I took my SRT-4 to the dyno!

[mpboost]

So after putting 54k miles on it and having it nearly 3 years I finally put it on the dyno:



The car is equipped with Mopar Stage 3 with the Turbo Toys option. I was running it in High Octane Mode on Sunoco 116 (I can also run 110 octane and hold HOM though).

I have a good number of mods to the car, but engine wise it just has the basics:
-MPx Intercooler
-Maxxfab Dual Exit Mufflered Exhaust (Turbo back)
-Maxxfab Stage 3 O2 housing
-Injen Short Ram Intake
-DCR Oil Modifier
-AGP Stage 3 Wastegate Actuator
-JMB Powdercoated charge pipes w/HKS blowoff valve

Just thought I'd share.

Very nice! The agp wastegate is a must for s3.

[2.216VTurbo]

Very strong, nice

[turbovanman²]

Very nice power,

[glhs727]

nice numbers for a s3 car.

Close to 375 horse and 400 ft lbs!

Is that the big or small i/c setup?

With the dcr port job on the comp and ported intake I made -10hp and -10tq on pump. But I was boosting 27psi at the time. Does it feel like your running out of huff up top. Other than that I'm very similar to your setup. I even have the mopar 2.5 inch though.

Good #'s though. I know how it feels to have hard work pay off.

neoned: if you didn't dyno back to back, 10 hp is within acceptable error so there is no guarantee those mods did anything.

It's a large IC.

I actually just bought another brand new Stage 3 turbo and it just got here today. I am going to break it down and ship the parts off to a couple vendors. I am planning to have the turbo upgraded to an FM Enforcer 3, and then it is going to Darrell Cox Racing to have a 3" bellmouth w/antisurge ports added to it. I am still debating what I will do with the manifold. Right now I am either going to send it to Darrell Cox or Realtune to have an external wastegate added.

My new goal is to make 370-375hp on pump gas and 420-425hp on HOM.

That is a pretty nice graph, and a very nice powerband too. I bet that is a lot of fun on the street.

Hope you plan on a ported head or upgraded turbo.

Reading owns me . But I was right .

[stage3]

I have the E3 turbo, installed it last year. Finally got a ported exhaust manifold for it. Realtunes manifold but still with internal wg.

just cause Im curious, but why would you put a modded stage III turbo on, instead of a 50 trim?

[stage3]

Less lag and broader powerband.

[10G OMNI]

What PSI? great if your boosting 16 not so great 28 and up

[t3rse]

the chart says 23-24....

I feel sorry for these SRT folk who think they need ported heads to make 500 hp....

Just like stage3 pointed out, it's all about powerband.

50 trim turbos tend to make better peak numbers, but the Stage 3 turbo makes a lot of power underneath the whole curve. At the track my 366hp Stage 3 performs more like a 390hp 50 trim would.

Yup, 23-24psi spike but the PCM pulls it back to 21psi real quick, and then it tapers down to 19-20psi near redline when the backpressure starts to overpower the wastegate.
