Drop-in turbocharger technology is evolving quickly. The 2nd Generation of Stealth Technology allows your LB7 to get up to 640 HP!
It’s still a direct drop-in, bolt-on stock appearing replacement but with features you won’t find anywhere else. The G2 improves power, towing potential and overall performance though the use of a custom designed high flow turbine assembly and 7075 billet compressor wheel. We do all this in a liquid cooled package protected by 360 degree thrust bearings.
The larger turbine assembly allows for lower drive pressure, creating a better balance between boost and drive (exhaust backpressure). This improved balance under heavy load means more efficiency and power at a given boost number, resulting in lower EGTs under heavy load. Overall peak power is also improved, where the Stealth 64 G1 would normally support 600-610 HP, the G2 now pushes the envelope to 640HP. You’re not going to find all of these features anywhere else in the aftermarket in a truly stock appearing, bolt-in IHI turbocharger.
G2 technology takes our Stealth 64 and improves every element of it – including the sound.
The G2 is designed to take the stock long block LB7 as far as possible with stock connecting rods – that’s up to 640 rear wheel horsepower.
To set a strong forward trajectory on our turbo program we’ve aggressively brought as much of the development and build processes in house. Our machinists and builders are enthusiasts who are empowered to look for and actively pursue improvements in design, to hone the product quality at every point in the process.
On the Stealth 64 G2 that means improved tolerances and attention to compressor wheel design. It means sectioning several exhaust housings to ensure consistency in exhaust housing scroll and exducer profile improvements.
Every charger is inspected and QC’d before it ships and backed by our Duramaxtuner warranty.
The Stealth 64 has been on the market since 2013. The G2 represents everything we’ve learned – coupled with our in-house manufacturing and quality control – to bring the Stealth 64 to the next level.
