The SteamSpeed STX 76R Ball Bearing Turbo for BMW N55 PWG is a complete turbo upgrade for your BMW featuring a dual ceramic ball bearing cartridge and a custom GTX3076R sized compressor and turbine wheels.  This turbo is designed to provide early torque for a more stock-like response but with loads more power and power holding throughout the power band instead of falling off on the top end.

This turbo is designed to work well with basic mods.  With a larger front mount intercooler, downpipe, inlet, charge pipe, and low-pressure fuel pump, our testing shows roughly a 20% power gain vs the just the bolt-ons and the stock turbo with just 16 psi of boost.  The STX 76R compressor wheel does flow over 65 lbs/min over 25 psi, so it is plenty capable of making even more power than that.  With sufficient fueling, the STX 76R is capable of making 550-600 whp.

The STX 76R installed on a N55 on an engine stand:

Turbo Specs:
- Compressor wheel: 58mm inducer, 76mm exducer, flows ~67 lbs/min
- turbine wheel: 60mm inducer, 55mm exducer
- compressor housing, new casting, stock-style
- turbine housing, new casting, high-performance twin-scroll, +sized A/R vs stock

Car Under Test:
This data is from a 135i with PWG-style N55. We took a stock car with the base MHD map, measured performance, added basic standard bolt-ons, measured again with the MHD 2+ tune, and finally added the STX 76R and measured again after tuning for the turbo. The idea was to take a stock N55 car running pump gas and a conservative amount of boost, and add a minimum set of bolt-ons to support a turbo, and then add the STX 76R.

Modifications:
"Stage 2" upgrades: larger front mount intercooler, catless downpipe, charge pipe, inlet, and MHD stage 2+ tune. Everything else was stock including fuel pump, ect.
Post turbo modifications: all of the above + STX 76R + tune

Tune:
The turbo tune was done by Zack at 22rpd on their DynoCom dyno with pump gas and ~15 psi target. Zack is a long time BMW tuner well-known for high-power turbo builds on E36 and E46 cars.

Result:
Stock: 310 whp, 307 ft*lbs
Stage 2+: 366 whp, 436 ft*lbs
With STX 76R+ turbo: 429 whp, 416 fr*lbs







Conclusion:
The turbo basically accomplished what it was designed to do, respond quickly, and make much better power than the stock turbo. With a few boltons and the SteamSpeed STX 76R, a stock N55 car made another 120 whp, or around 40% more power. As compared to the car with boltons, the car made another 60 whp, or around a 20% gain. Our turbine housing also made a nice torque and powerband. Our new housings also allowed the powerband to hold on much longer to red where you would normally see turbos with stock housings fall off.

Furthermore:
As we continue testing on other cars, we found that fueling was limiting this setup, and adding a Walbro 450 LPFP, we were able to see around 450 whp and 450 ft*lbs on pump gas and 16 psi, so we recommend doing that upgrade as well as the basic stage 2 stuff.

Next up, we'll push it to the 20-25 psi range on pump gas to hit closer the turbo's peak flow. The turbo would flow the most around 25-30 psi, but that will more than what pump gas can provide.

Amazingly great product!
Color: Grilled color
I’m not just saying this, ok, this is not hyperbole: this is THE best nylon bone for chewing that I have ever purchased. And you get TWO of them for relatively less expensive than most chew toys give you one! I have 2 golden retrievers, and if you know goldens, you know that they are some of the most relentless and powerful chewers around. So I can’t give them almost any toy other than rubber stuff or it will be destroyed in a period of time that doesn’t make it worth it. One of them even figured out how to destroy a supposedly indestructible toy made out of kevlar! She was able to get into it through the seam, which is not kevlar ha ha. Anyway, I digress; I never even considered nylon chews because they suck! Usually. Usually my dogs in the past have lost interest with them in less than a day. I took a chance on these mainly because of the novel shapes, the fact that they give you two, and the low price. Both my goldens LOVE these! Not just for one day, but going on weeks now! I don’t know if it’s the flavor or what, but I will see them gnawing on one of them at some point every day. And they CAN’T destroy them (I knew nylon was good for that, but it was the “who cares” attitude of my previous dogs toward nylon that kept me away). Both the “ribs” and “steak” (quite clever) are a bit worn on the edges now, but they look like they will be around for years. You can’t go wrong with this product (unless for some reason your dog does not like the flavor, but the flavor seems to be what draws my dogs to them). I highly recommend this (these) as the most cost-effective chew toy I’ve ever purchased.

Great for larger dogs
Color: Grilled color
I think they were heavy duty and durable, but they were too heavy for my dog. The seller was excellent though!

It ok but a bit small for my golden and I have to supervise him.
Color: Grilled color
I don't recommend. Too big for my small dog. Too small for my big dog. They have similar bones but these just seem odd. ** WELL actually after some time they both will chew on them, especially my golden. Do be careful watch the dog while chewing. My home health care aid thought they were real. they are holding up well.

Finally a chew toy my aggressive chewer can’t destroy
Color: Grilled color
I’ve gone through countless “indestructible” dog toys that lasted maybe a day—sometimes only minutes. My dog is an aggressive chewer and treats most toys like a personal challenge. These Fuufome chew toys are the real deal. Right out of the box, you can tell they’re made from tough, high-quality nylon. My dog went to work on them immediately, and days later there’s barely any noticeable wear. No chunks missing, no sharp edges, and no mess on the floor. That alone puts these way above most toys I’ve tried. I also love that they actually keep my dog busy. Instead of getting bored and looking for something else to chew (like furniture), she’ll settle in and happily gnaw on these for a long time. It’s been great for mental stimulation and for redirecting destructive chewing. The fact that you get two durable toys in the pack is a bonus, and they’ve held up exactly as advertised. If you have a large breed or an aggressive chewer and you’re tired of wasting money on toys that don’t last, these are absolutely worth it. Highly recommend—this is one of the few chew toys that has truly lived up to the “indestructible” claim. 🐶💪
