how much boost does a stock ss/sc run? I'm running about 14-15 and i don't know if that's stock or not

 

typically its 10-12 psi. Its not stock because you have a smaller pulley as staged in your sig.

 

well, after I made my signiture I got to looking at the pulley and it's pressed on...not bolted on as if it were aftermarket.

 

if its pressed on its the original one, but stage one is different injectors and tune.

 

what does that make your boost go up to?

 

If you have a stock pulley you probably have a clogged cat

 

Stock boost is gonna be 12psi like said above a couple post ago

I think you need to state what size pulley it is, stage one could mean many diff things to us all, we all think differently

 

if it looks like this, your stock

 

This is true. OTTPs stage 1 is actually GM's stage 2

 

I'm pretty ignorant of this stuff so i don't really know much about any of it. do you know what size pulley it should be if it's stock?

it looks just like that.. why would my boost be 14 or 15 then?

 

Traaviper did you get you're OTTP stage 2 on order yet? I think stock is 3.1"? If it looks like the pic then you probably have a clogged cat. Restrtiction will make you're boost go up

 

with cai, dp, catback i had 14lbs

 

I don't know what kind it is but I know it's got a full system on it and part of it is magnaflow. idk what kind of headers it is either...i just know they aint stock headers.

 

Yeah if it looks like that then your deff. stock

it doesnt matter if your on the stock pulley, you have supporting mods like catback, intake, etc.

so its very possible to overboost, yes supercharged cars can do it too

I would just buy the staged kit from whoever you want, get it tuned and have fun with it man I loved mine before I got rid of it

 

Oh if the header is not stock then i guess you're just free flowin haha

 

typically with exhaust boost will lower.

 

my boost gauge just went out so I have a new one ordered. so other than the new boost gauge, exhaust, intake, and intercooler (i think the intercooler is aftermarket), it's all stock.

 

Fixed

 

Thats what i thought too. But i'm not gonna argue

 

haha. thanks

 

Oh my buddy with his ZZP Shorty Header, Catless dp and custom 2.5 catback spiked 15 all the time on the stock pulley

But all cars run differently.

I dont have the LSJ anymore my mind has totally changed lol

 

I don't know what all this car has done to it. so, im afraid to get other **** done to it and get something that's worse than what it had before. lol

 

yah..

just making sure you knew what it was actually called.

I dont think I have ever seen a boost spike on my car. Weird.

Also 15 on stock is very weird.

I'd say since his boost gauge went out that was the culprit. That is just a guess.

 

Well you would think with more flow the supercharger doesnt have to work as hard which would mean less boost. I'm running 15psi right now with my stage 2 and am curious how it's going to react when i bolt exhaust onto it.

 

like I said before, I'm pretty ignorant of all of this stuff but from what the mechanics said that I've talked to, an exhaust system is supposed to open it all up more. idk if that would make the boost go up or not but the supercharger run on a belt from the engine so if the engine was able to run faster from the exhaust opening it up, you would think that the supercharger would be able to turn faster and create more boost. but, idk.
