Turbonetics Turbo and Spearco Intercooler - Sohc On This Part 5

This is the fifth installment to our War Wagon build up. The infamous Bisi Ezerioha of Bisimoto has set track records with his drag SOHC Honda engines. Off the strip, he's set out to build the most badass five-door hatchback you will ever see. His goal, 700whp on a street-driven SOHC 1.6L engine. This month we break the engine in and do a trial dyno run on low amounts of boost.

After all the engine plumbing was done, in went the radiator cooling fluids and Torco TBO 40 Premium break-in oil. Torco TBO is recommended to be run for 30 minutes or longer on new or rebuilt engines for racing, high performance or street applications; extremely good for running in engines prior to switching to synthetic-based motor oils. The Torco Break-in Oil is a blend of hydro-processed petroleum base stocks that clean and prepare new surfaces in the Bisimoto Engineering D16Z6 engine. Since the first start up of a new engine is critical to its life expectancy, TBO utilizes specially selected additives in order to protect vital engine parts during the first startup. TBO cleansing agents "scrub down" any contaminants left in new engines from the build process and assure good cleansing of the freshly-machined parts. Using protective anti-wear chemistry allowed mating surfaces to gently make contact during the first new startup of the Wagon.

Torco TBO provides the proper film for new bearing protection and is made to withstand viscosity breakdown in order to maintain an amazing hydrodynamic wedge. Torco TBO contains a high percentage of zinc anti-wear chemistry for proper valvetrain and new Bisimoto 3.6 cam break-in protection. I have used the TBO exclusively in all my builds, and the oil drains so dirty after the first dyno session, or so. Works impeccably well with less than a 2% ring leakdown after less than one hour. I was very skeptical at first, a few years ago when I experimented with it, but to my chagrin, it works extremely well.

After the break-in on the Dynapack dynamometer, we drained the dirty break-in oil, and filled up with Torco SR-1 Racing 10w-40 synthetic oil. A nice advantage of using the Dynapack dyno, is the keen advantage of having access to the "set speed" function: this allows a dyno operator to break in street and race engines by setting a predetermined RPM target, and varying the throttle accordingly. This also allows for impeccable tuning of partial throttle environments for the ultimate in drivability. Based on the power levels we anticipate, we also opted to upgrade the factory axles to a beefy set from Insane Shafts.

With some tuning on my part using the new AEM tuner software and the Series 2 AEM EMS, we were able to extract an amazing 389.9 whp and 255.3 wtq at the Turbonetics RG-45 wastegate pressure of 13 psi. With numbers like this at low boost, on unleaded pump fuel, without the activation of the AEM water-meth kit, we are in for a great ride and the possibility of exceeding our power goals! This example is a true testament of the reliable power that can be realized, if you choose the right parts for your build. With peak torque hovering in the 7400rpm range, and the horsepower at 8500rpm and still climbing, the Bisimoto Level 3.6 camshaft was performing its designed duty.
