Until people understand that a dynamometer is just a testing device to measure delta gains they are not going to understand why it's useless to compare one dyno to another. Furthermore, if people can't understand why third-party testing is more pertinent than manufacturer-testing then they are always going to be 'sold' on 'real' dyno charts that specify different tunes on different days in the test comments and think that power differences are simply coming from the part installed. Basically, until people become educated on the testing processes they will continue to be ignorant of the results.
I'm not saying that manufacturers are inherently evil or intentionally trying to mislead, just that they have a vested interest in showing gains whereas third-parties only live in the data and sharing of knowledge.
I appreciate this info. I mean no disrespect in any of my opinions here. Though several people continue to insult me I have not retaliated in fashion.
What I'm sharing is simple logic. Concerning my issue with Hijinx's vdyno:
1, I do feel it shows a gain, as do others as posted on the other thread where we've been debating.
2, If he were so concerned about it being an accurate way to show the difference between the car with or without the intake, it would seem to me that using different fuel for the two logs is the exact wrong way to go about that. That only further compromises the integrity of using those runs as proof that the intake shows no gains. This seems pretty obvious to me.
3, As I said elsewhere, no dyno or vdyno is perfect. Slight changes in many variables will affect things a little or a lot. I shared my experience with this from my Subaru days, two logs taken within an hour which showed significant differences. It happens.
In the end I simply trust a real dyno, be it done by a manufacturer or not, when compared to a vdyno. The immature arguments and childish tone of those arguing lend further doubt to whether said people have any real integrity when even performing such comparisons, but even if that were not the case I still feel the same. I'd rather put my faith in those with years of manufacturing and engineering experience and multiple real Dyno's done on real cars. Beyond that, I have talked with two vendors here and one tuner and all agree that after seeing dozens of dyno runs on our cars, intakes do help so long as they are closed like the CPE.
Yes I could swap out the intakes and do logs but I have no interest in taking my car apart to prove a point that I already feel is proven.
I am happy that we have all found our own paths to customize these wonderful cars and respect the mod choices of everyone involved, along with their passion for cars, whether or not we agree and no matter how I am treated. As I told Hijinx, maybe one day we will have a beer together and talk cars, I am sure we could learn from one another.
On another note, I have enjoyed using vdyno in the last week to take a look at the differences in the curve of my tune revisions. For that it is a great tool.
