how may psi should i expect with a stage 2 kit qand a 2.9" pulley vs just satge 2 pulley.

 

maybe 15 or 16 for both

 

15 stage 2
16 2.9

 

all cars are different i have see Stage 2 a 17psi and 2.8 at 16.

i would even waste my money on stage 2. i saw one dyno and it was at 220

 

do run a custom set up then? if so what do u run?.

 

i have hit 15.5 with my 2.9 on stage 2 flash and stage 2 pulley i hit 14.5 but with 2.9 and cooling mods i hit 17-18 psi!!! cooling the heaton is you best friend!!!

 

I have all this but i havent installed it yet. Kid i no has the same set that i have but no headers he dyno at 253 at 16psi.
2.8 pully w/ Hub, 60lbs injectors w/ Casper wire harness, Dual pass plate w/ Cobra H/E, Option B kit, ZZP Headers, ZZP Downpipe, Megan Catback, NGK plugs, AEM CAI.

 

what cooling mods would u recomend? cobra h/c, meth ect.

 

Daul pass plate option b kit cobra H/E

 

is a daul pass plate hard to install? does it make a noticable difference by itself?.

 

its hard to install u have to take off the superchager and the manifold to install it but it brings down ur temps. u will see a difference.

 

thanks for the help dude.

 

im seeing 18psi+psi with 2.9,zzp downpipe

 

i like my meth injection set up!!!!

 

Stage 2 = 15.5psi
2.9 = 16.5 psi

Or around there, those are what you should see at sea level. At higher altitudes you might see a little different. If it's colder (winter time) you might see 1 or 2 psi more for both.
