that a turbo at equivilent PSI would make more HP then a supercharger?

I always thought they would be the same, and that a turbo just had more potential for upgrades...

thx

 

aw **** i hit over 1000 post and didnt even notice!!! got damn it !!!

 

yes because a supercharger takes away pontential hp to power itself

http://www.turbochargedpower.com/Tur...%20Blowers.htm look at the efficeny section, a s/c at 12 psi is the same as a turbo at 9 psi.

 

If I remember right I think the formula is:

For every 100HP a belt driven S/C makes it uses 30HP to do so.


All aside I would rather have a S/C over a Turbo.

I always associated a S/C with american muscle and Turbo with import rice.

With the exception of the Buick GNX and Pontiac TTA...........

 

also mainly to do with CFM.... you produce say 20 psi at 600 cfm from a s/c and 20 psi at 1000 cfm.... obviuosly gonna make more power with choice number 2

 

well, it's not easy to compare... mainly because they are so different...
turbos help make engines more efficent if used correctly, or they can add more power. a blower just adds power.

 

Its not that easy.. but when talking about efficiency.. turbos are more efficient than superchargers

 

of course they are more efficent, they don't take the engines energy to run them.

 

So 2 cars , assuming that all things are equal, as in mods, quality of tune, engine and so forth. The turbo one would have more hp/tq then the supercharged one?

Then why do people go with super chargers, just for lack of turbo lag?

 

that and they sound damn awesome at WOT

 

for the immediate torque, thats why top fuel dragsters use them

 

It's really not that easy. It depends on the size of the turbo and other things too. It's not as simple as saying the turbo will make more hp/torque. This may be true at peak but probably not through the whole powerband. The SC makes torque down low and up high where the turbo is just making torque after it is spooled up.

Niether is better, both have pros and cons, both can make plenty of ponies.

 

Turbo's are more expensive, labor intensive, produce more heat and tend to have little things go wrong woth them more often than Superchargers.

 

turbos=power for free(wasted exhaust gas)
s/c uses belt off crank(power) to make HP
Our cars would probably be SRT killers with turbo....

 

with a good setup and not a retardedly oversized turbo, there will be some lagg but youd hit full boost long before the supercharger got there givin you more mid end power.

 

there not that labor intensive I did one in an n/a eclipse only took me a day to do with a buddy hardest part was taking off the front bumper cause it was a pain but changing the manifold, adding piping fuel stuff like that was all easy ESPECIALLY WITH A BUDDY.

 

But the SC takes a fraction of that.

 

so as not to have another war thread let us keep this discussion based on us all assuming that the sc'er and turbo put out the same power (different psi) or same psi (different horsepower/torque) levels. this can keep the thread even so people can understand this better.

 

did you just say a turbo would get full boost before a sc?!?

how the hell.....

 

There are so many pros and cons to each its hard to compare the two. In the end, all it comes down to it your preferences, your expectations of the engine, power band and power delivery. I personally prefer turbos, theres nothing like the feeling of hitting full boost and getting pushed back in your seat. But thats just me... Oh, and for CodySS: The domestic guys are very quickly jumping on the turbo bandwagon. Some of the fastest nitro coupes and street tire cars in the country are turbod' and theres good reason for it. Better control over power delivery. Instead of blowing the tires off when the light turns green, a computer can slowly turn the boost up as they make the pass. Turbos are definitly NOT just for imports, just ask Lingenfelter Performance Engineering

 

look at the evo, my friends was boosting 23 psi and hittin it by 2500

 

no the reason they use them is conformity. they have been supercharged forever, and to keep competition as level as possible, that is a regulation. its the same thing in like NASCAR, where for example the throttle body inlet has to be such a size and whatnot.

and, for the most part,s/c's are an easier install due to not having to change out any manifolds (i turboed a N/a eclipse also--granted it is very easy due to the engine compartment configuration--but that is just one application) and can be fit in tighter areas, which is why v8's mostly in the past have gone the supercharged route (space and ease of installation). although many are spending the extra money and going the turbo route now.

a properly sized turbo for the specific application can have minimal turbo lag to where it almost feels as if there is none.

and you cant say a supercharger at the same psi level vs a turbo at the same psi level. one turbo at 15psi can really suk ass if it isnt in its efficiency area, where another turbo can be flowing a whole lotta air and making a lotta power at 15psi. same thing with superchargers. Point blank--this isnt an easy question and some corky bell reading would be most beneficial to everybody

 

A top fuel dragster would explode a turbocharger simply from the shock of the exhaust gasses going through it. It would be extremely expensive and need to be replaced too often. Also the exhaust gasses would have to be collected into a single pipe and then go through the turbo, i.e. no.

The supercharger in a top fuel dragster uses 1000 horsepower ALONE.

 

thx more responses please

 

Turbos are not tax free. They create a restriction in the exhaust which creates more resistance against the piston during the exhaust stroke. I'm not really sure how you can successfully compare them unless you take 2 of the exact same car and design them to create the exact same boost levels/CFM flow rate at the exact same times. Very complicated since they have differant efficiency levels.

It would also vary on what type of super or turbo you are talking about.

Superchargers:
-Roots
-Twin Screw
-Vanes
-Centrifugal
-etc.

Turbos:
-Hybrid
-Twin Scroll
-Variable Vane
-etc.
