Just curious if something like this would work on the s, similar placement to the lovefab, but probably a hole lot stronger. Somewhat of a log, but the cylinders wouldnt be firing at each other.

Just picture a turbo flange on the end of this pic..

 

furthest thing from a long runner, and cylinders would still be firing at each other I'd imagine as exhaust gas waves traveled towards the exit the next cylinders could hit the wave dead on or worse right ahead making very high pressure zones. It'd have to be more complicated then this as the firing order and lag between would have to be considered, it certainly wouldn't be as good as equal length obviously but I think it'd end up being worse then a Log style since pressure build up would be exponential across the main tube.

Someone else could probably provide more accurate estimations on the results but I'd say...not good.

doesn't need to work that well when you start with a motor thats bigger then 2.0

 

Log manifolds like that can work pretty well, one the modern design aspects that is missing however in handmade manifolds I see like that is to include something called a "pulse converter."--Which is a narrowing of the runner right before it merges with the log. Lots of diesel engines use this. What this does is convert the compression waves that come out of other cylinders into a rarefaction wave that assists in scavenging in the cylinder--It doesn't have quite the same affect as a tuned equal length manifold. Due to the log area and the placement of each cylinder on the log the affect isn't the same for all cylinders either. It is a fair compromise between exhaust wave tuning, the energy available for the turbine and overall use of space however.
