Perhaps you can make some dyno run at 4th gear to compare with other EFRs?

You are pushing some agenda and ignoring what is being claimed. I am in no way trying to achieve peak torque as soon as possible, I can't work with the car if I have a huge torque spike as it will become unsettled. I'm sure if I wanted to it could hit a lot earlier, but that's not the point of the tune. The claim is when 300wtq happens, let's focus on that. |

Let me rephrase, the tune is specifically not shooting for the soonest possible boost / peak torque. I run in second gear mostly on my courses, if I went for the wall of torque I'm sure this turbo could make I would consistently end up sideways, or backwards, until I get my tires sorted. I'm sorry, I just don't think its a good comparison to make at this time. I point out the 300tq delta because at that point we are still building boost as fast as possible, so I feel it is a good data point to look at. Once I get the AWIC in and a few other small items buttoned up I will get it back on the dyno and during the re-tune we will go for your goals in the name of data, we will see how it turns out. Speaking with my tuner he predicts picking up 15-20whp with the retune and slightly faster spool because I'm ditching the front mount. I guess we will see! |

You did it! I'm running around 25 psi on this, and DESTROYED an RS5 from a roll, with a 300 lb passenger. The equal length header is amazing for this too.

Once I get the new intercooler setup and a few other kinks worked out I will be going back and push it bigtime. Looking at early October for the retune right now. Depending on how things look I might actually go smaller, to the 6258, but right now I think I should be solid full boost @ 3500 which will be plenty fast for my purposes.

This!!! Welcome to the club, no need to make more "useless" low end torque |

Not really... There is no time component to a dyno graph and it is load and gear based on an abnormal condition that is never met while actually driving...

The time is when (not what time it is...lol) in the RPM band does peak tq occur, which "does" give a good indicator of when full boost is being achieved, especially if you are comparing different peoples setup with one another.

While RPM of peak torque is generally a good indicator, things like gear choice and altitude can still play a role in what the RPM ends up being.

Take a look at my build... Peak torque of 300wtq flat from 3800(dyno... Road is like 3000) to almost 7000. Obviously not trolling |

Check out Jagger racing's STI when he was racing stock-ish class with the 6258 and 430hp and 480tq. With the additional tq, you need to know how to drive it and when and how much throttle to give. Sure you can tune down the tq of your motor, but your not going to as quick/fast as someone that has more and knows how to us it.

BTW I'm not sure if the rpm (or time) when peak boost is achieved is ideal measure of spool up. First concern is what the peak boost is? For some it will be 20 psi, while other with the same turbo will go to 30 psi, so looking only into when peak boost is achieved, the first turbo will be obviously better spooling than the second one (even though those will be the same turbos...). The other thing is that compressor maps show that boost build up is not linear so we may have two turbos where one will reach 20 psi faster, but the second will reach 25 psi faster. Which is spooling better?

New tune optimized for the AWIC, we were about an hour into the session at this point and had some issues with the car getting too hot and pulling timing. I'm going to work on some ways to combat that, but overall I'm very happy with the small improvements. I was hoping for some more HP but I think that some cooling improvements and some octane will take care of that. Feels a lot smoother too for some reason, I think the AVCS is doing more work now. Probably going to try and secure a 55gal drum of e98 and mix a blend for the next go around, the 92 oct here really hampers what we can do for the most part.
Still, very safe tune so I can beat it to hell and it will stay in one piece. 300wtq @ 3k rpm! Overlay of the baseline I had done with the frontmount (RED) and the AWIC (BLUE): Here is a vf39 just about maxed out w/ Meth for comparison: More info on the vf39 here: Adam's VF39 Meth tune...TORRRRQUEEE! - NASIOC |

Very nice!!!! What's the awic setup? Frozen boost or custom made? Engine bay pics?
