TurboMick Member 52 Member For: 14y 10d Gender: Male Location: Perth Posted 11/08/11 12:50 PM Share Posted 11/08/11 12:50 PM Hey guys, prepare for a long post I've got a BA with the usual mods and have around 370rwkw, and I'm not too sure whether to go BA Plazmaman (or equivalent) plenum, or FG style. Any ideas?I can get both for around the same price, so figured the FG one would be the way to go as people are having good results with them.I'm a mechanic, so fitting will be okay, but was wondering if the FG style plenums require any mods to the head etc to fit (I'm assuming they wouldn't)?Lastly, I'll probably fit an aftermarket fuel rail with twin feeds and a second 044 at the same time, do people usually go -6 or -8 lines?Was thinking -6 supply and -8 return, but I'm open to suggestions.Cheers in advance Link to comment Share on other sites More sharing options...

orangeute338 Suspended 260 Member For: 16y 8m 8d Gender: Male Posted 13/08/11 01:22 AM Share Posted 13/08/11 01:22 AM you dont need a -8 return that's massive, I made up a rail for a mate putting a fg manifold on a ba, we just used -6 feed and -6 return. the head is the same as fg so bolts up the same. if it was me instead of running 2 fuel lines. I would just have a joiner block at the pumps then run a single -8 line to the rail and a -6 return, and I would have one of the pumps run off a pressure switch so kicks in at 5psi or so..or just run both pumps but have the voltage regulatored then with a pressure switch give full volts at 5psi or so...keeps the noise down and doesnt spend half the time just pump fuel up and back.

TurboMick Member 52 Member For: 14y 10d Gender: Male Location: Perth Posted 13/08/11 02:38 AM Author Share Posted 13/08/11 02:38 AM Cheers guys, I think I'll just go -6 as suggested. I'm going to keep it twin entry with the return in the centre simply for better pressure distribution.I won't be starting it for a while but I'll put up some pics when I'm done.Cheers.

FG style or front entry. All and any opinions will be appreciated Link to comment Share on other sites More sharing options...

Dont see many people changing them though from what ive heard so maybe not much to gain compared to cost? Link to comment Share on other sites More sharing options...
Dillz Three pedals are better then two..

Can't just be because they are easier to plumb up?? Link to comment Share on other sites More sharing options...
Worm A much better forum Silver Donating Members 3,808 Member For: 16y 8m 14d Gender: Male Location: Victoria Posted 11/01/12 12:04 PM Share Posted 11/01/12 12:04 PM I reckon If they designed a center entry with larger volume (ie. FG style but bigger volume) it'd be perfect! Link to comment Share on other sites More sharing options...
