If your Already making 20 psi you might already have the gms1 or some kind of tune on it. Im pretty sure the ss/tc's only make about 15 psi stock.

If he's this impressed with the car stock I don't even want to be in the car with him after the GM Upgrade, bolt-ons and then Trifecta. Somebodies going to get hurt when his nuts explode.

possibly, but also depends on altitude and such

Knightwolf

22 lbs is definately tuned in some way or another.. stock boost would vary between 15-18 max, although maybe 20 at high altitude.. like for example Colorado. NO way that thing's NOT tuned.

SS-Performance-RS

That isn't entirely true, my car is bone stock and I've seen 20 mostly after completely a NLS but still. Other than those instances 18 is easily attainable.

Trunk swap FTW .... I've done both .... with my SS/SC i traded wings and went HI to low and the bases on the hirise wing left a crease in the trunk lid that the low spoiler bases cant cover.

With my SS/TC I swapped trunks and it was so much easier ....it's the only way to go.


The OP's car might be tuned .... 22psi spikes and 20 psi regularly sound too good to be stock. I know the car will boost higher in some situations but I'm guessing its already tuned.

SS-Performance-RS

Hmmm will keep this in mind but the proposed trade is coming off of a base balt. Well whats is altitude

I was getting 20 Lbs consistently and it was in HOT weather too. I saw it at 22Lbs the one time I looked. I don't look at the gauge very much...didn't really need to. Car is not tuned as far as I can *tell*. Wireing at sensors is stock and the engine bay is BONE stock, so I don't they did a Trifecta, since you would typically see some other mods (intake exhaust) with that mod..NADA..ZIP here.




They already did that on my drive back to So Cal!

I'm almost reluctant to do the GM mod now..I ordered the mod kit a week before I got the car thinking it could use a bit more *juice*...hehehe..
Ya right. I'll post results and impressions when I get it in soon.
BTW, my *running in 3rd gear test* (4k-6k RPM) was done with the AC ON! I just found out that if you have the only *Circulate inside air* switch ON, it also activates the AC as well. So that test result wasn't really as fast as it could have been (A/C robs around 5HP)....and the results I got were still very quick at 5.3 sec.

Most of us time our 'ricer pulls' from nailing it at 57-58 and clock 60-100 in third for comparison in HP Tuners

Under 5 sec tuned in 60* ambient temps 60-100. Many are faster than I.

SS-Performance-RS

Lol I still remember the ricer sentra i completely murdered the other day. His face=priceless.

HMM...that's pretty close to my test..it runs based on RPMs from 4000-6000 and that turns out to be *around* 62-94 MPH. So that's about 8MPH LESS in the overall range taken and another 6MPH *to go for me*. Boy..that would probably add another .5 sec to my time? I would like to see someone here with tunning mods run my test to compare apples and apples. Let me try and run 60-100 sometime and I'll post it here. I just ran another in HOT temps (85 ambient) and got 5.2 sec with the A/C OFF this time.

You are not stock.

jsscooby

Definitely doesn't sound stock to me either.

OK, read this:

http://www.zercustoms.com/news/Chevr...-SS-Turbo.html

It won't let me *copy* the sentence, but scroll down a little more than half way to " Turbo Charger and Air Cooler* section. It says "Maximum pressure is almost 20 Lbs".

Your car is tuned, 100 % positive.

Iam Broke

Yes it is, at 5000 ft above sea level. What is your elevation?

The ecu adjusts (when stock) to maintain 260 hp & 260 tq at the flywheel.

A tune can easily elevate the desired air load targets to raise the boost.

You don't have to believe us, go get your ecu calibration checked at a dealership and be prepared to lose the powertrain warranty if they don't match.

Better yet, find a local with HP Tuners, read entire the tune and we'll look at it.

You don't have to believe me, I've only been driving mine for 40 k miles.

Glad you like it BTW. Welcome.

