We have updated our OBS turbos to the new style which is based on the popular s366sxe design.
Recommended injectors: 238cc/80%
Minimum injectors: 180cc/30%
Maximum injectors: 250cc-100%
It is here, we spent the last year working on updates for our popular TP38R turbo. We kept hearing about how great the s366sxe was... but with it being a standard rotation T4 turbo, it can be a little expensive to install on these trucks because it requires a "T4 mount kit". We wanted to see how a reverse rotation, drop in, 366sxe turbo would perform in our dual ball bearing TP38R turbo frame... 1 year later the TP38R 366 was born and the results are AMAZING! It spools faster, runs cooler, and makes more power. All testers reported how much cooler and cleaner their trucks run with the updated version. Some reported a 200 degree drop in EGT's. The power comes on so much stronger and quicker with this new turbo, which makes towing and daily driving so much better.
Even though the turbo still has a 66mm compressor wheel, it is much different. It is a larger, 7x7 wheel and is modeled after the 366sxe compressor wheel... same profile, shape, and blade style, except it is reverse rotation. It's not only bigger, but stronger, and has thicker blades, larger hub, and thicker backing, which makes it much less prone to fatigue and wheel burst.
The turbine wheel is also much larger, 73mm vs the old 70mm, and much taller with larger blades. It does not just share the same "dimensions" of the sxe wheels. It is the same shape, size, thickness, and blade profile as the s366sxe turbine wheel. Please see the pics below to fully understand how much different the new wheel is. Even though the turbine wheel is much larger, it still spools much faster. It is crazy what modern turbo technology can do to a 20 year old turbo design. Most people focus too much on the "compressor wheel" because that is what everyone can see, but the fact of the matter is 90% of the "turbo magic" comes from the turbine side of the turbo, and we did our due diligence to make this the best option on the market.
*Upgrading to an Banks Technicooler Intercooler is recommended and beneficial if you have, modified injectors.
