ive used gareths and my knock link they sound exactly the same and i tell you one thing about using electronic rather than the hose on ear muffs is you turn em down

Fiecos Dan

Might have to grab a set of those. Thats the bad thing about home made - you can't adjust the volume, and soon gives you a headache.

GARETH T

there is a very cheap way how to make a set

buy one of these

http://search.ebay.co.uk/search/sear...=spy+listening

take it appart,,, desolder the mic,,,, add a tidy length of cable onto it,, and glue the mic to a croc clip

Rick

quite like the idea of 4 mic's/switchable.

Suppose could make that too!

Fiecos Dan

How good do you think they would be Gareth?

GARETH T

more than good enough,, i bought one just to try,, but totally forgot about it! if i get the chance,,, i might have a go next week

Fiecos Dan

the problem is on my Cossie, The dog box makes it hard work to hear det with my Det cans,

i've tried different mechanical setups, and positionings but still not happy.

GARETH T

you could always build a bandpass filter on your det cans

you can work a rough frequance of det,, but im fucked if i can rememebr the formula (somethink like f=2pi D)

Fiecos Dan

So safer and better option is the Sealey ones.

GARETH T

the sealey one wont be much better than the spy thingy,, they amp ALL sounds

a bandpass filter is very simple to make, and could fit inline with the mic or headphones and (should) get rid of alot of the background gearbox noise

Rick

As Simon says, pi r squared, although the ones my mum makes are round

GARETH T

its not pi r squared though,,,,,

Rick

what isn't?!!!

GARETH T

sorry mate,,, i didnt see you was joking,,,
woooosh,, straight over my head

GARETH T

900
-------------------------------- =Detonation resonant frequency
3.14 x cylinder radius

r called jay

where cylinder radius is measured in metres

eg For an 86mm bore, 900/0.043*3.14 = 6666 Hz

GARETH T

your right

Fiecos Dan

Ł125 is the best i can find, all inclusive.
for the sealey Kit.

http://cgi.ebay.co.uk/SEALEY-VS007-E...QQcmdZViewItem

GARETH T

go for it,, i think i paid 160 quid for mine which is the same kit

AlexF

Thats cheaper than I paid too

Fiecos Dan

Spoke to my usual part factors.


Retail is Ł145+, with my discount Ł122+, but he said he'll ring Sealey on Monday to see if theres any deals at the moment.

GARETH T

Fiecos Dan

i brought a set off ebay. (the link i put up earlier)

But over 3 weeks now, and

I still haven't recieved my sealey det cans.

The bloke is so useless. Never answers his phones.

i've asked for a refund if i dont get it by Tuesday.


Also found this. looks the same as the sealey, but Ł22 cheaper.

GARETH T

they look fine to me mate

Electronic det cans

Just my opinion but....

Someone I know (a tuner ) had a set and swore blind by them.
I was at a dyno session in the cell with the engine when I could hear det
and told him it was detting.
He said, no mate you are wrong, I cant hear anything on my det cans.

Some of these new det cans have high pass filters so you only hear
the high frequency noises.

It turns out, the batterys were flat and they were not working - obviously.
The unit had a led on which was lit too !!!!!

Luckily, it was low load and rpm so no melt downs.

Mechanical best IMO


We wont talk about the time I witnessed (with others) a well known tuner
map a 580+bhp engine without any kind of det monitoring.

Fiecos Dan

Simon,


with my Gearbox, Det is a real issue to disquinquiss (sp) on my and other mech det can's.

so thought i'll give these ago.

Fiecos Dan

Still no det cans,


and no repsonse from emails, nor phone messages.


How can i get a refund off this firm?

Should i give him Neg feed back? as dont want neg feed back on my account. (even tho i havent done anything wrong)

Fiecos Dan

As above still.

Tried emails, phone numbers, and thro ebay. But no response at all.


But now opened a dispute with seller thro Ebay.


And just gave him Neg Feedback, which i didn't want to do, but he's pushed me too far.

GARETH T

gutted for you mate,,, its horible that the wankers spoil it for everyone else
