 turbo vs supercharge?

I have bought 4AGZE, now I am deciding whether to stay with supercharge or go the trubocharge. The engine is for TA22 for use on street and beating HSV idiots. What rear wheel power can you get on either and still be streetable?

I'm pretty sure this has been discussed before at length.
Take a search of the forums, and it should be able to answer most of the basic questions!

with a stocky supecharge you will be able to keep up with the hsv boys except the gen3s. want to catch them and beat them be prepared to do more work to the supercharged motor more or go the turbo route

Turbos are between 70-80% efficient whilst superchargers are around 40-60%. Thats all i need to say.

Yeh turbos are more efficient.. BUT WHERE?
Higher in the rev range.. FACT!..
I have a GZE and i am seriously contemplating the turbo route.. BUT!.. I love the car for its low down power.. i can mash the pedal at 1000rpm and i have boost.. around the streets i think a well tuned GZE would chop a 4agte..
If your a straight line man.. and thats all you wanna do... GTE.. if you like to rip around corners and ALLWAYS!!! (read paul) ALLWAYS have boost.. then go the S/C route.. with a big pulley running 13-15psi they go quite well.
And thats all i have to say....

If you were going to rip around corners, why the hell would you be mashing the pedal at 1000rpm? To be quite frank, you talk about a properly tuned S/C engine, have you actually driven a properly tuned turbo engine? Even my old Starion with its shitty old 7.6:1 compression had full boost at around 2000rpm and was hauling arse up to its redline...my mates Silvia, now thats awesome...

I have read that the superchargers that you can get about a maximum of 200hp aftermods and you have low down torque. What power are you looking at for turbo?? Is there a cap on the amount of boost for the engine (i will be using aftermarket ecu)?

Is it true that you can hook a switch up to the s/c and turn it off and on??

yea you can, but that is pointless since the 4agze (depending on which gen) will be running between 7 and 7.9 comp.. which is crap for a n/a engine so you will be uysing alot of fuel and going no where fast, thats why the S/C comes with a clutch so it turns off when you dont need it..

what would happen if you had a supercharger and a turbo then you should have good all round power 
i've heard it being done to boats but never cars.
and yes i think you can turn off supercharges as it has some kind of clutch in the pully but why would you bother turning it off?

yeh thats great... ive been in (ex) micks spinter which my freind owns now.. and its got shitloads more laaaaag but hammers up top.. u talk about your turbo having boost at 2000rpm.. how much boost did u have?
im not saying s/c is better.. in some ways i want to turbo my car... but i honestly dont think the car would be as "drivable" with a turbo.
dont let this go flame.. cause to be honest i dont give a shit!

Have a switch so that the bombadores think they have a chance then at the next set of lights waste their sorry ass.
There was a s/c + turboed ae92 red corolla in hot4s a couple of years ago...that would be a bitch to tune.

Myself and a mate did a twin charge setup a while ago and it worked alright but was a total waste of money! It was just a total bitch to setup and my opinion is it just isn't worth it!
Just get a good turbo setup!
The twin charge setup was good for when people looked at it and said "what are all those pipes for"

Corvid, when you've got 3litres of capacity and shit loads of torque you dont need lots of boost as you do with a 1.6L. There's plenty of power off boost let alone 300rwhp on boost.

Yeh... i agree paul you monkey!!
my point is... with 1.6.. do you know how much lag you have with an engine of that capacity? Admittadly its not that much but its enough to piss me off.. if i had a 7m in my mr2 id be fine! But ive got half the capacity of that thing.. so a 1.6l motor with 8:1 compression off boost is gonna be a PIG!..

This is what I know about the Turbo vs Supercharger war....
Turbo
+ High end power
+ more room for further mods
+ no loss due to strain on engine
- can suffer from off boost lag
- stereotyped due to dicks and their megaphone BOV's.
Supercharger
+ Power gain throughout Rev Range
- Engine driven via belt so they do put load on the engine (they make more power they loose though but not as efficiently as a turbo)
+ cool whinning noise that I really like!
Correct me if I'm wrong?

There are actually superchargers that produce more boost with more revs.
But these feel even laggier than turbos do...
The supercharger sound is cool, but I reckon turbos sound better... Many people comment on how my car sounds like a plane taking off.
Of course, if your supercharger/turbo is making noise, it's a sign that it's inefficient, but still.... Love the sound.

I wonder if anyone has though about designing a geared supercharger  It could be based around one of those high PSI units and at low rpm it could be geared low and at high rpm it could be geared high to stop over spinning!
Food for thought

AE82Twincam/Andrew - I think you'll find the CR is 8.0:1 and 8.9:1 for the 4AGZE's
GIN51E - TwinCharging (turbo + SC) is an option however the complexity and cost is usually prohibitive for the performance gains.
I have a 4AGZE (MAP/DLI) but am going turbo. Mind you I have been really happy with the Z plus larger pulley. The turbo choice is what makes the difference in drivability but your the one who has to decide what sort of drivability your after. Find someone with both (difficult to find a turbo I know) and go for a drive.
I do have an SC14 and all the bits to fit to my motor but I don't think I will put it on. As is documented in another topic, the SC14 fits in an AE86 but FWD's have space problems.
