Biggest Best Turbo For Srt-4

[dannya88]

WUT IS THE BIGGEST BEST TURBO U CAN GET FOR AN SRT-4 LIKE THE OVERALL BEST TURBO PERIOD? AND THE OTHER DAY I WAS SEARCHING ON EBAY AND I SAW THIS GUY SELLIN SOME SRT-4 THAT DID 10's AND HE WAS SELLIN FOR LIKE 18K I THINK IT WAS BULL

[hozay09]

where's a link to it. Gotta see this one.

[psi chick]

it was probably andybuzz lol

[mo'sSRT4]

for the streets i think i would not go anything bigger than 50 trim. It is perfect for our car quick spool and puts down awsome power.

[N2MB]

doubt it, andy was running 8's

[psi chick]

doubt it, andy was running 8's

on the stock turbo too...forgot about that :all_cohol

[TopOfNewYork]

but back on subject i've seen nothing but great things come from the 50 trim

so that would be my route

[Richyc]

from what it looks like 50trim or s3r are where im going. most like S3R by next summer or sooner.

The good ol AGP 50trim is agrueably the best turbo for the street.

It spools fast, loves pump gas, and hits very hard....

With the AGP 50trim I dynoed 448 on pump gas... Then cranked up the boost,
fed her C16 and laid down 492hp/507ft torque...

The car trapped 120mph on low boost and then trapped 125mph on high boost..


The 50trim makes for a mild street driver, that gets great gas milage....
but up the boost and drop the hammer and your SRT will convert from a econoshit box into a RUNAWAY FREIGHT TRAIN! With neck snapping and crazy torque steer! A car that can trap 120+ is a terror on the streets..

It in my opinion is the best all around choice... But alas, I maxx'd it out at 30psi, so its a new GT40 kit for me.....

Question lets say if you were to take that 50trim off the log manifold and put it on a tubular manifold would it make more power? From what I have seen the LOG manifold does not use all 4 ports to spool the turbo it only uses 1 port. Which slows down the spool up time also wouldn't the EGT's in a LOG manifold be much higher than the tubular? After talking to few companies out here in Cali reason many companies go with the LOG manifold is because they are cheaper to build versus the tubular or equal length. I personally think I would put that 50 trim on a tubular manifold and most likely it will make more power and spool faster. PLEASE PEOPLE keep in mind I am not bashing anyone products or nor am I saying one is better or worse than they other. This is for people who want to know that difference between the 2 and for knowledge sake so one again PLEASE DO NOT TAKE THIS THE WRONG WAY.

[mo'sSRT4]

I respect Lucy very much so even though i have never talk to her. I seen her post in many different threads and she always comes off nice and helpful so that is why i am asking these questions. THANKS

[LittleMT]

There is much debate over the manifolds, whether they be log or tubular....

We have obviously proved that a log style can make big power, and others have done so with the tubular design.

The manifold that AGP sent me was ported and cleaned up some. Did this help spool time? Not sure but I do believe it played a role in the high hp numbers my car got, because at that point in time, those numbers were amongst the highest hp numbers made on a SRT, now, many are making big power.

A 50 trim spools pretty darn fast considering its a bigger turbo then the stock (dare I say it) toy hairdryer.

If I put a log style manifold on would the performance have been better?
I don't know and can't rule it out, I can only say, AGP did their homework, and we have made tremendous power with the log style, and it hasn't cracked, atleast not yet.

My car trapped 125 when the DA was 6500ft with this manifold, I have argued that this car would trap 127 - 128 at Sea Level and a track that is properly maintained. The cars ET was only a 11.85, due to a poorly prep track, and not the best driving skill which led to subpar 60ft times.

But on the street the HP was there. The RED car literally slams you into the seat, one passenger said they thought they got punched in the chest, another said it felt like a Runaway Semi Truck hit us from behind.

This car on the streets of Albuquerque regulary made Vettes, Vipers, LS1's, look stupid, because I didn't just eek out wins, rather 'The rout was on baby!'

The torque steer is tremendous and quite thrilling actually. And yet this car was suffering some due to the altitude conditions of Albuquerque, which unlike Denver, Albuquerque is a mile high desert, making it somewhat unique.

Because on top of being 5300ft up, we regularly see temps of 104, 105 in the summer, pushing the air density as high as 9000ft....

And for whomever doesn't believe that this type of air hurts the performance of your car, then please kindly drive up a Mountain and see if its perfomance doesn't suffer....

