Can I run a Walbro 190lph pump with no other fuel mods?

[98TsiAWD]

Here are my mods:

K&N FIPK
1g BOV
Brode Upper IC Pipe
MBC@15psi
Hacked Dump Tube
Sheetmetal Cold Air Box
Greddy Lower IC Pipe
Rewired Fuel Pump
Accel 8mm Blue Plug Wires
NGK BPR7ES Plugs
Dejon 2.5" Turbo Inlet Pipe.

Can I run the 190lph pump on this setup with no problems? I just dont want to buy the pump, injectors, and dsmlink and eprom all at once. I know I need some fuel control once I put injectors in, but with the stock 450's will I be just fine?

I'm running a Walbro 255 with no injectors, a-fpr, s-afc or logging software... of course, I'm running just a tad rich I just have't gotten around to putting in the s-afc and injectors that are sitting in my garage.

Yes you can. I ran a 255 also with no other fuel control and passed emissions.

i am gonan run a walbro 255HP fuel pump with no fuel controlls. is that gonna mess up my engine? Also while chaning the fuel filter i managed to break my fuel line under the filter anyone know of a way to fix it? or a kit ?

 

[Atari007]

what kind of gas milage do you guys get with the 255?

really not trying to bring up the dead, but that's my question as well...i have evo 16g, 1g bov, MBC and intake. i want to rewire and install a 190lph pump. am i able to do that without doing anything else? and if so, what can i boost at safely?

 

[Afroclipse]

Get a logger before trying to raise the boost, like my mother always says PREVENTION IS BETTER THAN CURE.

I've been running a rewired Walbro 190 for over a year now on the stock FPR. After reading over and over again about the downsides of fuel overrun and about getting poor gas mileage, I ordered an Aeromotive AFPR and gauge today. Many will tell you that you don't need it and I can attest to the fact that my car runs great as is, but I would rather be safe than sorry (and sorry is the word for my current gas mileage). I want to know for sure what my base fuel pressure is and I suspect my gas mileage may improve. Maybe not by much because I run my motor in the boost much of the time with a fast spooling Big28, but anything better will be appreciated.

You should be fine, that's what I did. I ran a rewired fuel pump only on my EVO3 until I got my DSMLink and injectors. There are other factors involved to safely raise boost than just fuel mods. As Afroclipse said, get a logger and raise boost accordingly. If I were to take a stab, I wouldn't go past 15-16 psi.

Fuel pump upgrades can be done with no fuel controller. If you're running 93 Octane, some say you can get away with 17-18psi. But I strongly suggest that you don't go over 16psi on that EVO3 without a logger.

Scroll down a bit to get a good idea of turbo psi/fuel requirments with that chart

Haha it is funny to read the first 3 posts from founder/wise man about fuel pumps.

 

[Siral3x]

yep, you definately run rich with a 255lph pump and no AFPR
I remember my 450ccs@18psi boost(on the 14b) where maxed out in 3rd gear at WOT in like NO TIME.
Without a logger I would have never known....I will never ever turn up the boost unless I got a way to logg the run.

 

[MelloEclipse]

so, walbro 190lph pump and a datalogger, eh?

 

[Siral3x]

yep, that's what I would do.

 

[Eastwood95]

Walboro 190 or EVO 8 (190lph and much cheaper) fuel pump, rewired, and datalogger/pocketlogger.

Hook up a FP gauge to that 190 after you put it in, and see how much overrun you are getting after the install. Just get an afpr.
