hey dude ,my a/f is around 11.8 to 12 at wot ,no leaks ...
geting a wide band is a gud idea and is on it way , but i think it has nothing to do wid my injecters maxing out ....
com on guyz help me out ....

 

Double PUMPER is all your gonna need 1200cc injectors + rail and double pumper and your set I dont think your injectors should be anywere near maxed out if so you might have a tuning issue or a nasty boost leak

 

did you up your static fuel pressure with your aeromotive fpr if not do so that might be your problem we had a car on the dyno have this same problem we thought he hook up the fuel pump wrong but his fuel pressure needed to be turned up some then his duty cycle was at like 70% and this is with 1000cc and a 37 r on like 34 psi hope this helps.

 

how do you know you're at 11.8-12.0 at WOT and in the same sentence you said "wide band is a good idea and on the way"

 

LOL

 

I mean damn, I have a carefully calibrated butt dyno for HP but I can't sniff air molecules and tell you the AFR

 

@ mellon ...btw i doo had a wide band for a day or 2 after the tune got finished which unfortunaly belong to the tuner not me and ive returnd him back now ...
so coming to the topic .plz tell wat cuf be the reason ,1 more thing ..i hvnt installed aeromotive fpr yet so is that gobe help me ...

@yasir ... bari hasi a rai hei ...koi nai akhir bakri ki maa kab tak khair manae gii lolzzzz

 

@haseeb: dost, geedar ki 100 saal ki zindagi sey sher ki 1 din ki zindagi behtar hai. buri baat, fracture ka bahana nahee kartay :P
and btw, you got all those mods in your car, yet you never bothered to get a wideband. sad.

 

I'll take a stab at this...

I dont think an extra inline fuel pump will do the trick...all it will do is up the fuel pressure, but the amount of fuel sent will remain the same.

By the looks of the Buschur double pumper, it pumps in parallel, which will allow more fuel flow at the same pressure (relatively). So i would say ditch the inline and get the double pumper.

This is based on LOOKING at the Buschur double pumper setup and i dont personally have a double pumper, but it makes sense that in order to get more flow, you add a pump in parallel.

 

I wonder what numbers my car would make at THAT dyno

 

go with the twin pumps,do you have a fuel pressure gauge? if you dont you should get one.

 

hey i doo have a fuel pressure ill check my exact pressures today and will post em ..
u tell wat is ur idc at full boost ...
do u think twin walbro in tank is different than 1 in tank and 1 inline ?
thanx

 

call Buschur and ask....there customer service is second to none.

 

there might be a difference...I can tell you that with the 35R @ 30psi on 93 octane a single walbro and 1000cc injectors are at 107% IDC but with the BR twin pump I'm back down to 85%

 

Yes, it is different. https://www.evolutionm.net/forums/sh...d.php?t=262346 You get about 30% more fuel at 2 bar with the twin walbro in tank than you do with the two pumps in series like you have now.
