I didnt see anyone really say what they are boosting at now?

With your Stage 2 and 3.066 pulley, what are you peak boosting at? What did you boost at before?

boostedss26

I have a 2.8 pulley and 42.5 lb injectors and i got about 17.5 but when i took the injectors out it went doen to 15. But i don't have the stage 2

ggarcia86

i know i've gotten to at least 16psi but probably have hit 17, i always am concentrating on the road or shifting to see me go all the way up to the rev limiter

Xenozx

Kool, thanks for the info.

2K5SS/SC?

15 psi is the highest I've seen. I'm usually concentrated on my RPM gauge instead!

Badmunky

I was runing about 12.5psi befor the kit and am geting about 16 psi after the kit.
The car pulls like a ****!

I saw around 12.8 stock now stage 2 (first day) seeing 16 flat. This was also only at 6000 rpm, im guessing she'll make a lil more.

2K5SS/SC?

I guess I'll get my buddy to look for me while I'm driving. I hate hitting the rev limiter, so I am always intnetly focused on the RPM gauge. It's also been in the 90's pretty much since I got the kit, which could be another factor.

hitting 80 kpa (12 psi) now around 105 kpa(15.5 psi) after stage 2 but haven't really been paying attention to it lately so it may be more

Stock, I saw 12.5. After the kit, I haven't watched it all the way to redline, but I have seen 16 psi when I get on it.

retrop

Up to 13ish with just injen now 16.5 with stage 2. Interceptor showed 16.9 for the manifold pressure, but it usually defaults to .4 when the engine is off, hence the 16.5.

sweet, I will be adding my #'s to this list soon

EuteR

damn.. i see 90 KPA stock in mine

No stage 2 yet though

maxpit

I have stage 2 with a 2.8in pulley and a CAI. I have peak boost 18.4psi.

Badmunky

Thats waht I want^^^ How much faster is it with the 2.8 over the GM pully?

2K5SS/SC?

ALright I took a look at it near redline, and it's barely over 16psi. I think after the clutch it's time to work my way down to the 2.8" pulley.

2.7 pulley gets me just a tick over 20 PSI

silverSS

damm, do you have the adjustable tensioner?

distillion

i get about 16 or 17 depending on conditions.

memphisr24

Using 2 different size tensioner pulleys, 2.75 and 3" tensioners.

distillion

ninja, you gotta take me for a boot in yer car oen of these days man

memphisr24

Ninja, by any chance, do you know what your a/f ratios are like at redline with the 2.7 pulley? Because I noticed the only tuning you have is stage 1.

I want to know this because I just ordered my Stage 1 and I have a 2.8 pulley sitting with me here right now . I want to know if it will be safe enough to put on.

BLKSS

90kpa before stage 2. Now im getting 115kpa. Note that WOT starts at 110 and climbs up to 115 after a few seconds.

GeoChevyCobalt

I am getting about 15 with stage 2. I got 12.5 before stage 2. I would also Like to try the 2.8 or even the 2.7. Did you have to have to file down the snout of the SC to get to 2.8 and 2.7?
