BOV for the Jim Wolf Technology TT kit


Owners of the Jim Wolf Technology 350Z/G35 Twin Turbo Kit find themselves in possession of what is arguably the best turbo kit on the market today. With its useable power band and unnoticeable turbo lag, the twin Garrett Sport/JWT -530BB Dual Ceramic Ball-bearing Turbochargers make for one fantastic upgrade. The kit includes two Cast Manifolds, two Ball-bearing Turbochargers, FMU, Fuel Pump, Spark Timing Control Module, JWT Pop Charger type intake w/ heat shield, Oil Pan Spacer with Oil Return Line Kit, Washer Fluid Relocation Kit, Coolant Kit, Intercooler/Charge-pipe Kit, and all necessary hardware for a complete install. The JWT kit utilizes a BOSCH recirculating valve that although extremely efficient leaves something to be desired by some turbo owners, the benefits of the sound produced by an atmospheric Blow Off Valve.
Owners of the JWT were not left with many options when it came satisfying their aural desires. Other companies offer various other recirculating valves none of which produce a noticeable improvement in both boost stability and sound. Replacing a bypass valve with a push type blow off valve leads to stalling and idling issues with the JWTs draw thru MAF set-up. The car would sound nice but consistent compressor surge and stalling led us to believe there was truly no benefit to this upgrade. If you were unaware of these issues and welded a flange in addition to closing the stock recirc ports you were in for some big time issues. After many customer and vendor demands the designers at Relentless Autosports sought out to tackle this issue. Because of their great reputation in the industry, Relentless Autosports sought out the help of GTSPEC to help design and implament this JWT TT BOV conversion kit.

Relentless Autosports along with GTSPEC went to work designing a BOV kit for JWT TT customers that not only performed well, but exceeded their strict goals for quality and craftsmanship. For this reason they turned to HKS to be the focus of their system. The SSQV utilizes a pull type system that not only stays shut under boost but also doesnt open under partial throttle, which can create rich conditions that lead to stalling. By designing a truly bolt-on system we were able to eliminate the need to spend money having the stock JWT system converted to accept the SSQV. Using a purpose designed cast flange, OEM port plugs, SAMCO Sport hosing, and other necessary hardware, Relentless Autosports created and GTSPEC implemented a fully functional BOV conversion kit that allows JWT TT owners the benefits of HKS SSQV BOV in an easily reversible kit that has no stalling or idling issues. No retuning of the factory ECU or supplied Split Second box are necessary for this upgrade. It is a truly bolt-on application that will eliminate boost creep, fluctuating idle and the desire to hear an atmospheric Blow Off Valve.
