I read somewhere the other day that with the Coablt SS you can't hear the blower's whine as much as in an Ion Redline (maybe because all the sound deadening material Gm used for the Cobalt). For those that have driven an SS or heard the engine...can you hear the blower? I've seen a few Ion Redline videos and you can really hear the blower screamin...I hope the SS sounds the same. Anyone know anything about this?

 

Pushing over to the 2.0L tech discussion.

 

In the future you won't be hearing any supercharger whine at all. The 2.0l ecotec is going to be tubrocharged.

^Based on some inside news and the Sky Redline info.

 

really all turbo now. Many they just love changing it up. I hope they aren't moving to turbo based on some bad experiences with the supercharged eco's

 

I doubt it's bad s/c experiences. GM has been using the same supercharged set up all all it's cars for quite some time, it's a reliable system but moving to turbos is where the market is. WRX, Evo, SRT4...all turbo.

GM is just finally get back to reality and making the switch. Not to say the s/c cobalt isn't a great engine, just a lot of people want the turbo experience from their 4 cyl, and the turbo will make about 10 more hp.

 

well the turbo 2.0 in the Kappa twins is 253Hp...

 

the blow off valve is only tight for the first year then u get annoyed

supercharger whine is way more aggresive!!!!!

 

Supercharger = torque+HP
Turbo = higher HP no real additional torque

GIVE ME THE SC EVERYTIME

 

i really doubt they will put the turbo 2.0 LSJ in the cobalt. If that was going to be the case they would have not developed the roots blower for it, they would have just taken the turbo 2.0 out of the SAAB 9-3.
the turbo 2.0 is for the sky Redline, but this hasn't been confirmed tot the best of my knowledge.

 

Yeah u can hear the s/c whine in the SS

But not a whole lot.

its not a screamer.

I'd imagine if u took the hood liner out it might be able to be heard a lil more.


But u can really only hear it when ur really GETTIN it, yah know

 

thanks for that info....Ski if it's not too much trouble do you think you could post a vid so we can hear the engine and exhaust? if not no problem...thanks again for the info

 

thats why im getting the rksport ram air hood

its functional so i should be able to hear the whine better

 

I dont know much about superchargers but couldnt there be something you could buy to make it whine louder? lol
Like you can get a better blow-off valve for ur turbo.

 

i believe ths rksport ram air hood was designed for the non ss s/c, the airbox placement is different on base 2.2 and the supercharged. i dont think theyve had the oportunity to work on the supercharged version yet. and as far as gm going turbo they would have done it in the first place, if n e thing they'll make it as an option like for 300hp or 350hp

 

The Sky RL/Sol GT will get the turbo 2.0, It could be that they want the roadsters to have more of a turbo feel/higher end feel, where in they want the Cobalt to have that muscle car like grunt off the line.

Turbos do give more torque also, just not as much as they do HP.

 

sorry but there are cars out ther that are producing more tq then hp numbers or equal numbers or close enough. wrx produces 227hp and like 215 tq, srt 4 250 tq like at 2 grand and 230hp, wrx sti 300 tq 300 hp, evo 276hp 280tq? see they all produce around the same numbers, hp and tq. gm was mostly worried about turbo lag with the cobalt.

 

Im not saying they wont make more toque, but usually compared to superchargers they give more HP but less TQ.

 

if you do the following things it will get louder. intake will make it louder and a pulley will make it louder, both is even better! just like the gtp/lightnings/03/04 cobras

 

ugh, guys.. gm wouldn't throw a turbo on the LSJ and have it lag until like 3,500 rpm.. give me a break.. a properly sized turbo on ANY engine will have 0, yes you read that right, 0 lag.. as far as the comment about "developing" the blower, they didn't have to develop anything.. the M62 has been used on gm cars before, it was on the series 1 3800 in the bonneville.. the only thing gm had to do was design the intake manifold, which they would have had to do for the lsj anyway, they just would have designed it to work with the m62.. the reason gm probably chose to use the m62 vs turbo is that they have a contract with eaton already for the m90 on the gtp's.. it'll take them a few years to do product testing on whatever turbo system they're going to use on the lsj (don't know if this'll count where they use a 2.0L turbo in the SAAB's) for longevity and failure rate of engine internals (again, if the lsj is different from the 2.0L ecotec the SAAB uses).

 

Another reason it'll take a few years, it to secure contracts with a turbo company for turbo's and necessary parts, along with stock piles for production and replacements for warrenty claims.

 

Except on the Mazdaspeed Miata.. Its programmed in to not make boost till 3500 to keep amateur drivers from ending up in a ditch. True story.

 

you are retarded, find me a car that has a turbo that boosts 100% of the time
and superchargers are more dependent that turbo setups bc they run off the engine, turbo's are tuned to boost based on other factors
get your facts straight

 

Ok no name calling and stay on topic.

This is about the supercharger whine. It has nothing to do with turbos. If you want to discuss it in a civil way start another thread.



I can't really hear the supercharger whine. All I hear is a little exhaust noise when you hop on the throttle. Of course I have the radio on most of the time since it's such a damn good unit.

 

same here i do here little whine,mostly exhaust noise so far the car is great, real eye catcher some guys here in toronto,canada in there civics and rsx gave a two thumbs up i think i must be the only guy in toronto area with a ss/sc

 

Doesn't that feeling kick ass? Strangely enough, not a lot of people know anything about the Cobalt SS here. If I even remotely say anything about it I get a "Huh?" and "What the hell is that?"


Zinner/Sleeper: Are you going to go with the Ram Air Hood / CAI? Do you think this will increase that SuperCharger's volume, along with adding it's beneficiary stats to the HP? I'd love for more people to hear it and wonder "Holy ****, what's that guy running?", they already
have no freaking clue what it is.
