VTT is proud to announce our 2007-2020 6.7L Cummins Billet Valve Cover. We created these for the Cummins owner who wants to get rid of their crankcase filter, and plastic VC, while giving you a variety of ways to run your crankcase ventilation. The gas chamber comes with SSS mesh to knock down any oil droplets before it gets to the turbo inlet if you choose to run stock routing. You can also rotate the gas chamber 90 degrees, and run a hose down under the truck, or you can run this with our Billet catch can, for the ultimate in keeping oil out of your turbo inlet, and out of your Engine. This upgraded billet VC also adds some nice color, and pop to their Engine bay. These come in 3 colors Red, Black, and Clear, Anodize, as well as custom colors, are available (3-4 weeks for a customer color $200 upcharge)<br>
VTT Is proud to introduce the GC and GC+ line of turbochargers for the DAZA, and DNWA 2.5L AudiEngines.<br><br>These units are a white sheet design based around the factory turbocharger footprint while removing all the factory restrictions left when people stuff larger wheels into factory housings., AKA “Hybrid” These turbos are priced outright meaning no core charges. Keep your factory turbo in case you ever need to go back to stock, sell it to recoup some of your investment, etc. This also means no downtime, once we have the units on the shelf, you order -> We ship…<br><br>We start with our investment cast 310SS turbine housing/manifold with improved runner design for better velocity and flow. We couple this with a turbine housing AR increase from .65 on the OE housing to .85 on the VTT housing this will allow much more flow before reaching the backpressure limit while keeping good response. Following the factory footprint allows any existing downpipes on the market for factory turbo to be retained.<br><br>Next is the Compressor housing. Custom cast with the factory footprint but we do away with the 2 bolt inlet, and have a simplified 3” barbed inlet coupled with our 3-4” reinforced silicone turbo inlet that will mate with any 4” inlet on the market. Following the factory footprint also allows the turbo to accept our silicone reinforced charge pipes or any already available hot side charge pipe options. Boost control options are 1. Reusing the factory vacuum actuator or 2. Upgrading to a boost controlled model will be available (requires tuning changes)<br><br>Next is the CHRA, which is custom cast around the stock turbo footprint and designed to accept our wheel designs, as well as updated internals with a more robust thrust bearing over the stock design. Following the factory, footprint allows all factory lines to be reused, with no need for additional lines or adapters. True plug, and play. These are Journal Bearing units.<br><br><strong>Wheel sizes are as follows:</strong><br>
VTT is proud to offer billet wheel spacers for most VAG, BMW, and the A90/91 Toyota Supra platforms. These spacers are CNC machined from 6061-T6 aluminum and hard anodized black for long corrosion-free life. We offer them in the below sizes, which fit many platforms including but not excluded to BMW G8X M3/4, G Series 2/340i, A90/91 Supra, Audi RS3 8V, Audi TTRS 8S, MK7 MQB VW GTI, Golf R, Audi A3, S3, B5 Audi, BMW E/F Series 335, 135, F8X M3/4. Prices vary from $15.99 for a 5mm spacer to $23.99 for a 20m spacer.<ul><li>5×112/5×100 57.1 Bore for many VAG applications – 5mm, 10mm, 15mm, 17.5mm, and 20mm</li><li>5×112/5×100 66.6 Bore for New BMW’s, and MK5 Toyota Supra – 5mm, 10mm, 15mm, 17.5mm, and 20mm</li><li>5×120 72.6 Bore for most pre 5×112 BMW applications – 5mm, 10mm, 15mm, 17.5mm, and 20mm</li></ul>These are sold individually, for one axle order and two for a complete set order of four.<br><br>Anything over 5mm will require longer bolts or studs, you can choose to add a VTT wheel stud kit from the options.<br>
VTT is proud to offer the only complete N54, N55, S55 complete crank hub solution that does NOT require the crank to be drilled for pins. Our hub uses our proprietary “Spline Lock” technology that uses high tolerance machined splines which press into the crank, and positively lock the hub to the crank. The splines are machined in such a way that rotational forces drive the hub, and splines deeper into the crank meaning when the hub encounters a situation that would normally slip a stock hub the splined hub is driven into the crank to keep it in place (much like a splined extractor). We spent many months testing, and retesting this design, utilizing well over 10 different samples to come to our final production version. During testing, our final hub managed to break our testing rig before slipping. These have been bench tested, and real-world tested on the VTT N54 race car spinning 8K RPM, and making well over 900WHP. This technology means our hub installs the same as a stock hub, with no drilling of the crank, which means MUCH less labor is involved and is reversible if ever wanting to be uninstalled leaving no holes in the crank. The “Spline Lock” is ONLY available with the VTT Crank bolt capture for the ULTIMATE Crank Hub solution for your BMW. These parts are designed to be used together, and the spline lock should not run without the CBC.<br><br>VTT “Spline Lock” Crank hubs are CNC manufactured from 440C tool Steel with a Rockwell rating of HRC60 for the ultimate in durability, and toughness.<br><br>We suggest the Crank Hub System ONLY be installed by a qualified shop or technician. Timing tools are 100% REQUIRED if installed improperlyEngine damage may occur.<br>
