Project hopefully kicking off in Autumn. Final go ahead within a month or so.

Smooth n/a style with a nice bump at 3.5k. Lots of boost for low numbers. Small cc engine?

Are you hapoy to share build spec, boost curve/ piping, dyno and broad mapping strategies? An expert builder and expert mapper will be doing all this but I want to know as much as my little brain can handke as I am driving the project to be and funding of course. Only this am came across garage...

Adjacent = parallel setup? 5+32+14.7=51.7/14.7=3.5 is pressure ratio? Or 2.5 bar, correct?

Compressor and adding minimal pipework and wastegates is not complicated (for my mechanic) 3. Getting transitional mapping prob very doable by reputable mappers but is a sticky but solvable concern. 4. Substantial torque increase below full spool and dropping full spool threshhold say 750-1000...

Haha. Like I need a (logical) reason... 1. The dropoff of torque (not power) frustrates me a bit. No different from ringing out say a k20 honda, most bike engines. 2. Losing the a/c comoressor

Thanks yldo :) recently dug up a few subaru wrxs with twin screw and centrifugals but critical info re piping and boost management lacking. I will do a full write up if/ when I get there.

Looking to combine rotrex and turbo [theory only atm] with siamesed intercooler intakes running simultaneously and not feeding into each other [?avoiding retrograde flow with valves]. I imagine flow is added from each but is pressure also added together i.e. at 'x rpm' if turbo is making 10 psi...

Norris designs has a twin charged tvs [iirc] + turbo [mitsubishi evo] . sc cuts out like a/c once turbo is on. kit is available @ ? 7-8 k gbp.

Joined today. Into forced induction and awd and now want to be twin-charging [an evo].
