I was out of the country on business, and just returned this week. After the break-in with the Torco TBO on our Dynapack dynamometer, we drained the dirty break-in oil, and filled up with Torco SR-1 Racing 10w-40 synthetic oil.
The TBO did an excellent job in scrubbing contaminants from the freshly built engine. Below is a picture of the Golden Eagle drain magnet after the break-in period.
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: a huge advantage over inertia-style roller dynos.
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 8500 and still climbing, the Bisimoto level 3.6 camshaft was performing its designed duty.
I have some many items to attend to since my return to the US. I will try my best to come back soon and share some mid boost level runs, and share some of the issues we experienced with higher boost levels...and how we solved them.
