172 inlet manifold PTFE gasket

[hill_power_clio]

Has anyone ever used one, or know anyone who makes them?
Typical JDM mod which usually shows good results.
I know clio williams forum lot were looking at getting them machined for valvers but it never materialised.

[hill_power_clio]

nobody!?

[benji&eka]

ptfe gasket?

[Cookie]

Polytetrafluoroethene gasket?

You mean teflon? Never seen one for a Clio

[benji&eka]

y does it show good results?

[Fred@BTM]

helps to stop heatsoak up into the inlet, so cooler air

its been done for years

[benji&eka]

does it really! interesting.
seriously. i must live in a cave lol
embarrassing as i'm in the trade LOL

[hill_power_clio]

does anyone make 172 ones? I made one for somebody and was thinking about selling it as they don't want it anymore and was wondering how much to ask. Was just going to see if anyone else made them? Possibility of being able to get a batch made up in the future.

Sorry for the bump and maybe a re-post

35pounds

Who's going to try?

[Fred@BTM]

3mm thick, hum, you might encounter fitting problems there dempending on which rocker cover brether setup you have

Somebody buy it and i shall try it

[mattjk]

If you put that on you may find that the inlet wont mate with the plenum correctly. Benr said to me before that its not really possible on these engine as the gaskets are too thin to have any benefit and if you made it thicker it wont fit. Would be interesting to try although not worth 35 quid imo

[Fred@BTM]

if you have the later 182 rocker cover breather you'll be ok, but the earlier 172's and the mk2 172's will have problems

[murcod]

These would be a good idea IMHO along with ceramic coating of the inlet manifold- has anyone tried that yet?

Here in Australia I've witnessed some ridiculously high inlet temps of 82 degrees Celcius on a 42 degree ambient day. The lowest on that run was 65 degrees (logged via an RSTuner.)

Assuming because the way the oil seperator sticks up into the plenum? Didn't know it was different on the 182, hows it done on that?

[Fred@BTM]

its flat with a tiny hole drilled in the casing

[Burp]

on a 172 would you have to change the plenum and oil breather to get the 182 set up?

[Fred@BTM]

you might get away with it, but i reckon a bit of modification will be needed

we had a couple of sets made for the V6, was very effective..... inlets were colder and FAR less heatsoak from the engine at standstill....

trouble with the F4R is the gasket is alot thinner... a 3mm one wont fit at all well...

its a product we would like to roll out, does depend how many people would buy it..

the gasket would really have to be the same or very close to the thickness of the OE gasket

I have a mk1 172 and can see the benefits from this but I dont think its worth 35 pounds.

As a student of engineering I dont see the need for the gasket to be 3mm thick as PTFE would hardly conduct significant heat at much smaller thicknesses as long as no metal parts were touching.
