Hey dude.

I have been running my RB20DET at 380hp (280kW) @ 28 psi on stock internals.

So far all has been well while at that figure for 5 years now, though the engine is starting to show some signs of getting tired, but that's to be expected if running that sort of power for so long. I'm actually surprised it's lasted this long with the amount of abuse at regular track days I give it.

At the moment I have tuned it down to 300hp (220kW) @ 18 psi while I'm building my 26/30 just to make sure I can get a few more months out of it.

Hope this helps.
