[QUOTE="FischerMotorspo, post: 16091029, member: 130669"] HI Guys For those interested, attached is a screen shot of a pretty interesting MoTeC data log related to the subject of temperature and thermal management discussed in this thread… it should be pretty eye opening to those not used to seeing the temperatures generated by the higher boosted screws. The MoTeC log file is from a 4.2L GT500 we built for the TX Mile with a lot of our various systems implemented on it. I wouldn’t call it a “max effort” project as we were limited with time on the build and it can definitely “go bigger”, but it was a pretty serious build with very little budget restriction. The log is from a shake down and licensing run at the mile with a stock intercooler core and intake that had our Hot Water Bypass mods and wastegate boost control mod. This car made right about 1500whp and ran extremely well during our testing, but it got rained out of the only TX mile event it ever went to. We felt it was a 235+ car easy as it was 20 mph faster to the ½ track in its licensing / shakedown runs than the record 215 mph car we ran at previous events. This pass was our 4th pass ever on the new build and was still tuned extremely soft for fueling and timing. We were still shaking it down, getting the owner and co driver up to speed in the car, and neither driver was licensed to go over 200 yet (note the big lift when the driver looked down to check his speed, and a very early shut off that you don’t see in the log). In the image, check out the engine temps relative to the blower case temps. Normally these would be the same as engine temp at best and usually higher due to the heat soak from the blowers discharge temps. Also see the air temp drop across the IC core (approx. 300*F).
