This is from the datalogger, I think the tach needle would have an effect if I was using the tach to figure it.
I'm wondering if it's a 4 cylinder thing. With an 8 cylinder if you cut one cylinder at a time your cutting 12.5% of the power. When I hit the button I'm taking out 25%.
When in neutral the motor stays within 75 rpms when the button is activated. But with a load on it. It gets cranky.
My brakes are stock discs (bonded pads) in front and back. I can't use larger or aftermarket brakes because I need to run 13 or 14 inch wheels (to keep wheel height to 20 inches)
The converter was made for a transbrake application. I'm wondering if I went to a softer hit converter. If it would be easier to hold on the line.
