LMFAO!!!

Sort of relevant to this thread .
Ford in Europe are developing a high power version of the
three cylinder, 1 litre ECOBoost engine which has sequential turbochargers.
The first one is spun up by an electric
motor to give boost at low revs and cut lag then once revs
rise the second turbo feeds in.
This light and tiny engine produces 177 hp from 1 litre.
Isn't technology wonderful.
Also this engine is going to be available in family cars
in the UK very soon so supercharging using electric motors
is already quite mainstream.

valeo are the leading electric supercharger manufacturers in europe/uk they've tested units in ford/nissan/renault and vw-audi. most of the next gen cars plan to use it and its use is being written in to grp a,n and national class m sport development specs apparently. saw a proposed electric anti lag system set up recently looked nice but car wasn't running so chance to see it in action. they would make good leaf blowers.

thats pretty funny. problem is, that design, a direct copy of what the eRAM looked like, but with a much lower powered electric motor. (and some inefficient flan blades) when you get an electric motor that can generate near 1psi static pressure (ie, near stalled) that pressure curve with its flow potenital (volume of air , or CFM), and the losses in the air box, due to restriction ( i.e. pressure drop), we can see a net gain of about 1psi in the airbox itself. near 10hp gains in many cars in the 200rwhp range. the eRAM is up to about 1000watts now. the higher power DC brushless version also can use a 24 volt supply and take near 2000watts. doing some dyno work now on a mustang to see if it can add some pressure to the intake at redline.

The viideo was pretty funny though, and too bad they didnt have an actual eRAM to test.

Spinning up a turbo to reduce lag is quiet different than an actual electric supercharge.

Wait a minute.

The 928 turbo guru's tell me there is no more turbo lag.

Someone needs to get Ford in this forum so they can learn the secrets.

This is a 1L engine.
