Default Engine is done

Engine is done. Dyno'ed at 562 hp at 5600 rpm and 578 tq at 4100 RPM.
I was disappointed that it came in below the target set but doubling back to correct it would take time I do not want to spend as the summer slips away. Given more time on the dyno I think more power could have been realized but I could not stay longer unfortunately. I want to have it tuned in the car on a chassis dyno which is more important. I'll see how I feel about the driveability and power before I do that.

An interesting test we did do was to run the engine with and without the air cleaner. It is not an exact test because adding the air cleaner richens the mixture. So you would really want to make adjustments for max numbers with the air cleaner on and off.

I got Acton's Maxx air cleaner base, a K&N filter and K&N 9" Extreme round top. I also will have a Turkey Pan.

The Numbers came in at 556 hp and 575 tq at the same RPM's as above. Any filter is going to have some effect but for the small size of that filter (9 x 2-1/2 tall with the Extreme top) the effect was minimal.
