Magnesium replcement intake manifold and engine mounts
As some of you might tell, I'm on a bit of a weight reduction crusade right now.... My next idea is to have cast magnesium replacements for the intake manifold and engine mounts. I'm hoping to have a total reduction of 25 to 50 lbs in the engine bay, which is significant. I would also be willing to supply these to other interested buyers. I could also port and polish the magnesium intake manifold for interested buyers. I was considering the intake horns, but their initial weight is so low (2.5 lbs) that the cost of tooling for them would not be worth the investment.
Any ideas/ comments?

Yes please.
Considering it would not replace the rubber (or if replace, urethane) portions of the mount, I am all for it. My only concern would be the structural integrity and durability of the piece. Would it be comparable to what it replaces?

Magnesium is a very strong material, comparable to aluminum. The iron our mounts are made of, which is very heavy, is overbuilt for our cars. I'm sure other people can give their opinions, but I'm not concerned.

Actually, this is very easy. Usually, you would have to have a tool made for a part being cast. This is the most expensive part, as tools can cost as much as $10k, for small ones. In this case, we already have the part we want to duplicate, the OEM one. That means there are no tooling fees and it is just paying for materials and foundry production cost.

I'm not sure yet. I'm going to talk with the foundry once the weekends over. I still need to do the math and see if it can take the load, but i don;t see any reason it couldn't...

I have a stock intake manifold right here that I just put on a scale, it's surprisingly light at about 4-5 lbs. Bolted to the head it appears to be heavy, I was very surprised when I took it out of the box for the first time. I don't know how much lighter you can make it, but good luck. If you happen to cast an aluminum 1.6 Tritec block, i'd be in for one of those.
BTW, the stock intake manifold is aluminum.

I could tell they were aluminum by looking/feeling them. dunno if that's my special power or not. im good at determining what metal something is. you could have done the magnet test i guess(ferrous or non-ferrous)
If you want to make stuff out of magnesium, how about either the front or rear subframes? steel is a neccesity for those eh? i see.

Some of the highest power, most durable engines in the world are aluminum. Just because it's lighter than cast iron, doesn't necessarily mean it's weaker or any less reliable.

how to you spell Porsche? of Ferrari (these are a bit pricey for daily drivers in the repair department, but they don't even run iron sleeves, they run chrome plated alloy sleeves in a alloy block!, although, that may actually be the porsches that run that, i was talking about it with a friend the other day, and now cant remeber which of his cars he was talking about). By running iron sleeves, you dont have to worry about wear, and alloy isnt as fragile as iron, which means it MAY actually last better than iron in high hp engines, dont forget, there is alot of differnt aluminums out there, a356, 6061, 6063, 7025 (or something), then there are differnt heat treats, usually t6 for alluminum, but others are available.
An alloy block would be loads of fun!
