You should ask a more difficult question if you want to test wat i kno off the topof my head.
-Detonation
-Injector Duty Cycle
-When a Centrifugal Supercharger hits full boost and why
-Why superchargers suck on Hondas

Well, you said we should.

LOL ok Sov i will answer all that i can from the bottom up.

Different types of SC need to tell mi which one although i fig you would be talkin about the roots. In that case here is wat i THINK.
IV. FWD + ROOTS SC = Lots of wheel spin. And this type of SC is not efficient at high revs.
III. Not exacty sure when it makes full boost my guess is that it would depend on some different factors. All i kno is that boost increases as the revs does in response with the engine. So you would make boost all the way to redline. Dont fell like goin all into detail with it put you get the picture.Since i have a high rev Si i think it would be good for ME.
II. I have no idea. Haven't taken a class or read anything about it. But i gusse of the top of my head you be somethin to deal with the rate at which fuel is injected into the engine. BS maybe idk.
I. Can you be more specific with this one. Like what do you want to know about it. And in what context.

O and lets not do the whole turbo vs supercharger thing and comparing them. Is up to your own preference what you want out of your car. I kno wat i want so i got wat i needed.
Thanks for the info on the forum it helped out ALOT

4 - Roots = high amount of heat. Superchargers in general use engine torque to make power, which in itself is a problem for the low torque honda machines. I found that the car didn't really spin the wheels much, but I wasn't making a ton of power either. Centrifugal with an aftercooler isn't as bad, but you're still using power to make power which is tough on a Honda. Plain and simple, Honda's perform with Turbochargers for that reason.

3 - Centrifugal makes full boost at redline. This is because the RPMs dictate supercharger speed, the faster it spins the more boost you make.

2 - Basically the percentage of the injector's capacity that is being used to inject fuel into the engine. It's a little bit more complicated than that but that's the basic idea. So you had the idea on that.

1 - What is it, and why is it bad.

I've pretty much answered all of these questions on this forum, just making sure you're reading.

4. Turbos dont give you power for free. One might say it cost a bit less but there is still that back pressure thing. I have some info on that somewhere i will look it up. O and i kno about the tq thing and its true the points you made but in the long run the SC is gonna cost me less in stress with repairs and stuff. The Centrifugal with the after cooler will still have a flater tq curve than turbo which i like.

3. Wow i actual knew that i should of added it.

2. Ahh i see. Now i am gonna look it up and see how it works.

1. I still need you to be more specific lol. Like in the engine. Pre detination and stuff like that?

I always read. Its fundemental(spell check)

detonation is premature explosion....(fuel exploding before it should) and is not good...and no, a supercharger is going to put MORE stress on your belt system due to the tension on pulleys and the rest of the belt system. and no, really power from a turbo is free, your car has to get rid of the exhaust gasses, so by making it charge then intake air by using a compressor (turbo) along the way gives you FREE power. AND

Sov is turbo jesus! i wish i could spend a day in the shop with him, i bet i would learn SOOO much in just that short period of time...hell, ive learned so much from him already.

With a correctly made equal length manifold and correctly sized turbo you will experience extremely little backpressure. Either way, you're not literally using the engine's torque to make power, the only thing you may do is decrease N/A performance due to the turbo being an exhaust restriction.

Detonation is detonation, there is no "type" persay. Turtle pretty much got it.

Haha, Turtle, when I first started working on cars I knew... well... nothing! Lol, just takes a lot of reading and a lot of toying with things.

I see. But i still think in the long run you are goin to go into a lot more repairs with a turbo than a supercharger given that they are both tuned correctly.Belts and pulleys are pretty much cheap and i could prob make one in my engineering class using autocad or some similar software.It just seems to make more sense to me that it would be easier to repair lol. Some1 with a SC help me out here lol other wise i am goin to have to dig up some info and i feel lazy.

^ When i first got it tuned, i experienced fighting not going into the other lane. Its real, not just a figment of the imagination, you have to fight the wheel somtimes depending how hard you get on it.

I had an SC, intake temps were through the roof and the car literally made no power. 146whp and like 118wtq. Centrifugal isn't quite as bad with an aftercooler, but it still just isn't going to make a lot of power. Turbochargers make more power, but as long as you're built for it you will last the same amount of time as a supercharger. As far as I'm concerned, there is less to worry about with the turbo than the supercharger, especially a centrifugal one (hell, centrifugal is a friggen belt driven turbo setup!).

If you want to make power, turbo is the way to go. It's also cheaper, look at what you're paying when you could put together a turbo setup that will make more power for less money.

I don't know, turbo to me is a win win when it comes to Honda's.
