[s-cars] Bosch Motorsport 044 Fuel Pump

[Trevor Frank]

I think it operates, but instantaneous fuel pressure drops a bit I think
even with the meager hp that I was pushing, pressure drop and fuel
lines/fuel pumps might be easily overlooked.  I suspect that I saw this
and kinda blamed my fuel pressure regulator, but it's a good one IMHO,
Javad has the same one.  In a severe case you could have a lean knock on
heavy acceleration especially if the fuel pump has been working hard for
a while and is heated up.  It might be missed as bad tuning?  I would
think that the efficiency of it would drop with temperature, since I
believe magnet's loose there effectiveness and gaps probably grow.  It
also warms up the fuel and I suspect could increase the inlet
temperature enough to effect detonation.  A descent energy/accumulator
might not be a bad idea either, like on a cis system.  Since Fluid is
"non compressible" one with a diaphragm/bellows and either a calibrated
spring for the operating fuel pressure or air pressure.  Just and empty
can and I suspect you are just hoping that the can flexes enough to help
absorb the loss of fuel.  Of course no answers but something to at least
think about.

Just out of curiosity... why pursue this?  It seems clear that the stock
pump is proven to deliver to nearly 450whp... why make things more
complex?  Your stock pump is either weak, or not getting the proper
voltage... or your FPR isn't performing correctly.
