Thinking back to the days of the first 'tworbo' or twin charged mini, I've been watching for a couple of years the development of electric turbos that don't need plumbing into the exhaust systems to give you an increase in boost. The cheap ones seems mostly like gimmicky crap, but a company called Torqamp now makes a fully integrated system including the battery pack and controller that made an additional 40hp and 5 or 6 psi on a stock Chevy Cobalt that made around 115hp before. They did before/after dyno pulls, so you know exactly the hp it made on that car. The battery pack recharges during normal driving, and when engaged, it can run the turbo for 4 minutes at full boost. Not cheap at 2500 bucks, but if it made 40 hp on a car that baselined at 115, what might it do on one that is closer to 200?

Thoughts?

Idiots.

As for the Whammodyne 9000 here, trying to understand the purpose, other than "muh latest dyno numbers are way sick, bro." In a real turbocharger a portion of the car's waste energy is recovered to run the air pump that provides the boost that leads to greater power and torque, and also greater efficiency. With this set up, you're pulling power indirectly from the motor's flywheel, first converting it to electrical energy via the battery and alternator, before ultimately running the spool. In that way, it's almost more like supercharging, except now it comes with electrical losses and added weight to the car. Our cars already have a supercharger which seems to work pretty well for most people's applications, and there's no efficiency loss from an electrical conversion; the power comes right from the crank. Also no short term / long term damage on the motor from over boosting it (and you just know Beavis and Butthead here are going to run it at max, all the time). Finally where would you put it in an R53?

And $2500 is a lot for obvious gimmicky crap that will shorten the engine's life "way cool kit bro" Harrumph!

 

Cleatus I wont dare invoke his real name is a moron and hope he looses his speed facotry that being said the new high end oiless sealed turbos will be something.

 

Yep, he's a dolt for sure, but my primary interest in that video is before and after dyno runs (WAY to often in all sorts of engine mod videos, not done, or only an after is done) which do show quite substantial evidence-based gains in HP and torque.

As for where it would go - I'd imagine you would have to strip out the airbox, plumb it in there and figure out some kind of re-located K&N filter. Not having to plumb this in means a huge exhaust manifold won't be required taking up space either. It's an interesting idea in any case for short spurts (several minutes only) of added boost.

 

The way I figure it, the weight of the power pack needed to run the thing at high enough current to do enough good … should jsut about negate any true benefit. On an r53 I see 0 benefit. It’s an indirect t driven centrifugal supercharger vs a direct driven rootes.

 

The battery life really limits the applications. And when the battery is down, you're just hauling around extra weight.
