Hi guys
As some of you may already know, keeping the heat out of the inlet of a force fed motor will help with not only power and economy but also help lower inlet temps and less chance of motor damage.

Purefuel (mark) from here has made up some inlet manifold thermo insulating gaskets.
I've been using one on my ep71 now for a long time and its held up perfect.
Also have had some other members test them and give some feedback.
What I found was my inlet manifold itself was a lot cooler.
So cool in fact that it took a while to heat up even in traffic.
The manifold stays a whole heap cooler than stock setup and never gets hotter than you can keep your hand on.

There made of 3.5mm heat proof sheet and are individually milled out and finished by hand. These are not laser or water cut.

The use of these materials are not a new invention and are common in two stroke motors and performance carburettor fed cars where heat can cause fuel to evaporate before it enters the cylinder and cause the mixtures to lean out.

Why would you need it? Prob the same reason u run an intercooler.

Fitment is easy and fit on without modification to the length of factory bolts and studs.
Here's some pix:

The real question is, would you tell your friends you were beaten by a starlet?

Hey Paul, pics aren't working for me mate.

 

Also, is there any chance of getting some real before/after temp figures?

For example, attach temp probe to inlet manifold or in inlet tract. Run car from cold and idle for 5 mins then rev at 2000rpm for further 5 mins.

Fit gasket, allow full cool down and repeat.

 

I know, probably asking too much for the sake of $60 but it would be nice to know. I military grade/ISO 9001/ NATA testing day in, day out so am used to having solid figures and full tracibility for comparisons.

 

Cheers,

Stu

If this spacer is already fitted, would the temp of the metal either side of it give enough indication of effectiveness?

This stuff is interesting to me

I like your thinking graham!
The head is scalding and the inlet you can easily keep your hand on.
It's 10x better than without.
If you had a choice, would you not want it to be cooler at all?

Yep, pics working now.  Looks good.

 

Paul, how long does it take you to fit one to a standard engine without a top mount IC?

 

I'll just multiply whatever you say by 3 or 4 to give me an idea how long I can do it in :)

Haha not too long.
The worst of it is the support bracket under the manifold that runs to the bottom of the block.
Prob half hr ing gluing and so on.
