[Shop-talk] Adding a tube into aluminum manifold

[Jack Brooks]

Darrell,

I used the stock coolant locations and piped outside, instead of under the manifold on my TR8 with an SD1 3 piece intake.

I can provide pictures if that helps.

Hi Peter,

Thanks for the reply.  Is propane or MAP gas enough heat for those rods?

I forgot to mention, the pipe is 5/8”.  I could drop down to 1/2” (that’s what I was going to do in the copper, then up to 5/8” with a brass hose barf).  But since I’m brazing it, would straight threads be OK?  Technically, there is a 5/8” NPT size defined, but I’ve not found any taps or dies in that size.
