Dyno chart and pics after exhaust

[JustMe]

Hey all

Well , I got my exhaust finally done

Here are some pics and numbers
120whp @ 5680 rpm
151hp from the engine
thats 31hp lost in transmission (notcool)

Sorry, the dyno here ( the only working one in Estonia ) doesn't show torque and it also doesn't do printouts, thats why the pic of the chart

Here is the dynochart.

Now that jump @ 5500 rpm should be the point where the intake manifold goes from short to long or am I wrong?

Is there a way to get it open earlier? @ 4500 or something like that? How does it gets its impulss, from the ECU or does it monitor the rpm-s by itself and then opens?

Anyway, im glad with my results Next job is the port and polish in April

The exhaust system is 2 1/4"
It has a new catco cat , one straight trough resonator in the middle and the same on at the end. Header is 4-1.

Now about that jump @ 5500, seems like the US version opens the intake other runners @4200 . So what is my car doing at 5500?

that's when the VICS kicks in. the aussie version kicks in at 5500rpm too. VICS doesnt open new runners, it just gives the runners move volume which is the same effect of having shorter runners. you cant change the opening rpm easily because it's built in to the ecu
