Its brake pad time again 

 

currently on the RS14 all round and i have got these to last 4 track days and some road miles which is a big improvement on the cl range i used to us,

im very happy with the performance of the RS14s 

my question is if i move to the RS42s what should i expect in relation to longevity and performance compared to the RS14s 

 

thanks in advance

As far as I remember when I researched them the RS14s were the more track discussed pad with a higher operating temp than the RS42s. So they'll probably be shitter

What about performance friction?

On the Exhaust front, Since my cat was removed mines been too loud so i got a 12 inch re packable silencer added in where the cat used to be and am still testing different packing materials but there is also this option -

For me, I have now also just bought a tubby mid section as I plan to cut the cat out of that and it may soon replace the new in line silencer as the Dutch have found they can take up to 330bhp and are far higher quality than the magnaflows etc. Sorting the exhaust is my main issue now.

 

Great to here of how your car has evolved.

Anyone got feed back on these

Won time attack on Mikes car. Good enough ?

I liked them when i drove dave's car.. Was quite impressed.

Hope that's just the cat's you're referring to. I've got a Magnaflow 3 chamber stainless silencer on it's way from the States at the moment.

Other SDCP's use the traditional layout with a perforated core-pipe and fibre-glass packing materials. Unfortunately, nothing survives inside a silencer placed just after the manifold - too much heat/too much gas-speed - and soon your SDCP is empty and not having much effect on your exhaust noise!

That's just not true. I've had the Tullet Decat Silencer since almost day one and the packing in it was untouched when I went to repack it. Literally untouched. The 1 layer of Acoustafil blanket in it was so unaffected by the heat the threads that bind it together before it expands hadn't even melted. Not saying the multi-chamber thing isn't a good idea anyway, though.

I think martin is referring to the caramic (magnaflow) cat that tullett put's in their 2.5" system by defauft, which is struggeling with our sometimes to rich setup systems, and failing, versus steel cat's that can handle the abuse more better.

Exhaust :
Well somthing a lot of us SC boys seem to be struggling with
Took mine of the car today, problem is the clam has to come of to get the huge back box of the car
So took it of
And looked in took a few pics of the perferated tube from inside


Which looked like the back box was empty

It's not repackable so decided to put a hatch in which could be removed and replaced whilst clam stays on the car

When I cut it open was very surprised that it was full of wadding like the day it went in

But it quickly became clear why it was still there




It was all being protected by wire wool which I'm guessing stops the noise being dampened but keeps everything inside intact

[CHILL Gone DUTCH]

Any way next I will remove the wire wool and repack it and get it back on the car Without the wire wool which will make it quieter but might not last as long

[CHILL Gone DUTCH]

One thing a did find was below the perferated bit here ( where I haven't cut open )



Is a resonator chamber and probably one of the reasons why other than Bedford I haven't had any issues with it

[Exmantaa]

Is that a 2bular muffler with the special resonator chamber?? (please make some detailed pics how that looks! )

Think Jim spend some time on that to make it as quiet as possible and for sure he knows how to pack a silencer... Wire wool as first layer is done often to keep the material inside. Seems to have doen the trick, but what about that portion without it?

Yes it is the 2bular with resonator built in There was very little perferated tube without the wire wool And the wadding was intact throughout After speaking to 2ublar they said the car would be considerably quieter with less wire wool and even better without it but will cause the material to fall quicker So it's time to see how much wire wool is required to keep as much wadding in as possible but trying to reduce the amount of wire wool so the sound is reduced

[Nev]

Chill, how are you gonna seal up that silencer box now ?

[CHILL Gone DUTCH]

It will be done buy putting a lip on the main section and riv nuts So I can still get access in the future Because of the amount of wadding there is in the it won't be a issue unless it all comes out again

3" Tullet system, four years, more than a dozen trackdays, no steel wool wrap and every sodding ounce of high temp Acoustafil was still there and the binding threads hadn't even melted on 75% of the silencer contents. So much stuffing in the end I actually had to remove some to fit the exhaust back together.

 

 

Likewise, with the decat silencer

 

 

Split it open again last year and still the same, although I repacked it with slightly less new Acoustafil and again, no wire wool.

 

I know everyone wants to blame heat but as long as you've got decent packing in the first place, it's clearly not the problem.

[smiley]

Would to rich setup dumping fuel in the system not help desintegrating stuff also?

(on my previous fill with ZT1, i only did 2 trackdays before it sounded empty again)

 

[techieboy]

Maybe, though I'd imagine lean mixture would cause more heat issues. Until this time last year I was on a Courtenay/Klassen Stage 3 map and I'd argue that was richer than it probably is now with OBDTuner.

 

Personally, I think it was way too densely packed to let the gas into it in the first place. There was 6 or 7 layers in the widest parts of the silencer. I've got a bag of Tullet's newest continuous fibre AcoutaFil to repack with at the moment (they said I shouldn't use stainless wool first) with a modified perforated tube that's partially crushed in two places to try and divert some of the gas into the wadding which is meant to help.

 

Failing that, I've got a 3 chamber silencer on it's way from the States to try.
