A lot of factors play in slr numbers, IMO there is no "magic slr". Don't get to hung up on it its gonna want what it wants based on power numbers and where they occur. That little engine is likely going to want a fair amount MORE slr than the bigger armed one for sure. This is pretty much and apples to oranges deal honestly. I am sure the TQ numbers are significantly different in number and RPM. Id think that little engine would want to be over 11 for sure
