Sorry Cambo, I only just at last figured out that he has no idea that WE THE PEOPLE elect our government.

???j-complete??j-complete????Was looking for something else & happened to see this. Figured I'd leave it here in case somebody was interested in following up on it. Check a little more than halfway down the page...

this kid is 20years old , he started welding at 16 in high school shop, Austin Texas.

now moved on to a high tech engine lab. doing all types of fabrication and welding.

i'm always impressed with skills that become art.

these turbo headers are for a Nissan GTR, making them fit to the car was amazing!

Work of art to be sure.

But, I have always wondered, what is the right balance of exhaust pulse arrangement vs a torturous convolution of tubing.

All of those twists and turns come at a loss of momentum, so what is the right balance to maximize flow?

.

so true, but to make them fit the vehicle, a street car new only 1 month old, without destroying the body and 4 wheel drive system, you make some sacrifices!

they wanted larger turbo's and a SS header/exhaust system, along with engine mods, car made 850hp on 1st dyno pull. factory displacement!

since then,about 1 year ago, it is up around 1000hp ,and cruises around Austin TX.

ccfulton, to add to, this forced induction system engine is turbocharged not supercharged!

a basic turbo needs to simply turn the turbine wheel that will inturn spin the compressor.

think what it takes to spin the turbine, you need combustion exhaust gases, how you deliver them can get tricky, pipes that connect from engine to the turbine housing(the housing is a very complicated part), looks simple but aint.

you need gases to enter in volume, velocity,and pressure, one a lot of guys miss is you need heat most importantly, along with exhaust pulses!

but the real world is just not gonna make all those requirements doable on a street car,packaging becomes a problem!

so we sacrifice some of them, or modify to the most logical method.

so often exh. pulses is 1st to go, because the wheel would prefer a smooth flow,not hard hits of pulse

but you can have large chambers of piping, not straight but plenty of volume(inter turbo lag).

and housing if properly sized, can have the a small size nozzle that alters flow , but increases pressure, against the wheel.

then you have the heat(odd you want a lot of heat?), yes as the flow goes in hot it starts to expand, increasing velocity.

all together they spin the turbine at phenominel speeds, and the compressor pumps air to make a pressure in the inlet manifold!

modern turbo systems have made them practical ,and one mod that really upped the effect of a street car is the variable geometry unit, good for boost down low and good boost up high!

and intercoolers are more effective today, and we will see water or alcohol injection getting hi-tech also, all this hi pressure in the inlet can make heat which you dont want on the cold side!

simple right,LOL, anyway a quick view of turbos , some theories may not be exactly 100% correct, but if you indulge into them you will learn a lot from net.

couple pix,, Mazda rotary(i work on anything thats interesting) big scoop under car, 500hp from 1.3 liter,.
and a 1400hp in/line 6 cylinder Toyota, 204mph 6.7 seconds, 1/4 mile.

turbos work just fine!
