just got done installing my injen cai, and test driving. but now, im peaking at just over 15psi. im a little concerned considering all i did was put on an intake...

 

shut up and drive it haha enjoy!!!!!

 

15psi? stock otherwise?

thats too high.

 

i wont enjoy it if my engine blows



yeah. just over 15psi on an otherwise stock SS. just the injen at the moment.

 

do you have a leak somewhere? when i did my injen it definitely didn't do 15 psi lol

 

How cold was it outside? Cause I got 15 psi stock (or otherwise) when it was freezing out.

 

if i had a leak, wouldnt it be significantly less than normal? :S



it was about 27 degrees. still is... ugh

 

clogged cat?

 

Thats not right. I would say ^^^Clogged cat. How many miles? When I put on my intake I lost boost. But had more power. Also just an FYI, your maf sensor installed correctly? Arrow pointing towards motor?

Thanks,
Jas

 

everything was installed correctly. there is about 59200 miles on it. 05 SS s/c. oh trust me, there is more power. definitely noticeable. i dont know about the cat. everything was normal before...

 

the cat could be bad, you never know when it's going to go. you may want to pull your DP off and check it. if its melted/clogged, you can blow your motor if that boost starts to climb and you drive it hard.

 

maybe its how dense and cold your air is, are you at sea level? whats your elevation?

 

but it only magically goes above stock psi on this day? Not any previous cold day of the year.

 

he just added a CAI. allowing it to gain more airflow/cfm/psi, just a thought

 

i noticed no new amounts of boost with my injen intake, because they shouldn't be any. and Ive ran it from 80drgree weather to 10degree weather, your first look should be the cat, then the boost actuator, im not sure what the correct name of the part is, but mine was broke, i boosted 20+psi, it pinged the end of the gauge and still built power, till the motor blew because the dealership refused to fix it.

 

boost bypass valve

 

thanks xD im used to just calling it a wastegate or blow off valve. turbo >SC

 

this would not cause added boost. its shut when WOT anyway.... its purpose is to reduce parasitic drag at idle/cruising conditions. Not doing so (like mine) will lower MPG. Sounds like you had a clogged cat.... thought u might wanna know

 

Clogged cat within two hours? I dogged it before the install and I'd barely hold at the stock 12.5. Thantwo hours later it's clogged? Hmmm. How long have I got with it before something blows up. I'm grttng new headers and dp soon.

 

you guys jump to the biggest problems without looking for simple things first

I'm sure you've already answered this, but, how cold is it today?

 

last night it was 27 when i had it out. right now its 36.

also, on my way to work, i threw a CEL. my exhaust is extra poppy, too.

anyone? i dont want to blow my engine lol.

 

you won't be hitting 15psi stock just cause of dense cold air, the highest i saw on a great day for pounding the pedal was 13psi, that was in the teens of temps too. check your cat like said.

 

ill shal do just that.

update. nice orange CEL and significantly less gas milage.

 

I also have just an Injen cai, (installed 2 months ago) no cel or any issues. When at idle, or first starting the car, my boost gauge is pointing downwards at 20 psi. While driving or on the interstate, stays between 10-15 psi. That's just regular driving.

This is my only mod for now as well. with my boost levels, should I need to be concerned? Rather be safe than sorry.

 

10-15 in which direction....? below zero (hg?) or above zero...
