Has anyone actually seen temp testing data from afermarket turbo heat shields? I've looked everywhere and couldnt find anything. We have a couple temp probes that we used during designing of our heatshield but i was thinking about doing some more robust testing so there is some good data out there. So many people out there run no heat shield on their car and we wanted to know the difference. Your thoughts??

In the following days we will be posting up the temp numbers we have at idle (obviously at operating temp) and cruising with cruise control at 60mph. There are multiple locations we have selected and soon enough we will have the results posted!!

Stay tuned.....


So here it is, after a long day of testing yesterday we are very pleased to bring you some really exciting results! To give you a little background these tests were done on a 2002 WRX with a 2.5l block with 2.0l heads and a VF39. STI TMIC, aftermarket downpipe, and Samco Throttle Body Coupler. All of the tests were performed in one day with the air temp @ 65 F. All temps have been recorded in F. Both IAT's for pre and post readings were measured INSIDE the pipes @ the connections. All numbers recorded are true to readings and have not been modified in any way, enjoy!



Now this graph shows the IAT's INSIDE the system at the Turbo Compressor Housing Exit (PRE) to the Throttle Body Coupler (POST)


So what have we concluded, well the data shows it all! The heat shield is in fact VERY effective at blocking heat from vital parts of the engine as well as keeping the IAT's SIGNIFICANTLY lower.
