Default Supercharger vs. Turbo

Here's a dumb question. What advantages does a Supercharger have vs. a Turbo, or vice-versa? I know the Supercharger doesn't suffer from lag. What other characteristics do each display that are unique?

Thanks, in advance, for the help.

I bet you'll get some responses you're not looking for. Try www.howstuffworks.com .


Supercharger have parasitic loss, turbos have lag.
Superchargers are stuck at a certain boost, turbos are not.
Superchargers have linear power increases, turbos have a rush of power.
Turbos are much easier to do with our cars, cheaper too.

Here's a pretty good thread from a while back, goes into some s/c t/c info discussion.


Search for my name in "Aftermarket Forced Induction" , I've replied to a few supercharger-related threads, and not much else.

If you don't mind reading a LOT, here's a thread I've been following for over a year now, over on RS25.com

warning: a lot means a LOT, I dare you to read the entinre thread in one sitting, I doubt I could do it.

An advantage to Turbo'ing is that everyones done it. You can get help. Most kits are fairly plug and play. Not as much custom fabrication needed. Very easy to add more boost (very easy to get boost greedy too). Downside is that there's alot of stuff going on and it can be complicated.

On the supercharger side, you'll have one of a few subarus that have one. It's very simple/safe (no boost spikes) and very reliable. Instant boost is nice depending on the type of supercharger you use. Torque under the curve is phenominal. It drives like it has a bigger engine.

Default Superchargers eat little engines? Do you smoke crack?

I have a supercharged 99 2.5 RS with over 40,000 "blown" miles. The only thing that is starting to show its age is my poor tranny.

I have had ZERO, as in "0" problems with my supercharged/ intercooled Subie.

What can I do that a turbo Sube can't; I can accelerate up an on-ramp..........in 5th gear...........at 30 mph.

Torque baby, lots and lots of torque.....

Thats the rub you see... nobody makes a supercharger kit. AFAIK, DNT is still working on theirs, and the other company that made them (Rimmer) you want to have nothing to do with. Basically its a custom kit if you want one right now. I really wanted a positive displacement blower on my car, but It just wasnt feasible with the way the market currently is. Turbo is going to be many many times easier since there are ready made kits and lot of help. (Cheaper too!)

i LOVE these threads. haha

For one, most points here are valid. If you get a s/c plan on doing your own work, as kits are not available. Unless DNT finished theirs.

Being I have a s/c RS, I have to say, I like the s/c better then a turbo. For me it means less worries. I just rebuild the eaton charger, and the car runs like a champ. Esp with the new clutch that can hold most of the power.

In anycase, if you want boost, save a lot of money and learn about the car, or just get a wrx.

If you want to know more about my car do a seach under my name.

Hopefully you dont see a red-x

Has anyone ever compiled a list of factory or aftermarket stand-alone (not an integral part of the intake manifold) superchargers? If not, could someone start one? Please???

I'm not really up on what cars come with, or came with blowers. Pontiac Bonneville, VW Corrado, Buick Regal, some Mercedes.......that's about all I can think of. I'm guessing that something with similar engine displacement would be best?

I've been curious about this topic for a while now, and I wouldn't be against trying to set one up on my car, but I don't know what would be the best unit to start with.
