Forgive my lack of knowledge on this but exactly what does the thermal kit do. I have a Motordyne spacer on right now and love it but wonder what else this will do for me. I have seen the pictures on the web-site but am still confused. Please help clear the fog in my head.

i indeed had some problem removing the upper plenum (tilting was not enough.. to remove the lower plenum assy), and hence haven't installed
the thermal gasket that seats below the lower plenum.

With regards to the coolant valve to the TB, i haven't installed it yet too..
But would love to hear feedback on the two products:
1) Lower plenum thermal gasket
2) valve for coolant valve to the TB.

But overall, the products from Motordyne Engineering is so ingenius !

cheers,

Have a read of my earlier posts for my thoughts. I like the way my car is working. I would wait for the thermal heat sink so you don't have to deal with the valve. The valve is awkward to access and needs to be switched when the temperature changes at 55 degrees.
As far as the lower plenum access there are several hoses and two bracket assemblies and an electrical connector that need to be dealt with before you can complete that upgrade.

 

I get mine installed tomorrow morning at 10:00. I got the 1/2" spacer with the ISO thermal gasket.

Besides the directions provided in the Microsoft Word document provided by Tony, are there any other directions that I will need? Will the guys doing the install run into any issues?

Thanks,

Jeff

 

Hi Peter,

I will be updating the website once again to fit the Iso Thermal description on the first or second page of the site. But you can find a complete description in the installation manual. It should answer a lot of your questions.

Indeed, i was not so sure as to remove the Throttle Body or not,
since the Hex bolts there seem very very tight (and i only have normal allen keys..), so i was trying just to tilt the upper plenuem (with the TB connected) to the right hand side where the Z tube originally locates.
However, there are like two tubings connecting to the TB (at the bottom of the TB) that prevent from gaining enough clearance to remove the
lower pleneum without

1) removing the TB, or
2) disconnecting the two tubings which are very hard to access..

I would be very glad if i can have some help on this..
should i remove the TB? then take off the upper plenuem and proceed
on installing the lower plenuem thermal gasket...or
i should just leave it the way it is..

Btw, i am very happy with the 5/16" spacer that i have!
Tony is the man !

Cheers,
Godmans

 

Thanks for the props Godmans!

I now see why you were not able to tilt the plenum over. The hoses connected to the back of the plenum need to be disconnected. Its best to have someone hold the plenum up while you use a pliers to open the hose clamps. When the hoses are unplugged, its real easy to tilt the plenum over on its side.

What I have recently found is you can indeed unplug the throttle body harness if you have the battery ground wire disconnected from the battery. Also, be sure to not manually push on the throttle body butterfly valve.

With everything unplugged, you can take the entire upper plenum out and it becomes much easier to turn the throttle body allen screws. (but this is all optional. Do which ever is easiest for you.)

Peter...In simple terms the new iso-thermal kit keeps the air plenum cooler.
It lowers heat transfer from the engine intake manifold to the air plenum.

This gives you cooler air which = better performance.

 

Unfortunately, the coolant is circulated in the PLENUM rather than the TB, as in most domestics.

 

Thanks for your help Tony,
I would probably try insert the lower plenum gasket
either tomorrow night or over the weekend.
I would let you guys know !

Good luck, I didn't really have too much trouble with mine. I saw the two hoses and disconnected them evne though they weren't identified in the instructions. As well I removed a few bolts on a front and passenger side brakcket that were in the way. I didn't remove the TB. It's not necessary.

 

Thank you for the reply guys..
I would definitely wanna finish installing the lower plenum gasket.
The only think i would worry about is if i break something
in the way of removing the hoses to TB..

Anyways, i would definitely try it !!
I just can't stop visiting my lovely engine bay lol.

Btw, did u guys do per instructions given by Tony on the lower plenum
spacer? " Coat a thin layer of motor oil on the gasket to improve sealing"
I just bought a bottle of 5w30 for that purpose!

Hi Wayne!

Here's a sneaky peak at the Copper Iso Thermal.

It works by providing high thermal conductance on one side and high insulation on the other. Keeping the TB side heated and the plenum side cool.

I've tested it and it works really good.

Note: the copper tubing is bonded to the pure copper plate with silver solder for high thermal conductance. And the black rubber is 1/8" thick Nitrile. Heat doesn't pass through the Nitrile.

 

Here is a picture of the throttle body side of the Copper Iso Therm.

This side uses a stock metal gasket and just a very thin layer of the heat transfer compound (on both sides of the metal gasket) for increased thermal heat path area.

 

I believe it works kind of like a coolant bypass mod? but keeping
the coolant circulating the TB for better reliablity during cooler
temperature?
