so some people on here said its not possible to hit 17lbs of boost with just a 2.9 pulley well here is the video

Cold air, elevation, clogged cat, faulty reading gauge/sensor, exhaust components all change PSI rating. Higher PSI is not always good as PSI is measurement of a RESTRICTION.

Example: my 80mm TVS pulley only makes 16psi thanks to ported head, header, and catless 3" exhaust. With stock exhaust mani and downpipe with 2.5" catback it made 21psi but was slower

 

well when im in high altitude(utah) its at 14lbs maybe 15 and isnt to fast but when im here at sea level(washington) i hit 17lbs and it hauls ass. but still some haters on here said its not possible and i just thought id make a video for them lol

 

I have a 2.85" pully and I made 17PSI of boost.
But now that I had to remove my K&N I barely
get 15.

 

on my 2.9" i get 16.3psi got full exhaust

 

X2! More boost doesnt always mean more power. I've got a 2.8" pulley and hit 15psi. I take it as a good thing

 

exactly. denser air=more boost.

 

by the way i have pulled on a few ss's with 2.8 pulleys lol havent had one beat me yet

 

It's in the tune

 

With a good set up someone with a 3.0" pulley could beat a 2.8... It's all in the tune and supporting mods

 

well then i can thank zzp for the awesome tune. =D

 

what he said ^

 

im deffinatly excited for the 2.7 and the 60lb injectors on the way haha

 

If you have stock exhaust you will see 16-17psi on a 2.9 at low elevation. I saw about 16.5 on stock exhaust and 2.9, now I see 15 on a 2.7

 

im on 2.8 60s 2.5 dp 3in cat back i see 16lbs of boost

pulls strong

1st video, with my vibrant muffler on

my cell phone picks up alot of the outside noise and other noises haha

 

ya same here i got the zzp stg 3 with a 2.9 pulley and K N cai and im pushing 16 boost

 

ya im making 20psi on a 2.8 tvs but its all about less restriction

 

bomb

 

I hit 15 psi on a 2.7. Before i put the header on i had a 2.8 and hit 17 psi.

 

boom... o wait were you making fun of my car ? hahaha you never know on here

 

haha nah 2.8 tvs = bomb like oh my that is sexy haha

i like the whineeeeee

 

yes, yes it does. with the raw intake it screams, sexy sound. but i want to drop pulleys again. gonna maybe man up and try the 2.5 but im afraid of my stock pistons. but i am running about 25 percent more efficient than stock balts... maybe more when i get my 3in dp

 

sweet, all sounds good to me

 

i dont have stock exhaust =D

 

just a video i took yesterday haha

no muffler
