Blinkin heck!!
After I wrote a script to process the BAT sensor readings :-)
Ambient was around 30 when started, high twenties once underway. Obviously plenty of hot air stored under the bonnet after sitting for 3 hours...46 / 62 degrees at start.....
Does anyone notice the "Boost Temp" increasing during "no boost load" and start to drop when you open the throttle?
Ambient: 28
Intake:38
Boost:47 (increases to high 50s when no boost, downhill etc.)
Yeah i have to make a heatsheild for my SRI, after having my car Dynoed yesterday i was told that out in traffic the intake quickly rose from 35 up to 60 very quickly
looks like i win the prize
90 degrees intake and boost temps when it was that really hot day in sydney (at least 40 degrees) and i was stuck in traffic for 30 minutes that was moving just enough for it to not be possible to switch the engine off
only had a short ram on the car at the time too
i was afraid to actually go over 2000rpm... if only i had a camera
yeah i get that all the time
the temp will drop a few degrees when you start moving, but then it will increase a few degrees when you cruise at low rpms, even with good airlfow
open it up and the temps drops again
I was at KFC drive through lunch time today and it had been raining all day and night so ambient temp was like 20. There was a considerable wait time and started to realise that the bonnet was smoking. Got freaked then realised the intake temp was 70 degrees and was the cool rain hitting the bonnet.
