Effectiveness of Fuel Pump Voltage Booster (Boost-A-Pump)

[SM105K]

Fair enough

Feels like AZFT days.....good times.

I've said my peace about the fuel line. If you all feel dropping bookoo bucks on pumps and boosters is super important but some pocket change to reduce frictional losses and therefore the demand on that pump is stupid, then more power to you all!

Yes more power to me....you are right.

Finally, write-up is done...check out the build thread...hate having to break up these write-ups, but the site only allows 20 images and 9900 (including spaces) characters per post...

So wait, this was all done to fix rail pressure "falling off" to 2900 psi?! Just to land at a tune with 2500 psi desired anyway?

Yeah, something like that...

It's very difficult to compare apples to apples with this. All the datalogs were done on widely different time intervals and there are some variables that are different, yes.

So to say my graphs are an oversimplification would be stating fact. However, some of that "difference" you are talking about is the fact that the first 2 runs was targeting 20psi of boost, while this latest one only peaked at 17psi. We turned the boost down for tuning for other reasons while we dial it it.

But I'm more concerned with the flatness and consistency of the curve versus the dips that I was seeing before, and that part seems to be holding up. The high pressure side is keeping with the desired value. So am I pleased? Yes. Is this a perfect solution? No.
