Manual boost controller
 

Do these work effectively and are they safe?

Imran

had 1 on my 93wrx and was set up on a rolling road and did prove effective,ran the car for 6 months and was fine.

i would say they do work and are saft if the set up right and by someone who knows what there doing im runing one at the moment but it was fitted as a last resort to get the car mapped it will be changed when the car gets its next round of mods

At the moment my car boosts to 1.3 and then tails off to 1.1 nearing the redline. Will the MBC allow me to hold the boost at 1.2 or 1.3 bar and not drop below as the revs climb?I'm looking to get a Turbosmart MBC off a member on this forum so i just want to make sure its going to help me.
Apparently it also enables faster spool up too??

Thanks,
Imran

Anyone??
