Rwhp with 2.5 pulley ?

[864svt]

Just curious what everyone is making with the stock m122 blower and 2.5 pulley?

I'm hoping to have a few pieces installed and tuned in the next couple weeks
Wondering what it should make.

2.5 vmp pulley/idler
JLT resonator delete with Aimsoil dry filter (no power from that)
Corsa sport axle backs
Sct tuned

Just ordered vmp triple pass heat exchanger with fans, 3x capacity reservoir tank and 170 degree thermostat

I would think you would see 535-550

I am making about about 625 hp and torque with a 2.6 pulley but with mods. See sig. You should make in the 550 hp range!

Thanks for the reply guys, was hoping for anything over 525 so I shouldn't be disappointed

 

[CodyK7]

Yup you should put that down easy.

How much boost are you guys seeing with only the 2.50 pulley?

OP, you are going love the new power and whine from the M122, very noticeable Not trying to jack the thread but I just installed a JLT 127mm CAI, 2.5 pulley, 90mm Idler, 1 step colder plugs, CJ 65mm throttle body with a VMP Tune yesterday. Havent dyno'd her yet but any thoughts on what I should see from more seasoned forum members? Seat of the pants dyno says much more because now 2d gear is like first was and Im glad I got some MPSS's because the Goodyears are like ice skating right now.

I just did a 2.5, 90mm, 127 JLT, roush mufflers, and colder plugs. Made 564hp and 550tq. This was on a 2011 with 8200 miles. Made 13.85lbs of boost. Car pulls much harder. Now I just need tires and lower control arms.

Custom tuned, 530-545.

SCT tune.... Probably 10-15 less.
