sorry double post..evom is acting up.

 

Found it! very cool. thank you.

So the effect of this, all said and done is constant higher voltage to the pump, which will flow more fuel at higher rpm's/boost pressures, correct?

I thought kevin said earlier that this should handle any pressures the stock turbo can put out. So, what exactly does this equal?

Thanks again (slowly learning) and trying to add to the OP question!

 

At 43psi, 12.5volts and 10.8amperes the stock VIII pump flows 160lt/hr. At the same time, applying 14volts and 12.1amperes the stock VIII pump flows 202lt/hr at the same fuel pressure.

So as you can see flow rate with higher voltages/amperes allow for higher fuel delivery given the stock injectors' IDC doesnt exceed 100%, personally I wouldn't pass 80-90% to be safe.

 

Doing a quick search with "rewire" and my user name, I found some old threads where I went into some more detail.

I've run injectors at 100% for years and seen no problems, but everyone has their own personal comfort level.

 

If that is so, then the same concept must apply to the walbro 255 hp pump. Hp capability of that single pump would be sick!!!!

 

On pumps 255lph and up, I would not recomend NOT rewiring it. Pulling the ~20 amps or so it does through that tiny stock wire makes me nervous. It obviously works, but it makes me nervous. The difference in capacity between 12 volts and 14 volts is significant too. You might as well spend the 10-20 bucks and the most out of the pump.
