Got protuned and the results are...
311whp and 330tq! Car is a 06 STI with Helix 3" Downpipe, 3" HKS Carbon-TI cat-back, K&N Intake, warlboro 255 fuel pump and of course Cobb Access port. Heres the dyno sheet:
This was done on a Dyno Dynamics dyno and I am pretty happy with the results. Thoughts?

So Al had no problems with the boost spiking as soon as you switched to the Helix?

Invidia V3 I believe. It is the version with the splitter plate in the bellmouth. I am glad Al got everything sorted out for you. I have never been a fan of the Divorced Wastegate downpipes or the downpipes with the splitter in the bellmouth. -Matt |

It was the V2 Invidia so not the one with the divorced wastegate, and yes stock turbo.

V3 is what the original post says.

I'm surprised to see that they are still using an unrealistic correction factor on that dyno. Regardless- the graph looks nice. The real number is 279.9 hp though if you take off the inflated 10% CF Al has been using.

I don't get how you can say we are using a "unrealistic" correction factor

You are at sea level- if you are adding 10% on top of the calculated correction factor that is unrealistic.

As I have stated before, we have adjusted our dyno to read similarly to local dyno jet dynos - we feel this is a more meaningful and useful figure The main point is that we keep the correction the same before, during and after the dyno tuning Our # 1 use for the dyno is as a tuning tool - not as a bench racing machine Regardless of the peak power # a skilled and savy reader of dyno sheets can draw many useful comparisons by looking at the shape of the curve and the relationship between whp and tq |

What is a stock sti baselining at on your "adjusted" numbers? Believe me, I am perfectly aware of the point an usefulness of dyno tuning. I do agree that we are just looking for gains between the start and finish. My main concern is that customers who have not researched to find that you guys are artificially correcting these numbers to read like a dynojet would possibly expect other DD dynos to read these same numbers. Then with those of us who are using honest corrections on our DD dynos post numbers they look artifically low to an undereducated customer. It just rediculous to me to take real numbers and overinflate them for the sake of comparison between other dynos.

Wow, the numbers ARE high. Nice looking sheet though.
My JDM 2.0L sti with the similar mods is only reading about 240-250whp on an uncorrected dynodynamics on 1.3 bar with piss gas. |

As far as I am concerned as long as we leave the dyno calibration constant it does not matter which setting you use. Just for your refernce we have had many customers who have gone to dyno jet dynos and their results are much higher than on our dyno. Here is an example from today http://www.evolutionm.net/forums/sho...d.php?t=245304 For myself it is easier to just try and get our numbers close to a Dyno Jet value which most of the USA population is familar with. This does not mean that everyone has to follow my approach. I dont like telling every customer "this dyno reads much lower than a Dyno Jet" This way the number represents what I feel is a fair Dyno Jet approximation - yet with all the advanvced resolution and tuning features of the superior Dyno Dynamics. |

The "real number" is the number that corresponds to the correct trap speeds at the track given the weight of the car. From my experience the uncorrected dyno dynamics dyno gives those numbers.
It's interesting to see the departure from what you said in this thread: Quote:

All from that thread. So just to be clear exactly how much are you now promising to correct all the numbers by? |

When we first got the dyno we were running it with zero correction After everyone was complaing how high the numbers were I decided to try and adjust the dyno to read very close to other local dyno jets We are still on the low side of what a dyno jet would read - for example the customer I posted about above who came in yesterday with a IX that made 299 onm our dyno and 320 on a Dyno Jet. I would rather be on the low side of a Dyno Jet but still closer to a dyno Jet number than what most people are used to seeing from a Dyno Dynamics Recently, I have made a lot of changes in the dyno adjustments A few are - we are running in 4th gear now instead of 3rd and we are using more load In any event, we are progressing towards having the dyno load very accurately to a real driving road load and also trying to get it to read a number close to a dyno jet The purpose of having a fully adjustable dyno is to adjust it to get the best tuning result possible |

Why would you even attempt to adjust your correction to compare it to other local Dynojets? It's still pointless. As Adam has asked, what does a stock STI put down on your dyno with that same correction factor? That will give a better idea of how much, if any, your numbers are inflated by.
