SUPERCHARGING vs. TURBOCHARGING

thoughts a opinions on these 2 paths to choose for better performance as well as pro's and con's of the 2...they are similar but some poeple might like one more than the other

I think it depends on the car and what you are looking for out of the car.

turbo charging depending on the size of the turbo will produce lag until engine rpms reach boost point, while supercharging will give power from a lower rpm but still produce through out the rev range.

Turbo charging can and will produce peaky hp while supercharging will produce smoother hp curves.

For open road or circuit style racing turbo charging is better while in drag racing super charging is the way to go. Of course that also depends on the size of the engine. Turbo charging is also known as cheap hp

Superchargers are more expensive and vibrate a lot. Generally, turbo charging is better.

turbocharging either of my camaro's would be atleast 2 grand more than supercharging it..ive looked....supercharger with aftercooler installed would be around 7 g's and twin turbo kit installed would be no less than 9.....i dont favor one over the other but i do favor not being broke..haha...peace

supercharging would be more ideal for a daily driver. turbocharging is more flexible than a suercharger, better for racing overall. turbos are generally much higher maintenance. if you don't take care of it properly, you'll run into costly problems. i mean you have to take care of the car, supercharged or turbocharged, but between the two, the supercharger requires less maitenance attention.

you are obviously going with centrifugal s/c, which needs to be stated. that can make alot of power, and is more of a driver's car. why not build one of each?
the question is really more along the lines of what other mods are you going to have to make? if you tt, it is more power, which means more "hidden" mods, or, the stuff you have to do b/c you tt'd it. the s/c isnt as bad, but it still has em. it just depends on how you want to spend you money. you can spend more on tt's, only to find out you are going to have to spend more in "hidden" mods... but it could be the same w/ an s/c. i would consider that. what kinda power numbers are we talking, and what kind of powerbands?

im talking over 620 horses when i got done!

I disagree with that one big time... In road racing, torque coming out of the corners is a huge advantage, which a roots type blower provides. Why do you think Mustangs and Camaros romp all over S2000s in T2 (nationally) when the S2000 has about the same hp/weight ratio and has a better suspension and is lighter? A roots type blower does wonders for auto-x and/or tight road courses since low end torque is nearly equally boosted as high end power.

But RS, what motor are we talking about here? If its a 350/LT1 then you are getting ass raped if you think a blower w/ aftercooler will run you $7,000. A LS1 kit, which is generally much more expensive, will only run about $5k installed. If by chance you are running a 305, then why the hell are you running a 305? Get a real motor.

im putting a vortech g-trim sq supercharger w/aftercooler in with a polished finish....go to vortech's web page once and look it up..i think its around 5500 or so....im putting this in my 2000 SS....i was thinking bout twin turbo for the LT1 down the road sometime

$6,434.30 exactly from vortechsuperchargers.com....that does seem a little expensive...but its a +150 horsepower boost...so i'd do it

Both. :D

Nowadays turbos are probably the better choice.

I would have to go with a TURBO hands down.

i like superchargers more, personally. Im an old muscle car kind of guy, so just for pure aesthetics, a nice big ass blower sticking out of the hood of a nice car (say, Hemi Cuda, hehe) it just sweet. Also, whenever you hit the gas, you can watch those butterfly valves open. Also, for the musclecars, big V8's, that produce a lot more power on the low and mid rpms, its better to have a s/c to provide for that, instead of a turbo which will lag until it's too late for the larger engines. So. Yeah.

Superchargers add friction, are "lazy": they help low-end power, but they don't rev as fast or as high as a turbo car would. They also vibrate a lot.

i love turbo chargers a lot more.
superchargers are kind of lame. well not really but compared to a turbo its different.
i really like the sound of the blow off valve. and its easier and more fun to tune and get a lot of power.

Both -> Lancia Delta S4 :cool:

A supercharger will give you instant boost, preserve your low-end torque, and give you linear increases throughout the powerband. Superchargers are mechanically simpler, have their own oil supply, and don't require tons of extra plumbing. However, to get the kind of boost you would get from a decent-sized turbo, you'd need to start changing pulleys. You might be able to double your boost, but you'll also reduce the life expectancy of the s/c this way.

The turbocharger is more of a hassle in almost every way, but a turbo (or two) properly matched to your engine will give unparalelled top-end power. Turbo lag is the biggest turn-off to most people, but a modern ball-bearing turbo cuts that down a lot. If your motor is highly modified and revs fast, the benefits will probably outweigh the drawbacks. If you're trying to capitalize on the strengths of a nearly stock V8, think supercharger.

I saw a twin-supercharged Corvette LS1 engine in a Camaro one time. I think it went though a set of tires a week. I also saw a Camaro with some really ghetto exhaust piping and the turbos out of a 300ZX. It was actually driveable, but low and midrange seemed choked. A proper TT setup would certainly yield better results. BTW, I assume you have a Camaro, at least I read something that made it sound that way. Maybe I should've checked before I started typing...

Bottom line: it really depends what your car is and what you want it to do. If you are doing a camaro, you probably want s/c, but your torquey motor could make up for it (unless you drop a lot of compression to accomodate the turbo).

Ive seen good things done with turbo..but no doubt ATI Procharger is were its at..especially for 8's

turbocharger

I like the fact that on a turbocharger you can vary the boost to fit your driving needs at that moment. If it's raining and lots of power is giving you problems, or for daily driving you want to minimize engine wear, cut down on the boost. A guy comes up and wants to go, crank it up and have fun. :) S/C means you have to change out pully's and that just takes too long(I'm impatient).

I'm not sure if my Grandpa Buick belongs in this discussion or not, but I'll put in my two cents anyway.:D

I recently purchased a Buick GS/ with the Supercharged engine. It's 240 hsp, which is more than enough for me. I really bought the car for the ride and creature comforts, but it's nice to know I can get out of a sticky situation out on the road.

I've never noticed any vibration problems coming from the engine. It runs very smooth and decently quiet. Some of you may be talking about different kinds of supercharged engines....like in dragsters or something. Then that could be true in monsters like those.

:sun:

ill go wit turbocharger!:bandit: :smoka: :smoker2: :ylsuper

id pick Supercharged because it gives out more power

out of curiousity, why go with one or the other.....go with both. i was dumfounded when i saw an engine in the 47ft coast guard motor life boat. it was turbocharged and supercharged, at this point in time i am lost, i didn't think this was possible, if someone could explain this to me, feel free to e-mail me at [email protected]. from what i saw it is a real work of art, but is also a detroit deisel. i understand that the compression of a deisel is much higher than an unleaded vehicle, so would it be possible to put in a 350?

thanks

Having both SC and turbo is called Twincharging. HKS made a twincharger kit, and theres a few MR2s out there that are twincharged. Generally, though, twincharging is pointless, as you can get more total power going with a well-planned supercharger or turbo.

The method behind the madness is to try and reep the benefits of both worlds.. a supercharger puts out a nice flat power curve on the low end, so you get that massive power boost off the line, but once you get into the higher rpm ranges, the S/C kicks off and the turbo's kick in, which gives you the higher max power that turbo's give.:alien2:
