top radiator pipe - empty
yup just checked in the dark and it's too easy to squeeze the pipe so the rad is at least partially empty. Oddly enough there is plenty coolant in the pressure cap area so fingers crossed. Either way I'm going to see if I can source and get fitted a radiator this fine early morning. Chances.... well 50/50 lol

funny old world -
ok so been monitoring the air intake temps really really closely and found some weird stuff happening. Under hard boost conditions the intake temps are well down on the std air to air unit which is to be expected.
However at idle the intake temps rocket from high 20degC to very quickly over 50degC! Now a chargecooled lump should be much more stable than that so it got me thinking about the coolant pump I got cheaply. So I borrowed the recommended expensive Bosch unit and impressive though it's flowrate was the temp control at idle was no better.
The kick in the nuts is that when the cc pump is disabled at idle, the temps rise no differently that if the pump was running!!! Beats the hell of me. In an even more mind puzzling (for me) trick by raising the revs from 750rpm to 1200rpm while still in neutral and sat still, the intake temps fall back down to something reasonable. Going to do some checking on the cc coolant temps and see what they are doing cause something aint doing the job that was expected of it :-(
Under hard boost the chargecooler works almost as expected and way better than the std air to air unit. However there is something amiss and solving that will give us better results all round.
On another note, the Mongoose exhaust was fitted. It's a fair bit louder and has a drone at 3-4krpm which isn't ideal. It does sound well hard though so we'll see where it goes from here.

pah!
indeed life has once more given me a kick for modifying my car. The nice shiny alloy radiator I bought for the pre-rad has a HUGE design flaw in it.
The end tanks are plastic, cheap cheap plastic and have a brass insert for the temp switch. So There is me screwing the blanking bolt I have into the insert. I get to the third thread and twang. The brass insert is twisted in the holder and the end tank is scrapped. So the rad no longer can be used.
The supplier tells me yeah it happens a lot! Go to a local radiator specialist and they'll swap the end tanks or fix the current one by removing it and fixing the insert. Except of course when I ask the locals they say, nope can't be done but bring it in we'll see what we can do. What a crap design.
