I'm confused

if a car without the product advertised suffers from fuel surge, then surely a car with the product fitted will suffer with its fuel supply to the swirl pot caused by surge.

Is some kind of baffling of the tank used as well or is the capacity of the swirl pot enough to supply the engine with constant fueling in times of driving where surge is an issue.

thanks

Don't ask me, I only update their website

But I do know that the swirl pot has a fair capacity, so it is going to last you even the really long high G corners, like those found at Snetterton etc.

I was in the car at Donington, at full throttle, with the fuel gauge needle actually below 'E' and it didn't miss a beat.

Don't know any really technical details, but I do know it works.

Cheers

Jay, thats because it's the same size as your petrol tank!!!

Regarding the High Pressure pump kit, the blurb accompanying the product states:

<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:<HR>The standard pump in good working order can barely supply enough fuel for an unmodified engine. If the boost has been increased over standard this makes the problem worse causing leaning off at high rpms. Powerstation have sourced a high flow, high pressure, easy to change, direct replacement fuel pump that solves this problem.<HR></BLOCKQUOTE>

Do Powerstation believe that the leaning out and detonation that can occur if the boost is increased without an ECU remap can be avoided by using a HP fuel pump?

Also does this imply that if an ECU remap is performed the standard fuel pump is inadequate?

Andrew...

 

Hi guys,

Its not a swirl pot.. its a surge tank, there is a difference

But yeah.. the principle is that it stores enough fuel to outlast the fuel starvation problem on a high G corner.

My tank has enough fuel to last approx 40 seconds... more than enough

AndrewC, the injectors run out of capacity before the fuel pump gets near to it. And no, changing ecu does not involve the necessity to change the fuel pump unless a big (and I mean big) turbo is fitted, ran my STi 2 wagon on Motec with the TD05H turbo (flows large amounts of air) with induction kit, downpipe and Hper exhaust and never exceeded 83% duty ... I just uprated my injectors. Even ran standard fuel pressure. Injector capacity is the initial limiting factor. Of course an uprated fuel pump won't hurt anything, just pumps the fuel around the loop faster. Pressure drop across the injectors and injector orifice area are what determines the injector flow capacilty.
