Default Quadruple charged 4g63

Saw this thought it was pretty damn badass and well executed if not the most efficient or well thought out setup out there.

Are those GT12s? That looks pretty bad *** and remarkably simple for what it is.

would that mean instant throttle response AND big power? i can't see where the turbo's outlet's are connected. i see the one on the end hooked up, are the other ones just being blocked by the i/c pipe?

edit* okay i see the one on the opposite end and what looks like the center ones. where's that motor at, ams? i have a nice galant vr4 actually. over 400whp way faster than my miata straight line, but doesn't have the brakes for it's power/weight at the track. suspensions good, just need a rear sway to kill some corner exit understeer.

They all dump into the black plenum with the blue coupler on the end.

We've seen what Tim's two turbos can do, I just wonder how much exhaust can drive each one to spool. Otherwise if these are garrett's smallest GT1241, there's about 550BHP worth of turbo power at around 10psi. 14 lb/min * 4 = 56 lb/min

Um has no one noticed the T2 flange on the bottom of the exhaust manifold??? Does this thing have 5 turboes or is that for one big *** External wastegate.

That would have to be the WG because there are no WGs on the terboz.

An engineering marvel with limited technical value. Very well executed.

EDIT: More importantly, it is on a display rack next to the brochures in somebody's office building and not in a car. That also points to the intent of the build not being for actual use, but a demonstration of fabrication capability as pointed out above.

I want it for my miata with Vbands. For payment I can offer my first born child and all the labor you can get out of them for 18 years.
