Had the Stage 2 installed today at Burien Chevy (Sleepyguys suggestion), they did excellent job. Mechanic that installed it was very impressed with how fast it is. On the way home I-5 was packed with cars and cops, so when I finally got past Stanwood I got on a back road and went thru the gears. Car is much quicker, I am very happy with it.
I was thinking my next mod would be a 2.9" pulley, everything else is stock, any suggestions?
Saw the "Cavi King" in the parking lot but never saw Sleepyguy. That is one nice ride.

 

Thanks bro.... Stg two gets a 2.88 pulley and thats what you have on there. I was busy working on a C 1500 front and rear brakes transmission stuff oil cooler lines P/S pump etc...... FUN ****

Fill out a good CSI report for us that would be good. Help us for helping you.

 

Stage 2 does NOT come with a 2.88 !!!!! Its like a 3.1...

 

Way to go Code.Getting ready to go out and install my 2.9
You're right Lewis,Andy justblew the math conversion from MM to IN
My Stage II is on the car of course But here is a stock vs 2.9 to see the difference

 

stg 2 comes with a 3" pulley.
stg 3 gets a 2.9" and the ecu crap

 

Ok,so what's a silly millimeter?...and the answer is......

Stock Pulley = Really Big
Stage II Pulley = 77.9mm x .03937 =3.066923 in.
Stage III Pulley = 76mm x .03937 = 2.99212 in.
Nates Pulley = 2.9 in. x 25.40 = 73.66mm
With my limited math skills that's as accurate as I can get

Oh yeah,and the ECU crap for the Stage III LOL!!!!

 

Any idea what to expect from 2.9" pulley? I am also considering Vibrant long tube header with their downpipe, when I get more $$$. I believe this will lean out the stage 2 tune.

 

Mike has a 2.9 on his car but he hasn't really said much about it.I won't know till I get it on but I'm hoping for a little less soot in the tail pipe

If It doesn't quit raining it may not get on there today

 

mike who?

i see... im very forgetful with names :-(.... however to my defense i dont think ive met thisperson.

 

I like standard!!! it is easier to make measurements............

 

Ya I have the 2.9" on mine, but I don't have much to comapre to because i never ran the stage 2 pulley from GM. I just went straight from the stock pulley to nate's 2.9". But the pulley looks great, and performance was killer going from the stock one to the new one.

 

I think you guys are measuring the full pulley diameter. 2.88 is measured from the groove in the pulley where the belt sits......not the full pulley size. Kinda catch my drift?

 

Pulley size is measured at the top of the ribs where the belt rides, not at the base of the grooves.

I wasnt refering to the base.
