Drivetrain HAI - still happy with it?
You of course forgot to include that I could percieve the variance in horsepower OF THE CAR, and that the software seems to be quite accurate.
You of all people should know that Math is Math and not voodoo
Thanks for trying to debunk me. What ever happened to you and your buddies saying "the onus of proof is on those that assert the positive"? Well, you're claiming the HAI does something, show us numbers that mean something!

Anyhoo, I'm still happy with the HAI and haven't seen any credible data to suggest the Alta is better. My own measurements (as well as those that Cheese did) showed an improvement in air getting into the engine. Ryphile's "this PDA dyno isn't accurate but I will try to use it to sell parts" information is interesting, but I don't see how it is an accurate test.

No Andy, you measured an increase in boost pressure, not air weight. Anyhoo, who's this "Ryphile" guy, and why wouldn't he try to sell a ton of these cheap K&N filters versus only a few of the much more expensive ALTA CAI?

That is speculation and ... as it turns out, wrong.
Anyway, if you don't believe that air pressure is a good gauge of airflow, you had better throw away the Siemens engine management system because it uses a MAP sensor (speed-density calculations) to determine airflow.
Let's take a page from the Andy-and-his-buddies book of logic: "The onus of proof is on those that assert the positive". Since Andy's already stated the HAI doesn't do a damn thing, he doesn't have to prove anything.

I'm off on vacation ... I'll post Ryephile's emails to me when I get back. That should be very enlightening indeed.
andy, you were complaining about the MAP sensor, but you won't tell me if you have any plans to create a different EMS system..or to use different sensors.
We all know you work for a datalogging software company..You have to have some sort of idea what to do differently.

Look, the HAI may very well make less power than the Alta. I haven't dyno'ed it so I don't know. Neither has Ryephile. What I do know is that the air pressure readings were better with the HAI compared to the Alta. Both offered a measurable improvement over stock ... the HAI was just a little better. Again, contrary to Ryephile's "feeling" neither macncheese nor I did any dynos comparing the two.
