Tuning TSS
For those of you out there with copious amounts of experience..
Please tell me if I’m all out of whack but would the more efficient setup be a low mass at high velocity striking the tophat for a quickly opening valve with a low dwell time? I am trying an o-ring that fits the recess in the backside of the tophat at a total setting of .075 with a .25 in nylon spacer in front of the hammer to increase preload a bit.
I have a thick skin tell me if I’m retarded but at least give me some advice. 🙄

I think i need to go to a different/thinner o-ring under the tophat to increase velocity. My PW is pretty much maxed out and I don’t really wanna go past what the tophat is set at. I may add some mass to the hammer ie. washers just to see. I currently have a .25″ nylon spacer above the hammer that I can switch out for steel washers. I was testing to see if a low mass fast strike on the tophat would decrease dwell time in the valve and increase efficiency. Jury is still out on that especially because everything I read on here says to minimize preload and use a heavier hammer mass. I need to recharge my funds before checking into some of the awesome aftermarket hammers that some on this forum are producing so washers will have to do for now.
You can get 860fps easily with that setup.
I just ran the first chrono batch. Tophat at .105 with large o-ring
PW at 10-0
Kodiak 10.62 gr .177
40 shots
average 640 fps
SD: 3.5
ES: 11
2800 psi shot to 2400
Need to get it on paper now and see if the tight velocity numbers translate to tight groups
BTW ProChrony sucks extremely finicky (err, err, err) I know I know its not mine. 🙄
efficiency…
MINIMIZE preload.
