Nobody thought of a gas powered one? duh<BR>A long pull cord and some duct tape...

I applied my little bit of gray matter that is still functioning to this thing and, you know if you fitted an alternator isolator switch that cut the connection from the alternator to the battery the booster would run of the stored power in the battery and not from the alternator..<BR>Perhaps a double pole relay instead of the single one on the execrator peddle.. And when you are not flooring it the battery would get recharged...Umm maybe...although I don't know how the CPU would cope with the spike in volts...still you could always fit an arrested...and you may need a bigger battery…<BR>Even the alternator isolator makes a difference to the power on load (I've got it on another car that I’ve got)

With a larger resourvor of avaible power, it whould be possible to make an eletrically driven compressor that could respond to an increase in rpm (because its not being maxed out all the time......), but its all just specualtion, so it take it at that, lol :p

Hmm....well I live on the real world, where people don't increase their electrical systems to 42v, so I'm going to go ahead and say that converting mechanical energy to electrical energy to mechanical energy is a bad idea. :)

Actually this ERAM thingy does run off the battery and not the alternator if you believe their advertisement.<BR>However, the only person with experience with this thing said it doesn't work and that's good enough for me.

hey how about a gas powered leaf blower!! couldn't you just imagine some guy pulling up to you at a stop light, and he is pull starting a leaf blower from inside... oh boy ive got to get to bed.

The idea of having an electric system forcing air into the intake is very good. <P>- I hear say the energy taken on the alternator eleminate the effect. <BR>THAT IS NOT TRUE, because u take some energy <BR>from the alternator to compress the intake gasses, hawever that allows to burn more fuel<BR>which will generate much more energy than what is used to compress the air. it is exactelly the same as a turbo or a gas turbine.<P>- On the other hand the system here looks a bit crappy and dose not perform well. you need more than 15-20kpa (2-3 psi) to have a significant effect. As well an other difficulty is that the flow sensor on the mx is volume flow, by increasing pressure the volume flow will not vary because you compress the air but the mass flow will increase. u need to find a way to let the ecu know that it has to put more fuel.<P>well i hope these explainations will make things a bit clearer for the electric compressors.<P>cherrio,<P>Buckrodgers. :cool:

Well the Fiat group has been developing an electric turbo and I think GM has been working on it a bit.<P>Hawever this is serious project not like <BR>the little fan discussed here. The point i wanted to raise is that the idea is good<BR>but it needs proper realisation by engineers. <P>an electric turbo could allow to get rid of the traditional lag and provide some enormous torque at low revs where the exhaust gas flow would not be suficient to produce the desired pressure rise.<P>And don't say something is BS before you understand it. <P>here the concept is good but the realisation up to now is BS.<P>cheerio<P>Buckrodgers
