Add Turbo to a base Sky

[skyhigh22]

Can anyone tell me if they added a turbo kit to there base sky,how do you like it ? was it worth doing it? one of my pals said that there is a chip you can add and it does the same thing,l don't know how true that is!!!!

I have a RL, so can't speak first hand about the NA and turbo packages. As for a "chip" that does the same thing...well...not exactly. These cars (the NA and the RL) are tuned/designed conservatively by GM. Aftermarket tuners can "tune" the ECM, add some more efficient parts (intercoolers, exhausts, CAIs), to bring out more power. Not as much as a turbo, but gains of 30 to 40 HP have been advertised.

Check out the supporting vendor sections. There are several supporting vendors who offer various stages of tuning, from the +30HP ECM tunes all the way up to +200HP (that's in addition to the stock 177!) turbo kits.

Thanks for the info,will do some homework

Check out DDMWorks.com

Look into their stage I and stage II superchargers. They're amazing!! Feels like a v8 swap.

Well, I have the Hahn Stage 2 with the Magnaflow exhaust and I really love the extra power. I am going to upgrade to a Stage 3 someday soon. The difference between the 2.4 stock vs the Hahn turbo is crazy! It is going into Hahn this week for a little power upgrade. Can't wait to get it back!!!

Now l'am really getting fired up to put one in,let me know how yours turns out...and thanks for the info.....cheers

Think long and hard before you do it....

I have the Hahn stage 2 setup, and to be honest, on 94 octane the thing runs ok at best. I recently added a water/meth injection kit, and I'l say it runs twice as good now. There are still some issues, and i'd be interested to see how other peoples stage 2 setups run for them.

There is no question, under WOT the thing screams, and is far faster than the stock redlines, but reliability seems to be an issue.

I'm on motor #2.

Therefore I'd look into DDM

I have now had 2 Hahn equipped cars and both ran flawlessly. I have the Stage IV now with my new car and it has the upgraded valvetrain. The car screams now and I love it. One of the biggest issues I see is the Installation. Make sure you get a reputable shop to do the install if you are not doing it yourself.

[SolScuba]

IMO I think any custom setup needs a custom tune too. JMHO

[jchao]

I love mine. It still has a hesitation at idle.
I am also going to upgrade to a stage III soon.
Now that I have 315 horse power I want 354.....

I have the DDM stage II intercooled Supercharger kit and it really makes a huge difference in power, it rips. It also delivers good mileage and excellent low RPM torque and HP, like a V8.
My recommendation to anyone considering a Turbo or Supercharger kit is that if you are not mechanically inclined and willing to do a little tinkering, you should consider trading for a Redline.
We're waiting on some improvements to improve "driveability". Would I do it again?...probably, the jury is still out. DDM is testing an upgrade that should bring driveability back to stock levels. They are a good company that has been excellent to work with, and they are addressing this issue.
The stock Sky clutch is at its limit with the stage II kit. If I want to, I could cook it. Driven responsibly, it should last OK. The tires seem to be wearing a little more...

I'm giving very serious consideration to the DDM Supercharger. This is the first I've heard of "driveability" issues. Can you please be more specific?

Wait a couple more weeks and it should all be figured out. If you don't feather things good right now it has a tendency to stall out during deceleration. They are switching the location of the MAF sensor which should be a cure-all. They have a few beta testers and they will fix it. That I can guarantee!!

Jeff, Like SolScuba said, there is a tendency for RPMs to drop at idle sometimes stalling before it recovers. There is also some hestitation between shifting gears.This appeared on stage II because of the added volume of the Intercooler. I too believe the relocation of the MAF sensor is going to solve this issue. Wait a couple of weeks and we will all know. DDM has been diligently working to correct this and they are excellent to work with. My car is fun to drive now, and the ECM has learned to correct for some of this. It is more of a nuisance, and my wife is not comfortable with it. I have learned to drive around it for now.

It is nice to see some of the little problems coming out.It helps me decide whether to go turbo or supercharger, or just upgrade to the redline. As it stands right now I'm leaning turbo, only because I would have to buy a new header if I went supercharger , just a matter of economics.

Hi I went to and Eco-tech rally last month and talked with a guy that put a supercharger on his 2.4 cobalt. He had the same problem. He repaired the problem by installing MAF on the #1 intake runner about 1.5 inches from the head. That took care of the lag time,rpm drop, and stalling. Since it is a front wheel drive, I wouldn't think there would be any different s. I hope this helps? ED

That's interesting installing it in an intake runner.
Early test reports are very promising with relocating the MAF on the outlet of the Intercooler close to the engine. This approach measures all the air going to the engine, not just one cylinder, like stock.
Thanks for the feedback.

I think it's a matter of WHERE you want the power.

Supercharger is instaneous and low, then tops out
Turbo's need to Spool a bit but then the power keeps coming till redline.

So the best fit, IMHO, is the one that matches your driving style. You can look at the Dyno Charts and think about where you hang out RPM wise.

All of my forced induction vehicles previous to the Redline have been supercharged and I also own a Buell Firebolt, So I have been used to the Instant On power vs the way a Turbo hits it's power.

That said, In looking at the Redline, and how it's power curve was, I liked it and after driving it, I was hooked.

What would really help is if you could somehow test drive or get a ride in a sky with 1 of each. Then you could get a seat of pants feel.
The one that makes you smile widest is the winner.

Whatever you do get all the facts! If you want the big power go turbo or supercharger, want to add a few horses, go tune with a few mods. I think the key here is finding the company and the person, (persons) who will work with you after the sale. Select a company with a "network" of certified installers (mechanics with custom application capabilities)..... I have been told Hahn has a listing of capable installers located around the nation which is a good thing for those who can't do the install themselves!

I like how the 'improvement' to the supercharger kits is to imitate what we've done with our turbosystems from the beginning insofar as MAF location. Hey, if it works, copy it!
