That's VERY interesting Phil, seeing as an ex-ITAC member(s?) claimed 100hp out of an ITB legal A1 GTI. Hard to believe that you're only getting 1 additional hp, w/ 2 pts of compression, and a larger throttle body.
Now Bill, I would expect you to have a better understanding of dyno data than this. Actually all of you, as this has come up time and time again.
I can take my car and run it on one dyno and see 101hp, and take it to another and see 115hp. If the dyno operator does not manage the equipment and other variables consistently you could see swings of 5 and 10 hp on the same dyno. They are great tools for optimizing what you have, and validating improvements when you make them - provided you control the variables such that you are only measuring changes in the engine output and not environmental and/or dyno setup variables as well. However unless accompanied with equivalent data, in equivalent conditions on the same machine from a known good stock example, a dyno number tells me exactly nothing about the gains, or actual power that a car makes.
This is the root of my request, EVERY SINGLE TIME the conversation started up about the process, that we develop a minimum standard of acceptance for data that we use to say 'we know' something. The best answer I got was 'we have', which honestly isn't much of an answer.
The reality is that, in this light, on track side by side accelleration performance is quite possibly a more reliable source of data than dyno sheets from different sources. Put the club's DL1 boxes in the cars and go racing, and a good analyst will be able to deduce relative whp from the data and the weights from tech. BUT that is another story for another time because 'we don't do that' in IT.
Don't get me wrong, I'm not grousing. I'm over this issue completely. Some cars get fudged when the process is used by changing the inputs, some cars get fudged situationally by not being able to be reviewed/changed by the ptb, some cars get a benefit by being processed at std power gains when they make more, some cars get a weight break because of a clerical error when they were initially processed, some cars get extra weight because of a clerical error when they were initally processed. There is plenty of 'noise' to go around, and yet we have a class full of competitive cars with good racing.
Sure I think we can do better, and I still think at some point we will, but I am out of energy to pour into this debate and situation, and am just going to build the heck out of my car and try to win races.
