Scion Release Series 5 - CNC Machined Head

However, running four LC1s, as efficient as they were, was still elaborate. We found a new solution in the LM2, also from Innovate. It is a clean, compact unit and we can mimic what we did with four LC1s with just two LM2s. It allows us to view air/fuel ratios in two cylinders in real time and has the capability of accepting more channels so we can have four O2 sensors go into this one box or we can monitor individual exhaust gas temperatures (EGTs), for example. We can also diagnose OBD2 diagnostic trouble codes if we want. It's very user-friendly and intuitive . We will use the LM2 system in our build along with my Bisimoto F22 header, and use this technology to monitor each exhaust primary AFR and definitely tune our engine to make sure that each cylinder has the proper air/fuel ratio for power and longevity. This "individual cylinder tuning" setup using the AEM EMS cylinder trim mapping function could possibly yield up to a 7-percent improvement in power over just having a global tuning map for the entire powerplant.

Our header is quite unique. It will have three steps on the primary, a Burns stainless 4-1 collector, and a venturi built in to the collector to allow us to increase the velocity of scavenging through the header itself, resulting in power. This is F1 technology, combined with our own meticulous dyno-based research, that we can provide to the street and race enthusiast.

Bad heat is the enemy of performance; Castrol knows that and we know that as well. Even though our engines are a chemical to heat to mechanical energy converters, we want to harness and utilize that heat properly. But that heat can also be our enemy because heating up our intake manifold can result in a dense mixture of air into the engine, limiting power production. We'll use a Bisimoto-Evolution heat-shielding gasket, a high-temp gasket that alienates the heat from the cylinder head from the intake manifold. The intake manifold stays cool, allowing a denser charge of air for the best power production. We have seen a 50-degree drop in intake degree temperature and a 5- to 6-horsepower gain on our Dynapack Dynamometer.

As I have mentioned before, the cylinder head has the highest potential for naturally-aspirated power. We've partnered with Portflow and Dasa Racing Heads to create a CNC-machined head, but we'll talk more about that next month and show you the final engine assembly as well as a new camshaft design that complements our Kinsler ITB manifold."

Classic Super Street
Our second year in production: By this time, outlandish body kits, motor swaps and fast drag cars are the big hits. Gran Turismo hits store shelves and our gaming lives change forever. Coilovers also begin to infiltrate the market, giving enthusiasts an all-in-one package to raise and lower their cars at will, albeit not very cheaply. A candy yellow Civic hatchback from Full Blown took center stage that month and Dave Shih continued to break fools off with his 10-second CRX.
