Had a successful session on the dyno. The Pro Flo 4 is working awesome. Able to hold rock steady AFR's from 2800 RPM all the way to 6500 RPM. Timing adjustments were easy, quick, and spot on. Being able to make adjustments while the operator is doing his thing really speeds up and clarifies testing. Arrived at the facility at 9 AM, hooked up, fired up, tested, tuned, and loaded up by 1 PM.
I showed up with 36° total advance, 12.8:1 AFR. We went to 38°, lost ground, went 34° and gained over 36°. Then tried going to 12.4:1 AFR, it didn't like that either. By looking at the plugs we didn't feel going leaner was in the cards. So I left with 34° timing and 12.8:1 AFR making [email protected]
6400 and 603 lb ft torque @ 4900 RPM. All testing on 91 octane fuel.
Was I expecting more, well, yes, but it is easy to get caught up in the internet numbers and expect the stars as well as the moon.
Will this thing be a hoot in my car, I have to think it will be! Now to wedge this thing back in the Chevelle
Oh, and by the way, I seem to have fixed the oil leak!!
