ok thanks. I think I found another thread showing something is different and might be worth the purchase and removing the flap so it is constantly allowing more airflow?

Someone pointed out that under 4000rpm you would probably lose some torque down low if constantly open...
It was explained well but can't find it now

Depends what you are after I guess.

Why not just go for an over the radiator intake if you're after more power?
I'm having a think about what to do to mine. I quite like the sound it makes, but heard that OTR is even better.. need to hunt round for some vids.

I'm trying to keep factory look, but use all factory advantages.

ah right ok, so no good open all the time. wonder how to rig it up so it opens at 3,000rpm

Piece of string attached to it and every time you hit 3000rpm you pull the string hahahhaah

what is a bi-modal intake and where is it located and look like, compared to the bimodal exhausts?

From my understanding it does nothing for power it just brings induction noise into the cabin. BMW do it also but put their sound thru the speakers. Look where the tube goes. Straight into the firewall in front of the driver. In a SS Redline with bi modal when you select the bi modal setting on sport or loud or what ever it is, it also lets that valve open. Mine seems to get noisy after 2000 rpm.

You're referring to the mechanical sound enhancer (MSE). The bimodal intake fitted to certain HSV's actually opens to allow more airflow and possibly cooler air too, into the airbox via a valve / flap. They should have routed the aircon through it!

True

Only 20kw difference between holden rated 304kw vs hsv rated 340kw...
That means SS series 2 is actually about 325kw in hsv language...

Yes read / heard their kw readings were read different and that therefore holdens 304kw was closer to hsvs 340kw

Ls3 gets a reasonable sized stock cam from the factory,204/211 dur, 551/525 lift, 117 lsa as opposed to the 6.0 cam,196/208 dur, .476/.466 lift, 116lsa.
That would be why stock ls3 sound better with an exhaust.
Maybe why they run at least 3.27 gears with the ls3 motor,it would be a slug off the mark with the stock stall and 2.92 diff gears while running the slightly larger factory cam.
