Looking for real world temp data at the intake manifold (output of the IC) with a stock intercooler during a dyno pull. Trying to get a feel if my estimates are realistic.

Anyone measuring this? TIA

 

I have IAT just before the throttle body. No dyno run data as I have not been to the dyno.

 

Typical temps at the end of a WOT pull? Do you have stock IC?

 

Yes, stock IC. I have a datalog of a run to 130 @20lbs.

 

Thanks, very encouraging as I am currently using 140F in my calculations.

 

Um...I meant 130mph, not deg F. lemme go check the datalog.

 

haha, I see. Yes, I would love to see the temp data on that run.

 

Max temp was 66°C, reached after decel. During the run, at max RPM and max manifold pressure, the temp reached 49°C.

 

Awesome. Thanks Darwin! What would you estimate the ambient temp the day of that run?

 

I edited my first post to be more specific. Ambient temp would probably have been mid to low 90s with MSL ~5000. If you download the Wintec SW from electromotive for free, I can send you the datalog file and you can view all engine parameters.

 

Thank you Darwin! I will pm my email address. Very helpful. Thanks again.

 

That's honestly a lot cooler than I would have thought!

I've always assumed something around 140F -160F when calculating air density, but as is obvious from the graph below, the difference in air density between ~120F and ~150F is actually quite large. I didn't think the stock intercooler worked that well.

That's one of the reasons why I kept it. Shawn, you have a PM and an e-mail.

 

I'd be interested to see the pressure drop across the intercooler as well.. It's definitely keeping the air cool, if the pressure drop is minimal, then there's almost no reason to swap it out

 

It's going to get a fair bit hotter on the dyno though Shawn.
