@45soldierboy I agree about the animation being nicely rendered but not about the direction the fan should be spinning. Each blade is cupped to be propelled "back wards"
@Yadilea on the hot side yes it is a good theory. on the cold side it wont work. also on the hot side the outer fins will have a larger chance to fatigue and break down. as an engineer i can tell you that this isnt practical nor cost efficient project and i quote "Each blade is cupped to be propelled "back wards". those this will "catch and hold a higher pressure and heat in the cast iron exhaust side. casing failure. if u wish to have an example i will be more than happy to show u.
If you want a easily modified car(for increased HP) that is much more likely to pass smog. Buy a car that has a turbo in it from the factory. If you live in california (unless you have connections) you will not pass smog with a turbo you put on your car aftermarket. A factory turbo car will have better engine management and stronger internals.
@cibaca1 turbos run between 100k to 140k maybe 150k like that one guy said but that must be a turbo on roids. 120k is a common rpm.
im not sure about the rpms of a diesel vs petrol but im guessing a diesel can take more boost bc diesels have stronger pistons, connecting rods, crankshaft ect
@a1u1s1t1e1n diesels run a lot more boost than gas engines. for a truck diesel, youll have over 20psi from the factory. and i know that big CAT diesels run ~60psi of boost.
@pepene93 lol diesel engines are the type of engine that are easiest to use a different fueltype in without almost changing anything to make it work well exept filters.
the way i look at it is that its basically helps the turbo spools quicker at a lower engine speeds then the other ones that dont have it, so basically you get a turbo with a mid range turbo to high range boost with out having sacrifice the low end for top end or top end for low end.
@jakenbake72 This is not a wastegate. A wastegate uses the same type of actuator but this is simply for allowing the turbocharger to work good in both high and low RPMs. So in this setup, there would be two of these types of actuators, one for the wastegate and one for the VNT.
That is incorrect. A wastegate relieves exhaust gasses before it reaches the turbine. This is made in order to make the turbo more efficient at certain RPM ranges.
@QuattroStig It would be the most efficient with as much exhaust gas as possible. The wastegate is just controlling the pressure of the gas going to the tubro (thus how much pressure turns the turbine = how many psi of boost are pushed through the turbo) a wastegate is just stopping over boost and controlling the amount of boost to the engine..
vnt ( i always called it V.G.T. for variable geometery turbo) is a fairly new idea, as much as i hate to say it Ford (bleh!) were the orignal designers of this technology. They put it on thier newer powerstroke diesles (especailly on the 7.3). and they did make a turbo laser daytona, but not a shadow, and dont forget the crystlar Konquest (2.6 liter turbo RWD) but none of those had VGT
nope, several volkswagen diesel engines have had this technology longer than the porsche 997 turbo... reason is, that the exhaust gases of diesels have a lower temperature (I think about 750-800°C). gasoline engines have a bit over 1000° - so they needed to update the material of which they are built, especially the vanes!
the small vanes are their for responsiveness. less mass to move (less exhaust gas flowing at idle/just off idle)
as revs increase, more exhaust gas has the ability to rotate the larger wheel. so the vanes open up. more air increases the velocity of the turbocharger, psinning the impeller on the intake side faster.
youtube isnt hte answer for everything. dont be keyboard warriors. find some tech articles and try and learn something for yourself
ugh, your close dude, not bad, what tose little "flaps" (their called vanes lol) do is create a venturi (think of a water hose nozzle that gets skinner and forces more water through a smaller space) that is adjustable which allows a higher velocitys of exhaust gas to overcome turbo lag at lower engine speeds and exhaust gas tempratures
the intake "impeller" is more commonly known as the compressor wheel, the exhaust side is the impeller wheel. but as far as explaining vgt your close, read my reply from above for a more "laymens" definition of vgt (Variable Geometery Turbo)
you think wrong lol very wrong, thats what a wastegate does, and every turbocharged system has one weather its internal or external. if you dont actually know what it is dont guess couse it makes you look stupid no offense but c'mon

when one of the moving flaps fall off bang goes the turbo and the engine.

how much RPM can a garret turbo achieve?
is there a difference between diesel and petrol engines of turbo rpms?
i have a polo tdi i i think i got this variable turbo.

it's a Wastegate.
sometimes the turbocharger spools to fast at higher RPM.
Speeds that the spline and bearings Couldn't handle.
And the wastegate relieves some of the air-flow to slow it down, as show above.
