Weird question, has anybody ever measured the temp of their inlet manifold after a run or a race.

depends if the cars carb or injection, should be quite hot if a carb though near the base of the carb you can get some white ice if you've been gunning it.

why you asking?

Not done it yet but I do have an air temp sensor for my ECU so will be keeping an eye on this in future.

The intake on the v8 is in the valley the heat soak into the intake plenum was quite high. After a good blat you could hardly hold your hand on the top of the plenumn.

Interesting question ! My mates in the process of collecting bits for a turbo conversion for his type r civic one of the things he came across was a thick nylon type inlet gasket supposed to stop heat soak to the manifold!

Dave................

if your inlet manafold is getting too cold see if you can get some metal head - inlet gaskets as they will transfer the heat better. I have these on my buggy to stop (help) the carbs freezing up. I find after market carbs and K&N type filters usually get too cold rather than overheating.

ive gone back to investigating alternate materials for custom inlet manifolds and/or runners

ive got (or am very close to having) moulds for ali casting, and there is a local foundry im approaching but im looking for something more diy-ish
ie plastics or resins

any ideas.

I know how this sounds, its along the lines of:
im thinking of building my own gearbox/engine/cylinder head/socket set

Build a small kiln from fireproof stones which you'll find in hearth's

get a biggish bottle of Map gas or oxy-set and a buch of broken ally pistons at the scrappy's. adn cast them yourself.

lots of info on this on the web.

i was building a waste oil fired furnace acutally, and i have a lot of info and a little experience of casting

now im just weighing up whether its actually worth it or not