So again, the AGP log manifold works. This isn't to say that the tubular manifolds don't or are not better, I really don't know, but rest assured,
had I of given you a ride in the RED SRT, the last thing on your mind would be
what kind of manifold I am using..

Are you going to stick with the LOG style or maybe one day might try out the tubular manifold to see that difference? and thank you for the replay.

I just purchased a brand new AGP GT40 kit...
I have no plans to try a tubular but I will never say never.

Should the Log manifold crack on me, I may try another design, I really kinda like the ATP manifold that Nivo and SrtGurl use....

I also remember that mi Amigo Hector (Exhaust Depot), has designed a very sexy tubular manifold...

It would be a interesting test, to run on the dyno with the log, then with another design..

I'll give this some thought...

Awsome yea hector has an awsome manifold, i would love to see the differences in the 2 that would be awsome. Glad to see that there are open minded people with SRT4. Oh and yes congrads on those great #'s with the 50 trim I hope my friend here jose can make the same #'s as you that would be cool. Glade I got to talk to you a little I heard many great things about you, nice too meet you.

[xtremeboost]

Well , we have tested-out the manifold VS an AGP unit (using the same turbo ). We did not have time to place it on a dyno but it did feel to make a bit more power at the same boost but we do not have any #'s ( I think it would be Tq more than anything ) . Over all, like I always tell people - having installed the AGP and ATP manifold based kits they ALL work and work very well . Not everyone will want our manifold just because the turbo doesn't sit high where it could be seen or for other reasons .

No one should at anytime take anything away from the AGP kit !! We have installed and work on many cars which have that turbo kit and we havn't had any issues and they do make power !! For some of those guys that have had the AGP or other kits and have switch to ours its been a choice they made because of a few reasons , first is looks then theres function ! Some just drive in another customers car with our kit and deside they want to switch .

In the end people will sometimes make their choice based on personal reasons and no one will tell them otherwise ...

YOu ladies wanting these big turbos and stuff. Make sure you have a beater car cause your car will go boom when you run high boost often on the stock pistons. THe stock pistons are not ment to run high boost which is why the ring lands break. Just ask hozay about it. :)

Mine currently has cracked lands after 3 years of having a big turbo. I just did not beat on it like many of you do. :)

Yeha but on a serious note. Stay at 18psi if you want a safe big turbo setup that pulls pretty nice. If you go 23psi etc, go with race gas. Its not always the detonation that causes the lands to crack. Hyperutectic pistons are used because they cast great with about a 1% waist factor unlike regular cast pistons which have a great scrap waist.

[ptperformance]

I would go with the 50 trim or a gt30r set up. I have cast steel manifolds and so far they work great. I am getting a custom equal length tubular titainium/inconel manifold made in the next few months with slip tubes so there will never be any cracking of the set up, but it will be big $$$. If you want to go after big power you will need a tubular set up. I sell the basic 50 trim set up for a great deal and have other options avaliable. Let me know what it is you are looking for and I will do my best to get it for you, thanks.

How you doing hector (person who got mad at me for wanting his IC so bad).:slap:

So Water Injection would be a good thing to have to keep detonation away to save the pistons rings? I plan on running 24 psi on my turbo setup but that is with WI. On a daily cases when i do push the car i run 19psi and that is with WI on as well. What I am doing is that safe?

[N2MB]

personally im a fan of the log manifold soley because it can take the heat and not get kicked out of the kitchen.tubular manifold would be better but not on a street application.although water injection drops egts considerably i think that the tubular mani over time would crack.on a race only car i would say tubular but in this casemy vote goes to log.

hey mo im offended that you moved to cali and didnt let me build your car:2up: :D

[Gmanigio]

Whats the difference between stage 3 boosting 23-24 and big turbo boosting 23-24. Is it safe for stage 3 to boost 24 as it is big turbo at 18 ir is stage 3 putting more stress at 24 than the big turbo at 18, or is it a HP thing more than the PSI?

hope i didnt confuse anyone.

Sorry had to do alot of stuff myself and a friend of mines. I'm just having problems tuning the all mighty power paq :mad: . I am coming to NY on friday so hopefully I get to see you :giveup: . BTW how is your daughter now is she 110% good?

