370Z Drift Comp Car

ChrisDrift

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

Got the new header tank and swirl pot mounted:







Also made a video explaining the full coolant setup if anyone's interested:

Need a weld positioner. Then you can do one continuous weld.

Yeah I've considered it in the past but I just don't do enough welding to justify the cost really. Before working on this 370 project it was almost two years since I'd last used the welder. Would be nice though cos I do get sick of constantly rotating pieces and propping them up in weird ways.

Slow progress recently but got most of the fuel cell cage/mount done.

My engineering friend suggested welding studs in for the bolts so that they can clamp down properly and not bend the hollow box section. Personally I think it would have been fine without doing that but I like to do things properly so took his advice:







Eventually got all that welded together and started mounting it in the car:



I know its a pretty weird and ugly setup but with the cage it wouldn't fit under the floor even if we had cut all the floor out. Then when mounting it on top of the floor I realised I needed a gap underneath it to pass an AN20 water line through. Didn't want to mount it out back behind the rear rad either because crashing isn't that uncommon in drifting lol and I figured I don't want my fuel tank right at the rear of the car where its going to be the first thing that gets hit in a rear impact.

Anyway, one other little thing I got done was welding an AN20 fitting onto the adapter that my friend machined. So now we can use that as the take off point to get water from the engine to the rear radiator







For comparison this is what that hard line normally looks like once you do the "pathfinder mod" on the 350Z which I'd previously done:



So you can see normally there's that round part that has water coming in from the engine block, but we'll cap that off on the engine side (as it is normally capped on 350s anyway if you don't do the pathfinder mod). Then we're just using that section of the coolant line as an outlet instead of an inlet now with our machined piece and AN fitting, which will then run off to the rear of the car to go into the radiator.

Hopefully get the bonnet and bumpers back soon so then can finally start making progress on intercooler mounting etc at the front end
