    A customer recently picked up an Eibach Pro-kit for his 2010 Mazda 6 and sent over a few before and after pictures from his Do-it-yourself Eibach Springs install. The Mazda 6 lowering springs from Eibach are roughly a 1.25″ drop and come with a million mile warranty.

    The automatic L99 arrived at the STILLEN Performance Shop with a Camaro SS Magnaflow Cat-back exhaust system already installed. We quickly put it on the dyno to get some base numbers before the Camaro dyno tune. Numbers came back at roughly 345HP and 348TQ, a slight increase over a bone stock L99.

    Cold Air Inductions – Camaro Cold Air Intake Kit

    Along with a few other exhaust modifications, we added a Cold Air Inductions intake kit (#CAI501109910). These US made Camaro intake kits are ceramic coated inside and outside of the tube, and also include a thermal insulated air box to keep the incoming air as cool as possible. Cold Air Induction also specifically designs and engineers their own air filters to maximize performance.

    One of the first Whipple Superchargers came through the STILLEN Performance Shop recently. With our newly signed agreement, STILLEN is now the only recognized and warranty certified installer in the Southern California area for all Whipple Superchargers. We were excited to get right to it and install one of these amazing pieces of machinery on a 2011 Chevy Camaro SS Convertible.

    The Camaro SS has been a regular in the shop as of late, but this is one of the first convertibles. Although this was a fairly stock automatic L99 and already on a lower power range compared to it’s 6-speed LS3 brother, we were still hoping to see a significant power increase once the Whipple Supercharger was bolted on.

    Whipple Supercharger Twin Screw Technology

    Whipple Superchargers have been leading the way of GM twin-screw supercharging for over 23 years and have engineered the most powerful intercooled twin-screw supercharger system available today for the Chevrolet Camaro.

    With the latest technology, the all new Whipple supercharger system creates more power than any other positive displacement forced induction system on the market and is 100% complete and designed for stock engines, but also has enough capability to work with heaviest of modified engines

    Putting the newly installed Whipple Supercharger on the dyno, we had some of the highest numbers we have ever seen come out of the L99 – 483.75 HP and 448.52 TQ! That’s an increase of 146 HP and 112 TQ over the stock motor.
