Recently we reintroduced our resident '01 Mustang GT-Project Icebox. The 8-year-old Two-Valve project car has seen many changes since its introduction, and has brought you the latest and best in Two-Valve technology. Last month, Blow-By Racing assembled an aluminum short-block with forged internals for the project. This month, we introduce the top-end components chosen for the build.

The focal point and key component of the new powerplant for Icebox is a 1.9L blower from Tork Tech. The twin-vortices series (TVS) is a positive-displacement supercharger, making it more effective at lower rpm than a centrifugal equivalent. "The benefit of positive displacement superchargers is the capability of low- to mid-range torque," said Charles Warner, president of Tork Tech and designer of this kit. The Tork Tech TVS promotes low-end power and torque by reaching full boost by about 1,700 rpm, thus reducing lag associated with centrifugal superchargers, according to Warner.

The Tork Tech TVS1900 supercharger kit (PN M46TVS1900) retails for $5,399. It comes with the TVS1900 supercharger; lower intake manifold with cooler; intake plenum with EGR adapter for the stock EGR tube; single-blade throttle body with linkage; intake tube; 8-rib independent-pulley drive system; front-mount heavy-duty heat exchanger with electric water pump, expansion tank, and hoses; and all hardware, fasteners, and hose clamps required for installation.

To complement the supercharger, we turned to Summit Racing for a pair of Trick Flow Specialties (TFS) heads, a pair of TFS cams to match, and everything else needed to assemble the top end. The TFS Twisted Wedge Track Heat 185 cylinder heads are available with either a 38cc (PN TFS-51910003-M38) or a 44cc (PN TFS-51900004-M44) chamber, and retail for $1,050.95 each. They include 185cc intake runners, 1.84-inch intake valves, 1.45-inch exhaust valves, and can handle up to 0.580-inch of lift.

The TFS camshafts feature 234/234 (intake/exhaust) degrees of duration, with 0.580-inch lift, and a lobe separation of 114 degrees. This profile is commonly called a "Stage 2" camshaft because it is the intermediate Two-Valve cam profile by Trick Flow. Because of its large lobe separation, this camshaft is a typical choice for supercharged applications, and should work well with our Tork Tech TVS. They retail for $479.95.

Summit Racing also sent us a set of TFS hydraulic lash adjusters (PN TFS-21400008-16, $149.95), a set of 16 TFS cam followers (PN TFS51800510, $14.95 each), a complete TFS timing chain set (PN 51800500, $329.95), a pair of TFS valve covers (PN TFS-51800802, $189.95), an FRPP head changing kit (PN FMS-M-6067-D46, $114.75), and a set of ARP head studs (PN ARP-156-4101, $241.64) to complete the job.

Next month, we'll be back at Blow-By Racing to assemble the new powerplant. We'll make sure our fuel system is sufficient, check the transmission and clutch, and install the new engine.

As always, we'll run it on the chassis dyno and take it to the dragstrip. Check back to see just how much power we can make with this potent Two-Valve.
