UPDATE: Pooners has given permission make this the official Group Buy list since we have enough interested. I have also added dates. This will run from April 15th - April 30th so that I can give the Aussie the numbers. That's two full weeks folks. Now for financials. I will collect all the money and send the guy one big payment. Then, I will provide updates to everybody on when they get here and ship them out the next day (assuming it's a viable ship date). And then bob's your uncle, you've a brand new manifold insulator. I now turn back to the original post.
-------------------------------------------------------
I have been in contact with a manufacturer in Australia that makes intake manifold insulators for the 3.6. Basically, they are a heat resistant 12mm spacer between the upper and lower intake manifold. This effectively prevents heat soak of the intake manifold thus getting colder air further into the engine before it gets heated up. This means colder air into the combustion chamber and thus, more power. This also increases the runner length.
Here is the dyno chart that compares a car with and without the spacer. Cool thing is the huge pickup in torque down low. Also, there was a pickup throughout the entire RPM band:
You can check out the site by going to http://www.maceengineering.com.au/_MaceProducts.htm then click on "Automotive Products" --> "Manifold Insulators" --> "Holden Alloytec VY-VZ V6"
Now for the good stuff. They are willing to do a group by for 5 or more folks. The spacers will be $83 a piece. Now, if you want them shipped directly to your place, it's $33 for shipping. However, he has offered to send them all to my place for $70 (the makes them only $14 a piece for shipping). I will then send them onto you guys. Shipping will be a lot less that way, so total price would be $97 + shipping from my Florence, KY. So really, just over $100 for a fairly significant, dyno proven pickup in torque and horsepower.
Like I said, I need 5. So who is in?
