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

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.

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.

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.

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 ...
