why everybody use two 44mm wastegate? can i use only one 60mm wastegate?
what is the different?
thanks

The 60mm produces better grammar lol

It all depends on the application, divided housing or not, how much control you are looking for, turbo size etc.

FWIW I'm running 2 38's on a divided 74mm turbo, instead of one 60 that would have to be merged, or two 44's that would be overkill for what I'm trying to do.

Cause your car is slow

simply put, larger WG's divert more flow. so if you need to divert a lot of flow (ie, low boost on a small turbo) its time for a larger WG.

I had a 60mm on my kseries sidewinder manifold and i really liked it. It would stay at 13psi all day long running off the spring on a 35r. I even switched to a smaller spring for a bit 7psi and that's where it would stay no creep or any issues. I am however changing to 2 46mm(precisons) on my divided manifold setup.

I originally had one 60mm and could not get it to stop creeping. It would not make less than 18 with a 10 lb spring. I switched to two 44mm with the same spring and it will run off the gates now. However, some people are able to run the 60mm with no issues. I believe it will work if the placement is perfect.

single MV-S would be fine
