if your going over 300bhp then buy the walbro but if not then the cupra pump is plenty and £40 is not a bad price

also if your going for high fuel pressure eg 5bar+ then the cupra pump will break

4 bar is overkill on most so 5 will be useless  :wink:

true 3bar is sound on a good map but then again I got around 210bhp with only 5bar fuel pressure and 18psi boost

standard fuel pressure is 3bar on 150 and 180bhp engines and 4bar on the 225bhp engines
but anything higher than 4bar will put a lot of pressure on the standard fuel pump and injectors and may lead to them failing

So would u say the cupra r pump will be to much 4 a stage 2 map ?
What injectors do u recommend 4 stage 2

Post by: davidgtrr34 on 11 January 2014, 21:49
your standard pump and injectors are good for 250bhp with no problems

if your going for a new pump then get the walbro its £75 on ebay. the oem pump new would be around £150-£200 I think. As for the cupra pump it might have a lot done and could break. If I was you I would keep using your original and if it gives up then upgrade. 104k on the original is not a lot.

Hi there buddy, Ive had a cupra r fuel pump fitted for well over 6 months now, I'm running 313bhp and 341lbt done by Mr Nic at R Tech and it runs like a dream  :grin: was getting fuel starvation on the standard pump !!!

Took me less than 10 minutes to fit, make sure you buy a new gasket seal for the pump don't use your old one mate and there dirt cheap to buy

Is this a joke??! This definitely made my day. I can always trust the forum to provide entertainment!

Seriously though just put the car back to standard.

Depends what engine code he has as to whether maf + injectors are suitable for 250bhp.... AGU will top out at 235bhp for both.

Look at the Sytec P3031 pump, capable of 7bar its a fit and forget pump and seems to be very very popular with those who love to tune at the minute.

Sure you need to have FPR psi value + the boost pressure for the pump to stand up...so in most cases....the fuel pump sees over 4bar?  Could be wrong on that tho.   Have a read into fuel pressure and boost.

Post by: rockmonkey69 on 16 January 2014, 05:18
Only he's talking about static fuel pressures, 3 bar being mentioned as "sound on a good map". He's running 5 bar static fuel pressure so in most cases the pump is sees over 6 bars? Could be wrong on that though. Have a read into the previous post.
