50 trim on stock fuel

[FE Srt4]

Hey guys,

Was thinkin of goin ahead and slappin your 50 trim kit on my car. Thing is I will be staying on the stock fuel system. Ive heard of many doing this and read your info on your sticky about this. So all I really need is just the intake and BOV and I can see that. This is perfectly fine to run on a stock fuel system correct? For how long?

Is there really no need for a boost controller? Or SAFC on the stock fuel system? If this is correct am I to hook up the turbo with the stock vac lines from the soloniods? Or do I hook it up without them. Thanks for all your help guys. Really lookin forward to doin some purchasing from you.

it'll work fine. Just don't go over say 12psi or so

[FE Srt4]

Thats what I have heard is to stay at 12. Wont I need a MBC to do this?

Just did some calculations too about cost. After the 50 trim kit the BOV and UPP and the Intake the cost of getting this kit without fuel is the same cost as getting Stage 3 no toys (I get a discount).

So now im thinking of the differences. Mopar is plug and play but no warrenty....where as you guys will give out a warrenty with your turbos and will work somethen out im sure if somethen went wrong 1500 miles after the turbo install if somethen broke (uhh Farani )

This setup would be fine. Get a wideband and turn the boost up to more than a 11.9 to 12.2 AFR and you will be set. You will quickly max out the stock injectors, so you might want to consider picking up some bigger injectors and a fuel return kit so you can mimic idle fuel pressure so it doesn't run like crap. Without a fuel tuner of some sort you will just end up being super rich and not making all the power that you could by leaning out your mixture.

This is what I am thinking about doing as well, at least until I have the money for a fuel kit. Putting in a bigger turbo at first and getting the other mods when I have the money.

[blu04srt4]

i'm preparing to do this as well. i thought long and hard about the stage 3 kit, but i can make more power for less money with the 50 trim. for now i'm just gonna get the turbo kit with the rc 750cc injectors. i'm not looking to get 500 hp, its just way to hard to put it to the ground. what's the expected 1/4 times from this setup? i already i the 3" intake, and 3" exhaust.

I personally wouldn't go that lean . I play prefer to play it safe 11.2 tops.

Big turbo is a good mod. Makes driveability much better

[FE Srt4]

So wait.....now I should get a SAFC when I buy the kit too?? I dunno im starting to see that stage 3 no toys would be the better route for me since you dont have to worry about it so much.

would be nice if AGP chimed in and gave some info....

[srtowner]

They probably have not spoken up because this very question has been asked several times in the AGP TURBO section of the forums. I know I am going to get flamed for saying this but people need to do a little research and use the search function. It was put there for a reason.

[FE Srt4]

I did research and plenty of it......but how am I gonna control the boost if I just throw a kit on my car with stock fuel. Im sure I will need alot more then an Intake and a BOV. Thats why im trying to get the info. Not like im some noob to the forum. But when I cant find some of the info I need im gonna post and im not gonna look through every single post in AGPs section to find some of these answers....thats why its a forum

[srtowner]

Well sighhh.......If you put the light spring in your wastegate you should only be running around 7psi of boost. Then from there you can add one shim at a time till you get 12psi. You do not have to have a BC to run the kit. You can run boost directly off the Wastegate,it is not ideal but it will work fine. The external wg the comes with the AGP turbo kits has alot of differant springs available for it to control boost levels all the way from around 2psi all the way to 20+ psi. From what I have seen on my SRT you will have a more stable boost curve when useing just the WG. In fact when I want a lower boost level I just turn my Apexi AVCR off and will be running around 12psi. I appologize I know you are not a noob on this forum, I just get tired of seeing the same ? asked over and over again.

[FE Srt4]

Hah thanks alot for your info dude. I understand about the search thing. I get tired of looking at the same "What exhaust is best" "What intake is best" What BOV is the loudest" threads so im with ya man

Very good info though I hadnt heard anything about the different springs that came with the wastegate. If thats the cause that WGA kicks ass at least in my opinion and im sure AGP's.

I might just have to say goodbye to the Stage 3 plans. Is it smart to get a BC at all? Even after getting the fuel? I dont drag race at all so im only worried about keeping the boost safe. Or is it best to just switch out the springs on the WGA?

[2tirefire]

11.2 is way conservative, but definately understandable to be on the safe side. I think we all can agree that keeping it under 12 afr is a good idea. You cannot just throw 750cc injectors on your kit and expect it to run......well it will run....but like shit. You need something to make it run at stock fuel delivery at idle and in normal driving......that is where a 1:1 fuel return kit comes into play. You will be able to mimic stock fuel pressure while in closed loop, but when you go into boost you will reap the benifits of the 750's. Still 750's are super big to go with without a fuel tuner. I chose to go with 650cc injectors (RC) and a fuel return kit. I plan on running a MBC and hopefully running close to 18 to 20psi with a safe 11.4afr. This setup should be good for around 360 to 380whp....lets hope.

with 03 car on 05 stage 0 cpu and stage 1 injectors i am running 14psi and a/f ratios are right around 11.5 at redline in 3rd gear.
