HKS avc

[tridentt150v]

Ok, I've got a HKS series III avc fitted and it works fine etc.

I took the car to a dyno and got all the figures etc

My car was peaking out at 15.7 psi boost according to the figures.

So if I tweak my avc up to say 2.5 bar [35psi approx.], does that mean it won't make any difference cos I top out at 15.7 [1.1 bar].

I don't understand, currently my low/high settings are 0.75/1.2 kg2/cm [which is close enough to 0.75/1.2bar]. But I could reset the HKS to anything really, from mild to wild.

Somebody know the answer????

most likely peaking up near redline at 15.7 psi. I wouldn't go turning the boost up because it will boost very high lower in the rev range before the turbo runs out of flow.

Thats a negative, 15.7psi at 105kph on the dyno. Dropped to 13.9 at 170kph. But still doesn't answer my original question.

Thanks for the reply though BOOSTD.

Maybe someone out there knows the answer.

The turbo WILL boost more if you adjust the boost controller! When you refer to "low and high" settings, it is either one or the other. So if you have it set on high.....15.7 is pretty close to 1.2bar. The EVC should be reset every time you perform a mod. I have found my HKS EVC4 needed to re-learn after every mod or the boost levels changed.

I don't get it, does this mean that my turbo will boost past 15.7psi, I thought 15.7psi was the limit. I can vary the boost, it has a knob I can turn on the HKS avc. But I've decided on the two settings for the High and Low switch. I can change this with the knob and /or reset the internal settings using the Mod switch any time [but probably won't].

But a turbo must have a finite boost limit, and then you buy a bigger/better one to go higher etc [realise that this is also dependant on injector, pump, exhaust sizes etc too].

They just revved it out on the dyno and gave me the sheet and graph, but I am assuming that they would have found the boost limits and applied them. They just said this is the boost and we've set yours to 0.7/1.2 and that will be safe for this car and setup. Surely they didn't arrive at this figure by chance.

I think I'm getting more confused as I go.........

Your turbo WILL boost over 15.7 , probably 20-25psi. But ur engine and turbo won't last long. Any more boost with the standard intercooler and computer won't make any more power.
