Totally wrong. 160 hp is 160 hp. Doesn't matter if it's measured at the crankshaft or the wheels. The drag from the supercharger has already been accounted for by the time torque is measured at the crankshaft.
Wow, a lot of people talking out of their ass. It never fails to surprise me how many "experts" there are.
it's the whine that makes em more cool than turbos.
well, that, and this gigantic scoop sticking out of your hood. (but you have to have that scoop to be considered cool)
alright, here's IMO, the best you can do with either.
turbocharger is for smaller engines, narrower powerbands, and higher RPM. it induces more lag for off the line, but gets a better top speed.
best a supercharger can do.
now, to be truly cool, the turbocharger is king.
it's for bigger, torquier engines, wider power bands, lower RPM. it has no lag off the line, and it takes horsepower to makes horsepower. lower top speed, but damn, getting up there...
Most Awesome Car. Period.
I'm capable of Googling on my own thanks for offering.
Its just when you throw out a broad comment like that and dont offer ANY info whatsoever, how much should I expect you to know?
I was planning on writing a nice response and hopefully answering the question but I becamed sickened by the fluster cuck of comments that ensued. If the original author wanted to post a new question then I would probably be motivated to answer it. Something like what are the pros cons of different types of intercooling, turbo sizing, manifold configurations, bearing types, lubrication etc and so forth.
My ride right now is a 96 200SX SE-R. Interestingly enough I recently sold off all of my turbo components to pay for my motorcycle and college expenses. In addition to my car I have turboed numerous friends cars, and tinkered with 1.8ts. I am kind of off my street car kick for the moment and applying all of my efforts in designing parts for my universities formula sae car. Currently I am working on a hybrid chromoly spaceframe/alumnium monocoque frame and the exhaust systems amongst other small parts.
So Badger, write!
I'm curious what you have to say about them. Whats your take on the benefits of one over the other? Which is better? Or are they, as I and a few others have said, application dependent?
BTW, "fluster cuck" = LOL! I like that.

Dude!
Help me design a turbo for the 2.5HP Honda GXH50 on my scooter.
Seriously..
I've heard IHI makes turbos small enough....
Edit:
Example 1.... :Q
Turbochargers in most of the "normal" cars are boosting the torque in low mid-range (2500+ RPM) revs considerably, so their torque curve is actually flatter than freely-breathing engines have. Supercharged cars are mostly equipped with system that allows to disconnect supercharger at very low RPM's (or idle), cause it eats up considerable amount of power without making any boost and would make engine weaker that way.
No sorry, the extra resistance from a supercharger will effect it, you will in effect have more engine braking, as their is greater frictional losses directly applied to the engine.
Personally I tend to prefer turbos over superchargers. Simply because they are not parasitic on the drive train of the vehicle. Yes turbos CAN have lag if you are a moron and buy some turbo that is improperly sized or you want the absolute most power (Supra and RX-7 owners with deep pockets come to mind). However, if you take the time to size the turbo and select the supporting components, you will find you can make awesome power with almost no lag. Not to mention that if you get a good launch out of the hole, or you select the right corner exit gear you can almost always remained in the spooled zone of reasonable turbo. Not to mention with a turbo you have the ability to easily alter boost for different driving situations or vary boost by gear/wheel slip.
Not, I don't think Superchargers are necessarily scat. For OEM and a few other applications superchargers are the way to go. I got the opprotunity to get some behind the scenes looks at products coming from the Blue Oval this summer during my internship, and be on the look out for some cool supercharged powertrains from them.
I do believe his statement is correct.160HP is 160HP. Of course, the "trick" is that you have to.. get ready for it.. measure HP output with the supercharger attached to the engine and functioning. :Q
So you're basically saying that if you hook an accessory up to the engine while it's sitting on a dyno, and run the test.. the dyno will read the engine as if there was nothing being driven by it?
If you say so.

A turbo would be quite novel, but I am pretty sure that you would never be able to get it tuned correctly, or find one small enough to work for the engine. If you want to sh!t yourself on your scooter, pull of the airbox, give the carb a few turns and throw a small nitrous system on there. That oughta give you some skid marks in your undies.

Aww.. but a turbo would be much more fun..
Even if it only boosted power by like 20%.. it would be worth it, just for the do it yourself hobby aspect.
I bet you could get it tuned reasonably well, though.. If you knew what you were doing, you would just have to scale it down.. and with a bit of tinkering..
The turbo on that 5HP Honda engine driven barstool is pretty small, but probably not quite small enough... Hmm..
What happens if you put a turbo that's too large on an engine? Bad turbo lag?

Very bad lag, or you might not even put out enough exhaust energy to spool the turbo then basically the turbo just acts as a restriction in the system and you will make less power than you would without the turbo.
Yeah. I figured. That would be bad.Originally posted by: BadgerFan

Well, surely there must be CFM requirements for optimum boost etc that come along with each sized turbos specifications, no?
I could probably measure exhaust output from idle to full throttle, and try and find something that would work.. Or is that how you would normally go about it?
Is there a formula to figure exhaust output like there is intake CFM?
/me scampers off to google
Nothing much, I'm still lurking here most of the time, I just haven't had much to say lately
Engine braking isn't why horsepowers are needed
160Hp on crankshaft/wheels is still 160Hp no matter how it's achieved. Blown 160Hp engine may have bigger fuel consumtion, weight and cooling requirements, but it still makes 160Hp. You don't claim that when 2 cars are accelating 0-60mph in 10 sec, then one car's 10sec is faster than others, do you ? Extremly powerful per displacement engines tend to have really bad turbo lag: I've seen Ford Sierra with heavy truck turbocharger mounted on it that made 509 RWHp out of 2L 4-banger (most of the engine was stock!). It ran low 12sec times on track but start was always very slow and turbo really kicked in after about 2-4 seconds. I have also seen finns ~600HP 1,5L russian IZ-412 and about as powerful 1,3L Toyota Starlet.
