OK, here is a really easy question but I need to ask it. On a turbocharger, the performance gain is from the intake boost generated. Not the turbo speeding up the exhaust. One of my friends says that most turbo generate no boost but instead have only one turbine in the exhaust to speed up the exhaust????
Please I need some proof, plus if I'm wrong I need to be corrected.

Thanks, Garrett

 

You are correct. The gain comes from the extra air stuffed into the intake. The turbo actually add backpressure to the exhaust, so its not speeding up the exhaust flow.

 

A blower is basically a fan that is run off the belts on the motor to cram in more air. A Turbocharger does the same exact thing but instead of getting power from the belts it uses the exhaust gasses to turn a turbine that forces more air into the motor. (I don't think I explained that very well) I would just let your friend think what he wants and then wonder why he always looses.

Hell most of my friends think HP = torque*RPM/redline. I tried to explain it but they don't understand

Yup, slap your friend on the head!! Hahahha j/j, but like Greasemonkey said, the power comes from the air being sucked/rammed into the intake.

Think of it this way. Right next to the engine you have a turbine. Air comes through the airfilter, is passed over the top 1/2 of the turbine, and goes into the intake manifold of the engine. Then the engine does its thing and the exhaust gasses are released. As the exhaust gasses come out of the exhaust manifold, instead of just being released through the exhaust, they are routed up to the bottom 1/2 of the turbine. The gasses spin the bottom end of the turbine and are then released through the exhaust.

Now back to the intake. As the turbine spins (from the exhaust gasses), it builds pressure at the top 1/2 connected to the intake. The pressure causes the intake to suck more air in through the air filter... thus ramming more air into the engine. The more air being sucked/rammed in, the more air going out the bottom turning that turbine .. and it just compounds itself.

Thats not how every turbo setup is designed (it gets even more complex than that!) but thats a good way to understand the concept.

 

Your friend is stupid and deserves to drive a Honda with a big aluminum wing and stock hubcaps.

You are correct, the extra power comes from air being forced into the engine

 

Actually the guy does drive a Honda Civic ('01) I think, with a v-tec and a supercharger (Yea I said supercharger). But the really sad thing is, is that he has over 25K total in the car and I can still beat him with the top 6 of the 7 cars in my sig. And closer than you would think on the last one. And those cars all totaled aren't worth 25K.
But anyways, The Civic does have a huge wing on it as well as a set of gay 20" rims, ground effects, clear taillights, and stickers OH lord the stickers this kid has. BASIC RICE
Thanks for your help, Garrett
