Will post results tomorrow. BTW love the wheels something different than HRE's.
Re: Wheels, Thanks! I love my CCWs.

I have always had a suspicion that my car is underpowered. I mean, it really doesnt feel like it has that much power, IMO. If I were to discover this by an independent dyno would I have any recourse?

The a/f on your dyno graph RFlow looks really good. I wonder if the 2005's have a better ecu config? Yours is the first I've seen where it doesn't hit 10:1 before 6,000 rpms.

I would love to get feedback from other 2005's. The only thing I know is that a couple of days afterwards the A/F box was sent back to dynojet to get checked out. A car came in to dyno with a stand-alone computer and the a/f ratios were about a point off. Both sensors were installed at the down pipe to get reliable results. Dynojet sent a new box but said nothing major wrong with old one. Whatever that means. I will be installing a nitrous kit next week so I will do some more motor runs. The only difference will be the k&N's compared to my previous post.

SAE is a correction factor that is calculated using sensors to measure ambient conditions such as air temp and humidity. It's a SAE formula used to correct numbers made so that it minimizes the differences in a really cold dyno room versus a really warm one, or a really humid one, etc. It is by no means perfect, but that's what it's for. If you want to read more about it, there's a multitude of info on the net about it.
Smoothing is simply function that smooths out the dyno graph lines. Since power can fluctuate quite a bit (not a lot of hp, but just very often, every few rpm) throughout a dyno reading, smoothing takes the jaggedness and makes it more legible. Next time you are at the dyno shop, take a look at how the smoothing function cleans up a graph.
Hope this helps.
FWIW, my car made similar #s stock. These are tough cars, and it's funny how we are going to be taking similar modification routes although I won't be messing with any additional forms of injection.

Marcus

Hey Marcus,
Thanks for the info. So its really the SAE # that affects the "Corrected" numbers they display. The Smoothing is only for presentation purposes and doesnt affect the numbers.
Yeah.. We both knew early on our approaches were similar. Did you ever get back to the "boys" about that little project we spoke about??
