I was just reading the "twincharging is here" post and i was just curious how many of you planned to switch your Supercharger for a turbo Charger?

I thought the M62 was a pretty decent supercharger? Why would people want to go TC? More top end? Couldnt you just port the supercharger for that?

newbie questions i know... but please enlighten me.

 

Definately turbo for me man! You can go full turbo now! PM me if you need details on how to do it, I dont want to post it here cuz its all hush hush now.

 

bump... i dont want to go turbo i enjoy having a supercharger its different.

 

I'll go turbo when hahn releases a kit and I have money.

 

I want to go twincharged later on when I have enough to get another car because I want a "SUPERTURBO" but I dont want my daily driver to be 300 hp or so gas would be a sonamabitche its already draining my wallet with just an intake.

 

If the car wasn't FWD I'd get a turbo but I don't feel like modding a FWD car that hardcore. Evo is where it's at.

 

hey how do you go all turbo i had a gtp and i traded it in im sick of these eatons they suck after a while , i want to get a turbo how much they running ps my cobalt is brand new and STOCK

 

hey guys, just keep in mind, that once you take the supercharger off this car, you have about 120 hp... if you pay 4,000 for a turbocharger that adds maybe 100 hp, you're 4 grand in the hole and at the same exact power level you were at... just a thought...

 

It's a swap not a removal, at no point would I run the car without either the SC or a TC. And given the same boost level and tune the TC should make more power, no parasitic drain. The crank doesn't have to spin the SC anymore. And besides, I just like turbos. I bought the car for the internals. A factory built F/I car is always much easier to mod than one you have to build up.

 

I agree here, alot of cars of there are turbo. time for something different. im tired of hearing the sound of a turbo. the sound of a supercharger is much better and creates about the same hp if not more.

 

alls i'm sayin is that 4,000 for a turbo to make the same or SLIGHTLY more power than you're making stock is rediculous in my opinion...

 

just stickin to the SC for me!

 

The ppl that like their SC for being different are fooling urselves, if your happy with it fine. Theres a reason so many cars are turboed because they deliever greater performance hp wise. If we had a bigger engine that we could mount a larger SC would be coo (GTP's and Cobra's) but with the 2.0L and M62 there is very limited potenital. I knew this the day I bought the car. Being different (non mainstream) in the automotive world means that it doesn't work as well as something else out there.

Entitled to your opinion! But turbo IMO sounds way better. If SC produced more HP than a turbo every car would have them. The reason turbos are so popular are their potential. If you took 5 random cars and put SC's on them and took another set of the 5 and put Turbos on them im guessing the turboed cars would destroy the SCed ones.

Not to mention one thing about turbo's I really like is boost controllers. Being able to drive around at 5 PSI for daily driving and at the flick of a switch be boosting 25 PSI.

But I have to admit the throttle response of a SC car is awesome!

 

This is EXACTLY why i want to go turbo...and it has the potential to produce more power, and if properly tuned, will have very little turbo lag.

 

That depends on which kit you buy. Then again, you have to pay to play. These are all things to take into account as to whether the individual will want to make the investment. Personally when I have the money I will make the investment. Like I said, I've always wanted a turbo.

 

i guess, but 4000 into a turbo would b e better spent building up the engine. if you take 2 stock SS/sc and put 4000 into 1 to turbo it and 4000 in the other to build up the sc . the SC one would be WAY faster.

 

That should about sum it up.

 

Me = Turbo import fan that bought a SC domestic Turbo here I come.

My Cobalt SS Turbo will look good next to my Evo X

 

Pete....Pete relax their buddy!! Its o.k to love a turbo more then a supercharger. I for one used to have a highly modded turbo Eclipse, I modded the car to 400HP. I did all the work myself, even rebuilt the engine myself. But ever since I got my cobalt and started to mod it I can tell you right now am never going turbo again. Why you ask? Because they are extremely high maintenance and are just not reliable. A supercharger like the EATON is used on high end cars like the mercedez Kompressor, Jaquars...its about power with reliability. Thats just me doe, I love superchargers, but their are pros and cons to every setup: nitrous, turbos, big displacements, superchargers..etc...I would be writing until tomorow morning to describe to you the pros and cons and why I like superchargers more. But at the end its whatever you like best


BTW: You can use a Boost controller on your cobalt. Did you know that? Very easy, I am doing it next week on my car. First thing you do..you install a 2.6" pr 2.5 pulley (bypassing the boost solenoid you can boost to over 20+ PSI very quickly). So you use the boost controller to control the boost to whatever you desire. I will keep mine at around 16-17PSI for now.
Not sure if you understand my very quick explanation but look for my review next week with Picture on how to do it and how it works...this Ideal was introduced to us by JMC007 quit a while ago.

 

I'm guessing but if the 2.0T is making 260hp stock then I'm sure the one coming out for us will be bigger and will make more power. Also I'm sure that the people that get the turbo will be able to turn up the boost for more power.

 

yea but the sky redline has a 2.0L VVT ( variable valve timing) engine. so im guessing that the engine can take a little more boot then our stock engine...anyone know this????

 

I smell a shop build off....

 

I think this might answer a few questions.

"The New 2.0-Liter Turbo Engine

The heart of the Solstice GXP is the Ecotec 2.0-liter turbo engine, GM’s first direct injection offering in North America. It produces 260 horsepower and 260 lb-ft of torque, making it GM’s highest specific output engine ever, at 2.1 horsepower per cubic inch of displacement (130 bhp per liter), and the most powerful production engine in the Ecotec family.

A dual-scroll turbocharger with a lightweight turbine provides nearly instant power, and an air-to-air intercooling system boosts the turbo’s performance by reducing inlet temperatures. Dual cam phasing complements the turbocharging system by optimizing valve timing at lower rpm for best turbo response and quick access to engine torque.

Direct injection technology helps the Ecotec engine produce more power while maintaining the lower fuel consumption of a small displacement port-injected engine.

With direct injection, fuel is delivered directly to the combustion chamber to create a more complete burn of the air/fuel mixture. Less fuel is required to produce the equivalent horsepower, especially at normal cruising speeds, of a conventional port-injection combustion system."

I just gotta chime in with one thing about the LSJ verses the 2.0l Turbo. Granted the 2.0l Turbo has the flattest torque curve I have ever seen, but making it that flat in great part comes from the VVT & DI with very careful tuning.

Now if the 18% loss for the cobalt drive train is correct, then the LSJ is producing between 250 & 260 crank HP and between 230 & 235 crank ft/lb of torque. Or another way to look at it would be the 2.0l Turbo producing between 210 & 215 HP and torque at the wheels.

If the LSJ gen 2 was given VVT and DI with tuning to cut down on the torque lose at higher rpms, I'm betting they could hit 270 crank HP @ 6.5k rpms. That would allow stage 1 to hit nearly 300 crank HP @ 7k rpms.

Of course, all these numbers are based on the 18% drivetrain loss given by GM. If the loss is lower then the LSJ comes off slightly weaker and if the loss is higher the LSJ comes off slightly stronger.

Cheers

 

why would any company release a turbo kit that yeilds almost the same horsepower as stock. the reason why that thought is a bit ridiculous is fairly self explanitory.

.... guys... the turbo kit is going to be highhhhh hp numbers. if it wasnt, then ppl could save a few grand and go with intense. plus, the potential will be much greater (also consider that the s/c on the cobalt is STOCK, the turbo is aftermarket). i now feel stupid for actually having to explain this :P

i still havent decided if i am going to go turbo or not..... time will tell
