Looking for data on stock turbos

Does anyone have any measurements of turbo outlet temperature (before intercooler) for given boost pressures and ambient temperature? I searched but didn't find any solid data. If you have data, please describe your setup (porting, intake...) as well. Thanks

I got something from an May 2000 issue of SCC when they did an IC testing for the project RX-7. I'll type it as it is printed:

INTERCOOLER TESTING (ON THE ROAD)---ALL TEMPS IN FARENHEIT

M2 Medium IC M2 Large IC
Ambient Temp 65 64
Intake Temp* 98 92
Peak Intake Temp[0-80mph] 105 99
Turbo out Temp* 230 230
Press. loss (psi)* 13 13
Max. Boost Press(psi)

*measured during a 3rd gear WOT run from 3000 to 7000rpm--all peak numbers were recorded at 7000rpm.

That is enormously helpful. Thanks DJF! And it came through perfectly on the instant reply notification, I don't know why it's screwed up in the post.

no problem man....actually in reviewing my post, i realized i left out the pressure loss and instead put in the boost pressure at 13psi. The pressure loss on both the medium and large was 1.1

This is the first time I've seen this data. pretty interesting on how much the M2/ASP actually works.


It would be really cool to also see this type of experiment done on different IC's (front/SMIC/ V mounts) Vs the stock unit.

I hope to duplicate the data for the V-mount setup I'm working on, but I'm not going to get to that stage for a couple months.
