Dynoed my GSR motor
I dynoed my motor yesterday with SRI/Header/Hi-Flow cat/Apex-N1.
My put down 166whp and 125lbs or torque.
From the last dyno in october there is a 2lb loss or torque which may have come from the install of the larger header and cat, but its not a huge loss so it really could have been something like the car not being cool enough.
I think the motor is pretty strong and should be well capible of laying down about 180+ when i get into throwing in some internals.
the air fuel ration was running a perfect consistant 13.2 threw all 3 pulls which is damn good.
Probally with the right Cam and piston combo and Chipped P28 and more fuel upgrades in the end I might even end up with 190 to a dreaming 200hp N/A tuned right.

Is that SAE corrected? It's been a while since I paid attention to GSR dyno numbers but that is about 14 whp higher than other GSR's Ive seen with bolt on's and no fuel management. Did you graph the 13.2 or just watch an Wideband display? Also why do you think 13.2 is perfect?

I was told by the guy that dynoed my car that 13.0 to 13.5 is supposed to be perfect. And the lines was straight and consistant that u couldnt tell that it was 3 diffierent pulls.

All depends on the car. Most of the N/A hondas I have tuned with a VAFC, Hondata or even POwer FC have preferred 13.6-13.7. I've even had a car like 13.9. An NA car isn't going to lean out and detonate before it begins to lose power so the numbers don't mean much as long as you listen to the car and watch the dyno graphs. I'd bet 13.2 is a little rich and 13.5-13.6 would make more power. That said depending on the wideband it could read too rich and you might actually be running leaner than is seems. Just curious the 13.2 reasoning.

Also, it is very rare that a Air/Fuel is perfectly linear even on a highly tuned car. A WELL tuned car will have a .3-.4 AFR fluctuation. Are you sure they are getting good readings?
Also was this on a dynojet or a dynapack?

dynoject. Well i guess i miss heard him or somthing but they him and everyone that was in the shop looked at it and agreed that the motor is running straight and and perfect which is all i need to know.
