..Out of curiosity, what kind of boost levels are you guys typically seeing on the stock boost gauge?

I'm seeing around 13.5-14 then finally going up to about 15 around 5,500. Is that the norm? Or are some of you getting more than 16psi? I saw 16psi the night of installation, but never saw it again.

I am running the boost bypass mod as well.

 

I am seeing 15psi and I don't have the boost mod done.

 

I see almost 15 all the time with the stock pulley

 

that doesnt make sence

 

R33P3R007, Does your boost gauge sit above 0 psi when you just turn the key on?

 

nope. but it also explains why my cat got toasted, and GM wouldn't fix it. because I see too much boost.

PS. I never used the boost bypass mod either.

 

reapers car sound good (he has no cat with stock exhaust)

 

Dude if you are seeing over stock boost without a pulley you have a clogged exhaust system creating more restriction creating more boost. That is a GM defect. I have a 3.15 pulley and I am seeing 14.5 lbs of boost so I would take it that a 3.1 should be 15 psi. For 16 you would need a 3

 

15.3 PSI with a 3" pulley. 22 PSI with a 2.6" pulley.

 

Geez I must be doing something wrong. I barely see 15psi @ almost redline. The majority of it is 13.5-14 psi.

 

22psi You are one crazy mo fo jmc007. Well someone has to try it. Do you have any new dyno's? That thing has to move......well when the tires finally grip.

 

Ill let the video explain it, its actually kind of hard to see, but you can see the 15 mark and it hits that right away and holds right up until the boost bypass kicks in

Well I have the SFPH 3 inch pulley and I am about 14.5 psi. And I only hit that just as I am at the redline.

I wouldn't get too worried your doing good at the track right

 

Yeah bitch your in the 13's akfbkjabgf!!!

haha just playin man, I wish i had the driver stage 3 mod

 

Unfortunately, i have some timing issues ! I must clamp the MAP sensor or scale it soon. Just stay tuned, I do my possible to let you informed, as long as I have enough money to throw in the car.

 

That's true, I guess i'm just a littled dissapointed, my car hardly ever made the stock 12.5psi, I suppose I had my hopes a bit high as far as the boost increase. But you're right, it's at the track where it counts!

Dude, your car seriously feels like it'll be mid 13's...I'm not even kidding.

 

haha, hopefully you can give my car the driver stage 3 mod when i finally get my car fixed.

 

Dude your car seriously feels like a mid 13 second car...I'm not even kidding lol.
