so got new piping and a bunch of other stuff done, tuned, driveable etc. Took it for a punt around in late December. low 20 degrees at dusk, check intake temps while taking it easy driving home: 45-50 degree intake temp.Thought that was a bit high, spoke to some people and they said check the intercooler.
Bosch style plastic temp sensor fitted just before the plenum. metal weld-on bung, all stainless piping.
2.5" piping, intercooler is 600x300x80, 3" inlet and outlet. Apparently its a PWR core "custom" made at Race Radiators in dandenong. Was spray painted black very roughly by me. Intercooler sits in front of a small oil cooler, and a custom radiator behind the oil cooler. Intercool is approx 12+ years old, few squashed fins but mostly in good nick.
1) do these intake temps seem acceptable for a small car cruising around at 80km/h?
2) does this intercooler seem quality? worth replacing for something $$$?
I cant think of an easy way to test intake temps before or after cooler for comparison. Need to get another temp sensor, wiring, weld-on bung etc.
