Rb25 Turbo Upgrade, All Dyno Results

  • Please log in to reply
1079 replies to this topic
With so many threads about turbo upgrades for RB25's i thought itd be a good idea to start a thread that shows results only, as the results from various threads are scattered everywhere. Everyone has there own ideas about what power they want so obviously there isnt ONE perfect turbo upgrade for everyone.

Please post your RB25 dyno graphs only and state the following:
-Engine management
-Boost ran
-Fuel used (pump or special)
-significant engine mods (eg cams)

The idea of this thread is to be a quick reference to various turbo's performances on RB25's, not to be a discussion thread.


(If this has been done already let me know, but didnt come up one in search.)

Has someone got a reference dyno sheet of a stock turbo'd engine? That would be good to compare against.

And does someone have a rb25det hi flow dyno result that they would also like to elaborate a little bit more on.

I dug this up from an old thread heres the thread with talk on the hks2535,2540 & 3037.

Click me

And here is the hks test chart for 2510,2530 on rb20det and the rest 2535,2540 on a R33 rb25det.Very interesting and has helped me to answer some of my quetions.All tests are done at 1 bar of boost.

Click me

There is a larger range than that there too with tests done on other cars as well.
