16g with t25 WGA question

[alice]

I remember reading somewhere that people have been able to use the T25 WGA on the 16g to reduce or eliminate the notorious 16g boost creep. However, after ample searching I can not find that post(s). Since that would be a simple mod, Mrpeepers would not have taken the time to do that awesome write up on the 16g WGA modification. So my question is can you use the T25 WGA on the 16g to help with boost creep or have I lost my mind?

Hello

You could swap a bracket and rod from a TD05H onto a t25 WGA and it would help with creep (see the boost creep test outlined in the article). The t25 actuator has more throw, but still not as much as a modified TD05H actuator. I will have to measure again but IIRC it's around 1/2" to 5/8". A modified TD05H ends up being ~1" which is enough for 90*.

The reason I didn't go that route was because of the actuator itself. I haven't tried it personally, or even have concrete proof, but the t25 WGA could risk being blown open at higher boost pressure. My intent was to deal with creep without making any sacrifices. I liked the spring in the 14b and 16g, and the larger diaphragm, so I went with that. Also, everyone will have a TD05H actuator in the first place, like me at the time(or three of them ).

Don't think that this is the only way to do it though. I'm sure there are better or at least simpler ways, this is just how I chose to do it with the materials at hand.

Thanks for the kind words
