Lost a lot of performance
Eginemasters did a dyno test of 750 Brawlers recently. DP vs vacuum secondary. Can’t remember the exact numbers but there was a noticeable loss with the VS on peak power. I’ll see if I can find it.
ETA, I’m too dumb to link it on Tapatalk. It’s episode 121. Double pumper was up 20 HP over the vacuum secondary at peak on a 500 HP small block Ford of some kind. It’s a pretty good episode.
