i work for skoda and on a recant trip to the traning center in milton keynes i was looking over a twincharged engine on a stand and there is a hefty peace of sound deadening over the top of the supercharger and it is dead easy to take off with it being a eaton supercharger it might make a realy good noise just thort someone might want to give it a try

Easy to get access to without moving front bumper etc?? sorry for nooby question

it behind the engine below the inlet manifold ill put pics up

tryed to put pics on off my computer but dont no how help?

I want to know if this makes a differance to the noise as I miss not being able to hear the charger whine like I could with my old cooper-s

guys , does this make a big difference to the super charger noise and would there be any detrimental effect removing this

I've found a lot of this material is not only there to absorb sound but heat as well. I wouldn't like to lose anything that absorbs heat bearing in mind how hot the engine gets :no:

There is a guide somewhere on removing this insulation. It isn't backward replaceable as you have to effectively cut it off. Apparently it did make ur supercharger whine louder I don't remember any heat differences being discussed

The diagram literally translates it to 'sound damper/absporbtion', no mention of heat on the official diagram.

I think I have read reports somewhere on reduced intake temperatures after removing this, not sure how true that is though.

Just had a look and a quick fiddle and is possible to remove this from above very tight but you can get to the clips after a few grazes in the arms . Just awkward I bet to totally remove the cover??

Ignore that I think I was looking at 4&6 on the above diagram and I thing the foam on 2 and 9 should be removed .

Is that right

I removed the foam on my Ibiza and fitted the covers back on. The back cover protects the charger belt and tensioner.

I've taken it all of except 9 which needs the supercharger to be removed as the bolts go through it.

It does definitely whine louder but i have removed alot of other sound deadening aswell. Not sure if its enough reduction in temps to make a lot of difference but every little helps.

If it does double as heat insulation not a good idea to remove it if it’s under the inlet manifold. A extra hot charge is no good for performance.

Considering how hot the air gets being compressed I don't think it will make any difference, plus it's no where near the exhaust.

Also if the hot air can't escape the supercharger its self is bound to heat up thus increasing the air its charging temps.

Just tried this but can't seem to get any of the clips undone, managed to get the side pod off slightly but not all of the way.. plenty of skin lost off my arms :(

Any more tips to get the main supercharger cover off? I haven't got any decent jacks to get the car off the ground either. 

Food for thought. Although to be fair, I would just like to get mine back from the dealers sometime this year..... :(

 

But, in terms of mod's, making the wizz banger under the bonnet louder (Not bothered about improving the performance) does interest me.

 

Also thinking about a noisier wast gate and a Mill-tec too.... Proper old school....

I have the boring car to be sensible in...

The wastegate is built into the turbine housing - the wastegate actuator can be changed to a forge one. If you want dump noises the forge adapter is the way to go. These can be had for around 30quid if you look around. I have one going if interested.

Back on topic - does the insulation around the SC help with stopping quick changes in temperature? Or is it there purely for noise reduction purposes?

Cool - Fancy fitting it? many beer tokens of course  :cocktail:

Yours might already be done.

 

There must be a fair few Twinchargers out there where the Supercharger make a bit more noise

& the buyer will have no idea when going to look at a car at a Dealers.

Looking at the pictures; and I'm far from an expert, there does not appear to be any thermal rejection/reflection film/tin foil ect... If that housing was for thermal properties then I would expect to see some additional thermal elements to it. My guess is that it's for acoustic, and possibly minor thermal benefits only. Not forgetting of course the physical protection it would offer to the component by way of it's sheer bulk. FWIW

I always enjoy working on cars. I don't use mine as a do too many long journeys of which are at 2am so some piece and quiet is needed. The adapter did make grin when in the mood however.

Pm if your interested I do like a good road trip too
