Default Steam Turbocharger Performance Results!

We thought that we would start a new thread for our Steam Turbochargers. There has been quite a bit of positive feedback from our customers and we want to provide a place where people can come to get an idea of the performance people are getting from the Steam STX 67, STX 71, or the STX 20G-R.

Post everything you have here: dyno plots, build specifics, etc. Don't be shy. There is lots to share and lots to learn. Perhaps your posting will help someone else or lead to tips from others! You don't need to be producing over 500whp to post here. Some will be interested more in spool characteristics than they will top end power. Others will want to see that peak power. Bring it all. Specifically, be sure to post the following:

Turbo model, dyno plot, supporting mods, etc. With the variety that is out there, this is sure to be interesting.

Default Stx 71

Initial dyno results of the TD06SL2+3071:

Top end feels strong and the plot agrees with this. Load is steady up top even though boost drops off. Car pulls hard all the way to 7k. Could try revving it further but haven't done that yet. Spool is not super early, but that is expected with cams and non-AVCS. Power comes on by around 4k so it is still a solid 3k of usable powerband.

Below is a comparison to the 2.0L with TD04 and VF39. Overall shape of the curve is similar with the larger turbo and larger motor, but the power is much higher. Little to nothing is lost on the low end of the powerband so it still feels fairly good around town but now it really takes off once you get the rev's into the 3k-4k range and above.

Default STX 67 Tuned

He said that with similar set ups and turbos, he usually only sees 330whp at most on pump gas. The mustang dyno numbers are 354whp and 337lb-ft torque. I will post a more detailed write up on the appropriate thread.

How many of these turbo's are out there? Only 3 results so far?

I think getting it into a list format like this will be useful for comparisons:

Hi NASIOC,

We finished building our JB STX 76 prototype. It is designed to satisfy those trying to hit the 450-500 whp with a stock location turbo. It is based off of a GTX3076R compressor wheel with a TD06SL2 9-blade turbine. We designed a new compressor 3" anti-surge housing that is compact enough to really be stock location.

Here is the GTX3076R compressor map. FYI: with the JB center vs the BB center as Garrett testing their turbo, there will be some differences. The surgeline at higher boost may shift more to the right, and the JB turbo will be less efficient at higher back pressure rations.


PM us if you have a built motor and are interested in testing our STX 76 prototype.

Thanks,
Sam

That being said, what is the expected power of the STX-71 then?

What loses do you see using the JB over the BB

The specs for the STX-76 still stand?

Yes, those specs are correct.

It should be able to make the same peak power. The compressor wheel can flow what it can flow irrespective of the JB vs BB center. If you have a well designed intake, exhaust, etc., I think there won't be much lost JB vs BB. If you have say a lot of back pressure, the BB turbo version will be more efficient. That is all.

Thanks,
Sam

A couple months ago, some of you may recall that we announced we were working on a new prototype turbocharger. Below you will see that turbocharger; the Steam STX 76 a journal bearing 76mm turbocharger mated to a lightweight 9-blade turbine wheel with a 3" inlet. We will keep you posted when we have dyno results.

Steam STX 76 is on the left A stock TD04H on the right.

We a few interested parties. Please PM us with the details of your car and the time frame in which you can get some results up. We are expecting some big numbers with this turbo and would feel bad if it broke someone's stock block.

Big thanks to Ed @ Eqtuning for a great tune. Him and his team were amazed and completely surprised at the power output of this turbo. We were originally going to go with the AEM CAI but the turbo was maxing out the MAF readings so we had to go with the KStech big maf intake. We also had to go with a slightly softer wastegate spring. Money well spent and the car pulls like a champ, especially up top.

I would have liked to have seen slightly faster spoolup but the amount of power mid to high more than makes up for it. The current wastegate seems to hit 18 psi and slowwwllllyyy get up to 19 psi. Ed believes that with an EWG, this turbo would "shiiinnnee." Our power expectations were surpassed and then some. I highly recommend this turbo (Garrett GTX compressor) to anyone looking for 20g typer power levels.

Below is the Dynojet graph:



And the more realistic Mustang dyno numbers:
