Just installed the Motordyne Copper Iso-Thermal upgrade.

Here's a few pics.
I'll write up a few impressions after I've put a few miles on.

On the initial test run, I couldn't believe how much cooler the plenum was to the touch.

 

I'll post up some initial impressions later this week.

On Friday we'll be headed out on a 2000 mile roard trip from Toronto to the East coast;
Then down to Boston and back home through Vermont.
We should be above & below the 55° threshold many times,
so it should be a good real world test for the copper thermal isolator.

 

I second that.... been testing the product for nearly 2 months, and I can actually put my hands on top of the upper plenum without getting burnt.. (I got the coolant valve controller though)... and the throttle body is sooo cool even after an hour of hard run...

cheers,

FWIW, here's a few install tips for those that buy the Copper IT kit (CIT).
------------------------------------

1. Loosen the TB bolts b4 taking off the upper plenum, they are very tight.

2. make sure you have a set of GOOD quality metric allen wrenches

3. DO NOT unplug the TB from the harness or it will have to be reprogrammed!

4. After the upper plenum is removed install the CIT next, to seal the coolant lines.

5. When installing the CIT slide the hose clamps off the hose & onto the copper tube.
Then connect the hose & slide the clamp back down.
The ferrule on the tube is larger than OEM & it's difficult to slide the clamp over.

6. Be discrete with the amount of heat sink grease applied.
If you use too much it will squeeze into the TB when you tighten up the bolts.

 

so to install the Iso Thermal you have to take off both upper and lower plenums?


so its like re-installing the plenum spacer (if you have one?)

 

Yes the new kit uses different post spacers (six in the middle) as well.

The new ones are much better, they're one piece & look like nylon.
No more retainer/spacer/silicon stickies
