Here is what Terry posted on Aug 5th.
Hey guys, Got the M3 back finally and headed over to the dyno for a little tuning. Changes since last go around: Slightly larger wheels on the PURE S2 turbos BMS S55 intake Less octane this time around: ~95 octane and 50/50 boost juice, last time was ~98 octane and a higher meth mix. General thoughts: 1) The new wheels spool a touch slower than the previous ones but seem to hold boost better towards redline. All in all doing what they should be. 2) Sorry, I didn't take the time to swap back to the OEM intake. Preemptive answer: I don't know how much of the power gains if any can be contributed to the intake vs. other changes made. 3) I found this setup on the OEM timing curve is under advanced even at this lower octane level. Going from 9 degrees peak timing (normal timing target) up to say 12 degrees peak timing (JB4 adjusted target), keeping boost the same, resulted in a ~20whp swing at high rpm. This partially explains the heavy dyno variance people see testing in different ambient weather conditions. And just goes to show how easy it is to make hard parts like intakes or exhausts look like they are adding (or subtracting) a ton of power when they might not be doing anything. 4) Note the JB4 we have on ours has a special wire set that lets us adjust the timing curve above OEM values. No one else has this at least yet. 5) When the weather cools down I'll head back with straight race gas and see how far we can push it. I'm thinking it should do around 675whp @ 34psi in 50 degree ambient weather. Attached Images |

Awesome results, I have little doubt that Terry will hit 5's soon. I've added this to the official 60-130 list on M3post. http://www.m3post.com/forums/showthread.php?t=630463 |

Nice It is just a matter of time before the F8X will overtake the current supercharged E9X 60-130 records.
