This will be an alternative for people who don't want to take the turbo off to get the same effect.

It wont really be the same because your solution doesnt contain the heat in the housing, also you dont have to take the turbo off to install the blanket, it wraps around the housing. Unless there is something I dont get about 944 turbos from stopping this...

Landjet

If you have something seperating the underside of the intake from the heat of the turbo you will significantly reduce heat soak in the intake. You will also keep what heat rises from the engine from soaking into the bottom of the intake. This will obviously be a benefit in cooler intake temperatures. Yes there may be additional reductions in covering the turbo completely but we will see what reading we get with this and go from there.

Would be a good idea to cover the turbo in a blanket in your testing too. By far and away the most heat will be coming from the turbine housing.

Heat from the engine will be transferred to the intake by virtue of the fact they are connected! Not just because the heat from the block and head rises... Try this, make some nylon spacers that wont transfer nearly as much heat that metal does, and put those between the intake manifold and cylinder head. This will reduce the heat transferrd happy trials.

I told ya NZ was a big fan of ...ummm...probes...
He's been there and can probably save you quite a bit of research time...
just don't ask about the sheep.

I do like hearing the different idea's and views and I won't ask about heat transfer from sheep.
I realize that since the intake is connected you will have a certain amount of heat you can't get rid of but I hope I can help cool it down on the hottest area of the intake. If this project works well then next will be a turbine cover. I just like trying out new ideas and other ways of doing things. I have been in the aircraft industry for many years so I thought I would finally try and put some of the materials and ideas together and do some good. It may not be feasable but we'll see.

Seriously look into the nylon spacers between the intake and head Should be very easy to take a manifold down to the local profile cutter and get some made.

Landjet

Would the nylon spacer take the place of the gasket? If so would it seal ok in your opinion?

reno808

yes and yes. It would also be reusable. I seen then before and used them too. the best thing about it its one piece and you can make it your self.

my spacers are that phenolic plate like bakerlite I think just useing 5 gaskets would work pretty good I had the spacers and a stainless heat shild above the hotised and down pipe and my inlat manifold was always within 10 degrees C of ambient . oops maybe the bonnet vent helps too as it means the manifold doesn"t have to deal with all the hot air off the back of the rad and IC

TRP951

id be in for a phenolic spacer if you came up with one

Adam, in getting +10 on ambient where did you take you intake air from - outside the engine bay? I'm having problems now its summer here - over 40C intake temps sometimes...

Geneqco

Well, such an abundance of shhep in NZ and such cold weather... it all started innocently enough... with the camping trips... they'd grab a sheep to sleep with to keep warm. Things "developed" from there...

gt37vgt

mike well i just had a thermocouple in the post IC pipe but the manifold has always been cool to touch . you would have a temp probe in the planum to run the EMS ?? and I'll say again my beema had -20c inlet temps

I talked to a friend of mine today that has a couple of CNC machines in his garage. If I can get him the phenolic stock he can profile the intake and cut spacers for me in a few weeks. I will keep you updated.
