all he did was swap the injectors and tune for them right? or did he change any other parts.

 

swapped them into the 60s harness and tune for them...u have a pm

 

I would be afraid of starving the last cylinder at least. Hope it works for him though. That would make it easier. I wouldn't trust it though.

Witt has an extra fuel pump. I was afraid of the pressure not going down properly at idle due to the large volume trying to be returned!

 

yea were working that out right now...everything is being monitered all the time

 

RETURN SYSTEM is the proper way to set up the fuel system for more than 300-350 whp. You are just risking your engine otherwise IMO.

 

lol like i said...i know..but im broke because of the stupid engine...

 

Yeah, but imaging having to build a new engine cause you go lean and fry it?! That is what I am saying. I have learned in the past that you have to finish the entire build properly or you will only have problems. Either with parts breaking or things just not running like they should.

 

i dunno i think it will be fine for now..so do ALOT of the knowledgable people on here...but deff gonna upgrade soon

 

I'm not saying it can't do it, I'm saying I wouldn't bet on it if it were mine!
I have never actually tested OEM flow/pressure maximums. So I can't honestly say it will reach a maximum safe flow of 200L/hr @ 58psi

I wish I knew cause I am trying to figure out how far I can stretch the OEM in tank pump!

My concern is that fact that when the system is set to maintain 58psi at the tank in the returnless setup and you are flowing 3X's the fuel in the system I would worry that the pressure would drop at the rail.

If you are monitoring it constantly and see no proplem then it should be OK.

 

thats why people like me and u are test dummys lol

 

Yep, blow up and waste $1000's to tell others what not to do!

 

i'm gonna have to pass on that one

 

With a compressor swap they won't without a supplemental pump.
No point in swapping if you are goin to leave the fuel pump stock.
Regulator has control of the rail. Fluid dynamics are much different than gas.
Pressure relief above 3 bar is much less due to the amount being relieved in my experience at that high of a pressure.

Results = truth Wait till I have solid proof in the next couple of weeks.

 

i will be patiently

 

I swaped to a return system so I can change the fuel pressure and keep the fuel in the fuel rail cooler. I had bad vapor lock last summer in 100*+ heat.

And if the flow becomes great enough the rail pressure will drop off. I suppose this would mostly be caused by a failure of the pump to keep up however.
I also had this problem when my fuel filter became clogged.

 

Either failure of the pump or a restriction of the fuel supply line would cause the problem you are describing.
