so i went to test drive a ss/sc today just to see the diff compaired to the tc, and i have to say i was dissapointed in the sc, hp and torque seemed to kick in at to high rpm, and after being used to the tc, im so glade i didnt get the sc when i wanted to. i thought it would push me back in my seat more than it did, and i thought it would have more pull off the line, but i guess im used to my tc. not dissing sc for all u guys that have one, just like the tc far better.

 

of couse a stock tc is superior to a stock sc, what did you expect?

 

Instant power vs turbo lag. Pick one

 

 

I think the SS/TC spools very fast, i really dont notice much lag.

 

Driving both in a stock form:

SS/SC has a better throttle response (low end initial power)

SS/TC has a better top end

Which ever you choose, both have a benifit in a stock form.

 

word!

 

well my tc had way better low end power then the sc i test drove. i figured the sc would have better, but no it didnt. besides our torque kicks in at 2000rpm so we do have more bottom end and we do have pretty much instant power, as for the boost lag, the is almost non, why do people always us that against turbo cars? its not like we have 10 seconds of boost lag, maybe a second if that, ur not gonna get away from a turbo car in that short a time that easy.

 

I don't want to argue, but in all honesty I have owned both... Something may have been wrong with the SS/SC, but new VS new (both 100% stock), the SS/SC will have a better low end...

I will even state this, with my current car being a 2008 SS/TC, my old car was a SS/SC which was a 2006.


BTW you stated had, don't you own it anymore?

 

the thing about the ss/sc is that the powerband is so linear, that it doesn't feel like you're accelerating as fast as you really are. It's a very steady pull, because of the instant power from the sc. so it's not like it "kicks in" like a turbo does and throws you back. but stock, of course it's more than a half second slower with good drivers so it won't be as fast. it takes a good driver with a stage 2 at least to keep up with a tc. hp is similar, but the tc kills it on the torque. they definitely made a great improvement. the tc guys are going to blow the sc guys out of the water in terms of power and track times, no questions asked.

 

I would like to see a dyno chart of where/when an SC makes more 'low down power'

It is easier to get to the SC's low down power, where there is a slight delay with the TC

AND the way a roots blower works(makes more power as the engine is revved more, this is why the stage kits have higher rev limits) a similarly power SC and TC will drive COMPLETELY different because of the nature of the beast making more power as it revs on. Also SC has shorter gearing(because it has a 'narrower' powerband) so similarly powered SCs will have more top end than TCs

The words that we are looking for here is driveability(not saying the TC is hard to drive at all) and the SC has a MUCH more linear powerband than the TC

 

oops typo, has not had.

thats what i thought, i figured whoever had it before drove the crap out of it or something cause it did not seem like it was what it should be.

 

yep that was exactly my point. a linear powerband is great, but it doesn't feel as fast as a peaky turbo car will. not to say that the tc is crazy peaky, but u get the pictar.

 

i think the TC takes off pretty good from a stop. 1st obviously u have to take it a little easy so you dont spin the tires like mad but 2nd pulls pretty good.

 

you dont know much about turbos do you?
because a properly designed turbo will not have lag if tuned properly

and the only reason these cars are becoming "peaky" is because people are overboosting the **** out of a tiny turbo

find a stock ss/tc dyno and you will be amazed by the linear powerband

 

what would you consider over boosting? i was thinking of running 20psi when i HP Tune it.

 

Found one. Mine
Sorry to disagree with you on this one but I know my car and have driven the ss/sc many times. I FIND that the ss/sc gets the instant throttle response and the ss/tc takes a short time longer to get to full boost. I actually prefer turbo lag, there's just something about it I like



+1 I agree

 

Find someone that can drive with a stock SC to run against and you'll be unpleasantly surprised at how well a SC goes. The TC is hands down the better car as the motor has a lot more potential and the suspension and brakes makes it almost perfect. The TQ curve on MY car stock was perfectly flat all the way to redline and when it hits the rev limiter it's still pulling.

 

yeah. i feel disappointed with my sc afterdriving my dads tc but its tuned with full exhaust

 

The T/C has better mid and top I'd say not just top end. A bit of lag but the return from the Turbo more then makes up for it. There is no comparison really.

 

I used to have an audi a4 1.8t, and that had alot of turbo lag, BUT, the boost you get when the turbo spools up makes you feel like your rocketing, ive never rode in a supercharged car, but a few tuned NA cars, and when u hit the gas and EXPECT it to go, it dosent feel as impressive. Thats why the SC felt so much slower.

 

What turbo lag? Everyone talks about turbo lag, but I have yet to see it with my car. I hit the throttle and the car pulls and the boost gauge jumps...I dunno maybe Im just missing it. I thought the whole point of a twin scroll was to eliminate or at least "vitrually" eliminate any lag by 2 cylinders running one scroll and 2 cylinders running another to spin up the compressor much quicker.

Im still new to the whole turbo world, so I could be missing the lag, but I really dont think Ive seen any.

 

with a small turbo like on the cobalt there won't be much lag. it's when you start getting into the bigger turbos that it's more noticeable. But even a small or properly sized turbo will not produce the instant boost that a sc does. with a stock turbo like on the cobalt it's pretty much a moot point. but it's still not instant like a sc.

 

What do you consider instant. It takes a second for the air to speed up so even SC and NA cars have some lag or hesitation. Stock Turbo Cobalt does not have much lag at all.

 

did you read the post, or are you just trying to pick an argument. I said with the cobalt it's pretty much a moot point
