well i just came back from the dyno and got some good numbers. 216whp at 192wtq on a mustang dyno. ill post my sheet soon. ill end up getting an intake and gmpp exhaust and maybe get someone to hp tune my car. hope i can get good numbers out of that.

 

i have the stage 2 + 2.79 pulley and i have a nice a/f ratio all the way to redline.

i just added a CAI and need to go back.

before CAI i dynoed at 256 hp and 238 trq.

 

u see i dont have anything to monitor my a/f for now. anyways heres my dyno sheet.

 

Pacesetter Mid-Tube Header, Injen CAI, Magnaflow Catback, ZZP High Flow Cat w/ Downpipe, GM Stage 1 & 2 w/ 2.8 PB Pulley, Ingalls torque Brace, DC sports Strut bar, JBP JBP CAB's, 18% tint, 6000K HID's, with 8500K fogs, Aeroforce Interceptor SS edition, Shorty attena, BKR7E plugs and

 

remember, not everyone is in the same conditions.

at 2200ft altitude, the stage 2 pully barely, and i mean BARELY at 7krpm, nudges 14psi.
with a 2.9, you might see 15. and with a 2.8, youll sneak 15.5 maybe.....

at sealevel? i wouldnt touch the 2.8 with a barge pole.
there are people at sealevel who are taxing their injectors more with the stock stage 2 pully, than someone at altitude can with a 2.8.

 

true enough.

you also can't rely on the stock gauge to give you an accurate reading. which is what most people are doing.

my gauge is reading 16 psi on the stage 2 pulley. but the ecm is reading. 1.08 bar.
which is no where near 16 psi.

 

the numbers im talkin about are from my ECM.

 

other people don't see this though.

anywho

 

IM at sea level, and see 18ish PSI.

 

​​​​​​I have 80 pd injectors long tube 3 inch all the way, with the 2.9, and I hit 17.4 pds boost, I'm on 17 inch rims
