as it says in the title....how much power will a walbro 255lph support assuming fpr and uprated injectors etc

Thanks

I was running 1.5bar on a 2.6 with no problems. Using Sard 800cc injectors..

Approx 1725kg/hr of air at 10:1 AFR with a 10% safety margin. 1725kg/hr of air is 530 - 580PS......

10:1,i mean who would do this in a Skyline

 

[ExScoobyT]

Maybe no one, but it serves as an easy calculation point and builds in some more safety.........

Where are the graphs that show what the flow rate is at between 4 to 6 bar fuel pressure?

Without those graphs compared to the boost pressure you are using, it's pure guesswork what power any fuel pump will support.

The graphs I have seen for the Walbro do support [email protected] [email protected]

Flow rate did drop quickly with lower voltage, but held up with increasing pressure until approx 5bar........

I've seen heaps of these walbro fuel pumps on ebay for sale - are they legitimate items as they seem fairly cheap at £90 ...I'm looking to upgrade mine very soon so would these ones off ebay be worth getting? I'm not looking to run any more than 350-400bhp really (thats including n20 at 50bhp)

I bought mine for £80 off ebay and its fine.

i need a pump that will supply enough fuel for 600 ish horses. Also what kind of pressure would be recomended for the regulator...

Am using 2x of those pumps they are very good

one walbro is good for abour 450hp with no loss of fuel pressure at high power. If you're after 600hp, I would go with a couple of pumps, either walbro or Bosch. There are some good bosch pumps that cost less than a walbro.
