I think everyone that knew I would be dynoing my engine asked me "What do you think it will make?" There is always a lot of talk and banter about the "number" one gets after dyno session. I've maintained all along that I wasn't really worried about the "number", I just wanted a lot more top end power than I had before and the engine to be just as reliable and street friendly as it was in it's former form.
My builder got a late start today and had a few other things going, so we didn't get going with the pulls until after 4 pm today. We talked about holding off until tomorrow and starting over but the weather is going to turn bad and there is a small football game I'm fairly invested in starting at 3 pm tomorrow, so I talked him into just making a few pulls with it tonight, then loading it up and taking it home. It is now sitting on my shop floor...
The engine fired right up, no issues, Yancy adjusted the idle air screws just a bit and broke the engine in before I got there. Once we decided to make the pulls tonight, it fired right back up again and he put the hammer to it once warm.
After looking at the sheet, I was pleased...really pleased. We talked about a few things, discussed some options, the put my air cleaner spacer and air cleaner on it and made another pull.
It really REALLY liked the air cleaner. Yancy said it is most likely due to the spacer and filter smoothing out the airflow before it got to the air horn. It was a bit fat on the top end on the first pull and that evened right out on the second pull with the air cleaner in place. I should also add that this was done with my 1 5/8s mid length headers installed and about 3' of my exhaust head pipe attached to them.
I could post the peak "number" it hit, but that really wouldn't tell the story. What really pleases me about the engine is the torque curve down low AND the peak HP number up top. I'm also very happy that the engine idles smooth as silk at 825 RPM and the air fuel ratios look good across the board. The engine is ready to drop back in Barney and rock, nothing else needed.
Maybe I should do a poll...
Everyone here knows what we put into the engine, what do you think it did?
My only disappointment is in our hurry to make the pulls, Yancy forgot to clear the screen that shows the torque and HP curves...so that screen showed the last 50 dyno sessions he's done along with mine, so it was unreadable.
