My Latest test data on the 58, using two tuned pipe header lengths on the MTW tuned pipe (the one for DA), a KS canister, and the MVVS canister setup.
The long header sets up the engine in the sweet spot, the short 300mm header makes for a finicky engine. Loads of power, but only with the right setup.
Edit:
I hope the picture explains all.
The MTW tuned pipe on the shorter 300mm header shows that the typical torque hump at 3/4 of best torque rpm enters the operating window of our props (5500 - 6500 rpm)
Not for me, but this tecnical stuff hurts my head. You Big Brain guys are great to have around but hard to understand sometimes.
You got three pipes x two header leinghs x testing for two things (torque & HP) = To me there should be 12 lines on your graph but I see 8.
How about a quick written conclusion?
I think for my DA50 its "buy the DA pipe, use a longer header"
