Im at the Fuel stage of my project. Its a 1st gen w/ an s4 13bt. It has a 15gal Fuel cell mounted along w/ -6 an lines and a MSD Pump. Right now the car has a Stock turbo, but i plan to atleast get a BNR Upgrade. Currently it has 550 Primarys and 680 Secondaries. Would it be worth the extra $$$ to use a Parallel fuel set up? If it makes any difference at all, i have the Microtech lt8.

Thanks

 

curious as well...in for later

 

No.

 

So what kind of upgrades would justify this? or is it just not worth doing in general? I've tried searching, but i only find HOW to do it.
Either way im converting my Rails to AN Fittings.

 

When you require some very large injectors it would become more applicable. Stock injectors (680 is pretty close to stock), its not worth it.

You'd be needing a turbo upgrade and some 1200-1600 cc secondaries and something like 720-960 primaries before I would consider this a necessity.

If you're going to -AN anyway... might as well, the difference in cost is pretty minimal.

 

As long as you get a pressure regulator with two ports, you can always do it later...

I've got a BNR stage III, a Walbro Pump and -6an lines with the rails in series.... I got NO problems with fuel delivery even at 15PSI with 1600 secondaries.....

zkeller's 500+RWHP Third gen has the rails in series and a single SX FPR with a Supra Pump.... quad 1000 injectors, No problems.... HOWEVER.... we suspect he's about at the limit of the pump and lines.....

THe ECU doesn't really matter.... He runs a SICK i mean friggin GNARLY Autronic ECU and I'm runnin his old Haltech E6k

 

First of all, that MSD fuel pump ($80?) doesn't even flow more than the stock FC turbo fuel pump.
Get a REAL fuel pump!
