to wrap or not to wrap?
Turbo Mini Forums

puttin a 45dcoe on my n/a in nxt couple off weeks, would it be beneficial to wrap the inlet in that heat wrap or leave it?

Wrapping exhaust manifold is top priority. Stop the heat at the source.

Here's mine, and my friend's:

it looks like your friends zipties may melt,

actually thats bollocks, its an intake....:$

cheers chaps, shall get on an get some then!

not sure about this one as it could HOLD heat in!

No, it would keep heat out The one with the zip ties is mine infact. Used along with this:

so have you tested it then?? how you know it won't hold the heat in?????

i think the temperature gradient is going the other way mat,

the best option is to ceramic coat the manifold on the outside and the mating flanges, copper coating first then ceramic. On a warm day I would get condensation on the outside of the inlet manifold. I personally don't think wrapping the manifold in a little blanket before tucking it up in bed will help !!

If Carling made Mini engines
it would probably be like this one!

Mat, because there's no heat element inside the carb. The carb is fed with cold air, colder than engine compartment temps. What's heating the air inside the carb? Nothing.

Put reflective coating on the inlet(chrome plate?) to reflect heat.

'Where does the engine go?'

Well the carb is connected to the headand that get hot, as well as the carb getting hot to, If the air cools it so much why is it that most carbs are still red hot after a hard run?

forced induction is a different kettle of fish mat, is this what your referring to?

most/all na carbs run cold

hence why some road cars need to heat the inlet to stop them icing up in colder weather

No I was talking about the NA I had. Yes your right in the winter they can Ice up, but in the summer, mine way always very hot.

The inlet is never hot when you're driving. It's when you're stationary that heat rises. The inlet is fed cold air ALL the time when driving.

Also, there is no chance that the carb is red hot on a N/A engine. PERIOD!

unless the timing is way way out

Doesn't matter at all. The carb is still sucking cold air from the outside. The faster/harder you go, the colder the carb.

Also, remember (PV)/T. When the air enters the bell mouth, pressure goes down(vacuum in a NA engine), volume stays quite similar which means temperature will drop as well. This is why you can experience carb icing even if it's not below 0deg C.
