A few members have asked about short stacks. I started making stacks for SP1 and SP2 of the same length (+/- 48mm). I have never seen evidence that two short stacks give a significant (!) increase in top end power. However on RC51.org Mike did back-to-back runs with 2 short stacks and found no increase on top and a loss of midrange... So I decided to go for a compromise: SP1 oem stacks are 35 and 65mm (48 is about halfway) and for the SP2 the longest oem stack is 45mm and mine are e few mm longer but the SP2 already has the bigger throttle bodies for top end power... So I went for what should give a good spread of power on both SP1 and SP2.
