i wanna see votes who choose turbo or supercharger? what do you think is better?:naughty:

Right, lol. The turbo lag makes up for its-self with the sweet BOV sound.
Superchargers are an extra load on the engine, but since they are directly driven, there is no lag.

On the lag issue it depends on what sort of blower you get. A PD blower (roots style) will give you insta-boost and axle snapping torque but a centrifugal blower like a vortech makes boost only at higher RPMs.

Blowers are cheaper and far easier to install but they make a lot more noise and don't make as much power. Given the available size with the V6 there a blower is where I'd go. I really wish there was an option for a roots blower as I think it would be a nice setup.

I have written countless posts on this in various threads, as someone who has supercharged the 6G75. there are eccentracies with the set-up on the 4g that would probably not make it as hard to do on another car.

that being said it comes down to this, as far as for the 4g:
the Turbo (assuming all is done right, tune, supporting parts, etc.) will make more power in general, and the BOV is of course very cool. HOWEVER, for our cars specifically there is not a good pre made package - so you are stuck doing it all yourself - not an easy task for a novice weekend mechanic. they are probably slightly more complex, require intercooling of some kind, and all of this makes getting a perfectly tuned and working safely turbo set up a tall order on the 4g, especially for the GT. The two GS' that have turbos that I know of, (elemenopee & b-shue) both have problems that have them sidelined at the moment. HorseEater has a sweet twin turbo set up on the GT, BUT also has problems w/ the tune (horse correct me if I'm wrong) and needing other parts to be upgraded to get it REALLY producing the power it could/should. One of these issues on our car is valve float.

as for the supercharger - at least there is a specific package out there for us, and yes I know RIPP doesn't make it anymore - BUT you could probably find a used mounting bracket and drive shaft (the two main things you'll need to get the blower working) or even maybe get RIPP to sell you them. the blower is just Vortech, whatever trim you want. so someone wanting a blower could get one, put it on there and make it work, same as trying the turbo. STill need supporting parts and a good tune.

BOTH have struggled with the fiesty ECU of this car - the AEM F/IC will let you overcome some of the issues, and at least deliver enough fuel. If you are really smart you could figure out how to use the o2 manipulation offered by the device, to get some of the o2 codes to go away. To me, though, the sound of the SC is off the hook. It's not as loud and a little more subtle, but it sounds like a damn UFO coming down the street. there are 2 different cool whines the unit makes depending on what RPM you are at, and it's sweet as hell when you hear the RIPP by-pass valve open/close. (sounds like a sword being unsheathed). I love mine to death, and feel it defines my car. Even not going into boost, just pushing that extra air in there is awesome and adds power every single time you press the pedal down. A turbo will lag a bit before it starts making good power for you. the other thing to do is get the reflash from Hackish to make this work. I personally have spend THOUSANDS on electronics/tuning trying to make mine run perfect and have not yet had success - BUT I am about ready to do the reflash which SHOULD clear all this up once and for all.

VALVE FLOAT will kill both set ups going above 7 lbs or so. The only way to fight this is to spend $$$ at deltacams or somewhere similar to get your valves upgraded to oversized and hopefully a 3-angle valve job and cam regrinds/welds. Very expensive, but no doubt worth it if you are serious about getting up into the 10 - 15 lbs of boost on our high-compression engines.

OTHER PARTS & UPGRADES are FOR SURE needed for both - like suspension, tires, clutch, LSD, headers / turbo manifold, high quality exhaust system, engine bushings, suspension bushings, strut bars and sway upgrades, intercooling (via meth injection for SC and a FMI for a turbo).

well, I was trying to make this a simple post, but wrote war and peace instead. there's probably a lot more to be said, but I'll leave it there for now.

Im wanting to get the most hp out of my car, i have a 2007 eclipse gt, its got an exhaust and injen intake on it so far and im planing on headers too, but after that im wanting to look into more performance mods and ive been either thinkin bout turbocharging it or supercharging it. ive read that they have pros and cons to each but which one would give me more horsepower and also not kill me pricewise??

It'd be the cheaper, more restrictive buy, yes. You can run a stage 1 pulley (5 or so psi, maybe 40 whp added) with it without many additional mods. To really get the advantage of an FI setup though, you want to do it right. Get an intake, headers, and exhaust first. Then get a tune, then start building your internals so they can handle the boost.

Do your research :) The Google search at the top of the page will help you find threads from all kinds of members who have been there and done that. If you want to go with either SC or Turbo, you really have to do it right or you will be looking at a blown engine.

alright thanks man, I was planning on doing all of this after a good while of doing mods to my car. I already have a injen intake on my car as well as a catback exhaust. im looking into doing a bigger throttle body as well as headers for a little more horsepower and more performance. But thanks for the advice i will really start looking into it to see what all i can do to it.

Do both.... Many large yachts have both and its with a purpose!

At lower rpm you have the supercharger to give you boost, but once you get the turbo spoiling the clutch on the supercharger engases freeing it from the pulling and then you are boosted by turbo at higher rpms.

This way you get the most efficient low end torque and power while getting the most efficient higher end boost provided by a turbo.

Lol