I'm driving it at sea level in Los Angeles..20lbs on a regular basis. I'm going to get the GM Stage one installed next week. like I said, if this car was *tuned* you would think there would be other tell tale signs. Everything is stock under the hood and everywhere else.
BTW, another poster indicated that the tuners in gear test (3rd 60-100mph) were getting BELOW 5 sec and that was to 100MPH. I got 5.2 sec to 94MPH (6000RPM)..how much longer would it take me to reach 100MPH in that test (another 384RPM)? Probably 1 sec (because you're accelerating at around 6mph per sec in that range). So my test would probably come out at 6.2 sec tp 100MPH (I'll check the 60-100 soon). If they're doing under 5 sec (say 4.9) then that's 1.3 sec quicker than me. I would equate that to at least 50+ HP over me. Make sense?

I have a great idea, run it at the track and tell us what it clocks in at and what speed?

ronn

iTrader: (3)

That would be ideal, except I'm not a drag racer..zero experience. BTW, this *test* is fairly accurate for comparing like cars.

Didn't you say last page you did a 60-100 in 5.2 seconds? Or were you still talking the 62 to 94. Either way there are tons of guys on here that have a tune only. Why would the car have new tires with 8k miles? Maybe someone used them up real quick making 300/320. I'm glad you like the car tho, I was in the same situation when I bought my car, I thought it was seriously fast for being "stock". Then I checked into the gm stage kits and was very excited to think the car would be even faster with the kit, turns out just because everything looked stock didn't mean it was and my car was already gm stage 2.

20lbs is stock...another article

http://www.chevycobaltlink.net/forum...atures-gm.html

The turbocharger generates maximum boost of 20 psi. Because direct injection cools the intake process compared to port injection, it allows the 2.0L Turbo to safely operate at higher boost and higher compression (9.2:1) than a conventional turbo engine, increasing both output and efficiency

I was going to say the same thing about the tires ..... these cars are hard on tires when tuned .... even superchips tuned . Superchips tunes can keep the stock rev limiter.......... so having a stock redline (6300) really doesn't tell anything.

OP ..... go along at 40 mph in 2nd with traction and stability control off....... then mash it . Does it try and spin the tires ?

yes it's capable of 20 psi stock ...... but not at sea level . You can link your heart out .... we know . it will try to maintain 260hp no matter the elevation . People in denver might see 20 psi .... people in LA don't.

I tested from 62-94MPH. That entire range is then a full 8mph LESS than the tuners test. That's a lot. As I pointed out, to span that additional 8 MPH range (2MPH more under 62 and 6MPG more above 94) will take me at least another sec! That becomes 6.2 sec now..a full 1.3 MORE than 4.9. 1 sec is a minimum of 50 HP. My car is NOWHERE NEAR the level of the tuners!

Why would the GM data reference conditions well above sea level? Where did you get that tidbit from?

I have the instructions for GM install. The wiring has to be spliced into the harness at TWO loactions (also using 2 new MAPS). This car does NOT..I repeat ..NOT..have the GM install in it now. Sure, if they put back in stock MAPS and new stock harnesses, they *could* have run a stage1 PRIOR (to burn out tires?)..not likeley..and still doesn't matter since its' not in NOW.

This thread is full of "fale".

Glad ya like your car, get your car scanned and let us know if it is tuned or not.

stock boost level is 20 psi, howver mine will never boost above 15 lbs.

SUKXOST

After all this time I'd have thought more people would know. The stock LNF boost level is dependant on many factors. It consistantly changes to keep the hp/tq levels at 260. Warmer tems it will boost more to get the 260. Cooler temps and lower elevations it will command less boost. etc. Many other factors but there is NO SPECIFIC stock boost #. Please stop saying that "stock boost is...." "Stock boost today at todays temperature where I live today in my car.....is 19lbs right now.....today" is a better answer. LOL Hell, most will likely have varying boost levels just between the moring and the afteroon.
