50 trim + stage 2 inj. + return line - Do I need a Walbro?

[Gmanigio]

Thats my question. I know a return line + st2 inj are good for 400whp, and thats more than enough to get me started, just wondering if I would need a walbro.

I would also look into removing the bottleneck in the system.

Thanks

[cokey]

noob? where's the bottleneck.. why should it be removed..?

[SPECJ]

Of course you do. You could put 495834085cc injectors in your car, but if you can't supply the volume of fuel to the motor, it's not going to do you any good.

Actually stg 2 injector's is NOT more then enough to get u over 400hp. 350-375 sure but 400 w/out running out of fuel? Not exactly. I strongly suggest going with at LEAST rc 650's to push the fuel. No point in trying to over do stg 2 injectors if ur expecting that kind of power.

Return line and walboro pump are highly suggested items when doing a 50 trim turbo. With the amount of fuel u will be pushing through, u wouldn't want to rely on a stock fuel pump to be ur support.

Never said over 400HP, its good to about 400HP proven w/ a return line.

Thanks for you guys opinion, all I needed was a yes or no.

ok no problem......*ahem*.......... :no!:

[cokey]

so.. how much boost you think i'll be able to run with the stg 2's ? i'm thinking 15 lbs would probably make it feel like the stock 19-20 lbs.. is my assumption correct or far fetched..? this is with out the return kit.. that comes hopefully next month or so.. i gotta cop me that boomb fuel rail.. that things sweetness..

[srtjay]

i would not trust the stock fuel pump for anything over 330 whp.. its a cheap part. buy it and don't take the risk

[Gmanigio]

stage 2 injectors are good to about 15-16 psi when monitored with a a/f gauge. Anything more than you need a return line or bigger injectors. Stage 2 inj. w/ return line is good to 380HP safely and boost depends on A/F.

16psi is THE MAX I believe on stage 2 injectors. 400HP is pushing the limits of the injectors and not SAFE as Hozay (The Master) has said.

Not bad if your still saving for huge injectors. Its a good place to start if going big turbo and still on the stock cluth.

Was this supposed to be funny, sarcasm or what? I must have missed something here.

[The-Violator]

Yup I can vouche for the S2 injectors only getting 15-16psi safely.. With return line and walbro I could only go up to 17ish. Needless to say I was disapointed. So I just got me some 750's and called it a day :)

Why disapointed? NOt enough power?

[cokey]

oh sorry guys.. i meant 15 lbs of boost.. not fuel pressure.. i was running 19 lbs with the stock turbo.. but after the big one goes on there i think 15 is good enough..

[jmcmil6]

i think some of you guys are not completely understanding what violator and hozay are talking about.. you guys should listen to them they both kno what they are talking about.. if you want to learn more about injector sizes/fuel pressures and how they relate to hp go check out RCengineering's site they have an injector calculator that should help you understand...

basically when you use a fuel pressure regulator and start squeazing more fuel pressure thru an injector there comes a point where they lose their efficiency, thats why they dont suggest using a small injector and trying to make it "too" big...cuz you dont want to start distorting the intended flow parttern of an injector.. especially on a 50trim at a decent boost level.. cuz it will make it much easier to kiss your motor good bye

I'm so glad we talk about this on the phone. :D

WOW! what you have learned in the past year has made you a better person. Good shit Hozay!

[L8SHIFT]

Alright Hozay I got a question. Do you need to cut some wires to install the 750's. I just snapped in the Stage 2's....

u can actually splice w/o removing.. but personally i would solder(Sp) the new one's in place of the old one's.. unless you "really" need to change them back easy for some reason

[SPECJ]

Guys, you can buy injector harness' for the 750's. There are several vendors outside of the forum that sell them, such a central florida motorsports. They are cheap and dont require you to cut anything (connectors on both sides).

nice.. personally i wouldnt like the clutter.. imo

Exactly what he said..I actually have these installed on my car. If you look closely, you can see how they are connected (white wires)

YOu don't see the clutter underneath the cover so its no problem. Just gotta make sure the clips on are on tight!

I myself got them from CFM. For now, we sell the rc's that have to be soldered but its no biggie. I can get my hands on those injector harness's myself.

i jsut ordered a split second map clamp and was thinking bout stage 2 injectors with stage 0. Also i am going to upgrade the fuel pump and a boomba fuel rail. Eventually make it a return system(month or so). I have agp wastegate, iceman cai, iceman 60mm tb, atp pressure pipe w/ rfl bov, bop, custom 3" dump exhaust no cat, nology hot wires, ngk iridiums( bout to order denso itl 20's). What would you suggest as far as injectors and all? stage 2 or other? what power should i expect?

[04Srt-4Dodge]

what kind of catch can do u have hozay??

sounds like ur on ur way to 300hp

If your gonna do things, do them right the first time...RC injectors 650 or 750s, piggy-back (emanage,dtec,safc) fuel return kit (AGP among others) and walboro pump. The boomba fuel rail is nice. I am thinking about it myself but its not a "have to have" thing right now for you.

Thanks for the help guys. I just got the 750's installed and soldered in. Looks like I still need a return line for the 750's. It's it seems to be needed to help us get more power out of the car. I have a 50 trim with a 48 A/R on an 05 SRT4. I know that I'm not going to get the big 400hp numbers like the guys with the 63 A/R's. Right now without the return line I'm making 330hp Rich 11.5 High boost (23 Psi) 10.0 Low boost (17 Psi). Hopefully the return line will lean it out and pull a few more ponies. What do you guys think? Oh P.S. I do have the fuel pump, SAFCII and a MaxxFab Borla exhaust, I'm wating for Scott to release his new quiter exhaust kit. We've also been playing around with the Stage2 and Stage0. I'll let you know which one works better. So far Stage0 has been doing well.

Do you have a stock downpipe? That alone can really choke your turbo. Since your waiting for the new maxxfab exhaust, dont bother spending money on a downpipe. 10.0 is EXTREMELY rich! Definitely bring that up to at least 11.2-11.4 for low boost. High boost with race gas would be around 11.8-12.0

A return line will help you significally with those injectors. 750's are VERY big injectors and seeing your turbo is a .48 a/r rather then .63, your gonna need alot of fuel pulled back.

[jb4short]

My 1.8L Sentra makes 126hp on PUMP gas without all those "Fluff" mods.

I got the MaxxFab 3 inch D/P with high flow cat. How many ponies do you think We'll be able to pull on pump gas in high boost?

You should be around 360-380ish range on pump with those mods. I wouldn't go higher then 20-21psi on pump w/out a return line though.

[jmcmil6]

hey l8shft... what are you using for tuning again? are you going to be in town this thanksgiving? im gonna be in town(@ my cuz's house).. if you have a wideband or something of that nature and something to tune w/ i could help you out a bit... hey hozay.. u gotta member the elevation where he's at is gonna kill him.. his car will always try to run rich, so its gotta go much leaner than that... but i def agree i wouldnt mess w/ the 750's i think thats the reason so many of the big turbo guys are getting the "stumble"
