This seems like the answer to the dreams of all 1.7L owners: an electric turbo. Check out this clip:

In another video he takes the same car to the drag strip. Did so much better that he ordered another for twin turbos.

The issue will be fueling for a 4 cyl. If you had megasquirt or something similar you could easily setup this electric turbo with a throttle ramp and have a legitimate 40 WHP gain.

Anyone seen the YouTube video with the guy from Europe @ Sema supplying a complete kit with proven results,comes with 48V (?) power supply ,not sure what the price was.

Really stupid idea .
I mean 1st off is it a turbo or a supercharger.

And n/a air cooled engines are not boost friendly .
So reliablity will suffer

Nobody said it so I will....


You can't turbo a 914!

I'd find a better use for $2.5k and dyno time $. 2 hair dryers and $5k? No way. No telling the carnage the 'insta power' might induce to the drivetrain. Some cheap beater car from an auction? Who cares?

When mark h
Starts using these then ill be sold

Until then it just " shit from radio shack "
The hurt locker

They just posted a twin charged dyno test the other day. DAMN impressive.

They didn't expect it to do anything (first video) like the first 'electric turbo' they tried, but this one shocked them about how well it works.

Boost makes power no surprise.

You have to keep the car running and a over a certain amperage to charge the box, so it's obvious they're using some big ass capacitors in the box. BTW it's enough to be lethal so I wouldn't mess around with the box.
If you noticed power dropped when not in use, so the turbo is a restriction.
I doubt if D-jet could keep the AFR up to the boost so you would likely need an EFI system to adjust the timing and fuel maps to the boost.
The boost isn't earth shattering at 5 pounds, but that's about all a T4 can handle and have a chance at a reasonable lifespan.

So it's OK for the dragstrip, but it wouldn't fair to well on a track or everyday use. For my money I'd do one of McMarks 1.7 turbo systems before I'd plop down $2500 on this electric turbo. 1.7's can be had for cheap so if you don't mind wrenching whenever a engine pops this could be for you.

Most of my engine builds are NA and high CR, so I'd be looking to build a lower CR engine for turbo.The stock 914 engines are likely OK to go as most are 8.5:1 CR or lower.

Easy Run E85.

EG33 is 10.0:1 and will handle about 7 psi in stock form with E85, all day long not an issue.

On the 1.7 & E-85, and a bit of charge cooling, water or methane would help keep the unit from being a grenade and I would run it and see what happens, when you need more, just add it.

Also if you wanted to run this, then just add a bypass around the turbo, when you don't want to add extra grunt from the electric snail.

BTW @http://www.914world.com/bbs2/index.php?showuser=11572 technically a Turbo is a supercharger. Turbocharge just defines a subset of superchargers that are driven by exhaust gases, or other means beyond being mechanical.

In street vernacular a Supercharger is limited to anything that has a mechanical drive, and Turbo Chargers are exhaust driven. That is an electric Supercharger, and is similar in design to a Paxton, or other centrifugal supercharger.

In the true definition they are both part to the Supercharger family. Much like a beagle and a Great Dane are the same family, just developed into two completely different canines.
