This is alot more simple than you guys are making it.
My kit rocks and everyone will love your car because of it , so just buy it.
no shit! It's really simple to install from looking at the directions.....and I think it's worth the price $360.....I don't know how much other return line kits cost, but this price just sounds good, and comes with everything you need.
Like I said, I'll be buying one once I get the funds.
I believe it does have more pressure, but referenced to manifold pressure not ambient pressure. The stg 3 comes with a bigger pump and a 4 bar fpr on the rail.
BlackSRT-4U, Thanks for all the info! Nice to hear from people that have some hands on experience and info that makes sense. When are you guys getting the web site up? When I'm out of school I'm heading back to S. Fla. again... I'll finally have money to do something wild with my SRT-4 and not have to drive it everyday.
You are very welcome..
the site should be up hopefully soon.. it's getting re done completly..

I'll agree, even with a completely stand-alone ecm, this kit (method) is the way to go if you plan power beyond stg3 or w/ a big turbo. Returnless is not worth the head-aches or limitations.
umm...? try running your car without a return line or bigger injectors on a high hp (modified) car, and see what happens...
i am doing it now so what about it..... i have 750cc injectors with walbro fuel pump..... no return.... and what is supposed to happen to me because nothing is...... so be more informative

how many of you are runing high boost levels on a stock turbo with a returnless fuel system and notice lots of bucking and jerking at partial throttle boost? the fuel pump is having a hard time meeting the demands of the motor and the ecu is not compensating for the needed fuel.
Ive tuned a number of SRTs and notice that without a return system the air/ fuel ratios fluctuated a lot during partial throttles and lower rpms WOT. Yes it is very possible to properly tune a car with a returnless fuel system and as someone noted you need control over TPS enrichment and such.
The beauty of the return system with and adjustable fuel pressure regulator is you can run huge injectors and lower the fuel pressure to help them idle and because the fuel pressure increases with boost it compensates for fuel when it needs it.
Well the real reason for a return system is you could use a 1to1 fuel pressure regulator, per every psi of boost you'll get a psi of fuel pressure.
example big turbo SRT4:
at lets say 21psi of boost no return system with big injectors and fuel pump.
all you are doing is adding an huge amount of fuel since a 750 cc injectors is normally rated at 43psi not 58psi. if the car doesnt have a piggy back it will be pig rich. with a piggy back you'll have to take alot of fuel out which it will add timing which it means you'll make more power but it will NOT last long.. Detonation.
with a return system you'll be able to better tune the car for driveability as well as WOT, and not worry about taking out so much fuel out, since it will be there only when u need it WOT under boost.

hmm, hey smartass....did you read my post clearly?
I said: see what happens when you don't run a return line, or bigger injectors.

thanks.
first off i wasnt trying to be a smartass but i can if you want.....you were being a smartass to him if anything he was asking a ligitament question and you were being a smartass.... i was asking you to be more specific.... that is all so lets not start this on this thread....

And I hate to make you sound like a smart ass, but did I read your sig correctly? A 60-1 and ONLY 330 whp?
Wow... Stage 3 puts out more power than that.
I wonder if you are having a timing issue related to those big ass injectors on stock fuel pressure and you pulling out a ton of fuel on that safc.
Remember, the more fuel you pull on that safc, the more timing you will add. If you don't increase the octane, that extra timing will lead to knock, which will really screw your dyno plot (and lead to pulled timing). I would love to see your dyno plot.
The way i see it return line adds the ability to tune. See stock injectors run at static 50+psi (don't remember the exact number) where as the 650's and 750's like rcs are designed to run at 40 psi by using a return line you can rough tune for your injectors and then fine tune with safc or other method so you don't have to pull so much fuel with the safc. Plus when you install large injectors on a stock fuel pressure a 550 injector comes out 2 a 650 and so on becaust of the extra fuel pressure. So i see it as a way to compensate and tune for your injectors
