A Tial wastegate earns its keep controlling the pressure generated by the free-wheeling turbo.
Pressurization is generated by an Extreme Motorsports-spec Garrett hybrid turbo charger. The turbo sports secret spec'd housing A/Rs and wheel trims and is a key factor in the Diamond Star's speed. The intake charge is chilled by a front-mounted air-to-air intercooler prior to entering the turbo system's 3-inch intercooler ducting. When the car is really hooked up a Nitrous Express single-nozzle wet manifold nitrous system is squeezed into play from the line to the traps. The system is configured to add 100 horsepower to the party-that'll get it done.

A Mike Hansen manifold is home to a Garrett turbo configured to Extreme Morotsports' secret specs. The turbo system consists of a Tial wastegate, GReddy blow-off valve and an Extreme Motorsports XBC boost controller. Max pressure is 30 psi.
On the fuel enrichment side we find an interesting mix of components. The fuel system utilizes two high-flow Bosch pumps that feed eight 550cc injectors which are driven by a Haltech E6S-8 engine management system. An Essex regulator controls the flow of race gas to a custom Extreme Motorsports fuel rail. Air is introduced to the combustion chamber by four individual throttle bodies, spark is zapped in by a single-coil-per-cylinder Extreme Motorsports ignition system where Magnecor wires and NGK plugs light off the mixture of C-16 and boost. Sean has gotten a lot of mileage out of his motor but still has a few tweaks in store for the powerplant during the cold Maryland winter.
Getting the power to the pavement is key but an all-wheel-drive car poses some unique challenges. If you do too good of a job, you'll break axles, transfer cases, transmissions etc. Koni coilovers that utilize Eibach ERS springs dictate the transfer of weight while a factory front sway bar and Suspension Techniques rear sway bar increase stability. The Talon claws at the track via M&H slicks. Sean runs 24.5x8.5x15 gumballs on Bogart Racing Dragonfly Star wheels. After tripping the lights in a tick under 150 mph the Diamond Star is brought to a halt with the stock braking system which has been enhanced with Power Stop rotors, Axxis Metal Master pads and stainless-steel brake lines (and a parachute if necessary).

The interior is all race with a 10-point NHRA-certified roll cage from Autofab Race Cars providing protection and adding to the car's rigidity. Piloting the 9-second screamer is an all Sparco affair-Sean is strapped into a Sparco racing bucket seat and guides the Talon down the track via a trick Sparco steering wheel. Instrumentation is handled by Auto Meter Phantom Series gauges while a Phoenix Fire Suppression System is on call to extinguish any flames should things go awry.
