Well, I was over at my sister's house the other day when her friend came by and noticed that I have a 2k2 EX with some mods. He asked me what I planned on doing with it. I told him that I would prefer to do a custom supercharger from a shop and he just laughed at me. He told me that I wasnt going to get the boost that I needed from it and to go turbo. Well I told him that I didn't want to mess with turbo (turbo controllers, timers, waiting for the turbo to spool down before I can drive it again, etc.) Just dont want to deal with all of the maintenace that I have heard about from friends. (Hey I'm very lazy) So anyways, he fires back and says that what all i said wasnt true about turbos. Now this guy is a mechanic for a ford dealership, and obviously I'm not a mechanic so I listen to what he has to say. He goes on to say how great turbos are, AND if the boost that you get from turbo isn't what youre looking for, you can just add another turbo to make it a twin turbo. I stop him right there and say that I thought twin turbo wasnt necessarily good for a 4 cylinder engine because by the time you get those turbos spooled up, the other car is in the next county. He insists what I am saying is rubbish. He then highly suggests for me to get a custom twin turbo kit done on my car and that I wont be disappointed. Now what I ask of you people is that; is the mechanic who works on fords correct, or is the kid who did half of his homework right? Thanks for the input in advance.

I want a supercharger too and not a turbo. i think he just wanted to tell someone else how to spend all of their hard earned money. twin turbos will get very expensive.

LexBoy

i got everything down until u mentioned spooling

i mean what is that???? to let the turbo warm up and then you can use it??????

is that it????

DC5@EM2

No, what I have been told is that the reason why you dont have an instant boost with turbos is because they have to spool up or get enough revolutions in order for the turbo to be useful. Thats the reason why theres "turbo lag" because the turbo has spooled up yet and theres no boost. Well, if on wrong on anything, please let me know. I hate going around and not know what I am talking about, lol.

Venomcivic:: You are right. The main down flaw of turbos is the turbo-lag. This is the very brief amount of time when you don't have the boost. At this time, the engine is practically naturally aspirated. Supers have to lag time cause they are driven directly by the engine.

DC5@EM2

well what about the twin turbo statement? Is it worth it to twin turbo 4 cylinder engine cars or am I right about that too?

2k1Vtecivic

were can i get a custom super charger installed
i dint know there is such a thing besided jakson r and vortech applicatings for honda engines

NeoMagus

Hmmmm its a Ford Mechanic most Ford ppl spit BS. [IMG]i/expressions/face-icon-small-puke.gif[/IMG] Get your custom supercharger. Unless you puttin Nitrous in with your Twin Turbo to eliminate the lag, its almost not worth it.

tsunamisplash

how is nitrous any help to a turbo? isn't nitrous is just as useless as a turbo off the line? i most likely am wrong, but isn't it a bad idea to 'press the button' or 'flip the switch' at low rpms and especially in 1st gear?

NeoMagus

Q:"Are there benefits to using Nitrous with a turbo or supercharger app?"

A:"Yes! Turbo lag is completely eliminated. Turbo and superchargers compress incoming air, thus heating it. Nitrous adds an intercooling effect (75deg or more) and boost is usually increased as well adding even more power"

Straight from a NOS booklet

tsunamisplash

alright.. i guess i was wrong, but i still believe that using nitrous oxide off the line is a dumb thing to do, especially for an inexperienced driver.

Superchargers are fine if all you want is have some extra power going to and from work/school/grocery store. Turbos do have lag, but bottom line - they will produce more power at a given boost level than any supercharger. Plus they are upgradeable by adding a larger turbo, engine modifications to support more boost, etc. The only upgrade I can think of with a supercharger is adding an intercooler.

htowncivicEX

As far as using NOS with a turbo, you are going to seriously mess up your engine unless your engine has been rebuilt to handle that kind of pressure.

The twin turbo thing is about the larger turbo spooling up at higher rpm's and the smaller turbo spooling up at lower rpm's. They're different size turbo's that will give you more of a consistant power increase.

2k1Vtecivic

i have never heard of custom superchargers

OK, here is a question. Turbos do have to spool up and that's no problem because it's not that long before the turbo provides the boost - but is there anything else that has to be done after the fact - does the turbo need time to cool down or anything like that?

Also, if I were to get a turbo, should I also get an oil cooler so that the oil that's cooling the tubro AND the engine can be cooled itself. Would I need oil changes more often.

NeoMagus

you def gotta change the oil more and run higher octane fuel...my friend runs a 97 Civic EX with the T3/T4 turbo and he has to change his oil every 2,500 miles as well as plunk in the 91 octane

Superchargers are also upgradable!!!!

Check this out.

Jimmy24

That's good stuff 2k2civic, but I'll wait till somebody has it installed in a 2k1civic and see what happens in 6 months, If is good, I would buy it!

JesterSpaceCowboy

my $0.02..

superchargers give power sooner because they are driven by the engine, but that extra psi at lower rpm will be harder on the engine

turbos do have some lag because they are driven by the exhaust, but they arnt as hard on the engine at low rpm

if you want to drag... go supercharger
if you just want to blow by people on the fly... turbos your answer

Dakker

Im not a mechanic but I am taking auto classes at my local college, and from what I've learned about turbos, the only way to get a twin turbo set up is with a v6 or larger engine. here is why:

Turbos get their power from spent exhaust gases exiting the engine, they are hooked onto the single pipe part of the exhaust manifold. Well in our cars we only have one of these, there for it wouldn't work having two turbos set up becuase one would have to be after the other right? The only reason this works is that v6 and larger engines have 2 headers.

Someone please tell me if im wrong because i'm basing this on what i know so far[IMG]i/expressions/face-icon-small-frown.gif[/IMG]

Jimmy24

Hey Dakker, as far as I know, that's the way it is!, that's my understanding too, but...
Some people do some crazy sh@t!

civicman10

Even though turbo's and supercharger's aren't out yet for our cars, can anyone estimate as to how much of a HP gain we'll be getting with either?

IonRays

One word........................

<<<<<< I N T E R C E P T O R >>>>>>>>>>>>&g t;

if you dont know what this means..This car was in the
movie called "WRATH". And why I bring this up is
becuase the INTERCEPTOR was production car with
((TwinTurbo T28/ Ford inline-4 block /Cosworth head)) and
rated 400hp output. Whats amazing about it is the "200hp per liter"
This was in the 80`s. before any turbo civic roaming the 1/4 or street!



now thats a motor i want to drop on my civic [IMG]i/expressions/face-icon-small-wink.gif[/IMG]

IonRays

with an eaton SC M14 its about 30hp-50hp gain depend on boost, i think for turbos it depends on the size and boost

that should make my nonvtec very happy, also me!300hp+

ahem, im okay.



Also Dakker Inline-6 has twinturbos on the same side ,each turbo is powering 3-cylinders each. like the supra&skyline.
Its the same as goes for the v6 twinturbos but a single tubro for 4-bangers is more practical

Dakker is right about this--and about the "I N T E R C E P T O R"--that engine is so freakin "out there" that unless u have more money than the value of ur car to put into your engine don't even mention it.
