Not satisfied with simply holding the stock turbo 1.4T world record with 196WHP and 259WTQ (race fuel, minor bolt ons, BNR Tune), we've been tinkering for a while on a bigger wheel turbo upgrade.

Starting with a brand new core from GM, we machine out the compressor housing to accept our all new billet wheel, featuring the latest aero technologies and laser balanced to 200,000RPM. Initial testing has yielded just over 200WHP on 91 octane fuel. We estimate 220-230WHP or more capable from E85 or race fuel, but have not finalized testing on different fuels yet.

Look for this upgrade to be available in the next couple of weeks :)

This sounds awesome! Would we have to upgrade any internals? I would also imagine we would need to re-tune.

It's not the same. Our wheel is completely different, and different size than vtuner's. Plus we are using only brand new turbocharger cores, not used/rebuilt.

will be adding this to my list of future engine mods, along with the flex fuel kit! I will be watching for more details on this.

what kind of torque numbers were you hitting when you passed 200hp?

Weather has been stopping us from finalizing everything on the dyno. As soon as the weather lets up we will be back at it and finish up. Stupid snow.

There will always be a core deposit. Doesn't make sense to send someone a brand new turbo, and not cover yourself, if you need a core back. Unless this is just a full price turbo, no core required. Because he did say that these were factory fresh turbos.

No cores. Factory brand new turbochargers with the upgrade performed is how they'll be sold.

These are basically ready to go as far as the turbocharger development is considered. We're working now on using a new injector for better spray pattern and to be able to push E85 with this turbo. The green 42s are at 80% on 91 octane. We did make 201WHP/250WTQ on 91 with this turbo, at a mild 21psi.
