Twin engine GTP project progress thread

cause if one is good, then two is more betta

btw i dug out my spare vb so i can tear it apart and look at the boost valve.
it appears the sonnax might replace only the primary pump half?

regardless a new valve with a 2nd pump that comes in sooner shouldnt be hard to turn, at the least we can get the spring dimensions/rate for sourcing a stiffer spring
