yes the supercharger is there for sure but we cant see if theres a turbo. Im going to say probably not. It is a lot of bends for a header

 

Way too many bends. With bends come losses and with that many bends, your talkin detrimental to your exhaust flow! But if it is turbocharged, equal length is more important than the losses that'll come with the extra bends so maybe...it does look extremely well made though

 

Looks a lot like the header my Fiat is going to have going on it once I finish building the engine.



And honestly, if you look at some race cars, they have convoluted headers too, especially the F1 cars

 

you have a fiat??

Which one?

damn dude, I cant wait to come down now lmao.gif

I want an Uno IE turbo.. 1.1 litre turbocharged.. Easy to get them to about 180bhp and theyre no bigger than a mini and weigh about the same as a jam sandwich lmao.gif

 

yeah really mad.

take a look at some f1 exhaust manifolds. bends mean nothing provided they are smooth.

 

I guess i should have explained myself a little better. WELL designed bends can overcome a majority of losses but bends ALWAYS incur losses. Some bends are helpful to promote backpressure, some are there to keep flows subsonic. This is a little exerpt from my Fluid Dynamics book (I'm an engineering major give me a break)

"Bends are an integral part of any pipeline transport processes, and the flow patterns developed are more complex than those of straight tubes. Fluid motion in a bend is not parallel to the curved axis of the bend. As the flow enters into the bend, the centrifugal force acts outward from the center of curvature on the fluid particles. The slower moving fluid particles move along paths whose radii of curvatures are smaller than those of the faster moving particles. This leads to the onset of secondary flow such that fluid nearer the wall moves toward the inner wall while fluid far from it flows to the outer wall."

Basically bends send the exhaust particles into each other except straight out of the pipe which will slow down velocity, but again WELL designed bends can overcome most of that. Sorry about the rant, just that i have the books right in front of my on account that i'm studying all the time nowadays...

 

What kind of car is that? Also, just a little side question is equal length bad (used losely) with supercharger setup or an NA setup?

 

it's probably out of a golf or a jetta.. as for equal length. the only thing better than equal length (in all circumstances) is tuned length, where each runner is tuned to help scavange the adjacent cylinders of their exhaust gases.

 

Looks like a Chinese knot...a big shiny one.

 

Exactly, tuned length is ideal but very time and cost draining. Equal length is second best but almost as good because theoretically all of the exhaust gas should reach the same spot at the same time. Now does that happen, not exactly but usually its no too far off.
