hey guys, a couple weeks ago, my brother (b18c1) and i (b18c sir-g) got our cars dynoed. heres the graphs...

my brothers graph

and my graph. i was wondering why my torque goes up and down so much compared to his which is relatively linear. i was told that i might need to replace my cap and rotor, and go back to stock 16 deg timing (i was at 14) and i already did both of those. would those two small things cause the torque to take craps where it does? thanks for the assistance

you already know what i think

 

lol, stalker
sorry i forgot to say, both our cars our stock, running the stock two stage manifold. only my brother has an injen SRI

So thats how much power gsr's make to the wheels? :nervous:. Wonder what mines gonna be...

 

nothing spectacular huh? b16's make even less. that's why i preach against them.

 

looks like something is restricting airflow/spark...ever do seafoam or replace your plugs? I bet cleaning out your carbon deposits and new NGK-V's would smooth that out a bit.

 

Thats what i was going to say. New plugs maybe. Does it sound like it is breaking up, knocking, pinging, etc

 

I had my car dynoed there. h:

The graphs look fine to me. The second one could benefit from changing the vtec engagment point.

 

yeah the graphs look fine to me.

torque spikes in the second graph could be due to timing issues like you said. what intake are you running?

 

now that i think about it, it looks funky because of the scaling used.
