Stock Turbo PSI??????
 

Just trying to fiqure out what the bone stock PSI is on the Cobalt SS/TC Turbo. Please Help cant find.


Thanks in advance

Stock, mine boosted at 14-15 psi. Peaked at around 17 psi.

i usually see +1 or -1 of 15 psi

Thanks Everyone

ya thats how mine was to, and depending on the weather it can go under that and up to 20psi sometimes.

same here right around 15 psi.

is it true that stock cobalts in lets say FL boost at like 23 stock?
i dont know where i heard that but i remember someone telling me that.

never happened for me, I think I was getting 17psi stock.

Not true. First off the boost wont be the same all the time. On a hot day 15-17 is normal and on cold days, like sub 80*, I can see 13 psi. The car adjusts accordingly

ohh i gotcha.
sounds good.

yeah 17 in fl

16.5 PSI is what I consistently ran stock.

Yeah the ECU will adjust boost accordingly to achieve the power its rated at of 260. As stated, on a hot day it will boost more to achieve those numbers whereas on a cold day it will be less.

i boosted 9psi on a really cold day once.

normally mine hangs around 15 below 75, seems to creep up to 17.8 as you get to 92 or so and then goes back to 15 over 95ish, at 6000ft altitude i see 17.8 and i've seen 13.2 when it was in the 40's

I had about 12 psi or so but I am at mile high.

I swear I've gotten to 20psi before, but when I recorded it, it was 17-18psi.

Can someone please explain to me how I get 20-25 psi everytime??? I bought this used so maybe the previous owner put the GM stage 1 kit on?

ya u got some kinda tune on that, stage1 or something else.

^wut he said

as low as 13 in the winter and as high as 19 in the summer heat

so it boosts higher in the heat?

Im guessing when you punch it, the highest number the gauge goes to is what you guys are talking about, correct?
sorry, im new to turbos....lol

hot air is less dense so the pcm will tell the car to push more manifold pressure to be able to still achieve 260tq/hp

and yes the number on the boost gauge

The highest number it hits on the boost gauge would be what it spikes to then whatever it falls down to is the regular boost. Most likely will be around 15 psi on a stock tune.

what are you holding. 25psi spike and holding 20psi

when i go WOT, it goes around 9-15, then when it drops it goes to 14-20
