Awesome Zack, way to show up out of no where and bust a head.

Hmmmm maybe I can use the blower to help throw the exhaust at the rear mount turbo... and do my own unique twincharge.... Thanks for the idea all

 

why? air to water is much more efficient? that's retarded. For the alfa romeo, it makes sense, there isn't room fo an intake manifold and intercooler system there, so the air to air makes sense. On a cobalt, it's just stupid.


As for the rear mount turbo, can you say 0 backpressure? They spool quick and make good numbers. You guys that are bashing don't know what you are talking about. What a bunch of tools.

 

first off when u have a boost lag like u would from a secondary turbo there would be not as much of a need for traction as u might think ... by the time u get the power to the motor u should already be off the line and rooling( if ur not than u just SUCK!) but no matter what the numbers are its all about the t/q curve over everything...

if i have 120 hp/tq untill 3500 rpm and then i get 400hp/tq ( i know crazy numbers just example) by the time i am at 3500 rpm i should be off the line and rooling ready to shift... the boost lag might not be that great but they would be a nice thing for a ss/sc car because instead of having all the power at the begining u could slowly increase it as u progress in rpm's twords higher boost in the end... story short it will work .. prob just cheaper to buy a normal manifold and bolt a turbo on it and run the piping... simpiler, easier, cheaper, easier to tune( not boost all at 1 time) might even be harder to tune for not sure.

 

where is the dyno sheet for that guy with the STS cobalt....

cause 258whp doesnt sound that great. especially when i know people who are pulling close to that from their LSJ's

i really hope that he didnt sts an LSJ and ONLY make that much power.

 

that was a 2.2L L61

 

then hmmm.

still would rather go with a Heaton

 

HAHAHA are you refering to the thread I think youre refering to??? The kid that thought the whole engine went in reverse when you put the transmission into reverse. That was right around the time I joined the site....that was an Epic thread for sure.

 

lol yeah he was talking about that thread.

i think that was just some guy who was jerking our chains, cause if you looked at his other threads they were all about intelligent stuff that proved he knew something about the way things work. lol.

engine going in reverse. i have that entire thread printed out and sitting on my desk at work for when i need some lulz.

 

I had a sts turbo kit on my 350z and I was hitting boost by 2600rpm they are awesome kits and you generally only loose about a pound of boost thru the piping so you just crank it up another pound. One other thing is that STS has installed thier kits in a cobalt and works just fine the only issue youd run into is tuning.

 

CLEAR! Wohoo...you just revived a dead thread!

Sorry, I had to

 

its amazing how many of the members on this site are uneducated. rear mount is not a new idea...it works and it works well.

 

Im just amazed with all the money that guy spent on the turbo he went with a set of cheap ass nankang tires.....

 

What about doing a twin turbo setup. I larger trim in the rear, and keeping the K04 up front. might be a paint in the ****, but should make nice numbers if properly tuned.

 

I think it would work well to put the turbo in the back...

...along with the entire engine and trans.

 

LoL .. Make a kit!

 

So much fail in this thread. Even the guy that had some turbo knowledge was wrong about a lot of things in reference to remote mount kits. Everyone else was just mindlessly regurgitating BS.

 

x2. welcome to cobaltss.net. Dont come here with high expectations unless you wanna dick around the lounge, If you expect the majority of people to have no idea what there talking about, you wont be dissapointed.

 

for those people who say that 20 feet of charge piping will take for ever to pressurize.... Why does the charge piping have to be 2.5" diameter? why not 2.0"? I think this idea is cool, just need to figure out the optimum charge piping size to make it work.

 

That was my doing , still my most successful (as in views/posts) thing I've done on the internet. Coworker and I were bored at work one day and decided to see if we could stir the hornets nest. One of the best parts is I hadn't seen one friend in a while and next time I saw him out of the blue he asked if I was the one that started it. He wasn't a member here or anything, he just saw the thread from a Ford forum and that the OP (myself) had a Red 08SS and just figured it was my doing.

On the subject though STS turbo's work and in many circumstances put out high peak #s and have a better torque band than low psi centrifugal supercharger options (for f-bodies that is). Although you can never get around the fact that the amount of work that you can extract out of a fluid stream is dependent on the change of enthalpy of the fluid. If a turbine has a set efficiency and you start with lower enthalpy (aka lower temperature & pressure), you will get less work out of the fluid. The further the turbo from the combustion source the lower the enthalpy of the fluid will be. (by fluid I mean air, in thermodynamics fluid can mean a gas or liquid)

edit: didn't notice this was an old thread

 

SMG is making a kit as well for the cobalt...wow such horrible knowledge spread by members :/ holy late post batman
