370Z Drift Comp Car

Made a swirl pot for the coolant yesterday (as always, some of the welding could have been better but I'm a software developer not a professional welder so it'll do lol) :















Also got the rear radiator mounted and started making a proper plan for the water pump and header tank stuff:

Making progress.

Welds don't look bad. It takes time and practice to get really good. One suggestion. When you stop the arc. Just before you stop. Move the tungsten to the edge of the puddle. This eliminates the crater in the center of the puddle. If the weld is going to crack. It will start in the crater.

yeah I do normally circle it around as I taper off the pedal, but maybe not as much as I should. All of my alu welds on the intercooler and intake pipework on the last build survived fine for the last 2 years so I'm not too worried... but feel free to say "I told you so" if any of these ones ever crack

Also made a diagram of the full coolant system - partly for me to refer to as I make things and partly for other people to refer to as I know when I searched I couldn't find much good info on how to integrate swirl pots, electric water pumps, and header tanks etc.

The swirl pot is not strictly necessary but after having some issues with coolant bubbling last year I'm taking a belt and braces approach this time lol also I'll still be running the stock water pump as well as the electric pump. The electric one is there because of the radiator being in the rear (plus nice to be able to keep the pump running for a while after turning engine off)

I got about 100 yrs of experience welding exotic metals. I'm used to people coming to me for tips. So me giving tips on it just comes natural.

Finished making the header tank today

Added a schrader valve to the top so that we can use a tyre pressure gauge to check what pressure the coolant system is at whenever we want. Also more importantly it allows us to pump more pressure in if we've ever had a leak or had to take the cap off for some reason while the car was still hot and therefore lost all of the pressure (higher pressure means higher boiling point so we don't want to run at just atmospheric pressure).

Used some polycarbonate tube for a sight glass which should be ok for the temps this will see. I've seen some people just using translucent silicone hose for this but most of those are only rated for about 70 degrees C so didn't seem like a good idea to me when I've seen 120 degrees C on the coolant temp gauge in the past lol
