It does and can tax it, they run off the same lpfp. but with modulation on both sides in can work. Or just have a real good low pressure feed.
Same as Andre now (unless he upsized since his last dyno), 5858 I was less.
I think derek means how is it not robbing too much fuel from the hpfp feed

I think it's sorta unnecessary to point out that yes, if you don't upgrade your lpfp with a 5th injector setup it can allow the HPFP to starve.
A fifth injector might share the fuel source but doesn't steal high pressure fuel from the main injectors, that was my comment.

Oh I thought yours were bigger. I think before the 5th injector he was only running 4x.6 DP's, and I'm not sure what the TB pipe nozzle was. I'm running .6's as well and flow a ton less air than you guys for sure.
And I think he meant the other way, but regardless like you said if you have a really good LPFP system it should take away at all from the HPFP.

Ive been in contact with LOBA for their hpfp for over a year and a half. everytime I ask, "we are still developing it" not much of an answer but I wouldnt hold my breath.

has anyone upgraded their fans?
Had a small temperature spike today and got me thinking. Ive done tons of mishimoto slim fans installs on other vehicles so why not the gti?! since the oem has a 4 wire connector and module what would be the best way to do this? pop oem fan off, take motor out, keep module in place, splice in new fan power and ground, enjoy?
just a thought for now and if it works eveyone could benefit from it since:
1) it shouldnt be too hard
2) the mishimoto slims are relatively cheap when compared to replacing oem.

temp spikes aren't bad. fans would only be needed if you can't bring temps back down. my temps go up to 220 sometimes before they come back down, but they always come back down.
ecs has sizes listed for each of the fans in the shroud. but it's a tight fit as is, is the mishimoto version that much thinner/efficient?

Yea the mishimoto would be 14" for the latger and 12" for the smaller. what makes them even better is they are not exposed so (like ive encountered once without knowing) you wont have to risk the throttle body pipe getting sliced open by the fan.
and yea way more output from these. just did a set on my buddys fox body mustang. used to sit a little over 190 on the gauge at idle and now hangs out around 175/180 at idle.

Only reason I'd want to change the fans is for the tighter fitment, expecially with the drop in intercoolers pushing shit closer, ac lines are close etc. Small fan is the module however.

Jesus, do you have an angle grinder for a fan or something, lol.

RIGHT?! i had no idea! i was getting throttle cuts and codes for MAP sensor that had me going crazy! obviously coulndt see it and when i finally did a boost leak test sure enough thats what i found! all fixed now but definitely need to swap this out soon
Im thinking im going to go ahead and order the mishimoto fan and be the guinea pig on this. I did however see a puddle of coolant under the car this morning and looks like its either ANOTHER water pump or the feed hose for the radiator (looks to be coming from the clamp). Going to try the hose first while i wait for the fan.

That's just poor fitment. I've got an APR intercooler and a TyrolSport radiator and mine clears my Neuspeed throttle pipe. Not a mark on it. Maybe your fan is jacked up and out of balance and spins wonky when it goes high speed.
So confused... What the heck pump is that??
