Get an Estimated Power Gain of Almost 20 HP in Your Z28 Camaro
- 14 Mar 2017
The Z/28 engine was adapted from the LS7 used in the C6 Corvette Z06, which was developed in conjunction with Corvette Racing. The LS7 is rated at 500 horsepower and 470 lb.-ft. of torque in the 2014 Camaro Z/28, with a maximum engine speed of 7,100 rpm. Chevrolet specifically developed the motor with a broad rpm range that contributes to higher power and which also allows the driver to hold gears longer between shifts on the track. That helps keep the engine operating within an optimal rpm range for quicker lap times. Each LS7 was hand-assembled at GM’s Performance Build Center based on the basic Gen IV V-8, but with a unique cylinder block casting with pressed-in steel cylinder liners to accommodate the engine’s 104.8 mm cylinder bores – and with processes you’d normally see only at a race engine shop – deck-plate boring and honing. The Z/28 is equipped with a dry-sump oiling system to ensure full lubrication during the 1.05 g cornering loads the monster Camaro can generate. Internally, 464 gram titanium connecting rods and lightweight intake valves boost horsepower by raising the engine’s operating range, as well as reduce engine mass. In addition, the LS7 is assembled with sodium-filled exhaust valves, aluminum pistons, forged steel mains, and a forged steel crankshaft. The LS7’s CNC-ported aluminum cylinder heads with straight runners were designed to maintain the fast airflow velocity demands of the engine’s 7.0L displacement, as it ingests more than 100 cubic feet more air per minute than the LS3 V-8 – a nearly 20-percent increase in airflow. One would think that the Chevrolet engineers had optimized every system of the LS7 motor, but there’s one where there’s still opportunity to increase performance. The K&N 69-4533TTK Typhoon air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit LS7-powered 2014 and 2015 Chevrolet Camaro Z28 models that has been proven to add nearly 20 horsepower to the monster Camaro.
The power increase is created by replacing the factory air filter and air intake housing with a K&N 69-4533TTK Typhoon air intake system, which significantly improves incoming air flow as well as reducing turbulence in the intake tube. The air intake first enters a carbon fiber capped K&N high-flow air filter sited within a ultra-lightweight carbon fiber heat shield that’s installed into the original air box space. A bulk of the horsepower increase can be credited to the oversized conical air filter manufactured from multiple layers of oiled cotton filter media -- which offers less resistance than traditional filters. The multi-layered cotton material also filters out microparticles that could damage your engine, to help ensure a long engine life. But before a filter goes into production, each design is verified through K&N’s in-house filtration testing lab. Testing adheres to ISO 5011 standards, ensuring that your K&N filter provides high airflow without putting engine protection at risk. Exiting the filter, intake air is directed through an aerodynamically-verified black powder-coated aluminum intake tube into the engine’s throttle body for nearly a 20 horsepower estimated gain. The intake tube includes fittings for the factory mass air sensor and crank case vent hose. Best of all, the K&N 69-4533TTK Typhoon air intake system can be installed in 90 minutes or less with simple hand tools. All tools required are listed in the clear, step-by-step photo-illustrated instructions specific to your Camaro that comes included in the package. And once you’ve installed your K&N Typhoon air intake system you’ve eliminated the need to buy another air filter for the life of your covered Z/28. The only maintenance is a service you can do yourself in no time at all. When it is time to clean the filter, use the K&N 99-5000 Recharger Kit to clean and refresh your air filter. The K&N air filter you purchase is designed to last for the lifetime of your vehicle, which K&N guarantees will perform for up to 10 years or 1,000,000 miles with the K&N 10-Year/Million Mile Limited Warranty. The K&N 69-4533TTK Typhoon air intake system is designed to fit the following vehicles: 2015 CHEVROLET CAMARO 7.0L V8 Fuel Injection - All Models | |||
