I never did back to back testing with JUST the spacer, but I do run an open spacer on my Weiand dual plane with a carb, and then with the Fitech EFI. I then did some minor plenum work and cut the divider down. Here is my dyno progression if it can help at all. I've also switched to an Air-Gap this year, and it seems to run the same as the Weiand.Does anyone have any dyno info on a spacer on an rpm air gap for big block. I told my guys about this and they do not think it is worth it. Like to see what the members here have found.
What is your total combination? Are you ready to dyno? When will you be going to the dragstrip?Does anyone have any dyno info on a spacer on an rpm air gap for big block. I told my guys about this and they do not think it is worth it. Like to see what the members here have found.
Must be because you have a stick carIf I do 4 runs at the track, my MPH will be different on all 4 runs. No changes in parts or tune. No way I'll accurately be able to measure the small power differences from an open spacer.
That's true mine is a stick car. Though I've had days where it could be a bracket car. In any case, it's extremely rare to see anyone pulling mph's down to the tenth back to back, let alone over 4 runs. There are just way too many variables. A dyno will be a much more accurate way to measure small changes. A spacer might be worth 5 horsepower + or - in most cases, and you will pretty much never feel or see that difference at the drag strip. But if you find 3 or 4 different ways to gain 5 hp, you will start to see those differences.Must be because you have a stick car
My car is pretty consistent at the track and so is the gold 69 SS
