Before I do something stupid...

[1969zeitler]

I am removing the heat pipe from my 40hp intake and I am using a dremel with a cutting wheel. I start cutting and realize... THIS THING MIGHT BE MAGNESIUM!!!!
Sparks don't go well with magnesium... Just thought I would ask before I did something really stupid! Also... is there a better way to get this thing off? It looks like it was melted onto the intake pipe!
Thanks.

The heat sink is aluminum. The easiest way is to melt it off with a torch. The aluminum will just drip off.

Thanks for the info. I'll give it a try. Roger

Roger:

Word of caution before you attempt this cutting- wear appropriate clothing and a face shield!

The aluminum can splatter and it is HOT!

Have to ask why you want to do this in the first place unless you are planning to etch and ball your own manifold.

Dietmar,

Since the heat tube isn't used I just wanted to remove it. I thought about just cutting the heat tubes off near the aluminum and leave the rest there. Is that the better way to go?

[Dietmar]

Roger:

Most organizations that I am aware of REQUIRE that the heat riser tubes and the aluminum be removed.

My questions was really leading to the fact that after spending time doing that, you still have a "stock" manifold and will have to etch and ball it to make it worth the effort.

Notice how I did not discuss that for fear of sounding like an advertisement!

Call and I can tell you how its done if that is your goal.

That's really funny Brian. We're all here to help and you have as much info on these manifolds as anyone on ther board. Jump in anytime.

I think he may not be planning on doing the etch and ball because he's building it for vintage, and that wouldn't be true to period.

[1969zeitler]

Yes... I am building it for Vintage. I am finding a lot of difference between Vintage/Non Vintage setups. The Monoposto rules don't really spell it out sometimes. It says that you can machine the manifold surfaces and remove the heat riser tubes but does not mention the aluminum at all. One of those "the way you interpret it" rules I guess. I am guessing it is ok to remove it. Roger

[remmers]

Have you been to a vintage race before? I'm sure if you go to one you can check out what everyone else has for a setup and that'll be a pretty close approximation to what you need.

Most of the rules require the heat riser be removed. It's the only aluminum component, so your safe. Many vintage guys run very competitive motors including national level mannies.
