I've got the heat exchanger in the spare wheel well for the W2A intercooler system. It's an ebay special, 3 core Datsun 280Z rad. No way was i spending another $700+ for a PWR or Plazmaman unit. No one's going to see it, this will work well i hope. Got a mate to add some sheet metal to the fan side for improved air direction through it, and weld the filler neck and a few other things.
After the boys at CXC Racing in Narrabeen mounted this, the motor of the 16" thermo fan sits a bit lower than hoped. Gonna try and space it up next week. Depends on how much you can see it from behind. The rad is rubber mounted and the pinch weld has a rubber flap surrounding the fan. Engineering wanted some support due to a large hole being cut out, so 4 pieces of 25x3mm flat bar were welded in at north, south, east, west.
It's going back on the hoist next week to have every nut and bolt tightened up, and give the underbody another lick of stone guard to cover the burn marks from the cage install, the flat bar above etc etc
Few more pics of the engine bay fab work. Probably should explain the setup, as there's a few caps and bits and pieces going on here. The reservoir on the left is the W2A intercooler reservoir. The 2" cap and breather in the middle has a section of 4.5" pipe welded in separately below it. This can be filled with dry ice pellets come summer at the drags or circuit or if i simply just feel like it. The pressure cap is just for system pressure, yes it's not the highest point of the system, but this can be solved by using a piece of hose and a funnel, higher than the cooler in the middle. Plazmaman usually sees the rad cap for the system welded to the core or have a separate filler neck, but space is obviously becoming an issue. Believe it or not, there is a fair bit of clearance between the intercooler and the bonnet. Closes perfect.
CXC did a good job of using ally donuts to construct the plumbing between the cooler and the throttle. The tighter bend is a slight air speed killer, however i'm expecting the short journey of the turbo plumbing to spin the 3582 fair quickly.
I asked the boys to design an air box that was mirrored to the intercooler reservoir. I also specifically didn't want button head cap screws on the top as a lid, really going for a smoother look. So yes, i'll have to take compressor intake plumbing off, and unbolt air box to clean air filter. But happy to do this as not cleaning air filter every week. The design of the box should be very effective in keeping engine bay heat out.
Overall very happy with the design work of the fabrication. It's not what i wanted 100%, but it is hard to describe exactly what you want to a fabricator without the aid of a 3D modelling system or a 3D printer etc.
I will be pulling some all nighters next week to get her ready for Datsun Day and dyno. She's off to paint this weekend for a few touch ups over the years from building, and to cut back paint. The paint is still of the gun. Won't be cutting dead flat, it will take too long, but should look a million bucks after.
