Greetings,
 
Well, now that = I have the=20 temps, the next question is- how bad are they?  How high does the = air temp=20 have to be before it becomes a serious concern?  Anyone have any=20 idea? 
 
Thanks,

Went = out to measure=20 the intake air temps after the turbo. =20 The prop is at 14 degrees, and I wrote the rpm’s down, but = I think the=20 prop is probably partially stalled, so I wouldn’t count on them = being=20 correct. 

 

Ambient temp, and=20 intake air temp when first started- 90

Ran at = 22” MAP to=20 warm up, then started taking temps when it stabilized

MAP / = temp F /=20 RPM

22” / 105 /=20 3000

20” / 128 /=20 4225

30” / 167 /=20 5000

36” / 196 /=20 5500

40” / 214 /=20 5700

44” / 228 /=20 5800

50” a couple=20 seconds, no temps or RPM, but no loud expensive noises=20 either
