LDT Tappetless RPS

What have you guys found to be the RPS limit for LDT tappetless cylinder heads?

I asked my Chinese friends ,and they have no idea

I was told indirectly by LDT they support 30rps… but I have seen a few builds around 40rps using them quite successfully.
No personal experience yet- but I do have a build I am trying to finish that will be close to 40rps using one here at the moment… just need time to finish it… and been waiting on a few annoying crucial small parts

Thanks. Yeah 30 sounds like a safe number you’d expect LDT to say. I should’ve mentioned for context that I ran them on 30-35rps and it was fine. 47rps DSG seemed like a no-go and I chucked in an apache instead on the 0.8mm spring.

Across 3 LDTs I’ve found the o’ring seals to be quite tight. A tad bit too tight in my opinion. I reckon there’s some unnecessary resistance, leaving a little bit of FPS and nozzle return speed on the table. Just thinking aloud - they do get the job done.
