Boost Control
Trying to see what people are running and why. Trying to understand pros and cons. I planned on a manual boost controller however my tuner said he is against them (boost spike). I would love for the community to weigh in.

Do you really need a boost controller?? I am not going to be running one as I am only running 10psi

This seems to be one of those things were people have no problem spending the money on the turbo kit and then try to cheap out on supporting mods.
The electronic one is going to be more precise, don't skimp out here.

This is a fairly common mistake that people make when trying to extract maximum performance out of a turbo installation. Just running wastegate pressure only is perfectly acceptable but you will be leaving a little bit of performance on the table. It's important to understand how wastegates work. I won't go into a lot of depth here but the TL;DR is that the wastegate actuator will partially open several PSI before it reaches the equilibrium pressure it is designed for. This will slow the rate at which the turbine spools, making it take longer to build boost. If you use an electronic boost controller with a solenoid valve that blocks the boost pressure from getting into the wastegate until target pressure is reached the turbo will spool faster. How much faster? Is it worth the cost? that all depends and is a much longer discussion.
If I wanted to run 10PSI of boost I would opt for a lower pressure wastegate actuator (say 5-7PSI) and pair it with a nice EBC for maximum spool.. but that's just me. Edit: Most FA20 builds can't run enough boost/make enough power to justify an external wastegate but there are some interesting "upgraded" internal gate actuators that have both an upper and lower port which is really the BEST way to control boost with an EBC... Just blocking boost to a single port can only get you so far and you will still get the gate creeping open before your set point. A two port actuatator allows you to use boost to FORCE the wastegate to stay closed until you want it to open, regardless of the spring strength. -Matt |

Lot of good comments on the EBC. Any strong supporters of MBC? or wastegate only?

EBC's can do a lot more than mechanical controllers (obviously). The TruBoost for instance allows you to set alarms, has auxiliary outputs that are triggered for certain conditions (e.g. an alarm output, triggered when the alarm goes off) that can be wired to whatever you want... It allows you to set the "spring pressure", which can help you improve spool time (and/or overboost, be careful).
As mentioned, it has fail-safes in place if something does go wrong. I would recommend getting an electronic controller. Save yourself the hassle of running line from your engine bay into the cabin of your car and back out to the engine bay (manual controller). |
