Track day noise
Discussion
I'm thinking of trying my Cerbera on a trackday to explore it's performance in a safe environment, so I fancy a couple of local airfield days/
However these have 100db limits.
My Cerbera at Castle Coombe was measured at 104.6db with cats and a sports rear box at 4000 revs.
What do you think my chances are of getting below 100db with trackday silencers attached?
Would it be slightly quieter if I cheated on the revs, 3500 or below?

You not comming to the brands hatch novice day 30th May. Quite a few Cerbs there. Would be good to put a face to the name?
Nope - not quite yet - I'm not brave enough for a charge into paddock as my first.
An airfield has quite a large run off just in case it all goes wrong.
Tim @ ACT used to have a couple of sets of silencers he hired out for a few days. Give him a 
I bought a pair off him in the end (and have loaned them out a few times). Brought my decat/sports zorst down from 109 to 98dbs, and witnessed them take Tim's down from 118 or so to 104bds iirc. That was his sales pitch to me. When I saw that, I just said I'll have um

Tell you what; a Cerb with reasonably setup suspension will just fly through Paddock
no problems, just what the next right hander after the brow of Paddock hill, it don’t half happen quickly!

Dont be fazed by paddock. Its easy to keep it on the track through there. Just hard to do it quickly. Brands is quite a good first track as its so short.

Honestly I've been on a novice day before. They don't tolerate much angry driving. Its perfect to start you off. They relax the rules somewhat for experienced days and then you get some nutters being allowed to drive a bit close. But on a novice day you get the minibus showing the line, lots of instruction.
Yup - I'll work upto it though. This one is Abingdon which is just up the road. Brands is a two hour drive around the hell which is the M25
P.s. Anyway - got to save up for my Nitrons Obviously when I say save I mean, get past the financial controller at home 
MOT's in a couple of months - I might need them to get the car through that
