turbo or supercharger

i have a 383 and its enough horse for now...but im lookin to either supercharge it or turbo it...which would be better and are there any sites out there that sell kits to do this...thanks

this will be one long thread. i would supercharge, why because it just more user freindly. turbos are unlimited horsepower, but your engine can only handle so much boost. Supercharger is a belt drivin so it is limited by your motor. IMO !

banks

yea banks knows there stuff. that would be a good source.

I believe they have a kit just for a 383 but im not 100% on that one

John?

shit both are cool as hell but the s/c is better in the long run from what im told, turbo's will go out and require more work i think s/c is more dependable. but that blowoff sound a turbo kicks out sure does sound sweet!

A guy i know just installed a Procharger kit. Runs mad numbers

whats the banks website and can i get prices from the site?

you can put a blow off valve on a supercharger too...

I'd say turbo, more expensive initially but more efficient than supercharger. I dont think a supercharger is necessarily more reliable than a turbo charger, from what i've seen it's actually the opposite. As has also been said turbo=almost unlimited horsepower.

where can i get prices on turbo kits or supercharger kits

depends on how much u know bout turbos some can cost like 10k+ some 1K or hell u can build a junk yard turbo system for cheap. Turbo need to be rebuilt around every 60k as reccomened by most turbo companies Greddy,apexi,......

i would buy procharger.com A guy I work with told me about them and I got their catalog in the mail... it's one of the best forced induction systems around. They make it easy to install and their chargers are intercooled which helps a lot. If you haven't went to their website and requested information, then you need to.

Turbos are much more efficient, More reliable, and will make a lot more power.. and yeah, the BOV noise is cool too..
*no, you will not need to rebuild a good turbo every 60,000k so long as its looked after.. I just hit 125,000miles with my turbo before It started burning oil..
The only downside is the time and $$ spent, to fabricate, install and tune a turbo'd system..

But instead of an overpriced "kit" (which are never completly bolt-on) You should look at doing your own custom turbo set-up.. Or look at some of the custom turbo set-ups others in the forum have been using..

Agreed a well maintained turbo can last as long as a supercharger. Before i looked into forced induction much i got the procharger info packet and was SOLD. It sounded awesome and looked to give great results but after meeting people who had the procharger setups and have since gone with turbo setups none have regretted it. Turbos make power without "loosing" power. For instance a 600hp turbo car will take gas and be as drivable as a 600hp car can be, however a 600hp supercharged car will get the gas mileage of a 750hp car (actual power before paristic loss in blower drag). Both are great (supercharger and turbo) but when i go forced induction, it will be a turbo setup.

that video was awesome, 30 psi on 91 octane. Thats why superchargers are better. Just the same power potential, far better low end torque, and they wont get so hot that the manifold goes red or the engine blows up. Belt driven all the way.

Do you even know what you're talking about? I'll give you a comparison. My T-trim'ed 306 mustang is making a little over a pound, pound and a half of boost at 3000 RPM's. My buddies 306 mustang with a T70 turbocharger makes 12 pounds of boost at 3000 RPM's. His car makes 515 RWHP and over 650 RWTQ. Turbochargers on V8's OWN superchargers in the low end, mid range, and top end. Why do you think at NMRA races, SSO Turbo cars are limited to 360 inches, while blower cars can be 420 inches with physically larger blowers, weigh 200 pounds less, and still the turbo cars are winning? Because turbos OWN.

man you must have a shitty car then...............

But anyway, im not talking 600 hp im talking what that Camaro was running, with that setup, stick 30psi from a turbo and you wont be able to run 91 octane, sure turbos are better than super's with race gas, but i like driving my car, without the need to dump $100 for gas.

You completely misunderstood what i was saying. I don't think you know what you are talking about.

new the honda guy would go with the turbo.

No real sense in argueing with him. Lost cause

as you can tell from the bickering... turbo's and superchargers each have their upsides and downsides... its an opinion thing, and also depends on what you are looking to get out of it...

