K27 spooling noise question

So, got my car back on the road recently, after it spun a big-end. Whew, spendy.

Didn't avoid the "while you're there" trap, and rebuilt with GHL headers, K27/HF (and other goodies). Still running it in, and restricting both the amount of throttle and the revs for the time being. Apart from anything else, it's been pretty wet here recently...

One thing I've noticed - the stock paperweight would spool up and sound like an air-raid siren before getting into any serious boost, but the K27 with those headers gets into boost quite easily/soon with minimal throttle.

I've had the (factory) wastegate open more than once, but I have yet to hear the K27 at all - all I can think is that because I'm hardly using any throttle, it's not spinning fast enough yet.

I miss the sound - can anyone with a K27 comment if they hear it spooling at all?

'77 S with '78 930 power and a few other things.
