...and the AFR goes lean because fuel pressure has dropped. And then detonation sets in.

What's the worst that could happen?

 

Any inductive load I've ever seen draws LESS current the higher voltage you feed it. Same should be true of this pump, you double the voltage and the current should pull half. Power is power. All regulated DC-DC converters work this way. Just did this in the lab the other day.

 

Current pull from source will not reduce though. You cannot magic work/power from nothing.

 

I agree with you, power in equals power out of a DC to DC. The battery will feed the DC to DC with 12V @ let's say 15 amps....but the DC to DC will feed the pump with 24v and something like 7.5A depending on efficiency.

 

What does the BAP increase the voltage to?
24 seems rather high.

 

I just used that cause it was mentioned earlier in the thread. I though most good BAPs were adjustable and went up to like 18vdc.

 

90% of posts in this thread are incorrect.

P(power/watts)=I(current)V(voltage)
Work is power over time so they cannot be used synonymously. So in static systems you can double the current and half the voltage or vice versa and get the same power. This is why they step up voltage so high on transmission lines, so there is less current and hence less loss in the lines, but you still get the same power.
Dnspider electric pumps in a fluid are more complicated than an ideal inductive load. They will draw more current due to the increased torque needed to pump fuel at an increased speed that the voltage increase creates.
Boost a pumps do 18 or 21v from what Ive seen.
The argument about going lean if it fails is valid, dunno how robust some of these converters are, but there is always a chance of failure for any part, propper monitoring is key.

 

I can tell you that an AEM380 will fail if fed higher than 18V. Found out the hard way.

 

You can buy various units, some adjustable some fixed. I think max is usually around 20/22v though. Not sure I've seen 24v. But yea, I think 18v would be the more common.

 

its funny to read though.

 

90% of stats are untrue

 

Because 86% are made up on the spot.
