    2017 Chevrolet SS – Whipple 2.9L

    On this installment of Whipple Wednesday, Jesse brought us his 2017 Chevrolet SS to create the perfect American family sedan, injected with a little bit of Aussie spirit! Following the desired Holden HSV GTS setup that we never got stateside, this SS features something the SS’s should’ve come with in America……BOOST!

    With the added power under the hood, Jesse can fully immerse himself in not only the vicious growl of the LS3 6.2L V8, but also the sweet sweet whine of the Whipple 2.9L W175FF supercharger system, all the while manually shifting all six gears though the Tremec Transmissions TR6060, fully creating an intoxicating experience that Jesse will be sure to enjoy.

  • 2017 Corvette Grand Sport – A&A Supercharger

    2017 Corvette Grand Sport – A&A Supercharger

    Over 550whp on tap, and sporting a new form of fun hidden under the skinny pedal, Don’s 2017 Chevrolet Corvette Grand Sport is one killer daily driver. While the LT1 is a great performance engine in its own right, Don desired more, so a plan was implemented to add something most every C7 owner wants under the hood…..BOOST!
     
    Modifications performed by us:
     
    • A&A Corvette Performance supercharger system
    • Vortech Superchargers polished V3 Si head unit
    • A&A Corvette Performance 8-rib 3.80″ upper supercharger pulley

With 93 octane in the tank, and the Vortech YSi delivering ~9psi, Vlad increased the LT1’s output to a solid 571.37whp & 554.79lbft! Some pretty outstanding numbers considering this C7 is still on the stock fuel system!

  • 2019 Honda Civic Type-R

    2019 Honda Civic Type-R

    The newest generation of Honda’s Civic Type-R boasts some obtuse styling, something that can be hard for some to handle, but hop in the driver’s seat of one of these and you will find out just how much fun Honda’s latest iteration of the Type-R lineup is to drive. Featuring great performance and practicality, this hot hatch seemed to tick all the boxes for its owner Rueben.
    With the helical limited-slip differential keeping both front wheels under control, an extremely rigid chassis, joyous 6-speed manual transmission, and Honda’s known reliability completing the whole package, the FK8 CTR’s are considered one of the best-performing cars in the front-wheel-drive market today, consistently receiving positive praise from journalists, owners, and enthusiasts alike.
    While good enough for most, Ruben wanted to enhance his FK8, so a decision was made to bring us his bone-stock 2019 Honda Civic Type-R to get the K20C1 breathing a bit better and making some more jam! Modifications performed below:
     
    • PRL Motorsports, LLC air-intake system
    • Mishimoto Automotive stock-location upgraded intercooler
     
    With the mechanical work wrapped up by Andrew in the shop, Matt strapped her down to the rollers for Vlad to get the FK8 dialed in via Hondata‘s FlashPro. With the stock turbocharger delivering ~23psi, Vlad increased the K20C1’s output to 333.43whp & 320.60lbft on 93 octane! Considering these cars normally baseline between 280-290whp in stock form, that’s a difference Ruben will definitely notice!

  • 2019 Chevrolet Corvette Grand Sport

    2019 Chevrolet Corvette Grand Sport

    Rick’s 2019 Chevrolet Corvette Grand Sport, finished in a fitting Sebring Orange Tintcoat, comes out of the box as a great platform, sporting loads of performance straight from the factory. With plans to track the car on road courses, Rick wanted more. The objective for the C7 was simple: increase throttle response, allow the engine to breathe better, and increase power. With a plan in place, the car was pulled into the shop and the build commenced. Build list below:
    Pre-existing modifications:
    • aFe POWER air-intake system
    • CORSA Performance cat-back exhaust system
    Performed by us:
    • MSD Performance Atomic intake manifold
    • Katech drive-by-wire 103mm throttle body
    • Kooks Headers and Exhaust 1.78″ primary OD long-tube headers
    • Kooks Headers and Exhaust 3″ X-pipe w/ high-flow catalytic converters
    • MSD Performance spark plug wires
    • Design Engineering, Inc. Protect-A-Boot sleeves
    With the mechanical work wrapped up in the shop by Andrew, Matt strapped the C7 down onto the rollers for a custom calibration by Vlad via HP Tuners. With 93 octane in the tank, Vlad increased the LT1’s output to a solid 449.15whp & 455.32lbft, sending power to the rear wheels through an 8-speed automatic transmission. With the upgraded dry-sump lubrication system in the Grand Sport models keeping the oil pumped into the engine during sustained cornering and the added width of the fenders and body in contrast to the base model, you can say that Rick made a great choice when choosing the Grand Sport as a weekend cruiser and track car.

  • PCM Unlock Service – 2015+ Mopar Vehicles

    PCM Unlock Service – 2015+ Mopar Vehicles

    PCM Unlock – 2015+ Mopar vehicles

    National Speed offers PCM (Powertrain Control Module) unlocking services for 2015+ Mopar (Chrysler, Dodge, Jeep, and Ram) vehicles. Recalibrating or tuning a Mopar PCM involves physical modifications to the module to unlock the potential. This service is needed when tuning a vehicle to compensate for modifications, resulting in added power, torque, and performance. What does this mean to you? Fast Service! In the past, unlocking services meant sending your PCM directly HPTuners to unlock, getting the PCM sent back, and then tuning your vehicle in the shop. With shipping, waiting, shipping, and waiting…the process could take a week, sometimes more, to get a PCM back in the shop. Now that unlocking services can happen here in the shop, we cut out days of downtime and can get performance installations and tuning done faster. Tuning is necessary for any of our Staged Performance Packages and we have parts in stock to handle all Stage 1 and Stage 2 installs now… with no delays, backorders, or downtime.
