So I was on a website and someone said that in 2008 they heard the Cobalt is going to be switching to a Turbo and they are going to be running the same setup as the turbo solstice with 260 hp, anyone know anything or heard about this?

 

Yeah we've heard,and by the time they come out we'll have modded ours to be way faster than those.

 

Some magazine had an article claiming that. Someone brought it up in a thread a few weeks ago. While it is possible, it is important to note that nothing official has come from GM (nor will for some time). Not saying it isn't happening, but just that it is not for sure yet.

I will be dissapointed if they do go that route. I was hoping that they would just add VVT and direct injection to the supercharged engine, but I guess that won't happen.

 

yea its very possible....much more effective..not sure if its more cost effective...most will say it will never happen...im undecided cuz there are currently other cars gm turbos...and i think they are slowly doing away with the superchargers...so i guess we'll just have to see.....

 

I was just thinking......If the tubo 2.0 really makes that amount of hp. at the fly like gm claims and it's not underated, than technically it's only making about 10-15hp more than ours stock. Cause every one already knows were on average dynoing in at 215-220 to the wheels stock, given a 15% loss, were right there with the turbo 2.0. Maybe that motor isn't under rated, and gm is doing it from a business stand point, cause a 55hp incresse does sound really good on paper. And the average persone not knowing what the sc 2.0 are really making, they will go out and buy it. One whay to find out if it's under rated sooner than 2008 is just to wait for the solstice gxp to come out and see what they are dynoing in at.

 

A FWD car really only loses 10% power or less. The engine connects straight to the transmission. There are no big heavy driveshafts running power to the wheels like in a RWD car with about 15 % power loss. Dynoing the solstice would be pointless, because it would experience more power loss than a Cobalt with the same engine.

At 205 crank HP, we should make about 184.5 wheel HP with 10% power loss.

240 crank HP would make about 216 HP at the wheels with a 10 % loss of power.

 

i would actually prefer a turbo engine to be honest. I was actually thrilled to see the Solstice is being released with an upcoming turbo engine. I've had two turbo Fords and two Turbo Chryslers and feel that turbocharging is way more efficient than the blower. To a certain extent, even durability questions are pretty much an unissue.

they need to do something big to compete with dodges new monster.... 300 hp awd dodge caliber srt-4

 

The new SRT-4 isn't AWD. Only the R/T model is.

 

thats too bad awd would put the caliber in the ranks of an STI or EVO... its still a beast of a car.... if chevy will have a new cobalt, and dodge the caliber, hondas civic SI and RSX typeS, and lastly subarus wrx, what about poor little ford, their little SVT fuckus isn't gonna hold up what do you think ford is gonna do about it? they need to step up the game....

 

the svt focus got axed two years ago bro, ford wont have anything for awhile.

 

and the rsx-s is gone after this year. the civic si took over it's spot, and acura is killing it to move the brand upscale as a bmw/lexus fighter.

 

The articles have been in GM high tech magazine the latest one is in the july issue. They are also running a direct injection system on them as well.

 

I was at the mall yesterday and GM had a display of a few cars including a red SS/SC. I talked to the rep that was there who actually knew what he was talking about.

He informed me that yes they are talking about a 2008 turbo SS/SC with the same engine that is in the 2.4L turbo solstice. Apparently this engine is more fuel efficient than a supercharged motor.

Since still 1 year away we will just have to see what GM has in store.

 

For the cobalt SS , GM claims a 17% drivetrain loss

 

ALL WHEEL DRIVE....!!! Thats all im saying!! DO IT GM!

 

^^^^ it will never ever happen in Cobalt . The next gen G6/Malibu/Aura chassis(elipsonII) will be AWD capable though .....which one those they intent to make AWD is anyones guess .

 

Yeah ford doesnt really have anything to compete. They actually axed the entire SVT program and are moving over and lettering Saleen and Shelby pick up the slack. I definently think that the Cobalt should go AWD the handling would be godly and coming off the line it would RAPE.

 

I know out of the USA Ford has the ST wich I think is a turbo charged 2.5 engine

 

I actually heard it was twin turbo/twin charged.

 

That's not necessarily true, a lot of it depends on how efficient the transmission is. Also, RWD cars can benefit greatly just by slapping in an aluminum drive shaft.

As well, FWD vehicles also suffer some loss due to the trans-axle design, the extra play necessary to compensate for the steering causes loss as well.

A RWD rear mounted engine is another story. Driving these cars is like being strapped onto a rocket. :P

I'd love to see a reliable equivelent to the Pontiac Fiero produced today. That was it's only major downfall, the thing broke down every other week, but when it Ran, it was like an E ride at disneyland. hehe.

 

chevrolet has done a lot to keep the SS/SC under 20k. with the caliber going into the mid 20s, i think that it makes a lot more sense to keep the SS S/C as pure as they can. if a tubro is in the works, great, same with VVT... but lets think logicallly...


a turbo is cheaper than a normal blower... so this could make sense, it would probably also be a little be quieter... better yet. also, a turbo can be easier on gas as it's pretty simple to computer control the bypass valve these days and keep the boost at cruise speed right around ambient.

VVT and direct injection... these are a lot more money. will the turbo savings out weigh the cost of them? i have NO idea. my guess would be that since the 2,4 is more common now than a year or two ago, you may have a decent shot, but... i dunno.

 

just so everyone knows the solstice turbo is a 2.0 liter engine

 

i tried out an ST Focus, it's just a reworked 2.0L with a five speed gearbox.
it's nothing to get excited about.
