Ok! back to the original thread, and my recap from the beginning.
Went to test fit them, and discovered my offshore squirters were actually out of spec. Meaning the fuel shot from my squirters was hitting the boosters at differing angles. w/o the plates, it wouldn't matter. With the plates, it has to be lined up properly. Thompson was prompt in getting back to me, and advised to try actual holley brand squirters. I dug out an old parts carb with similar sized holley brand squirterts, and boom, went on perfect. misted the fuel down and pretty like its supposed to. From all the data i can gather in my garage, in park (not a ton)... they don't seem to hurt anything at all. We'll see what they do on the track next year. I don't have any major performance modifications in store this winter, beyond a radiator, so I'd say if i run my best ET ever early in the season, they are doing something. To test that theory, i'll pop them back off at some point and see if it responds negatively. I do recommend going 1:1 linkage on a double pumper. I do not like how the fuel trickles down the secondary plate with a progressive linkage. Thats just my opinion, and I have zero backing to indicate if its any different whatsoever from a normal secondary booster/squirter. on a 4160 this obviously wouldn't be an issue. you just need the quick/fuel pump shot from the 1:1 on a 4150 to fully "mist" the secondary shot off the power plate. that was my solution vs changing pump cams to hit "harder"
here is a video for the patient followers! this is 1:1 linkage. with holley branded squirters, waiting for the track next year.
