Test 3: New cast AGP manifold (ported) and New Garrett turbine housing (ported)
Results showed that the First pull was the ‘best’ in terms of power with the consecutive runs showing heat soak again. The EGT probe’s tip actually broke off during the first run of this test but thankfully there was no turbine damage done.

Temp readings for surface were NA/360/365 and NA/190/220 at 2” ambient.
Overall results: showed improvements (quicker) in spool by ~75rpms, and with the exception of one small blip at ~3600rpm showed improvements in torque across the entire rpm range up to
36ftlbs more (average of ~15tq more in the midrange and ~7wtq above 5500) and power across the entire rpm range up to
25whp more (average of ~11hp more all the way to 6,000rpm) when compared to the baseline run.
