Are you Paul Mugridge then? Did you race in the SoT on Sat?

[tetol]

yes thats right tp saturday in the sot certainly helped for sunday

Don't forget guys - decibels are a logarithmic scale, so a 1dB increase is a 50% increase in noise, so a 2dB increase is a double of the noise.

It takes quite a lot to go from 98dB to 105db!!

Ahhhh ... the penny drops.

You got some good starts on Saturday - I need to work on those!

3dB is a doubling of the sound pressure level

Oh picky me...

btw, for those that can't get there before the race I may have some scanned track notes, but without the last chicane before Camp

Yes, but here's a little gift to appease the mind

I've booked the last place on the 18th this morning

Emma (?) said that the info pack would be out in a day or so, so hopefully we'll know what the score is.

Oh, and I'm borrowing a friends road-legal CBR400, just in case eyebrows are raised at the DD bike

I've got my details somewhere, but they're still unclear from taking a race-bike perspective.

If I remember (and I'll check) they state that the bike must be MOT'able - a race bike wouldn't - so is this just to ensure that the noise levels are as per the standard can(s)? Or are they being very strict with this? I'm lucky enough to have a road bike that I can take, but would much rather take the Monnie as practice time is what I'm lacking at the mo' .

Mine also tested at 87db - Leo Vinchi cans like TP. Test was done at 6K rpm with the tester approx 3 feet and 45 degree to the end can.

I sneeked a peek at the guys clip board and all the ones I saw were in the 87 - 91 db range so I would be very surprised if any DD racer had problems with a 105db limit.