It depends which size big turbo your talking about stage 3 can push 24 no problem but i would look into water injection system because I think the manifold is considered log so the EGT's will be little higher than the tubular manifold. As far as pushing more air Yea a bigger turbo will push little more air than a smaller turbo. How much more it's hard to tell. So lets say you have a 50 trim and a stage 3 turbo they both pushing 23 psi 50 trim will push more air because its a bigger turbo, but is you push 50 trim on 18 psi and stage 3 on 23 psi I dont think it will be huge. I hope i answered your question.

[ilumo]

I have a GT40 setup with 750cc injectors, aaronneon return line, and a few tuning (dtec fc/wideband) goodies. It is currently at 22 psi, and yeaps, it pulls like a RAPED ape, and for me, it isnt TOO laggy. Yes, you have to wait a second before the power hits you, but when it does, it hits HARD. And I know what laggy is/isnt. I came over to this SRT from a 03 cobra, so that was instant power. But 400 whp on a 2900 lb car, is insane!

[sriquixotic]

whats the difference in the gt40 and 50? 40 has less lag right? and would make less power than the 50? could you please explain to me, im trying to decide of which setup to go. i dont wanna be pushing a 50 trim and have
400+ hp on 24psi and have shit break 2 years later.. you know what i mean? i dont abuse my car either. thanks a lot


edit:
GT40/T350 (stage 5) This is a big turbo. 600whp is possible if you dare to run over 35 psi. Full boost around 3700-3800.

ic, i just read this from agpturbo.com lol, i guess i had it backwards, gt40 makes more power than 50...?

[04Srt-4Dodge]

Hey i have 2 questions, what is the extreme boost and if u were to get the 50 trim do u need anything else to make it run well on our cars?

Of course you need things for the car. THe more air you pump in the car, the more you fuel you need to feed it... so you need a bigger fuel pump, bigger injectors, a return fuel line, some kind of adjustable fuel regulator... and then you will need to breathe better, so you will need a big intake, big turboback exhaust, make all your IC / Turbo plumbing bigger... Then you need to cool down the air charge to avoid high cylinder temps, so you need a bigger/more efficient intercooler, or some water/meth injection... Then you definately need to monitor your car to make sure you're not running lean, too hot, so you need gauges, and of course you need to tune it, so that the AFR is the optimal value, so you need a wideband O2 kit, some piggyback computer, and datalogging is nice too... ohh, and if you want to apply that kind of power to the ground, you need a better clutch. enjoy.

its makes it sound all not worth it, and jus get stage 3 heh.

[mo'sSRT4]

oh its worth it if your willing to deal with some head achs plus its not as bad as it seems. Stage 3 is awsome and is plug and play bascially, but if you decide to go big turbo just do one thing at a time, or try to buy a complete kit from one of the vendors of this site. Contact JAY at nevertomuchboost he is an awsome stand up guy and will help you with anything. I dont know which state your in but get in contact with jay and go from there.

[ilumo]

its makes it sound all not worth it, and jus get stage 3 heh.


It depends on what you want... you want good power? or do you want INSANE power.... stage3 will never get you the insane power levels... And if you approach insane power levels with stage 3, most likely you're going to have to get those things i mentioned anyway. RIght now, my GT40 setup is giving me INSANE headaches... sighhh..

[Screamin Demon]

It also depends on where you live. Us up here in the fine mountains of colorado don't have as much air as you folks down there on the beach. IMO up here the 50 trim is almost too big, full boost is almost at 4000, while a bigger gt40r will attain full boost by 4300ish. The base model 3147 is the perfect turbo for our altitude. 50trim is borderline and anything bigger will require a very good driver or some nitrous to spool it.

[ilumo]

true... you higher elevation guys are gonan suffer some lag.. hmmm.. but once the turbo DOES get going, it'll be the same.. :) I guess you gotta use some happy juice to spool up... or just be happy with your 3147 :)

[Screamin Demon]

Thats it, suffer some lag with a bigger and get big hp numbers, get quicker spool and suffer hp numbers or get a big turbo and nitrous and you have a happy median.

[mo'sSRT4]

they do not make 3147 turbo anymore.

I know that every car is different, but what about all the Turbo Civic and DSM's that have using tubular mainfolds for as long as I can remember? Does it have to do with the placement of the turbo?

A lot of those manifolds crack and the ones that dont are made out of a different material that can take the heat. Good ole cast manifold for me on any street driven car, race car gets my vote for tubular. Log manifolds are ok but not my choise because just like a tubular unit over time the log manifolds crack.
