electric supercharger response

It sounds like a cool idea, but it is quite easy for the Bosch alternator=

in an E30 to drain over 5 hp from the engine when it is
under high load.  Therefore, chances are good that the electric
supercharger could actually cost power.

Now, if it could create 40 hp or more, that would be a fantastic upgrade.=
 =

There are not many drivers that could notice a 5 hp
increase unless it was on a Honda 5 h<

>>>>>>>>>>

our tests on the dyno show 4 hp on a honda 4 banger and 9 hp on a porshce=

928 2 valve race car. These figures are on the ground!!!!  and e30 can pu=
t
160 stock to 200 to the ground , and this should add the 3% no mater what=

you have done .  We have already done the tests.

the altenator doesnt work that way, I dont think.   when you start your c=
ar
you drain 80  or more amps for a couple of seconds. this is a couple of h=
p.
the altenator then takes a few minutes to recharge what was taken from
thebattery.  thats why you have a battery, otherwise you would have a
magnito.     anyway, the fan only works for about 7 to 10 seconds and is
released  and so on.
on the race track, no problem.  it is on for 40 seconds on a 2 minute lap=

at laguna seca.  On the street is on for an order of magnitude less.  =


So , it works, and it will be tested further on midsize engines for
comparison.
40 hp would require 1.5 to 2 psi of boost , that would be  (if it could b=
e
done by an axial blower , which it cant)  6 hp to move 300 cfm at 1.5to 2=

psi .   this is just basic physics.     6 hp would be at 12 volts , well
lets just say , 2 or 300 amps.   (after you factor all the inefficiencies=

in)

any comments.   It works and it is nice to have the extra 10 hp on the
track because over time , it helps.
besides, how many people on this list have spent 100 bucks on  plug wires=
,
chips, air cleaners, cool air tubes , that at best provide less hp and
maybe  none.    The electric ram air is a mass flow device and does work
for obvios reasons.
