Right on.
Here's my rpm vs speed vs gear spreadsheet in case you're interested:
rpm vs speed vs gearDownload button should show up in the upper right corner.
Lugging is perceived below 1500rpm when stomping on it. Usually when accelerating and shifting from 2nd to 3rd... I don't actually have a tach, so this is all estimated from the spreadsheet, but I'll accelerate just over 20mph (3000rpm) in 2nd, and then hold the clutch in for 2 or 3 seconds while that 30lb flywheel is slows down enough to shift without grinding. By the time I'm in 3rd i've slowed slightly & the speed works out to 12-1300rpm. This is where I lug my way up to ~25mph (~1500rpm) before it sounds happy again. Not an issue on flat stuff, but annoying going up hills. Hence my interest in cams that increase low end power below 1500rpm, if I had different final gears (or tiny lowrider tires) maybe the bulldog would be more feasible.
In 4th gear I can go slow as 35mph ~1300rpm as long as I don't mash the gas
Thanks for the replies!
