Ah, doing something overly complicated for the sake of doing something overly complicated. I like your style! Life isn't worth living unless you're pushing what you know and can do!
Taco's hopes and mostly dreams.

Although the diagram you made is different than most twin charged setups I've seen. Any particular reason?Comment

This gives a pretty good explanation of what can be done
We look at how to build a twincharger setup for your car and discuss the various twincharger configurations and their performance advantages with twin turbos, supercharger or one of each.
Im planning to run them in series where the boost is compounded, where the last diagram is ran inline where ideally you would want the supercharger to stop providing boost once out of its efficiency range.Comment

And for 2 why not place the Intercooler between the turbo and SC? The SC itself wont get as hot so it doesn't really need a postcooler. A lot of SC setups use preschoolers because the position of the SC relative to the intake manifold.
Edit: just curious! Always wanting to learnComment

Interested to see how you overcome the hurdles of twincharging. Ideal set up would be to have the supercharger over-driven to produce boost at idle. That boosted air should run non-intercooled straight into the intake of the turbo. This allows the turbo to be "pre-spooled" (i.e., limiting "lag"). After the supercharger can no longer push enough air into the turbo (maybe 12psi?), have a valve that opens up to atmosphere allowing the intake of the turbo to breathe freely (and supercharger's air can just dump somewhere else?) and continue producing boost on it's own. Then run your charged air through an intercooler into the intake of the engine.
I probably sound crazy (it's because I am). We have been toying around with the idea at the shop I work at for a while on our shop truck (can you say mid-engined compound cummins turbo diesel '49 ford?) Wait, WHAT?-Pierre

Superchargers tend to run quite hot at high rpm thus the loss in power in the higher rpm range as well as the parasitic loss. This is the way Denny runs his supercharger and he is seeing his air temps around 90 Degrees F if I remember correctly.
Im looking into My first setup idea right now, this also gives a wicked good explanation on more twin charging and why its setup a certain way. Its long but informative.

There is alot of possibility of what can be done, Im sure Ill go through a few ideas then change alot along the course of the build once the supercharger is in.Comment

We have a long way to go, but here's a teaser photo of where were at today. We will start running charge pipes this week. If you want to tag along we use hashtag #oldsmokeyf1 on instagram.
Oh and I'm definitely subscribing to this thread!-Pierre

FWIW though I wasn't talking about peak hp at all. The EFR series is known for excellent transient response and mid range torque as they were developed for road course racing.-Nick

Im looking into Kinugawas at the moment, they make some quite large turbos that would work well.

Bimmerheads cam and adjustable cam are were just ordered. Planning to port match the intake and exhaust manifolds for a bit better flow. Cant wait to slap this head together see what its like.Comment

Getting the turbo side done first then moving over to the supercharged side :)Comment
