Boost controllers.

Could you not just use a manual boost controller? Mechanical, and once set that\'s your lot?

Or do the electric one\'s keep the wastegate shut for longer meaning you\'ll get peak boost quicker? Can this not be done with a manual one?

I think in theory a mechanical one would do the job exactly as you\'d want. But I think there may be consistency/reliability issues with mechanical ones. But don\'t quote me!

I\'d have thought there\'d be less to go wrong with a mechnical jobbie, hence more reliable?

But I have no idea!

Mechanical boost controllers dont get the boost on so early as solenoid controlled types.
Hi Steve,I think we were talking about the twins still yes.

I find the Apexi AVCR is a very good boost controller,it is a seperate unit just like the Profec b.
It does not need to be set up for each gear although it can be too.
Interested to see if the seperate solenoid that Tony is on about works with the power FC.It must be worth a try.

I\'m sure we\'ll find out my friend

Add on boost control unit where the PFC controls the boost (3 bar map sensor)



Then swap to Profec (after a few more mods)



This is on a stock twin and I retained the 3bar sensor when swapping to the Profec. The boost control solenoids where swapped over and the original pipes where used.

Yep, and as I mentioned, the A\'pexi manual states that the PFC boost kit is only to be used when the factory sequential turbo setup is not being used. Because it only uses the primary setting for controlling boost, not both primary and secondary.
It\'s clearly not the correct bit of kit for stock twins. But I\'m running a single turbo.
