I've been thinking about this since I 1st. dyno tuned.
When my car is at 150+ mph, the air cooling my radiator is 150+ mph.
Now when I dyno tune, then put a 4 ft. dia. fan in front of my car & call it equal.
Now on an N/A car, as long as the engine stays cool (4" fan in front of the radiator), everything should be OK
But on a Boosted car, it's a whole different story. Consider this: 150 mph. Whats the cooling effect of 150 mph? Consider Dyno Tune: Will the 4' fan provide 150 mph air flow through your SIC/DIC?
Ansser: NO
My Conclusion: The SC motor will put out more hp/TQ @ spd, than it will on a dyno. All because of INSUFICIENT air flow to the SIC/DIC on the Dyno.
Opinions? Conclusions?
