Turbo vs Supercharger

In Normal driving would it be your "opinion" your mpg would be better (no matter how slight) with a turbo charger vs a sc? I have a vw diesel and I gotta tell you I love my turbo charger as it seems easier to modify with parts already in place....

 

well thats the thing about a turbo compared to a sc. with a turbo you have to ride under boost. with a sc you are always boosting. but riding under boost get annoying when tryin to save gas. so in that section i give it to the sc. for power i give it to turbo. cause i mean once you have the sc. your kinda stuck with the mpgs you get. with turbo its a throw up.

 

You're not always in boost with a SC...

 

yeah but its always pulling tho. thats what i was saying.

 

so has anyone tested both on a tacoma?

 

I don't know if saying the turbo is as robbing of power as a s/c because it restricts exhaust flow is a valid argument because a turbine extracts most of its energy thermally. A turbo WOULD create a restriction in exhaust flow, but it would be insignificant compared to the increased rotating mass added by a s/c. A turbines rate of work output is a function of the change in temperature of the fluid flow. exhaust expands across the turbine, allowing the turbine to extract thermal energy. I'm just stating what I've recently learned in a thermodynamics class...

 

You sure are smart...I can't even spell thermodywhatmacallit....but it does my old bones good to see smart people are putting into english how alot of this stuff works....what surprises me--I understood everything you said and that's "scary!"

 

All i know.. blown seals in my turbo tacoma suck!

 

What turbo you running and how long did it last. What year Taco you got?

 

Like I already said, go ahead and change your pulley, but at a certain point your making enough heat that the extra boost does nothing good.

Not to mention your still very limited in the power your going to make, I can run 10 to 23psi efficiently, can you? No.


Like I said apples to oranges, SC if you want to bolt on a little kik and be done, turbo if you have skills and want to get far more power, but the SC is for most people since the parts are available and it bolts on in a few hours, turbo is not going to be that easy, so thats the dealbreaker for most people.

OK rant over, just have to set some things straight, this is a great example of someone who has no or very little experience with turbos feeding hungry minds, misrepresenting turbos, I am just hearing the same thing from other people that dont know either, its not your fault.

Its easy to repeat what you have heard, its easy to become misinformed as we see in this case. I see it all the time. There are some good books out there that can set things straight.

 

S/C = you need power to make power.

Turbo = you can gain at least 50% more power.

 

SpeedFreek wins

 

thats such a vague comparison.

you compared subaru, audi/vw, mazda, mitsubishi, etc. they all have turbos not superchargers?

then you say that Subaru's STI and Mitsubishi's Evo choose to use a turbo instead of a supercharger.

then you say that TRD offers a SuperCharged TC.

So you really aren't contradicting yourself. You are just comparing the incorrect Make and Models.

TRD is Toyota Racing Development
Scion makes the TC

to my knowledge Toyota, Scion, and Lexus are all under the same ownership.

"I'm not an mechinical engineer, nor due it pretend to be"
im in that same boat man. haha...

 

If I remember correctly, the tC was originally supposed to be turbocharged, which is probably how the car got it's name after Volvo complained about the use of the xC name. I know Eaton makes the TRD Supercharger for our trucks.

Comparing a SC vs TC in this thread should be for our engines only. I would think bringing different cars/engines would each have their unique behaviors making a comparison of which is better not so easy. One engine might work better with a SC and maybe another engine work better with a TC.

I also wonder if there are people that prefer a Turbocharger more cuz of the feeling when the boost kicks in as where superchargers have a more steady pull.

 

just give it the hennessy treatment....twin turbos + supercharger.

 

Look around, s/c is more user friendly than a turbo. I have run turbos stock and modded, and I have installed and driven built cars with s/c's.

It comes down to how much power you want to make and how much you want to spend to get that power.


Its up to the Op what he wants to do, each has a strict following and they as you can tell get "passionate" about their own kind of "boosting"

 

Ive heard of a twin charge set up, but a tri-charge, now thats interesting, I think I would keep that one on road though

 

s/c all the way!!!!

 

Well, first you need to ask your self what you want it for....street or track.

For the track TURBO; because it will perform better on the track. there is a thing called "turbo lag"....you press on the gas a go like normal, but after a second or two (once your building speed up) the turbo kicks in and you go like hell. This is better for the track because you wont spin your wheels, losing valuable time.

Street...supercharger...instant GO, but that is ok because your already moving and not at a stand still like on a 1/4 mile track, your just want that kick to blow by someone when needed.

My vote is for supercharger.;


just noticed this post was originally posted about 2 years ago...you probably already got what you needed lol

 

id go for a turbo in my tacoma. i just love the sound of a blow off valve
