Double Dark Side! Diesel & 8P
After using the car on track last weekend, we found that the cooling system wasn't up to scratch. I think this is more down to the lack of oil cooler on the car. The cooling system is always going to struggle to keep control if the oil is absolutely cooking, and I'm fairly sure the oil would be getting far too hot on track.
Got the cooler mounted:
Vent holes cut in the arch liner for air flow, and meshed to protect it:
Made up a simple lower bracket in stainless to hold the cooler rigid:
Then got the mounting finished and bolted up:
Just need to fit the sandwich plate and run pipes now, and that's done.
I'm also going to try fitting a power steering fluid cooler, for some bizzare reason the power steering fluid gets VERY hot on track, and the steering goes notchy and whines towards after 10-15 mins abuse. On inspection it appeared that the fluid had been boilling.
Some suggest this is down to radiant heat from the downpipe in close proximity to the rack, although more sources seem to say that the additional heat is due to the sustained high revs, causing the pump to generate more heat.
To combat it, I've got a little 7 row mocal cooler I'm going to mount in the drivers side arch, opposite the oil cooler.
Made a start on how to pipe that up this evening too.
This is the current PSF hard pipe comming off the pump, heading to the near side:
And this it the section I managed to salvage from a set of TT powersteering pipes I picked up a while ago:
It seems about perfect, as it'll send the pipe off towards the drivers arch, right where I need it. Just got to mount the cooler tomorrow night, then start piping it up.
