some relevant info from another thread on this forum.
Installed an oil catch can. Appears to make a difference.
1) when took the inlet side pipe off, it was dry inside. In the past there was always oil inside.
2) Notice the max preIC temps when hard driving, high rpm, this is when the most oil would come through. Shows in the comparison between MAX temps at pre IC. However, RLS IC effectively takes out most of the heat from blowback according to data with or with out catch can. Didn't run the w/o can + stocker test.
Prior to current run, car hot from sitting after previous run to gas station & parked for about 30mins: roof 29C, pre 50C, post 50C
Compared to previous test with out catch can:
Ambient 26~28C, Relative humidity 87%
Prior to run, cold car: roof 28C, pre 30C, post 30C
(To mimick the previous test, I drove the car around for 15 mins on hwy to get similar base temps/conditions on both runs. Interesting to note RLS test was in late afternoon. Stocker at night. It was cooler at night. I couldnt work fast enough
)
Tests with oil catch:
RLS
Ambient 30C
Humidity 74%
Stock
Ambient 28C
Humidity 78%
Hard drive top speed 117mph, 5mins, 2nd ~4th to 8krpm (same route last test). Didn't do the hwy test again as difficult to mimick a similar run with traffic. In anycase we are probably more interested in how the IC performs during spirited driving. Heat soak properties can be inferred from the data and applied to efficiency in stop and go conditions. Later when I get the fans on, will do a comparison for stop and go.
Here is an overlay of pull #2 of each hard drive log file. The shift points are almost identical, so the overlay is for the two VSS traces over time, rls vs stock. Same road, similar temps (see details in "intercooler flow study" post).
You can see that the rls Intercooler VSS (solid) gets to a given speed faster than the stock intercooler does (dashed line).