In addition, i'm not talking strickly racing here either, If i wanted a drag setup, then my opinion would change.

I'd say turbo, more expensive initially but more efficient than supercharger. I dont think a supercharger is necessarily more reliable than a turbo charger, from what i've seen it's actually the opposite. As has also been said turbo=almost unlimited horsepower.

:iagree: thats the total truth, there is no other answer, :sunglasse thank you.

I'm just saying thats what most turbos that come from like preturboed cars say to. a good turbo like one u would buy directly from those companies can go awhile but that is what there rep told me when i was looking at a Mitsu eclipse.

both superchargers and turbochargers, if done right, can be incredibly reliable. i don't think reliability is a valid arguing point... the only factor is if the setup was done in the correct way, if it was, then odds are both will be equally reliable. there are way to many variables in reliability to compare them...

i appreciate all ur comments and i didnt mean to start any problems...but im still stuck on the price deal...ive been looking all day online and i cant find any lkits for a 383...n e one know where there are any out there

they did tell u to look at banks didn't they?
anyway, if u haven't, here's the site

btw, i believe their setups are for all small blocks, so a 383 small block would work just fine...

both a turbo and a supercharger are parasitic. if you put enough money in the turbo, it might be slightly less parasitic (bearings propeller shaft and lube). you also have to remember about turbo lag. it all comes down to when you want the power. high end, get a turbo. right away, get a supercharger. most of the time you supercharge a pushrod cause they generally cant rev as high as the smaller ohc engines. if you have an LS1 or something that can rev up to and over 6 grand than a turbo will work really well. the big displacement engines generally have superchargers to get the power lower in the torque curve...

If by slightly less you meant 30-50hp..
A turbo will draw about 5hp entirly in exhaust backpressure *which isnt necisarily a bad thing, especially in small engines..
Ive seen some superchargers draw as much as 50hp off an engine.. some more, some a little less..

Everyone also takes the turbo lag thing way too far.. Turbo lag is almost completly a thing of the past..
In my car if I power brake, at a dig I can have 8psi right off the launch, and have the turbo fully spooled under 3000rpm..

If you want all-out power and GT car G's go with the turbo. If you get the right set up and build the motor to handle the boost you can run up on like 25 psi but that's more for racing. I would go with like 15-17 psi if you want a semi-streetable muscle car. A supercharger is a different story. You can get them from like 3-12 pounds of boost depending on what you want. In my opinion, I've owned both, go with the supercharger at or below 10 psi. It gives a great deal of power without sacrificing too much driveability, plus I would have to say that if you keep a supercharger well maintained and it is a quality charger it could last nearly the life of the motor itself. But that's all just an opinion.

PS Look into Weiand, Vortech or Powerdyne for superchargers. They might have what you need.

PS2 If you have the room for it in the engine bay maybe a twin turbo setup with two rebuilt T25's (from 2 Mitsubishi Eclipses) would run great. If not the only other thing I could tell you would be Apex'i but good luck anyway.

As has been stated, it's all personal preference. If your wanting something that goes under the hood, go with the turbocharger. If you really don't care about that, I think this:

Looks really damn cool. Like I said, if you want something to fit under the hood and you were choosing between supercharger and turbocharger, go with the turbo. Otherwise, See above.

Its all up to personal preference i guess. There is no argument that a can support that a turbo and supercharger on the same level of power loss though. The lag thing IS a thing of the past IF set up right. Turbos hands down are more expensive, lots more tubing and harder initially to setup but the gains are worth it. If you want easy power (and cheaper) go with supercharger but if you want efficiency, gas mileage, and ultimatly more power go with turbo. I've seen articles on LS1 turbo firebird that got BETTER gas mileage with the turbo than it did without and picked up gobs of power. A close friend of mine ditched his belt tossing pro-charger for his T76mm turbo and car matched his fastest time with the blower first time out! His car is completly drivable around town and he's currently setting it up for 8 second passes! Blowers are cool but they're becoming out dated quickly.
