View Full Version : turbo vs supercharger

just wondering how much more difficult a turbo is vs a supercharger. What are the pros and cons of each? What all goes into a turbo kit top to bottom fuel system, computer stuff, etc. trying to get a game plan for the future. I know Timmy and I talked about a foxbody style supercharger now that I'm switching my front accessories to a fox setup, but I know the sc's have their limitations.
some background of the car:
plans are a 331 with power adder
I want it to be streetable
and somewhere in the 500-600 rwhp&rwtq range
I wanted a fast daily driver so I went with a centri, If I wanted a 500-600whp monster I would go Turbo. For a stop light warrior, I would go with the twin screw.
The only differences I know of are the obvious (one needs a belt, the other needs a custom exhaust). I would assume most of the basics still apply, like needing a fuel pump, injectors, plugs, low compression motor, etc.. I've never owned anything remotely that powerful though so I don't have much experience to answer your question.

The only problem is the twin screws are ugly for the 5.0's, I'd love to throw a kenne bell on it, but they just look stupid

All the needed supporting hardware aside,
ease of install, supercharger
more efficient power adder, turbo
increased chance of melting stuff under the hood, turbo
less stress on engine, turbo
most other things are personal preference.
I've owned both, and I like the turbo route better.

That pretty much sums it up. The choices are where you want the power.

Why do you want that much hp?
I thought your car was more of a show car/cruiser.
Have you ever drag raced it before?
Have you ever driven a 500rwhp car before?
Will you have the proper block to handle that much hp?
Is money a consideration?

ya my car is a show car cruiser, but I still want something that can compete with decent cars, cause every once n a while u get the ricer fly by n want to let em know wats up:bounce: I havent driven one, but ive been in a few, and ya I was thinking a boss block, n for right now now oney is not a consideration because Im not spending any on it for now, but when I actually go to do this it may be a factor

Just realize you're talking about spending $10-12k on a powertrain to play around on the street every once in a while. (which could lead to lots and lots of more money if you're caught)
This doesn't answer your original question, but if you have no intentions of using the powertrain, it's not cost effective to do it.
I vote neither.

For a street driven car I think the ease of install and of a supercharger is the way to go, many of them have fully contained lubricating systems, so no modding the oil pan, no sourcing oil to lubricate it, less chances of leaks. and its sometimes difficult to stuff turbos under the hood.
The downside is the parasitic losses that the supercharger naturally causes...
BUT
For a retardedly fast machine, why choose one... choose both compound it!
http://www.hellionpowersystems.com/ has a kit to twincharge the GT500 that can make over 1000rwhp and 1000rwtq with the stock supercharger still in place.

just saying mike with that trick flow upper intake and some of the other stuff you have done.. i think your off the line isn't gonna be as powerful as your top end so something belt-driven is going to be better i think than exhaust just because off the line will feel slow... plus too remember when you start thinking about that power.. 9 inch rearend? my be instore for it.

^^ this video is a turbo cobra against a termi.. just shows that a supercharger still gets it and where at around here are you gonna hit 180? just saying man

This vid you posted is NOT a good example comparing a supercharger to a turbo car.. Those are two totally different cars, I have followed the car on the rights build since he started it a few years ago...
Mike to be honest, if your just going with a car show cruiser.. a NA 331 will be more than enough for what you will be using it for.. I vote neither. I vote do your research like i know you have been doing and select a proper NA setup that will meet your needs. Or keep a stock 302, put forged pistons in the bottom end, stick with your setup you have now and throw a s-trim on it... If you do a good 331 blower/turbo car, to do it RIGHT you will easily have 10k into.. I dont care what anyone says i priced out every single part cause i was going to build one and it was alil over 10k.. Block, rods, pistons, crank, machining, GOOD heads, custom cam, valvetrain, fuel system, all the electronics, rear end.. etc...Then another 5-6k for turbo kit or 3k for a s/c kit.. it adds up very quick.. low 12s and mid 11s on a NA 331 is very do able and Paul has done it with his vert and that will be more than enough on the street.
Just my two cents... and my summary on comparing them all
Twin Screw = perfect for street only
Centri = great for street and strip
Turbo = must have for ultimate strip car

a built 8.8 can hold ALOT of hp.. he will never need a 9in with only 500-600rwhp/tq

cmon now scott, dont go killing my hope for a truely fast car, lol if I go NA it will be a high compression 347, but I figured I would try n go for more hp than less

Im not trying to kill your dreams here, just pointing out facts and stating my opinions.. Its your car and i always say do what you want to do to it and screw everyone else, they arent paying for the parts or driving it, YOU are..
A truely fast car is in the eye of the beholder.. 500rwhp on the street is when you got to worry about traction issues.. Then you have to start thinking about suspension, then once you spend a couple grand on suspension, you have to worry about the rear end weakness since the suspension is getting that power to the ground. So then you upgrade the whole rear end setup.. And then you got the rear end to hold the power to the ground.. Now you have to find a tire to plant it to the pavement...
Im in no way shape or form, trying to push you away from anything. I am just stating my opinons and the things i know and have learned and seen over the years i have been into all this and info i have learned from many well known and educated people.. And as you said this is down the road and im stating some things that you HAVE to consider when building a car for whatever you want it to do and when you want 500-600 rwhp/rwtq you get into big money and many more equations to make it work and be dependable.
