Carburator Spacer
just a little info
Wood Carburetor Spacers
Wood has a thermal conductivity rating of 1.02, making it the best insulator in the group. Wood carb spacers are also cheaper and easier to shape.
But there are disadvantages.
Its pores are what make it such a good insulator. But they also make it extremely absorbent. This means that gasoline and any other chemical can easily soak in and warp the spacer. The results are vacuum leaks and a faster depreciation.
And because of this, you’ll have to inspect and replace your wood carb spacer often.
Phenolic Resin
This material is the second best insulator of the four, with a thermal conductivity rating of 2.01. It’s also more durable compared to wood. It’s not as porous, making it more resistant to chemicals.
So if your spacer’s insulation properties are important to you, but at the same time you don’t want to deal with any additional maintenance – a phenolic resin carb spacer might be perfect for you.
Polymer
Polymer, also known as plastic, has a thermal conductivity rating of 3.90.
But while the rating is bad news for insulation, it’s good news for the price – polymer spacers are cheaper than phenolic resin spacers.
And truthfully, some polymers insulate almost as well as phenolic resin.
Aluminum
Aluminum is not good at insulating.
At all.
Its thermal conductivity rating is 1,665.1.
So what are its advantages?
Aluminum is super durable. Aluminum will tune your intake charge. Aluminum carb spacers are the only ones allowed by the majority of racing sanctioning bodies.
