Tial 38 vs. Tial 44
Disclaimer: I searched and didn't find anything.
Background:
I just bought a Tial 44 and the box said it had the 0.9 bar spring in it. Just to make sure so I didn't have any surprises, I opened it up and saw there was a big blue spring in it. I have always used this link when questions arise about Tial springs: https://honda-tech.com/zerothread?id=857805
Question:
Why does that link say the 0.9 bar spring for the 44mm gives 13.05psi but the 38mm says the big blue is for 14.50psi? Looking at the picture below, the springs are the exact same size and everything. Basically just wondering what makes the big blue for the 44mm produce one less psi than the big blue in the 38mm. Thanks for any guidance.

With the different sized valves between the two, the one with the larger valve will always flow more air at the same spring rate. It's like pouring water through a 2" tube vs a 1" tube. the 44mm has a physical larger area for air to excape. This is why the springs in all Tial gates are interchangeable. I'm sure there is a better way to explain it then I did but ya

It's lovely being able to stop immediately if not sooner.

Re: (Dunc)
The actual boost pressure with a given spring is dependant on exhaust backpressure. Those numbers are assuming a 1:1 pressure ratio. The bigger wg valve has more surface area so with the same backpressure it'll have more effective pressure pushing on the valve.
