Message: [QUOTE="Charles, post: 34826, member: 103"] If I had it to do again I'd run the V60 gate or similar. The 44 is not enough to bypass the full brunt of the drive around the 38R at higher power. Right now with the 55 set at a lowly 25lbs or so lbs, I cannot run [i]less[/i] than ~80lbs on the manifold because I cannot control the 38R anymore with this big free-flowing turbine that's on the 55 letting everything out easy and not putting much backpressure on the 38R anymore. Even so.... years ago I actually disassembled the Tial 44, ground down the top of the valvestem and cut some turns off of the softest of the "large" springs that Tial makes for the 44 just to get more lift and flow. The 44 is insufficient IMO. With the 47 and an expected boost of 60+psi it was fine. With a freer flowing first stage turbine..... it's all it can do to keep the 38R at 20lbs or less, full song. It would be better to keep it at say 15 and let that 55 sing on up a little. Plus it would be nice to simply be able to run less than 80lbs, lol. Moral of the story.... look to something larger IMO.
