Why turbo? It seems that most people on this site favor a single turbocharger over a supercharger. I have grown up with my dad always supercharging everything and that is all i have known so i have always favored superchargers. I was curious as to why so many are in favor of turbochargers, also those who favor superchargers feel free to plead your case. Also, what about turbo lag, and lack of power off the line with a turbo?
Turbo lag is not a issue with todays turbo technology unless you select the wrong turbo for your application.
And if you want torque off the line, there are 2 step boxes that can let you spool up the turbos on the starting line, also you can use a transbrake to build boost.

In the NMRA, SSO (28x10.5) cars have much different rules for turbo and blower cars. Turbo cars must run smaller head units, 80 less cubic inches, and usually 150-200 pounds heavier, and the turbo cars are still teh front runners in the class. That tell you anything about how dominant turbos are?
Turbos
Pros
Cons
Superchargers
Pros
Cons
Vortech and Procharger have a strong foothold in the market, and that is why you see them on so many cars. I have owned several centrifugally supercharged cars in the past, as well as a few Turbo cars, so I'm speaking with lots of experience. Turbos are a superior power adder once you get past the cost.
Turbos
Pros
- More mid range, low end power
- Adjustable on the fly boost
- Lower parasitic power drain
- More power per pound of boost
- Much quieter car
- Reliability
Cons
- More expensive initial output
- Cool down period
- More complex plumbing
- Some turbo lag with larger turbos
Superchargers
Pros
- Cheaper
- Easier to install
Cons
- Belt slip issues
- Much less low/mid range power
- Pulley change to change boost
- Higher parasitic power loss
- Massive loads on #1 main bearing

When I first got my T/A I planned on supercharging after heads and cam. I was always concerned about turbo lag. Then I started reading a lot on this site and learned more about turbos. I realized with the right application I can make all the power I want with practically no lag. I wouldn't have to worry about belt slippage either. Unfortunately a turbo setup is typically pricier but the phamspeed kit is realtively inexpensive.

As of right now, I believe the fastest LS1 in the world is supercharged 
Also, does anyone have anything to say about the PTK LS1 kit? http://forcedinductions.com/GMkits3.htm

3400 bucks for hot parts (headers, downpipe, wastegate, turbo) and all the lines. I think that also includes an alt. relocation bracket? Maybe not. Talk to LT1-7, that would be John. www.phamspeed.com You'd still need an intercooler, BOV, and the charge piping, which you could probably get a mufler shop to bend for you.

Fastest? Or Quickest?? I'm sure the turbo cars will be getting FASTER and QUICKER this summer. Hey...who is building that car that was in HotRod a few months ago that was being stripped, Twined, and jigged? was that @ W2W's shop? Supposed to be looking for the 7s?

Thanks for the info guys, but i still have to go with superchargers, unless i can still be convinced. I go to NHRA dragraces often and the top fuel dragsters and funny cars are the fastest cars in the world right now, and they are all supercharged. I know that isnt for street use, but it just shows the superiority of the supercharger.

those are not the same kind of supercharger that are in the ATI or Vortech kits

The nitrous guys hate us, and the centrifugal guys can't find a belt to stay ON for the full 1320'. I love this!
Keep thinking that way, and you'll be passed. Maybe not in a sanction, but anywhere else, no weight rules apply, and turbos never lose! That's factual.

SC-
Ive went the SC route and i bought the ATI kit and had belt problems from hell along with alot of other people on this board... then i upgraded to a SDCE spring tensioned kit and belt slip was in the past. Then i was given a chnce i couldnt pass up... so i went turbo because for street car they ARE the fastest.
We will see how i really feel when my kit is done.

if you would have gone Vortech you wouldn't have had any of those issues. my personal opinion is superchargers are better for the street cause of a more linear power curve, and turbo's are great for the track/racing cause of the top end pull they have.

SSBlue, I am a turbo fan, don't get me wrong, I was just stating something which I knew to be fact. In fact, I'm opening up the car tomorrow to start fabbing up my own little turbo kit.

Look at mike morans car, it really shows that supercharger superiority when it comes in with less inches, more weight, and plows 10-12 MPH faster than most other people are going in the class
In every single form of drag racing where turbochargers are allowed on an even playing field, they dominate by a massive margin
There is no question about it, turbos are superior on race cars. Top fuel cars right now arn't a question of horsepower so much as traction. Untill they improve the amount of traction available adding more HP is going to do nothing but create a smoke show.
