ok guys... ive read so many posts on fuel... blah blah this... blah blah that... but what i really wanna know... is this...

for a moderate boost daily drivin street spankin LS DRAG 3 turbo kit... what is the best way to go?

1) stick with the 12:1 FMU and Airtex fuel setup. (i know some of you would tell me to ditch that pump and upgrade it)

2) run bigger injectors (like 310's) and change the fuel ratio to 8:1 or 10:1 if i remember correctly.

3)keep the FMU setting at 12:1 and run an intank pump instead of an inline. ive always wondered which was better to use... inline or intank!

keep in mind... i already know standalones are good to go.. but im running 5-7 lbs only. so i shouldnt need to spend all that money on one.

also...
between the drag 3 setup and the injector/ration setup... which is alot safer in terms of detonation?

 

for 5-7 psi the stock injectors with FMU, 12:1 disk and inline pump will be fine. However if you want to crank the boost up to say 10 psi I would get 310's and lower the rise ratio to about 8:1.

 

i would choose #1. although it won't make as much power as other setups due to the FMU raise ratio is high, cause the car run very rich.

personally i think intank pumps can never feed any kind of forced induction setup, they are way too weak, you know that just by looking at how small the pump is. if you must go intank, go for Endyn modified bosche pump. the downside of inline pump is they are really noisy, I mounted mine in the rear next to the fuel tank, i hear it all the time, because if you don't hear anything, the pump is dead.
