The current intake manifold (right) fabricated for Irene next to the first one made and tested for the car. Even the “smaller” one is significantly larger than the stock piece. 
The intake manifold mounted with the Mustang throttle body. On the other end of the motor, exhaust gases escape through the URGE Designs Unicorn Header. URGE claims that this unit is the first and only header on the market that makes power across the entire powerband!
The header is then connected to a Berk Technology 3-inch header-back exhaust. For some minor weight savings, the sections of this exhaust are held together with Berk’s lightweight V-band clamps.
A photo from under the car shows the JRZ rear dampers, upgraded Evasive Motorsports differential cover, and Berk Technology 3-inch exhaust. Power is transferred to the wheels through a TODA 8 pound flywheel and a custom-made carbon-kevlar single disk clutch from Blacktrax.
After destroying a few stock rear differentials, the Blacktrax Performance team decided to upgrade the rear end with the best OEM solution available, so a Stage 4 unit was put together using an ATS carbon limited-slip differential by Puddymod, an S2000 forum rear end specialist. The final drive ratio was shortened to 4.44:1 from the stock 4.10:1. An Evasive Motorsports high capacity differential cover which holds twice the amount of fluid is on hand to keep fluid temperatures, and wear down. This rear end should be nearly bulletproof!
A look at the Evasive differential cover before going onto the car. Between the last installment of the Irene Makeover and now, JRZ Suspension Engineering released their 12 31 damper, which is their newest 3-way racing suspension with external reservoirs. The reservoirs allow the driver to control compression rates by being able to adjust the pressure in the dampers. The new suspension is tuned finer, with more adjustments available for both low and high-speed damping. According to JRZ,
“Every adjustment has an increased damping force range with finer adjustments engineered to enable the chassis tuner to make significant predictable changes every time.”
