Cooling Head

[Racer 1966]

Well guys,with new thread count being down and no VRC racing i get bored in the evening. I happened to have the cooling head off of my Savage and was tinkering with an idea of custom machining it.

Here's what I.came up with, what do you all think? Should I machine it?

I know it'll be fragile on those pointed tips,but it's really a shelf queen design. Rolex? It is a machinable design I can easily do. The pic is actual scale for the HPI "chubby" cooling head but could be adapted to others.

BTW, it doesn't matter what yor answers are, it will get done eventually ha ha ha :yes:

I say why not? I'd love to have the tools to mill out parts.

If it's a shelf queen heady only I think it's totally awesome. I think the cooling properties would be out of whack though if it were used.

I agree, for a shelf queen I think it looks great! For a runner, I wouldn't do it. But I really like the design.

And if you are bored I can send you more parts from my Ricky bike

I think that's an amazing design. If you make a larger head with that pattern you could get the same amount of cooling.

pfft... I don't think cooling would be an issue at all. Just too fragile if you were to go belly up.

You don't think you'd lose some cooling effectiveness in the exhaust area? The rear of the chamber is generally already slightly hotter due to the nature of things. I would think the lack of surface area may exacerbate the situation. But hey, I'm no engineer.

you'd be surprised at how much of the cooling head you can lose and still keep temps good. I have seen several buggies break their cooling head off or in half and still come in under 240F after 30 minutes of racing.

That's very interesting.

I think it's a cool idea and would probably run ok like others said, but be a bit more fragile.

Case in point:

That's a TRX engine even (usually hot runners). Runs around 240 all day long. Too bad my purpose was to avoid cracked crank cases only to find out that it's chassis slap that's been causing my issues... Meh, live and learn!

Like I said before, this is the "chubby" head which is way larger than the stock head anyway. I think it'll be just fine if I run it. I'm not an engineer either, but I know a lot of things engineers say won't work will in fact work just fine.

Engineers....don't get me started. They should have to use and work on everything they design for 2 years before their great ideas are released. i work in a plant full of "It looks good on paper" numbnuts....
