Gents,

I am looking for information from some of you on what is your HP before the mods (car virgin) and after the mods, what mods you done when you did the dyno.

I had my car dyno with mods I had the following results, and I wonder if the tuner missed something.

 

That seems about right for the modifications that you have. Will probably notice more when you get some more of the exhaust components.

Here is my graph from when I was stock and a quick tune thrown on after 2 runs of adjustment. Don't mind the torque numbers though.

 

I am planning to add a axle back Tanabe exhaust. I found a used one locally. I do not think a Y-pipe will add anymore based on what I read here, it is for a show.

 

Sorry no stock dyno but here's 2 different dyno a year apart on my g37x
Mods: hot air intake, hfc, axle back, upper plenum



Z1 long tube intake, ported tb, ported z1 plenum and Lower intake manifold, stillen ceramic headers, z1 hfc, top speed cbe

 

Why? That is your actual torque at the rear wheels when in 4th gear under full throttle. Most dynos divide this number by the tire radius, diff ratio and gear ratio to estimate it at the engine.

As for if it is good, sorry I don't know anything about the G35 mods.
