I must be super safe with 13.2 at 7k @ 27 psi on race gas. I guess I should verify actual vs indicated timing. Lol.

Yeah that's safe especially on e. Staying under 20 on pump is safe but still I'd run atleast 22

Mine made 542/441 with that timing. I suppose my torque would shoot up with that much more timing though. |

After the rewire and 43psi base it was still not up to par. Now with the base at 55psi the IDC is 85%.....they're now basically flowing like a 1600cc. |

That thing is beastly! Loving the power band. Congrats on the new found power.

interesting. seems to spool 500ish rpms later than this rotated unit...is that just because the run started a little later? what size exhaust housing do you suggest? how does it do with iwg vs ewg?

The ATP turbos come with only one exhaust housing. IIRC it's roughly 9cm. Most of the ones I've done we're on EWG. -- Ed |

Why does everything spool slower on the dyno than the road? Can you not adjust the loading on the dyno? I don't get the benefit of playing with dynos so I don't know all the ins and outs but I thought that was an advantage of a dyno is to be able to hold set speeds and measure power changes and also to vary the loading.

EDIT: not all dynos are load control dynos either. Dynojets and some others are inertial dynos, some have electric power absorbers, eddy current brakes, etc... lots of variables |

OP I am surprise you are running such low timing because Ron has advice me to crank it up a little bit. I am running about the same timing and I don't think I will have issues and gain power if I decide to crank it up to about 26*. I love your dynosheet |

My question would be was there actually any power gained by running timing that high on your race map? I know you can get away with it on E85 but there comes a point where more timing doesn't add power. I haven't seen much benefit going that high even on smaller turbos. |

Awesome!
I run the same block on a stock location ATP3076r. I want to do e85, but I recall the RS Street block limitation was given at 600hp at the crank. Curious on your thoughts on that? Or do you not care? |

I rarely run anything over 23-24* anymore on any setup, unless its asked to be pushed.
And I never said that this tune was conservative. I said that I dont consider anything making 500whp on a subaru conservative no matter how you slice it. We're just asking a ****load out of these things. But I said you if you compare the timing and AFR values to others that get thrown around that you could say its on the more conservative side of things. When it was at 480-500 he was saying it was "blah" so i turned it up...and it was already at 27-28psi, so the rest came from the timing. Obviously the more power you make.....the less time the motor will last. Its pretty safe to say that if everything was perfect on the car (oiling, plugs, leaks) that it would last longer taking out 2psi and 2*. Alot of it comes down to keeping the oil fresh and being anal about watching the wideband for leaks. I didnt want to run 28psi....i was going to stop at 26, but he had his mind set on 28. As juan pointed out these cars can last lots of miles at the power levels and utlizing the timing, but you have to be anal about your car. |

I made some really nice power on a stock turbo 04 STi last week. He is hoping to get down the 1/4 pretty quick with it but he's a bigger fella so that isn't going to help anything. Sorry for getting off topic here OP. I am very impressed with your build and numbers. You've got my reconsidering the turbo selection for my '11 STi now. I'm really impressed with the spool and flat powerband. |
