BTB zorst can fixings ?

[Delbert]

Well they look like they should undo with an Allen key , but they are round 

any ideas what tool I need 

would rather undo tonight if I can rather than wait until tomorrow 

[Mark w]

i dont think they undo , are there any fixings around the main pipe entry into the can ? if so undo those and it will separate .

[Jonathan Kay]

Do you mean that you can see the remnant of the hex socket, but can't get a key to grip? So you're confident that they unscrew?

Well I cannot see another way in 

does not mean there isn't though

I had a tax disc holder with similar looking fasteners. They used a torx type fitting - quite small - just in the centre of the round bit. Not sure what size but if you have a big Halfords type socket set there may be a few to try.

and the winner is a 4mm torx 

excellent - thanks for the pointer - always wondered why they were in my tool box !!

 

[Delbert]

so whilst the fill was hardly burnt it was absolutely saturated and weighing very heavy , no wonder it was noisy the full was doing nothing except cooling the fumes ? Or is it supposed to be wet ? 

Anyway at least when re packed I will know what is in there

I used to run one of my CiC silencers with a CAT in side. Over all 850mm long but the cat was 300mm.

Built a new one out of parts left over without the CAT as no longer needed in Mod Prod.

Same length and 184mm diameter.   First run so not burnt off the fibre yet to expand fully yet the difference was signifficant.

Old @ 7000rpm used to be 98 -101dB

Yesterday 7000rpm = 93dB   Very pleased.

For dome reason the Busa's do sound louder but don't trigger the meters as much - has to be a frequency thing.

[Delbert]

Not sure about yesterday's meter 

I was 94 db - normally I am 104 . Hence the repack for Goodwood

​ tbh now more worried as fill was in tact and hardly charred 

really hope that the wet nature of the fill was why I made so much noise 

[Alan Bowler]

Really not sure about Loton meters. New Powerspeed on 1.8K. 5000 rpm.
On Saturday I was 101 dB (early morning, f-cold). On Sunday I was 93 dB (mid-morning I think, not so cold)

What was it saturated with?

Jonathan

[Delbert]

Water , a few absolute drenching on track and the can had no seal

 

As for the Loton noise meter I actually wonder if he was holding it back to front my reading was so low
