move meaningful air at usable boost pressures.
The cheap Amazon/eBay units marketed as electric turbos. They're intake fans that generate negligible pressure rise. Plenty of dyno evidence on this.
Anyone running an actual working setup right now, post it here. Specifically interested in what unit you're running, power draw, voltage system, supporting mods, and before/after numbers if you have them.
