| in the link you posted yesterday. The measurements of temp were performed By Harry (ztunerz), discussion is from the author of the thread. "I also have some 3rd party results concerning outlet temps of stock intercoolers vs. GReddy vs. Stillen. ambient temp 70-72 degrees, 1 hour difference between intercooler swaps Stock IC 0-120 mph
1. 175 F
2. 215 F
3. 235 F Greddy SMIC 0-120 mph - stock air guides
1. 130 F
2. 140 F
3. 145 F Stillen SMIC 0-120 mph - air guides used
1. 140 F
2. 145 F
3. 145 F I believe that GReddy's did the best on the outlet temperature tests because the car used during these tests had a stock fascia. The gills in the stock fascia don't allow air to get very "high up" on the intercoolers surface, so a shorter intercooler with a deeper core will get the greatest airflow over its entire surface. So while the top of the Stillen is probably being heatsoaked from a lack of airflow (even with the airguide), the entire surface of the GReddy side mount is getting air.
Finally, I have some efficiency data comparing HKS to Stillen." If the author suggests that the Greddy's did better than Stillen because of size and direct air path over the majority of the charge face, what do you think the results would be for the Godspeed? They have a massive amount of wasted material at the top that is not receiving direct airflow...even with a duct. Ducting doesn't work well when it starts small and gets larger. I know you said you were going to do a dyno with Godspeed but I would argue that a dyno is useless information. If you want to test the Godspeed intercoolers buy a thermocouple and plumb it before and after the intercooler. The measure of an intercooler is how much it can cool the air with minimal pressure loss...all the other comparisons of size, charge face, ambient air face are useless. Just my opinion, but I own both Greddy and Stillen intercoolers.
