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.
