Robzki Posted June 15, 2012 Share Posted June 15, 2012 Why does it say that this much fuel flow is not meant for under 400hp? I thought that these still didn't flow as well as stock in real world conditions. Quote Link to comment Share on other sites More sharing options...
mellonman Posted June 15, 2012 Author Share Posted June 15, 2012 i think you got your wires crossed, they say the 255 is not suitable for more the 400hp but this would be car dependant so peoples first veiws are there are good Quote Link to comment Share on other sites More sharing options...
Robzki Posted June 15, 2012 Share Posted June 15, 2012 "This pump is a great solution for high fuel requirement turbocharged cars >500hp and anyone looking to make big power and run high boost with a simple fuel system where the 255 won't suffice. This much fuel flow is not meant for use on engines Which wires did I cross? Quote Link to comment Share on other sites More sharing options...
mellonman Posted June 15, 2012 Author Share Posted June 15, 2012 maybe i have mine crossed then, what ever the case it flows more fuel then the 255 which is what i need Quote Link to comment Share on other sites More sharing options...
Robzki Posted June 15, 2012 Share Posted June 15, 2012 , If my 255 failed I'd definitely go for one of these, not just for the flow but also for the quieter pump design. Quote Link to comment Share on other sites More sharing options...

I thought that these still didn't flow as well as stock in real world conditions. It may heat the fuel due to encountering flow restrictions in a system adequate for 400bhp?

Noz Posted June 15, 2012 Share Posted June 15, 2012 It may heat the fuel due to encountering flow restrictions in a system adequate for 400bhp? Maybe it's also to do with the frequency of the fuel delivery. If the flow is reduced the frequency may cause issues with fuel delivery from the injectors (wild guess) Quote Link to comment Share on other sites More sharing options...

Nodalmighty Posted June 15, 2012 Share Posted June 15, 2012 So when your idling or in slow traffic not making 400+bhp is the pump then no longer suitable for your set up? Lyndon. Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted June 15, 2012 Share Posted June 15, 2012 Fear tactics Rob. It's the only way to keep these free thinkers down. I could've said Cork if I'd wanted him to take his own life right there on the spot! Quote Link to comment Share on other sites More sharing options...
Robzki Posted June 15, 2012 Share Posted June 15, 2012 So when your idling or in slow traffic not making 400+bhp is the pump then no longer suitable for your set up? Lyndon. This was my thinking. Quote Link to comment Share on other sites More sharing options...

Lyndon. guys im sure that they have one of the the wrong way "This pump is a great solution for high fuel requirement turbocharged cars GREATER TAN 500hp and anyone looking to make big power and run high boost with a simple fuel system where the 255 won't suffice,This much fuel flow is not meant for use on engines GREATER THAN 400hp." i think its ment to read like that Quote Link to comment Share on other sites More sharing options...
Noz Posted June 15, 2012 Share Posted June 15, 2012 So was mine, but yours sounds much more convincing! Damn you Noz, damn you to Cornwall! Cornwall, that was a bit below the belt I was purely guessing, and to be fair, I think I should write childrens stories as it was a load of tosh being logical about it considering flow at traffic won't be pushing 400bhp! Back to bed I go. Quote Link to comment Share on other sites More sharing options...

So to clarify its good for cars over 500hp but not good for cars over 400hp. I assume from this that its all good under 400hp and over 500hp, but can't be used on anything 400-500hp?

mellonman Posted July 2, 2012 Author Share Posted July 2, 2012 no the 255 is no good over 400. that why the 400 if for greater then 500, but forget it i got one anyway i will let everyone know how i got on just trying to find out if i need to do a fuel ecu mod to run it Quote Link to comment Share on other sites More sharing options...
mellonman Posted July 4, 2012 Author Share Posted July 4, 2012 okay just fitted this pump my fuel pump ecu was not up to powering the pump so had to do a 12v mod to get it to run, but other people have had it work straight away they might have a uk spec yet to find out http://www.mkivsupra.net/vbb/attachment.php?attachmentid=154220&d=1341391583 Quote Link to comment Share on other sites More sharing options...
