INFO ON TURBO BLANKET [beanie]

[mudski]

So if you had two turbos hooked up on a bench and you fed them both with exactly the same volume and speed of air (say from a big compressor or something) but one was being fed hot air and the other cold air, the one being fed hot air would be pushing more out its output side?

I would say yes it would. As hot air expands, so in theory there would be more volume being pushed though because the air has expanded...

@ Roofy just went for a quick blast up to Melton 22ks and sitting on 100kph at 2000 rpm my EGTs were 300 c
so very happy with that, boost was 10 psi

Interesting topic.. Have thought of using one before but never bought one. Will do some more reading.

Be interested in what you come up with.

I've noticed lately all the later model Cat gear at work have beanies on the turbos and I don't think under hood temps would be a big deal as most are very well ventilated, so I've thought there must be something good about them. The manufacturer is working to increase efficiency and lower emissions on each new model. These turbos work really hard too. Can't remember the figures but I think they are around 30 to 50psi boost.

Just done a quick search on google.

The turbo blanket for a particular model of cat engine is over $10,000 so I don't think they would have them for no reason.

Also found this

Designed for the single turbo found on the Cat 3406E and C-15 1994-2004, this high quality turbo blanket is easy to install. The blanket is designed to protect other components underneath the hood by reducing under hood temperatures. The blanket also keeps the exhaust side of the turbo hot, thus providing increased throttle response as hotter air exits quicker and spools the turbo faster . The turbo blanket also keeps the intake side of the turbo cooler allowing for denser air to enter the engine which contains more oxygen and gives a more complete burn inside the cylinder.

I dont run the engine cover and the main thing I noticed before I fitted the beanie was how hot the IC got.
now you can touch it. This morning I wrapped the inlet pipe on the IC to hopefully get lwer IC temps as well.

I read that bit you linked and thats why I brought it to try and make what I have more efficient

so how is the turbo beanie holding up threedogs . i am thinking of getting one . does anyone know what size fits the commonrail motor turbo . and is there any issue with fitting around the variable vane actuator . when i put the 3" pipe on i could not get the heatsheild out . i am going to change the coolant soon , and if i remove the cabin heater flexible hoses i think i will have the room i need to get the heatsheild out . the beanie and some lagging around the top of the dump pipe would be easier to remove and work around .
