Couple of things;
#1 if this is a tunnel port how is it using a tunnel wedge intake. Even though they both have "tunnel" in the name they are not the same nor are they interchangeable and the value could vary greatly.

#2 did I read right that this engine was built for NO2 and with 11 to 1 compression? I've never built an engine for NO2 but aren't the CRs normally lower like a supercharged engine?
