Just 2 questions...

What does a fuel pump voltage booster do?

When is when needed?

 

They increases voltage to the fuel pump, and therefore fuel flow.
Some switch to a higher voltage at a given TPS voltage of boost PSI, while others (such as the one I made https://www.camaroz28.com/forums/sho...d.php?t=810985) ramp voltage up linearly with boost.

They're used as a much simpler alternative to adding another pump when you're pump is maxed out.

 

I see...so is it only needed for superchargers or turbos?

 

No, any time your pump cannot deliver the fuel flow required, increase it's voltage and it pumps more fuel.

 

I have a 383 stroker in a 94Z...it has a walbro 255 fuel pump in it. Would one be needed?

 

Very unlikely. a walbro gss340 will support over 550hp

 

Thanks for the info...

Awesome thread, by the way. Nice work.
