About to shield the intercooler box etc from the turbo and exhaust.Whats the best to use the Nimbus Lite or the Nimbus GII, both have similar thermal properties but expect that one is easier to bend etc than the other ?

Was looking at this today, also has anyone else bothered wrapping exhaust downpipes/manifolds or think its worth doing?

I have the GII, easy to cut with good scissors. will hold its form much better than the lite.
With it under the box and inside the IC box ( with a slight air gap) after a heavy run you can still touch the IC and not burn it.

Are you getting it direct? Dont buy it from Demon tweeks. twice the price.

To buy it direct it is a minimum order of 10 sheets so approx 1k.
Merlin Motorsports sell it in part sheet size but not big enough for my requirements so although a rip off Demon Thieves might be the only solution ?

i wrapped my exhaust complete. think its pretty good, you can actually hold the pipe for quite a few seconds when its hot so it must reduce engine compartment temps by a huge factor.

stinks a bit for the first few days though

The Nimbus is thermal sheeting which I will be using under the intercooler box and surrounding areas to reflect the heat away which radiates from the turbo and exhaust, in conjunction with exhaust wrap etc.

Looks like you can order just 1 sheet here?

DS, I ordered it direct, 2 sheets ( one for me one for PeterGUK) cut to size as well. smile
He is quite happy to deal direct if you do it via a company ( purchase order etc. )
If anyone else wants some I am happy to sort out the order for you. Anything to stop the DT rip off.

DS - What size of sheeting have you ordered? im offshore still so cant go measure the box...

I notice on the DEI part of the Nimbus site there are heat wrap kits with metal ties available.

cheers

I didn't notice on the site, does the sheeting have a sticky-back to it or how is it fixed?

I was thinking of just ordering the kit with two rolls of 2" tape, comes with tie's etc.

i used 2" wide wrap. cut it into strips and wet it in a bucket of water before putting on.

prepare to itch a bit and for it to stink for a couple of days after. tie wrap lenght is easy to work out, measure circumference of your pipe and add a bit for the thickness of the band.

When you say cut it into strips is that in relation to length or the 2" width ?
Did you wrap the boxes as well ? I have the Roush system btw.

For the exhaust wrap, you will need twice what you think,on 2.5inch exhaust you need 8 foot of 2" wide wrap per foot of exhaust ( allowing for overlap 50%), add in the cats.. I used about 60 feet IIRC

Tie wraps..stainless steel http://www.screwfix.com/prods/20645/Electrical/Cab... bargin at £10 for 50. smile

I would say don’t bother with the siliencers, If you have cats in, I would make sure these are very well wrapped.

As said soak in water first, as it makes it a bit easier to work and shrinks a bit when dry to help it stay neat and tight.

Another useful tip is to use a exhaust U clamp when you start as this is a lot easier then getting the first tie wrap on.

Also to note is when you cut of the ends of the tie wrap, they turn into mini razor blades, so worth spending the time and folding them over.

One last thing, if you ask nicely I believe PeterGUK has a special tool for getting the tie wraps very tight , as it is very hard using a pair of pliers.
