Not enough discussion going on so:
Which power adder would you rather run: Nitrous, a turbocharger or a supercharger?
Why? Which of these would benefit your car and your style of racing? Or perhaps you just like one of these in general.

turbo....efficient, relatively small in size with the exception of an intercooler, sizes can be juggled to fit engine type to a T, and no parasitic loss. they take the cake.
i dont know a whole lot about nitrous other than if you don't install the correct type of kit (dry, wet, etc.) you can fry stuff pretty easily. plus filling up a bottle sucks. you can be stealthy with the install though.
superchargers are nice i guess....but i see no advantage to them over turbos other than ease of fitting in a V style engine, low maintainance in the self-lubed units, and no lag. plus they are slightly less expensive than turbos.

turbo.
while nitrous is the cheapest way to go fast i don't think it is nearly as reliable as the other power-adders and it isn't always on.
superchargers are alright but then again they bring in parasitic loss, certainly not cool in my book. scott from what i've seen superchargers are generally more expensive :?

well, i have to agree in some cases supers are more $$$. but if you look at the V8 croud, one of the reasons they spring for the supers more often is price, among other things. a turbo setup for a large engine usually requires 2 turbos and alot of plumbing = more money

when you are "racing" you are governed by rules.
Very few racing classes allow for adding forced induction, and none allow for nitrous.
and I could give a shit about drag racing
in road racing, usually only some level of a motor build is allowed. Ranging from a "stock" build (showroom stock, SM) to a full race motor build (WC, production, prepared, etc)
ultimately, you want to get the most power as legal under the rules. high dyno numbers, low 1/4 mile times, etc dont mean a damn thing in real racing.
Nitrous! Cheaper and easier to install, and just as reliable if not more so when done correctly. This from what I've read, I don't know a damn thing myself. No lag, no loss, no custom intake and exhaust manifolds and crazy piping filling up the engine bay, no extra higher maintenance parts, just trade cash for more power at WOT. :wink: For racing, any of this kind of crap is either illegal or puts you in a big $$$$$ class you can't afford to run in, so no thanks. But I must admit, for my street car, I would enjoy some nitrous if I had some extra $$ to flush. Nitrous isn't really that different from any method of boost-- add too much and you break things. But I'd keep it well within the limits of the engine and get it running correctly, and it wouldn't hurt reliability at all (well maybe just a touch).
I need 2 bottles. big ones. by tonight!
I always knew you were a ricer chaddock!
I'm partial to turbos because they are more efficient than superchargers and they're not just a temporary fix like nitrous. I could turn up the boost for the strip or track and turn it down for the street. I could just not use nitrous at all on the street or whatever but I wouldn't wanna be spraying at the race track.
In road racing of course turbos are not allowed in most classes so its sort of a mute point. For rallying its perfect 
well correct me if I'm wrong, but a single turbo will be felt most of the time at higher rpm's once it spools up. Whats the advantage of twin turbo's (i.e. Supra's and the new mercedes V12  hock: )? Does this help with extra bOOst through the full rpm range?

Twin Turbos are (usually) smaller and spool faster? I know you can also have them in line and the one will spool the other, I think trucks do that. Alas I don't do that boost crap so I'm not quite sure what I'm talking about

Thanks Evan! Your entire post offered no answer to the question.
But it did remind me that a N/A set up might be desirable to some people and I should have had it as one of the choices.
I'll brush off your comments about real racing. They are about as lame as a marathoner telling a sprinter he isn't a real runner.
I myself am also a fan of turbochargers. On a 4-6 cylinder engines I think they are the perfect choice for making a bit more power. Kits, if your car is not blessed with one, can be expensive but nitrous oxide or a supercharger isn't going to be free either. Generally they make more power, boost can be easily adjusted, they don't need to be refilled, and when you arn't running on boost you can still get amazing gas mileage.

*edit, just saw this:

A twin turbo set up where both turbos are of equal size is usually only going to be found on a V engine displacing more than 3 liters. It isn't practical on a smaller inline or horizontally opposed 4 cylinder engine because there won't be enough exhaust gas to spool both turbos.
They will not make as much power as a single large turbo, but they also wont' lag as much and that is very important in cars sold to the general publics.
A sequential turbu set up has two different sized turbos. One smaller one that spools up quick, and one larger one that creats more power and will literally take over when needed.

you said what "power adder" for racing, none of which are legal for racing.

God forbid that the teams/drivers prepared their cars well and drove well to win, rather than with gross amounts of unreliable horsepower....

Silly boys. I bet neither of you would disparage the racing in the turbocharged F1 era.

Well no but he didnt ask about 1.5L turbo motors from 30 years ago

G.Irish Wrote:Silly boys. I bet neither of you would disparage the racing in the turbocharged F1 era. oh hell no. Im not saying b00st sucks, or anything like it. Hell I drive a turbocharged car.
Im just trying to steer this conversation towards reality. If we are going to talk about something, how about it being constructive?
We all pretty much know the pros and cons of each type of forced induction (and nawzzzz)
The most important thing is how do we apply our knowledge to our racing goals in order to achieve them.
KPWSerpiente Wrote:Which of these would benefit your car and your style of racing?
evan's right...
teh b00st has pickled my brain, but for a lot of racing series, they dont allow forced induction. i'm not saying that drag racing isnt real racing, but like evan, i dont really care too much for it. the setup for road racing, autocross, and drag are all pretty different, so using forced induction for our style of racing is a moot point.

I'd put nitrous on that thing too. I live my life a quarter league at a time. 8)
