Something In my #5 Cylinder?

Not sure I'm really giving up any power with the timing locked out. This procharger starts making boost at 3,000 RPM. I leave the line at 3,000 RPM. It's been 6.42 @ 107 MPH in the 1/8. The car has no weight taken out and full interior, weighs 3,600 with me in it. I'm making decent power I think.

Wallace says you are making 685 HP. That's great power, but I think you have some you are giving up? Yeah. But will it be enough to upgrade to a grid...IDK. Enough to upgrade to something you can change timing with...yeah. Enough to justify an upgrade to EFI...IDK that either. I'd have to see some prices and your spark plugs and see what they look like.
