I seem to recall that it is 3/4 of the speed at which maximum power occurs.
4250 is 3/4 of 5666 RPM

Buy a Rev limiter 
PS.. dont know the answer, but will find out on Tuesday! (SVA for me)
1. The point of a journey is not to arrive.
2. Never take life seriously. Nobody gets out alive anyway.

IIRC, you have to state on your SVA application form, the RPM at which max power occurs. It is this figure which then determines the noise test at 3/4
of the declared RPM.
Does that make sense?

My engine revs to about 6000 (1.4 k-series) and Peak power is 4500.
So they should test at 3375 max?

My tester ignored what i put on the form. Tested at 3,900 rpm but i was well within (approx 93dB).
Good luck - sorry this reply was too late to help you.

I put down 5500 on my form, guy let me sneakily change it down to 5000, it wouldnt have mattered in my case anyway, but i think if you've got a
good argument you can use a lower value, mine was that it simply doesnt rev that high

P.S 98db on one of those shiny cans i got last year.
