Just kinda curious about the manifold… So the way I see it (probably wrong) is that 3 cylinders will be firing at a time while the exhaust gases spin the turbine, not obviously a twin scroll would solve the problem I am going to bring up, but are all the tubes equal length? If they aren’t, wouldn’t this cause some sort of backspin or irregular turbo spool?

Again, just curious for my own knowledge.

for the manifold its not a twin scroll but, im no fluid dynamics expert. there is no sign of compressor surge and the runners are fairly close to equal legnth, except cylinders 5-6 which are shortened to allow for a 3" downpipe.
